BMW X3 2019 — Reported problems

Oil pump failure after 48,000 miles

On Sept 16th, 2026 my wife was operating the vehicle under normal, routine driving conditions. While she was completely stopped at a stop sign the vehicle spontaneously caught fire. Description of the Issue and Damage: 1. There was no collision, impact, or external trauma prior to the fire. 2. There were no check engine lights, overheating warnings, or malfunction indicators on the dashboard leading up to this event. 3. The vehicle has been properly maintained and unmodified. 4. The fire originated spontaneously within the engine compartment. As documented in the attached photographs, the thermal event was heavily concentrated on the passenger side of the engine bay. 5. The fire escalated rapidly, resulting in the total destruction of the engine bay, the melting of the passenger-side front fascia and alloy wheel, the destruction of the structural fender, and severe thermal damage to the hood and lower windshield area. 6. My wife was thankfully able to immediately evacuate the vehicle before the cabin was engulfed, escaping physical injury, but she was placed in extreme danger due to this sudden defect. 7. The local Fire Department responded to the scene and extinguished the fire.

UNKNOWN cause. while driving approximately 45–55 mph, the vehicle experienced a sudden and unexpected braking event and engine shut down. •The vehicle automatically came to an abrupt, complete stop. •The engine shut off and then immediately restarted automatically. •A “Service Rear Pads” warning appeared after the vehicle auto-restarted. The vehicle did not gradually slow down; it suddenly and forcefully braked to a complete stop and shut down completely. This was a serious and potentially dangerous safety event as an unexpected stop/shut down event at 45–55 mph could have created a significant risk of collision. We contacted the BMW service center and scheduled a diagnostic appointment for June 22. During the June service visit, the dealership performed: diagnostics, rear brakes and rotors replacement, A/C recharge, tire rotation and balance, and oil change/service. Following the June service, we began experiencing new and intermittent symptoms that had not been present before, including: Ticking, metal clanking, new road/tire noise, Changes in vehicle dynamics and overall driving feel, other intermittent noises. On July 21, we contacted BMW to report the new intermittent noises and changes following the June service and requested an appointment to have these concerns evaluated. An appointment was scheduled for July 24. The July MPI identified several concerns that differed substantially from the June MPI, including: Rear differential leak, worn motor mounts, low battery concerns, & uneven tire wear and cracking. We also observed a permanent brake-pad imprint on a new rotor. These discrepancies raised additional questions and we were told by the SM that the technician had “missed” them in June, even though he documented as good. We refused to accept the X3 back for now d/t safety concerns, and we notified BMW of North America for investigation. The cause for the critical shut down event remains unknown. How can Flow BMW assure it's safe to drive?

The contact owns a 2019 BMW X3. While the vehicle was at an independent mechanic for maintenance, the technician discovered an active coolant leak coming from the coolant expansion tank. The mechanic stated that the leak was caused by excessive system pressure stressing the factory plastic tank. The mechanic informed the contact that if the issue was not resolved, the failure might become a major coolant leak into the engine, and the engine would need to be replaced. The vehicle was not repaired because the leak was coming from several areas. The contact stated that all the plastic parts need to be replaced with metallic parts. The vehicle was towed to the dealer but was not yet diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 69,000.

I was driving in my bmw x3 going about 35 miles an hour and hit a small pothole next thing I know is I got a flat tire when I pulled over the perch plate on the strut had slipped down and hit the tire causing it to blow out and now I'm stuck having to replace the entire strut assembly

**Description of Incident** On **July 25, 2026**, I parked my 2019 BMW X3 xDrive30i in a parking lot and turned the engine off. The vehicle was shifted into Park, locked, and I walked into a nearby store. At approximately 6:41 p.m., I received the update on my phone confirming that my vehicle had been locked. I remained inside the store for approximately six minutes. My purchase transaction was completed at approximately 6:47 p.m., at which time I immediately exited the store. When I returned to the parking lot, I found my vehicle fully engulfed in flames, not merely smoking. The fire had developed rapidly during the brief period the vehicle was parked and unattended. Prior to parking the vehicle, it had been operating normally. There were no warning lights illuminated on the instrument panel, including no check engine light, no engine overheating warning, no temperature warnings, and no other indications of a mechanical or electrical problem. The vehicle was not overdue for scheduled maintenance, and I had no reason to believe there was any issue that would place the vehicle at risk of catching fire. The vehicle was completely destroyed by the fire, which also spread to nearby parked vehicles. Based on the absence of any warning signs and the fact that the fire occurred while the vehicle was parked with the engine turned off for only a few minutes, I am requesting that this incident be investigated to determine whether it may have resulted from a vehicle defect.

I bought my 2019 BMW X3 late 2025 before Christmas. The Carfax was fine and there were no open recalls on the vehicle. The vehicle had been serviced regularly at BMW facilities. Our family mechanic looked at the vehicle before I bought it and performed some basic diagnostics. The vehicle appeared fine. There were no error codes and all of the fluids were topped off. I don't know if the issues with the coolant were there before I purchased the vehicle or if they happened afterwards. There were no warning lights and everything looked good. This car is garage kept and is used a couple of times a week. I did my research on the internet and took my car in for an oil change at a highly-rated independent auto repair facility that specializes in European vehicles and are famous for providing dealership-level expertise, ASE-certified with factory trained technicians from Germany. On March 5th, 2026, when I went to pick up my car, they told me the bad news that is a well known manufacturer defect within the industry regarding these vehicles. They used plastic components in the engine compartment and in the cooling system, which makes the vehicles malfunction. From their report, with pictures, they state the following repairs need to be made, "During the vehicle inspection noticed active coolant leaks are present from multiple locations. The radiator plastic tank actively leaking coolant. The water pump change over valve leaking coolant. The turbocharger coolant line has a coolant crud build up . Oil filter housing and coolant flange on the cylinder block are discolored. For proper cooling system repair recommend complete update of the cooling system. Both balance shaft end caps leaking oil. Recommend replacement during cooling system update." They quoted me $8,914.86 for this repair. That's over HALF the value of the vehicle. They said the entire system needs to be replaced because ALL of the plastic parts in Florida's hot sun will fail. Sudden coolant failures in FL = DEATH.

I am submitting this complaint regarding a serious mechanical and safety issue involving my 2019 BMW X3. On or around January 21, 2024, while driving from my home, a warning signal suddenly appeared on my dashboard related to the vehicle’s cooling system/engine. Due to safety concerns, I pulled into a nearby Wawa parking lot, which was the safest available place to stop at the time. I turned the vehicle off and waited approximately 15 minutes before carefully driving the vehicle back home. After inspection and diagnosis, I was informed that the vehicle required extensive repairs, including an engine replacement and cooling system repairs. At the time the coolant warning appeared, the replacement engine reportedly had approximately 59 miles on it. I believe a sudden engine or cooling system malfunction while operating a vehicle presents a serious safety concern for drivers, passengers, and others on the roadway. In addition, I experienced issues involving the shark fin antenna on the vehicle, which I understand may be connected to broader complaints involving BMW vehicles. I am requesting that NHTSA review this matter to determine whether these issues may indicate a broader defect or safety-related concern affecting other consumers. I am willing to provide supporting documentation including repair invoices, dealership records, photographs, and any additional information requested. Thank you for your attention to this matter and for your commitment to vehicle safety.

While driving our BMW 2019 X3 on the highway, other drivers honked to get my attention that our vehicle's rear hatch was partially open. When we came to a stop light, I had my son riding in the passenger seat press the hatch button on the key fob to close the hatch. Instead this fully opened the back hatch. We continued pressing the fob button in an attempt to get the hatch to close without having to exit the vehicle. Rather than exit the vechicle in the middle of the roadway, we drove about 50 yards until we could pull over safely. A motorcyclist had been following us, and came up behind and communicated that he wanted to press the button to close the hatch. After I gave my consent, he pressed the close button and the hatch closed and latched. My husband has previously had incidents where after parking the BMW, he finds the back hatch open. He's also researched online this is apparently an issue. Reference: [XXX] NHTSA claim XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My SOS system has failed due to tsp/atm module defect from faulty shark fin component. My vehicle is off line and im unable to receive emergency services in case of an emergent situation.

Rear caliper locking up when in reverse. Knocking noise and crunching sound.

My 2019 BMW X3 equipped with a B46 engine developed a significant coolant leak at approximately 80,000 miles. The vehicle displayed a low coolant warning, and coolant was visibly leaking underneath the vehicle. Around the same time, I began noticing excessive white exhaust/steam during cold starts and, for the first time since owning the vehicle, had to add engine oil between scheduled oil changes. The vehicle is currently undergoing inspection by an independent repair facility. Preliminary findings indicate concerns involving premature failure of critical plastic cooling system and/or oil filter housing components. Based on my research, these failures appear consistent with widespread complaints involving BMW B46/B48 engine cooling system and oil filter housing defects. I am concerned this defect could lead to sudden coolant loss, overheating, engine failure, or unsafe driving conditions. Prior to the coolant warning appearing, there were no significant alerts indicating a major or imminent cooling system failure. The apparent failure of critical plastic engine cooling components under normal driving conditions raises serious concerns regarding the durability and safety of these parts. I have photographs documenting the coolant leak, as well as detailed notes and diagnostic information from the repair facility, available upon request. The vehicle is available for inspection.

Our 2019 BMW X3 M40i shows "EMERGENCY CALL SYSTEM MALFUNCTION" which means the "SOS" system, which is crucial for post-collision response, fails. Erhardt BMW in Bloomfield Hills, Michigan confirmed water leakage due to defective sealing around the roof-mounted shark fin antenna damaged the Telematics Control Box (TCB) and now requires replacement. The estimated cost is $3,600. Some quick research revealed this to be a repeated problem with my vehicle. BMW has acknowledged it as a defect in 2017-2023 model year BMW M440i, M550i, X1, X3, X4, X5, X6, X7, 330, 340i and 750i vehicles and fix it at no cost, but only for citizens of [XXX] , as reported by [XXX] of [XXX] .

I'm reporting a safety issue with BMW vehicles equipped with the B58 engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drive train malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

Main dashboard display is partially blocked by a message stating “emergency call system malfunction.” Apparently the roof mounted antenna’s seal fails and allows water into the electronics for the emergency call system. Upon failure, it also stops the Bluetooth microphone for the cell phone to stop working. The dealer quoted the repair at $3,200. Judging from a google search, this is a common problem among this generation of BMW vehicles.

The vehicle's Telematics Control Box (TCB), located beneath the roof-mounted shark fin antenna, failed due to water intrusion and internal corrosion. The failure produced the following fault codes confirmed by BMW of Norwood, MA: B7F341 (backup battery hardware defective), B7F33C (internal ECU error), and B7F327 (microphone short circuit to ground), along with cascading faults across multiple other vehicle modules. Symptoms included a persistent 'Emergency Call System Malfunction' warning on the instrument cluster, loss of GPS/navigation accuracy, and loss of odometer display. The shark fin antenna base seal — a foam tape and adhesive system — had likely deteriorated after approximately 6-7 years of service, consistent with a pattern of failures reported by numerous other owners of 2017-2023 BMW X1, X3, X4, X5, X6, X7, M440i, M550i, 330, 340i, and 750i vehicles. BMW dealer quoted $3,300 for repair. An independent BMW specialist quoted $3,500. BMW North America declined to cover the repair as the vehicle is out of warranty, despite acknowledging the issue as known. This failure mode is the subject of active class action litigation (Craft v. BMW of North America LLC, Case No. 1:24-cv-06826, U.S. District Court for the District of New Jersey) and an ongoing investigation by Sauder Schelkopf LLC on behalf of affected owners. SAFETY CONCERN: The failure disables the Intelligent Emergency Call system, which automatically contacts emergency services in the event of a serious accident. Additionally, the persistent warning obscures the instrument cluster including the odometer display, impairing normal vehicle operation. Water intrusion reaching vehicle electronics represents a broader safety risk if it propagates to safety-critical modules. ACTION REQUESTED: Formal investigation into the adequacy of the shark fin antenna sealing design across affected model years, and consideration of a recall or extended warranty to cover TCB replacement costs for affected owners.

I am reporting a water intrusion issue in my 2019 BMW X3 involving both the roof-mounted “shark fin” antenna and the sunroof. Water enters the vehicle during normal rain conditions and has caused failure of the emergency call (SOS) system. This presents a serious safety concern, as the emergency communication system may not function in the event of a crash or emergency. Water intrusion also creates a risk of electrical damage and potential malfunction of critical vehicle systems while driving. The vehicle has been properly maintained, and this issue appears to be related to known defects involving water leaks from roof components in BMW vehicles. The total repair cost to address these issues is $4,650.

While driving down the highway at about 60 mph, the vehicle made a loud noise like a gunshot, and the sunroof exploded. Fragments of glass fell from the sunroof onto the backseat and floor board and large chunks of glass fell after. There was not any indication that the sunroof was damaged prior to failure and there were no other cars around that could have caused a rock or other debris to fly up and hit the sunroof. Fragments of glass could have injured the driver and the noise startled the driver and could have caused a wreck.

PHANTOM BRAKING ISSUE - Twice now while driving 50-55 MPH on clear roads the brakes slammed on without cause - COMPLETE SHUTDOWN - While going thru a restaurant drive thru - the car completely shut down and would not move forward - I had to back up in order to get out of drive thru - thankfully no one was behind me.

My 2019 BMW X3 (G01 chassis) displays a persistent "Emergency Call System Malfunction" warning on the instrument cluster that cannot be dismissed or reset by the owner. The warning appears every time the vehicle is started and remains on the dashboard throughout operation. This is a known defect caused by failure of the Telematics Communication Box (TCB) module, which is commonly triggered by water intrusion through a defective seal on the roof-mounted shark fin antenna housing. BMW has acknowledged this issue through Technical Service Bulletin SIB B65 12 22 (Roof-Mounted Antenna Housing Seal Not Adhering), yet has not issued a recall or offered a no-cost repair to affected owners. This defect presents the following safety concerns: 1. The persistent, non-dismissible warning light desensitizes the driver to critical dashboard warnings, undermining the purpose of the vehicle's warning system. When drivers are conditioned to ignore a permanent warning, they are more likely to overlook new, actionable safety alerts. 2. The emergency call (eCall) system itself is rendered non-functional, meaning the vehicle will not automatically contact emergency services in the event of a serious collision where the driver is incapacitated. 3. The warning creates a visual distraction on the instrument cluster during driving. BMW's only offered remedy is full replacement of the TCB module at a cost of 1,500â“2,500 to the owner, despite this being a manufacturing defect (faulty antenna seal adhesive) and not a wear item. The defective component is located under the headliner and is not accessible for owner maintenance. This issue is widespread across 2017â“2023 BMW models equipped with the shark fin antenna, including the X3, X4, X5, X6, X7, 3 Series, and 5 Series. A class action lawsuit has been filed against BMW of North America regarding this defect. Numerous complaints have been submitted to NHTSA and documented extensively on BMW owner forums. I am requesting that NHTSA

I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

Beginning in July–August 2025, my 2019 BMW X3 (VIN [XXX] ) began experiencing multiple safety‑critical system failures affecting federally regulated components. The rearview camera intermittently failed to activate and later stopped functioning entirely, resulting in loss of rear visibility required under FMVSS 111. The Emergency Call (eCall) system displayed repeated malfunction warnings, indicating loss of automatic crash notification capability. The vehicle also displayed “Driver Assistance Restricted,” “Collision Warning Malfunction,” and pedestrian detection failure messages, showing that forward collision warning and related ADAS functions were not operating properly. During the same period, the telematics control unit (TCU) lost functionality. This caused loss of ConnectedDrive services, backend communication, remote diagnostics, remote status reporting, and safety‑related over‑the‑air updates. These failures match known BMW defect patterns involving water intrusion into the antenna/telematics module and backend provisioning issues. I submitted a detailed written escalation to BMW of North America. BMW issued two brief responses on February 11–12, 2026 that did not address any of the safety issues, did not provide the engineering basis for excluding my VIN from the applicable recall, and redirected me to a dealer, which has no authority over recall determinations. BMW closed the case without providing any investigation results, defect determination, or technical explanation, contrary to obligations under 49 CFR § 573. These failures materially impair federally regulated safety functions, including rear visibility, collision avoidance, emergency crash notification, and telematics‑based safety communication. The pattern suggests a potential broader defect affecting additional vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On returning to my locked vehicle that had been in the parking ramp for 3 days, I started the car and the display message indicated that my vehicle was completely out of gas and the oil was very low. The vehicle had nearly a full tank of gas when it was parked. The vehicle was towed to the dealership who assessed the vehicle. The service department indicated that the vehicle likely did not sound like it was running because of the idle feature, and as such, I may have thought I shut off the car, but that eventually the idle feature turned off, and the vehicle ran while it was locked until it was out of gas. The service man who sent me a video of my vehicle and described what happened, also showed me another BMW SUV in the hoist next to my vehicle and indicated that same vehicle had the same thing happen as well. BMW replaced the programing/encoding control units software that was original to the vehicle. They indicated that this would improve overall function of the vehicle. The cost of this replacement was $371. This sounds like a design flaw. How can a locked vehicle start back up after a period of time, by itself with no vehicle fob in the vicinity, and run for hours until it is out of gas and the oil is low?

- Frontal Collision warning, Pedestrian warning - yes because safety features were shut off, back up camera doesn't work as well - yes - yes

Starting in July/August 2025, my 2019 BMW X3 (G01) suffered a total failure of multiple safety-critical systems, including the Emergency Call (eCall) system, the rearview camera, and frontal collision/pedestrian alert sensors. These failures were accompanied by a persistent "Emergency Call System Malfunction" warning on the dashboard. BMW Service Information Bulletin SIB 65 12 22 acknowledges a manufacturing defect where the roof-mounted antenna housing seal was "not optimal," leading to water ingress. This water ingress has damaged the Telematics Control Unit (TCB), which manages these safety features. I have contacted BMW North America and local dealerships; however, they have provided a written refusal to repair the damaged internal electronics because the vehicle is out of its original 4-year warranty. Safety Risk: This defect leaves the vehicle in a non-compliant safety state. In the event of a crash, the vehicle cannot automatically notify emergency services (eCall failure). Furthermore, the loss of the rearview camera and collision avoidance systems significantly increases the risk of a crash or injury. BMW is aware of the defect that causes these safety systems to fail but has not issued a safety recall to address the resulting hardware damage. This issue is currently the subject of the Craft v. BMW of North America class-action lawsuit.

At some point in June 2025, between approximately 11 a.m. and 2 p.m., I was driving southbound on the 110 Freeway in Los Angeles, just south of the 134 interchange, at approximately 45 mph. Traffic was light, with no vehicles in front of me and no vehicles attempting to merge into my lane. Without warning, a bright red alert appeared on the dashboard of my 2019 BMW x3 and the vehicle suddenly applied full braking. The position of my arms at that moment caused an injury to my right elbow, which has remained painful since the incident. In January 2026, under nearly identical circumstances, the emergency warning appeared again. This time, the brakes did not engage. In July, I contacted BMW Corporate and service center regarding these incidents. I found their response dismissive, stating that “sometimes that happens.” A service center later informed me that this is a known issue referred to as “phantom braking.” Having experienced this firsthand, I believe this represents a serious safety concern. In addition to my injury, I could easily have been rear-ended at freeway speed. Despite acknowledging the issue, BMW Corporate requested that I sign an indemnity waiver in exchange for covering only the inspection cost. This response feels inappropriate, as their initial focus appeared to be limiting liability rather than addressing a known safety defect. Given that this is reportedly a known issue, I believe an inquiry is warranted into how often this has occurred and whether others have been injured.

Reporting a failure of the engine cooling system on my 2019 BMW X3 that developed over time despite repeated repair attempts and ultimately resulted in complete engine failure. Over the past year, the vehicle has experienced ongoing coolant loss and overheating warnings despite multiple coolant-related repairs. When the problem continued, I brought the vehicle to a BMW dealership, where the service department determined that the engine had suffered internal damage consistent with overheating and advised that a full engine replacement was required. These issues occurred during normal driving and created unsafe conditions, including the risk of sudden loss of power or breakdown in traffic. Based on my experience and the repeated nature of the failures despite proper maintenance, it appears that coolant and overheating issues may be persistent in this vehicle model rather than isolated to a single component, and I am concerned that other owners may be experiencing similar safety-related defects. A investigation into this is warranted.

I am reporting repeated coolant system failures and overheating on my 2019 BMW X3 . I have had 4 coolant-related repairs in under 3 years, including the coolant reservoir boiling after service. Most recently, the problem recurred despite prior repairs. This is a Certified Pre-Owned vehicle with warranty history, and I believe this is a systemic engine/cooling defect that poses a risk of engine failure or fire. Other owners may be affected. A recall or investigation is warranted.

Shark Fin cover knocked of roof while washing at car wash. Dealer was notified and referred me to an auto body shop. I paid for the replacement repair. Dealer never notified me about the loose shark fin problems (water leaks) that are currently a problem with is model (X-3 xdrive30i 2019). A constant hissing noise is heard over the speaker system since the incident occurred. This is not a safety issue. a recall should be issued for the loose leaking fin problem.

2019 BMW X3 with operable sunroof. Significant leakage occurred in front and rear of car risking electrical failure and therefore accident. Dealer denies that this is a problem and Bmw takes no responsibility for what is a hidden defect of the drainage system for the sunroof. Hundreds of individuals have the same exact problem. Hundreds are automatically denied any assistance or responsibility by dealer or manufacture. In a prior claim, it appears that Bmw lost and was found guilty of concealment of a manufacturers defect and was instructed to pay $500 million to plaintiff. Examination of law firms indicate that this significant problem affecting hundreds perhaps thousands of Bmw x-3 has not been registered as a significant complaint, notwithstanding the fact that they have already been in court and been found guilty. Please contact me 804-241-2773 Cell. Or rgrossberg@comcast.net. Examination of owner handbook produced by Bmw informs owner that rails and drains for sunroof must be cleaned. But they indicate that problems with this issue are not covered by the warranty. This needs to be verified. Anecdotal Reports indicate that hundreds of complaints have been received. Bmw is denying any responsibility. Conversation with attorneys indicate this is a habitual problem with Bmw. In this case, it’s a manufacturers defect, on disclosed, causes damage, all problems are denied by manufacturer. Consider this a formal submission of a complaint and a violation of variety of rules and laws covering local, state, and federal jurisdiction Richard grossberg 405 Westham Parkway, Richmond, VA 23229

I am reporting a manufacturing defect on BMW vehicles, specifically the 2019 BMW X3 with fewer than 40k miles. According to a vehicle inspection conducted at a BMW dealership on Saturday November 22, 2025, the motor mounts are collapsed. Potential risks are excessive engine vibrations that could cause loss of control while driving, to engine components to fall off the ground while driving. It’s dubious that BMW dealers “discovered “ this issue after the vehicle warranty expired. I request that the matter be investigated and order the manufacturer to extend coverage to a minimum of 120k miles or 6 years from date of service. Please investigate before it’s too late. Thank you.

While driving my BMW X3, the engine suddenly failed after the check-engine light came on, which followed several days of intermittent high-temperature warnings. Coolant levels had been consistently monitored, refilled, and topped up as needed, yet the temperature fluctuations persisted. Upon further inspection, the repair shop determined that coolant had been leaking internally into the engine due to a cooling system failure, causing overheating and warping of internal components. This created a serious safety hazard, as the vehicle began losing power while in motion, leaving me unable to safely accelerate or maintain speed in traffic and increasing the risk of a collision and a potential fire. This is a serious matter and BMW should assume responsibility for this. I bought the car assuming it was reliable but having to endure this cost out of pocket for an engineering failure is not okay.

The emergency call system on the vehicle has failed and I am getting an error message. The service center at the dealership informed me that water ingress into the shark fin that houses the system caused the system to short and fail resulting in the need for a complete replacement of the system at a cost of $3100. BMW has issued a service bulletin (SIB 65 12 22-Roof Mounted Antenna Housing Seal Not Adhering) that states that the seal of the room-mounting antenna housing is separating from the vehicle. This will allow water ingress into the vehicle, possibly damaging components and equipment. With the correction of remove and reseal the roof-mounted antenna housing. During the service call, the technician confirmed this defect caused the issue. I contacted BMW and they refused to completely cover the repair stating it is not a safety issue. I disagree, I purchased the vehicle with advanced safety features. My wife travels with the car to rural areas and this feature is critical in her safety in the event of a crash. I feel BMW should cover the repair and that this issue is a safety concern for those who rely on an advanced safety calling system purchased with the car. In reviewing message boards, this seems to be an issue for many owners of BMW SUVs.

Despite replacing the water pump, coolant expansion tank, hoses, and other related cooling system components, and fully refilling and bleeding the coolant, the issue persisted. Even after these repairs, the engine continued to overheat and show coolant level fluctuations, indicating an underlying problem likely pressure buildup or head gasket failure that was not resolved by replacing standard cooling parts. Dealership has identified further problems and seem like a costly repair that I won’t be able to do out of pocket. BMW needs to address this issue immediately, engine stuttering and loss of sudden power on the high way is not safe!

2019 BMW X3 - Coolant warning has been going on for the last 6 months and I was refilling coolant every time it went off. I even had the car serviced and they refilled the coolant. Then I was driving the car the engine is overheating warning came on I pulled over. It cooled down. Car was fine but said it needed coolant. I added coolant and noticed it was leaking from multiple spots underneath the car. I had the car towed to a certified BMW mechanic. They did a diagnostic test and inspection and I was told the exhilarator water pump, coolant hose, coolant return line and oil filter house among a list of other things need to be replaced. The repair is estimated at $4700.00

My 2019 x3 model has been leaking coolant from multiple places. I have already needed to replace the water pump at my mechanic and now there's an additional coolant leak and the radiator and radiator hoses are affected and may need replacement. My dealer has not reported this issue yet and no recall has been declared for my type of vehicle, but I cannot afford to fix this issue out of pocket and it's a manufacturer issue when making these materials for the car, no fault of the driver. This has now become an issue where my car is constantly leaking coolant and causing potential engine damage.

Turbo coolant lines/ Oil filter housing failed I am reporting failure of the oil filter housing and turbo coolant lines on my 2019 BMW X3. These parts are leaking coolant due to defective plastic components and sealing surfaces, which causes sudden coolant loss and overheating risk while driving. This is a widespread issue affecting many BMW owners and has been documented in forums, service centers, and BMW technical bulletins. The failure poses a safety hazard, including potential engine failure at highway speeds, loss of power, and risk of breakdown or accident. BMW has not issued a recall or warranty extension, and consumers are being forced to pay out of pocket over $3,000 for what appears to be a systemic design flaw in the cooling system.

The radiator hose system has now failed twice due to faulty hoses and connections.

Subject: Rear Differential Mount Failure and Driveshaft Breakage — Sudden Loss of Vehicle Control at Highway Speed Complaint Summary: While driving at highway speed, I experienced a sudden and extremely loud bang from the rear of the vehicle. Immediately afterward, I lost complete control of the rear end, accompanied by violent clanking and grinding noises from the driveline area. The gearbox then stalled, leaving the vehicle disabled in the middle of the highway. Upon inspection, it was determined that a rear differential mounting bolt had sheared, causing the differential to shift violently out of position. This sudden movement resulted in the driveshaft breaking, which further destabilized the vehicle and led to a severe and immediate loss of control. This failure occurred without warning and created an extremely dangerous situation. The sudden loss of drivetrain integrity at highway speed placed both myself and nearby motorists at serious risk of a crash. A component as critical as a differential mount or driveshaft should not fail under normal operating conditions. This incident strongly indicates a serious design or manufacturing defect affecting the vehicle’s powertrain and structural safety. Requested Action: I urge the NHTSA to investigate rear differential mounting and driveshaft failures on this vehicle model. Such failures can lead to catastrophic loss of control, and immediate attention is necessary to prevent future incidents and ensure driver safety.
