Volkswagen Tiguan 2021 — Problemas relatados

The high pressure fuel pump has failed within 40,000 miles and now again at 110,000 miles. It causes the vehicle to randomly turn in drive and while idle. It has had oil consumption issues and oil leak issues that constantly occur. The dealer has replaced the high pressure fuel pump under warranty 40,000 miles and has now detected it needs to be replaced again at 110,000 miles. I paid for oil leak repair which was over 5,000 dollars and now I have another oil leak issues with the oil separator.

At 58,218 miles, the engine on this 2021 Volkswagen Tiguan failed after excessive oil consumption progressed to engine knocking. The vehicle was brought to Volkswagen of Orange Park on July 24, 2025, for excessive oil consumption. The dealer performed a second oil-consumption test. During the test, the engine was heard knocking. The dealer removed the oil pan and found excessive metal. Volkswagen replaced the engine under warranty. The repair invoice was dated August 31, 2025. This created a safety concern because an engine failure can cause loss of propulsion or stalling while driving. The dealer confirmed and repaired the condition.

At approximately 53,876 miles, my 2021 Volkswagen Tiguan experienced a severe, premature failure of the Positive Crankcase Ventilation (PCV) valve / oil separator assembly. The failure of this component caused an immediate, dangerous buildup of internal crankcase over-pressurization. Because the excess pressure could not vent safely, it caused a catastrophic domino effect through the engine block, structurally blowing out multiple critical engine gaskets and rubber oil seals. Furthermore, the extreme downward pressure physically cracked the factory-installed composite plastic oil pan, leading to an immediate and rapid engine oil leak. A sudden and rapid loss of engine oil and internal oil pressure while operating a vehicle at highway speeds poses an extreme safety hazard. Had the oil pressure dropped completely while driving with my children in the vehicle, it could have resulted in a sudden engine seizure, sudden loss of motive power, or complete engine failure on a live highway, placing my family and surrounding drivers in imminent danger of a high-speed collision. Volkswagen is aware of this engine design defect, as evidenced by active internal Technical Service Bulletins (TSBs) and a pending federal class-action lawsuit (Reece v. Volkswagen Group of America, Inc.) detailing identical PCV-induced seal and plastic oil pan failures in the exact same model year. Volkswagen's failure to issue a safety recall for this unlisted "lifetime" part forces families to drive under the threat of sudden component blowout and subsequent engine failure. A mandatory safety investigation and recall are required to address this systemic powertrain defect.

2021 Tiguan parking brake comes on without being commanded. There is a fault with the drivers door. I believe the the driver door module or corresponding wiring. The front drivers window toggle switch does not work the toggles switches for the rest of the window work only if the is not an error displayed on the dash. The lock button does not work on the drivers door at all and only works on the rest of the door when an error message is not displayed on the dash. The dash displays the following errors: 1. Driver Door Contact Switch. 2. Start/Stop. 3. Electronic Parking Brake. It also displays Attention: Engine is running. So far the parking brake only comes on(un commanded) when the vehicle is stopped.

Like many others, at 55k miles, our oil separator malfunctioned causing our oil pan to crack and dump every drop of oil. We had to replace the oil pan and fortunately our mechanic friend figured out it was the new pcv valve malfunction causing too much pressure in the engine. My wife was luckily pulling onto our property when the car essentially shut itself off. When searching for the valve I needed, talking to multiple parts dealers and then a vw tech, none of them are sure why there’s no recall. It happens between 50-60k to THOUSANDS of people now. Then I watched videos on the issue and the mechanics online are all saying the same thing- this should’ve been a recall 2 years ago and are all asking the same question. It’s time VW does what’s right. It’s awfully coincidental that they installed plastic oil pans that would crack and leak under instead pressure, rather than a blowout seals because of the valve failure.

The J949 SOS emergency communication unit failed, disabling vehicle 911 automatic crash notifications and emergency response capabilities.” NHTSA opens defect investigations based on consumer complaint clusters for this exact failure pattern.

Known issues with Tiguan models of overconsumption of motor oil due to faulty engineering of top(head) of engine.

Taking left turns is dangerous. My turn very slowly and Hard press on pedal to turn. Oil consumption is insane. Started at 38k miles, manufacture warranty ended after 4 years. I’m under 52k miles now and have to fill oil about every 1k miles. I’ve had 4 oil changes this year alone. I’m regular about Maintenence. Last oil change was 08/03/26 check oil light came on 8/15 had to add 3.5 quarts 8/26/26 Will keep track of each time I need to add oil and update here. This has been an issue for many Tiguan owners where is the recall???

Noticed the check engine oil light started coming on periodically between oil changes 3-4 years ago, but no external or noticeable oil leaks. Was told by VW multiple times it’s standard for VWs to burn oil. I started having to top off oil much more frequently over the last year, 1 quart per 1000 miles. The check engine oil light would turn on every month at random times while driving. Took my car to a shop; they removed 02 Sensor 1 and borescoped the exhaust system. Found oil leaks from valve seals, leaking into the exhaust manifold. A few weeks later, the check engine light came on for the first time (codes: P24D6 and U3501). Brought car to another shop; they scanned the car and the following codes were found: U350100 (Passive/Sporadic) - Control Module Input Power "A" Circuit Low U041600 (Passive/Sporatic) - Invalid data received from vehicle dynamics control module) P003000 (Passive/Sporatic) - O2 Sensor Heater Control Circuit Bank 1 Sensor 1 U105400 (Passive/Sporadic) - Information electronics 1 control unit No communication P24D600 (Passive/Sporadic) - Evaporative Emission (EVAP) system pressure sensor/switch B circuit range performance. The second shop also stated the valve stem seals needed to be replaced in addition to the Upstream Oxygen sensor and PCV valve. The car was brought to Volkswagen for repair under the extended warranty. Volkswagen confirmed the PCV valve and valve stem seals were bad and needed to be replaced. VW also noted smoke coming from the exhaust. The vehicle has 53k miles on it.

Vehicle abruptly lost power on the highway and limited itself to 3000 RPM. PCV valve failed and oil pan cracked at only 45k vehicle miles.

PCV value/oil leak is a known issue with this specific model of car. The repair I was quited was over $2700 when the car is just out of warranty. There was no oil light indication showing that the oil was low! I only checked everything out because I saw oil in the drive way. The car read zero oil on the dip stick. I added 4 quarts and finallt started to get into operating range. My wife drives this car and could have been in a major accident if it hadn't been noticed.

My name is [XXX], and I am writing today to express my complete frustration mentally and financially with a CPO 2021 Volkswagen Tiguan (VIN [XXX]) I purchased XXX. To date my vehicle has been in for service multiple times – countless times for an issue with the infotainment system and driver warning indicators that is still unresolved and again for months waiting on a new engine due to an oil consumption issue that was finally resolved November of 2025 (Case XXX). My recent service visit on XXX was due to a “12 v battery not charging” error message. The vehicle was immediately taken to VW of [XXX] where we were advised it would be 3 weeks before my vehicle would even be looked at (which is atrocious) and not to drive it because further damage would be caused with no alternative solution offered for transportation. I then had the vehicle towed to a repair shop where I was advised the alternator “fried a 400-amp fuse and killed the battery, which should not happen, especially on a vehicle that has less than 50,000 miles on the odometer.” I paid $1,605.37 for a new alternator, 400-amp fuse and battery. Completely appalling and disappointing considering I take excellent care of my vehicle and it is supposedly an inspected, certified pre-owned vehicle – that’s a lemon in my opinion! I am seeking reimbursement for this huge expense for a vehicle that should not have these issues! I look forward to a resolve to this urgent complaint.

My Tiguan leaks and burns oil like crazy. Now it has 111k miles on it, but this has been an ongoing issue for the last five years since I've had it. I now have to put a quart of oil in every 100 miles. This is not the fault of me getting an oil change, this is a persistent problem caused by the manufacturing of the car. I have had the engine nearly seize up while driving on the freeway due to low oil from this issue. Please investigate and fix.

Electrical screen fail. Makes backup camera turn black and turns off while using. off and on repeatedly while in use. Very dangerous.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving downhill at an undisclosed speed, the vehicle lost automotive power. The vehicle was coasted into a driveway and restarted. Upon restarting the vehicle, the electronic power control (EPC) warning light and the yellow triangle for the central warning light illuminated. The vehicle was idling roughly and jerking while driving to the dealer. The vehicle was previously serviced at 50,500 miles due to an EPC fault, and dealer replaced an electronic actuator. Additionally, the battery was replaced at 50,500 miles, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 51,960.

The PCV valve does not last past 60k miles. Multiple forums and customers stating this. When the failure shows up as a check engine light symptom it has already caused a major oil leak in the crank shaft that leaks with the car off at about 500ml and is significantly worse while driving- Up to a quart of oil loss from driving 10miles. VW has had issues with the PCv valve design from 2012. I bought a 2012 Passat but it did not leak till well after 200k miles but the code would continuously go on and off.

approximately 1 year after purchase, we started having the oil light come on. Returned to dealer and they stated it was normal. This continued for approximately 4 or 5 more times. A "comprehensive" test/diagnostic was conducted and they said normal consumption but no issues. Moving now in 2026 with 40k and now out of warranty with age of vehicle, we brought it back to Scott Motors and NOW it's an issue with the head. The same common problem that they have known about with all their vehicles in this class with this motor since I believe 2018. They want to split the repair bill 50/50 and then 70/30. I stated I addressed and documented the issue years ago and now since we are out of warranty, now you find it. Please Help.

My 2021 Volkswagen Tiguan is experiencing excessive engine oil consumption. The oil level drops rapidly between oil changes, and I have had to add oil multiple times to prevent engine damage. The low oil warning light has appeared unexpectedly while driving, creating a safety hazard. I am concerned about potential engine failure, stalling, or loss of power at highway speeds. I have reviewed multiple NHTSA complaints from other 2021 Tiguan owners (IDs 11742786, 11741539, 11741067, 11739933) reporting the same oil consumption and low oil pressure issues. This indicates a pattern of defects involving the EA888 2.0 TSI engine. Volkswagen dealerships often claim this is ‘normal,’ but the frequency and severity of oil loss suggest a mechanical defect involving piston rings, PCV system, or internal engine components. This poses a serious safety risk, especially during long distance travel. I am requesting that NHTSA investigate this issue for the 2021 Tiguan model year.

The component that is failing is the Radio. The radio consistently turns off when using it and power cycles itself back on which creates a concern when I am using the phone or the Maps feature. I had the same issue with a 2019 Volkswagen Passat, that I previously owned and I now see that there are known issues with other Volkswagen vehicles for the same thing, but there is no recall on my vehicle. I have spoken to my dealership about it and they advised me that there is not a recall for the issue so I would have to pay for them to take a look at this. There are no warnings such as lamps or anything else prior to the failure happening besides if the radio has sound coming through it, you won’t hear the sound anymore and within 60 seconds it will power cycle down for about a minute and then come back on and have to completely reload. There has been no inspection by the police or manufacturer to my knowledge.

On 03/11/26 Volkswagen pushed an over the air update related for an infotainment System Software Update. Immediately upon completion of the updated the Central caution light (exclamation mark inside of a triangle) was illuminated along with the SOS warning light. This has caused by SOS safety system to not function properly. The dealer charged me $200 to diagnosis a problem VW created and stated the SOS Control Module needs to be replaced. They claim the part is on National back order for the past three months. I have been unsuccessful receiving information regarding the repair of my vehicle. I am concerned the SOS system will not function if it is needed.

Rear view mirror has come detached from the main roof and it's presented that the only option to repair this is a complete windshield replacement. If the mirror is adhered to the windshield, this presents a major design flaw and safety hazard. I should not have to replace an entire windshield to replace just a rearview mirror. Also, because this is requiring me to seek additional services outside of the VW dealership, I would have to drive without a safely secured rear view mirror, presenting a safety hazard.

Tha back up camera system is glitching out. We reset the system but is keeps freezing/blacking out after about 30 seconds. This is known issue with this model of Volkswagen.

Vehicle was just turned on and put into reverse. Dash and infotainment center lights flashed and shut off. Vehicle rolled backwards uncontrollably down a sloped driveway. Steering and brakes were not properly functioning. Vehicle came to a stop when it struck a parked vehicle in its path.

Parking brake violently engaging with every stop

When driving the Front windshield spontaneous cracked. There was a loud cracking noise, prior to the AC and vent being turned on. The crack is formed from the driver side bottom edge of the window shield and across horrizontally three feet towards passenger side same crack ending upwards slightly diagonally. There is NO Evidence of impact, crack line is smooth to touch from the outside windshield. Purchased vehicle as a Certified Pre-Owned. Owned the vehicle less than two years. And only driven the car for less than 5k miles. This is unsafe and deemed to be a design flaw.

Car is burning an excessive amount of oil

Excessive oil consumption. Paid out of pocket and 2 weeks later the same issue. Dealer is aware of this common problem and refuses to do anything. These vehicles have faulty piston rings and PCV valves.

On April 19, 2026, my 2021 VW Tiguan experienced a sudden loud gunshot-like sounding noise and my sunroof exploded. I fortunately had the screen closed, but large pieces of glass fell and were caught by the screen. It endangered me and my 3 children in the car. It was extremely stressful, as I was worried the entire sunroof would collapse on us and I was traveling at a high rate of speed. After pulling to the side of the road, further inspection showed the glass protruding upward. No sign of a rock or anything. There was absolutely no warning. I have filed a claim with insurance and plan to call VW tomorrow.

Wipers randomly start when switch is turned off. Wipers will randomly not start when wipers are turned on. Safety of others is affected due to visibility being obscured due to wipers not turning on. Injuries can occur when wipers randomly start. There was no warning prior to the problem starting.

Oil consumption issues affecting all cars of this make and model

Engine has excessive oil consumption. Low oil indicator light will come on and Engine oil needs to be topped and added about every 2500 miles sometimes more often depending on driving conditions.

Oil consumption issue. The vehicle is experiencing blue / white smoke from tailpipe when starting also lost of oil due to a valve seal issue with engine that requires dealers to remove head and service it

Tiguans have been reporting excessive burning oil consumption- reported this to the dealership and consider this "normal" but how is going through several oil containers to make sure there's enough oil in the car "normal"??? I've never had this issue with any other car- other Tiguan owners have reported this issue and it's over a 6k repair.

Here is a quick description of the issue from our Volkswagon of Huntington service report. We have had this ongoing issue for a few months now. the check engine light will come on. We get it checked, we replace a sensor, and all is good for a day or week. Then we do it again, replacing a different sensor. Now the dealer is saying the oil separator is leaking and requires repairs starting at 8,400 and going up from there as they uncover more. We have always maintained the car properly. From research this appears to be a very known issue with this model car and should be reported and covered by VW. SCANNED VEHICLE AND FOUND FAULTS PRESENT FOR SECONDARY AIR. OBSERVED OIL SEPARATOR LEAKING CUASING UPPER TIMING COVER GASKETS TO BLOW OUT ALLOWING OIL TO ESCAPE. FOUND SECONDARY AIR PORTS IN CYLINDER HEAD CLOGGED TRIGGERING CHECK ENGINE LIGHT. ADVISED TO REPLACE OIL SEPARATOR,CAM SHAFT MAGNETS AND CYLINDER HEAD TO START. APPROX 8480.00 PLUS TAX

After oil changes (always maintained at dealerships) it would require a quart of oil with in 2 days. Random starts will blow smoke out the rear. random sluggish behavior. Dealership confirmed PCV valve is causing a buildup in engine pressure which caused a premature oil pan gasket leak. Without full teardown cannot know full extent of damages caused. (which spills out of the bottom and towards tires.....) dealership and fellow Tiguan owners have all reported the same issue! with a repair cost of $1,000-8,000+. same with alot of other years as well.. The date below that i will list is for when the problem was fully confirmed (89k miles) but has always been an issue told its fine ... really noticed it after (68k miles) when i purchased the vehicle. With how many people are dealing with this it is hard to understand how we dont see an open recall for them..... also dealer said pvc valves are on back order and have been. why should one replace with oem if they won't acknowledge its a faulty part?

Check Engine Light came on and got estimate from Pete Moore VW Dealer in Pensacola, Florida and was told the car needed extensive engine repair which included a new cylinder head part. So we waited to come get the car repaired on 3/5/2026 once we had saved up the money for it. We found out the cylinder head is on a Nationwide back order with NO estimated time to get it fixed properly. The technician who gave us the estimate back in September 2025 failed to mention that the cylinder head has been on a Nationwide back order during that time. I am not the only person dealing with this issue in the USA but feel VW has not provided a fix or estimate time to repair these cars properly causing a safety hazard. This time to wait for a part is unacceptable and feel our cars fall under the Lemon Law.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while his wife was driving slowly in traffic, several unknown warning lights illuminated orange, and the speedometer and RPM went to zero. In addition, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact stated that minutes later, the vehicle returned to function as intended. The contact's wife stated that after several minutes, the lights and indicators returned to normal function. A short while later, the failure reoccurred, and the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle then returned to function as intended. The contact stated that on a separate occasion, the driver’s side door failed to open. While using the key fob, the doors failed to open. The contact's wife tested the door, and the only door that opened was the rear passenger’s side door. The contact's wife opened the driver’s side door manually. The vehicle then failed to start. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. Three hours later, when the contact arrived at the residence, the contact was able to start the vehicle, the doors opened as intended, and the contact was able to drive around the neighborhood. The manufacturer was not notified of the failure. The failure mileage was approximately 29,180.

My fuel system level indicator does not work properly when the tank is below 1/2 full, and the check engine light comes on. It does not correctly deplete, instead leaving me with no gas when it shows it still has gas available. This has left me stranded in various locations as my car runs out of gas, but doesn't show me that until it is completely empty. Most recently, it was on a very busy road in the middle of traffic. The gas gauge went from 1/2 full to empty while I was driving. Upon taking it to the dealer, they said to replace the 1 sensor, which is a very small, simple piece, they have to replace the entire fuel system, which is over $5000 in repairs. My car is only 4 years old and only out of warranty by 6 months. Further research shows this is a common issue with the make and model of my car. Many seem to happen under warranty, but with the age my car is now, many of these warranties will expire, leaving owners to have to pay to fix this outrageous, costly repair.

I am experiencing severe oil consumption and leakage with my 2021 Volkswagen Tiguan. The low oil level light began coming on weekly, and I have had to add oil nearly every week to keep the engine from running dry. Recently, I noticed oil leaking underneath the vehicle and immediately parked it. After parking, the vehicle began leaking oil excessively. The problem appears related to PCV system failure, which has caused multiple oil seals to rupture. After researching online, I found many other Tiguan owners reporting the same issues — including PCV valve failure, cracked oil pans, damaged valve seals, and crankshaft seal failures. My vehicle is no longer under the manufacturer’s warranty, and the dealership has not provided a fix. This defect presents a major safety concern because the engine can suddenly lose oil pressure or seize while driving, leading to sudden loss of power or control, which could cause an accident and potential injury. It appears Volkswagen has been aware of similar issues in other model years, but has not issued a recall or permanent repair for this problem. There is currently a class action lawsuit for the exact same issue for 2022 - 2023 Volkswagen Tiguan but doesn't currently include the 2021 Tiguan that I have. I am requesting that NHTSA investigate these widespread PCV and oil consumption failures in 2021 Volkswagen Tiguan vehicles.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the contact's dad who was following behind the vehicle noticed oil splashing onto the front windshield of his vehicle. The contact's dad then noticed while the contact was driving uphill, oil was splashing out of the oil pan. In addition, the contact's dad noticed smoke coming out of the exhaust. The check engine and PCV warning lights were illuminated. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact's dad noticed that the oil pan was completely empty. The vehicle was towed to an independent mechanic, where it was diagnosed with a cracked oil pan. The contact was informed that the oil pan, gasket, and filter needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that while driving at an undisclosed speed, the contact's dad noticed the oil splashing underneath the vehicle again. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact noticed that oil was spilling out onto the road. The oil pan was empty. The vehicle was towed back to the independent mechanic. The independent mechanic contacted the dealer. The independent mechanic was informed that this was a known failure with the vehicle. The independent mechanic was informed that the failure was that the PCV valve had either failed or was clogged. The independent mechanic was informed that the failure normally occurred between 60,000-100,000 miles. The contact was informed that the failure might recur after the repair, however there was no recall for the failure. The vehicle was being repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.
