Honda Odyssey 2018 — Reported problems

The front camera that controls lane keep assist, adaptive cruise control, collision warning, auto high beam, lane departure failed so none of these features work. The component has been replaced by a Honda service center. I don’t believe the failed component is available to inspect.

The vehicle was stalled on highway local about seven times. My car got stranded and almost got into serious accidents. This happened multiple times and Honda couldn’t fix it. I spent $9000 and couldn’t find the problem. Honda changed fuel injectors, pump, regulator, high pressure. But the car is still stranded on highway which is very dangerous

Camera/Radar behind the rearview mirror failed. This triggered the following alerts to populate. Forward collision alert, auto high beams, lane departure, active cruise control (active and passive both failed to work), brake system, transmission system, lane keep assist failure. The gear indicator would flash when the transmission system error came on. Van has ~76k miles on it. ~$119 for diagnosis, ~$1400 for the part, ~$300 for the calibration and several additional hundred in labor. This is a known issue with the 5th generation Honda Odysseys. Honda won't do anything about it. It was up to 8 error messages on the dash at one point.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving out of the driveway, the rear passenger’s side power sliding door unexpectedly opened, with a message displayed that the rear door was opened. The contact stated that there was a failure with the automatic operation of the rear sliding door. The vehicle was taken to the dealer and DTC: B2087 was retrieved. The contact was informed that the rear latch assembly had failed and needed to be replaced. The vehicle was not repaired. The contact was informed by the dealer that the repair might not fix the vehicle and could cause additional issues. The contact stated that the failure was associated with NHTSA Campaign Number: 18V795000 (Latches/Locks/Linkages). The manufacturer was made aware of the failure by telephone. The failure mileage was approximately 113,987.

I own a 2018 Honda Odyssey Elite. On October 5, 2026, at 120,007 miles, an authorized Honda dealership diagnosed the vehicle with DTC U3000-49, Multipurpose Camera Internal Failure. The Honda technician cleared the DTC, but it returned shortly afterward. The technician inspected the camera and connector for poor connections or damage and documented that none were found. The dealership determined that the multipurpose camera needs to be replaced and reprogrammed. I was quoted $2,350 plus tax for the repair. The failure causes multiple Honda Sensing safety and driver-assistance systems to become unavailable and produces multiple dashboard warnings, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and related safety-system warnings. I have video documenting these warnings following the dealership diagnosis. My safety concern is that an internal failure of a single multipurpose camera can simultaneously disable multiple collision-avoidance, lane-assistance, and driver-assistance systems. I am reporting this failure so NHTSA has a record of the U3000-49 failure on my 2018 Honda Odyssey and can determine whether this represents a broader safety defect affecting these vehicles. The vehicle has not yet been repaired.

The contact owned a 2018 Honda Odyssey. The contact stated that water was seeping into the trunk during inclement weather or while washing the vehicle. The contact stated that several warning lights remained illuminated, and the cruise control, blind spot detection, lane departure warning, and powered tailgate failed to function as intended. The vehicle was taken to a dealer where it was diagnosed, and the contact was informed that the metal on the power tailgate needed to be welded to stop the leak, and the dash camera and computer needed to be replaced due to the water damage. The vehicle was repaired; however, water was still entering the vehicle during inclement weather or while washing the vehicle. The manufacturer was notified of the failure. The failure mileage was 88,000.

-multiple messages/lights on dashboard determined by dealer to be due to forward looking camera, which disables Hondas Sensing safety suite. Available for inspection upon request. -safety of myself/family and others put at risk due to distracting messages/lights on dashboard, which can also conceal additional issues not associated with forward camera. Safety features are disabled when the camera does not work properly, specifically lane assist, adaptive cruise control, collision mitigation , road departure mitigation, auto high beams. -problem has been confirmed by dealer: DTC U3000-49 -yes, inspected by manufacturer/dealership -issue appeared randomly approximately a month ago with no other warning signs

Repeatedly, often several times a day, the front seatbelts become unlatched. They become unlatched without any warning either immediately after fastening them, or while driving

The vehicle doors have given issues where they open when attempting to close. The doors will start closing and then reopen or don’t close at all. We’ve had this van for about a year and started having this issue early on. Upon searching online, it was discovered that are many instances where door issues have occurred and a site found to further support this but my VIN was not listed even though the same issue occurs. https://www.consumerreports.org/car-recalls-defects/honda-odyssey-minivan-recalled-over-problem-with-sliding-doors/#:~:text=Honda%20is%20recalling%20107%2C000%20of%20its%202018%20and%202019%20Odyssey%20minivans%20because%20its%20power%20sliding%20doors%20may%20not%20latch%20properly%2C%20raising%20the%20possibility%20that%20they%20could%20open%20while%20the%20vehicle%20is%20in%20motion%2C%20according%20to%20the%20National%20Highway%20Traffic%20Safety%20Administration.%20According%20to%20Honda%2C%20some%20components%20in%20the%20power%20sliding%20door%27s%20rear%20latch%20assembly%20are%20prone%20to%20sticking%2C%20which%20can%20stop%20the%20front%20and%20rear%20latches%20from%20securely%20connecting.%20This%20problem%20affects%20the%20left%20and%20right%20power%20sliding%20doors%2C%20Honda%20says.

The front camera has failed so all of my forward driving safety features no longer work such as lane keep assist, adaptive cruise control and collision mitigation. Every time I turn on the engine I have multiple warning lights that appear every time that have to manually acknowledge to clear them from my dashboard.

The Fuel Injectors are failing which is causing a safety concern with regards to moving the vehicle. There was a warranty extension on these items that does not go far enough to remedy the issue. The components have been inspected and confirmed by the Burns Honda Dealership in Marlton, NJ. Because the vehicle does not consistently accelerate, it is a safety risk.

2018 Honda Odyssey EX-L, The vehicle consistently has a significant delay in acceleration. This is especially noticeable when starting from a stop or low speed and attempting to make a left turn across traffic. The accelerator pedal is pressed, but the vehicle sometimes provides little or no acceleration for 1 to 2 seconds. The vehicle will then begin accelerating, sometimes abruptly. This has created a safety concern because the vehicle can begin entering an intersection but fail to accelerate as expected, leaving it exposed to approaching traffic. The problem has occurs regularly and has been noticeable for an extended period. There are no intentional actions by the driver that would account for the delayed response. I am aware of two other Honda odysseys doing the exact same thing. One being my neighbor who brought it up themselves and another, an individual at work. My neighbor has the same year and model. The other I am unsure about. This seems to be a consistent and likely widespread issue. The vehicle is a 2018 Honda Odyssey EX-L equipped with the 9-speed automatic transmission. I will be scheduling the vehicle with a Honda dealership and ask the dealership to diagnose this acceleration-delay problem.

Multiple warning lights on. Dealership told me it was code U3000-49 Multipurpose Camera mutimimillmeter wave radar internal electronic failure

Car takes longer to start, difficult to accelerate and stalls. Shaking hard when accelerating at certain speed. There is a p0087 code when autozone scanned it.

crankshaft/rod bearing defect that is causing an audible knocking noise in the engine and located metal shavings in the oil.

1. Component failed: The low-pressure fuel pump failed. The vehicle is currently sitting at my residence and is available for inspection upon request.2. Safety risk: The vehicle stalled completely while driving, causing an immediate loss of propulsion on a public road, creating a severe collision risk.3. Confirmation: The problem has been pulled and confirmed by an independent service center (AutoZone diagnostic scan tool), which pulled a code to replace the fuel pump.4. Inspection: The component has not yet been inspected by the manufacturer, police, or insurance representatives, as the manufacturer is currently refusing to authorize an inspection due to a salvage title.5. Warning lamps/Symptoms: Immediately prior to the stall, a complete cascade of warning lights appeared on the dashboard simultaneously, and the vehicle sputtered aggressively upon attempting to crank and restart.Assessment: This is the identical, textbook physical failure condition of NHTSA Campaign 23V-858 regarding defective factory-installed Denso fuel pumps in 2018 Honda Odysseys. American Honda Corporate is using an automated salvage title database filter as a pretext to deny mandatory federal safety recall remedies on a vehicle with zero structural fuel system damage.

All systems relating to the forward facing camera have failed.

This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving 25 MPH, the audio of the vehicle unexpectedly became inoperable. The failure was a recurring failure. Additionally, there was an abnormal burning odor inside the vehicle. The contact associated the failure with NHTSA Campaign Number: 23V431000 (Back Over Prevention); however, the VIN was not included in the recall. The dealer was contacted and stated that the cost of the repair was not covered because the VIN was not included in the recall. The failure mileage was approximately 90,332.

My vehicle intermittently shifts from normal automatic Drive (D) into S mode without any intentional driver input. I do not touch or activate the steering-wheel paddle shifter when this occurs. Searching on reddit and other forums I see many other drivers have the same issue. The problem appears to happen primarily after coming to a complete stop, such as at a traffic light or stop sign. When I then press the accelerator to proceed, the vehicle may have very little acceleration because it has unexpectedly entered S mode. This has occurred while I was attempting to turn or proceed into traffic and has nearly caused an accident on multiple occasions. The issue is intermittent and cannot be reproduced on demand. However, it has happened multiple times under similar circumstances. I am certain I did not intentionally activate the paddle shifter. I am concerned this may be a safety defect involving the electronic shift control, paddle shifter, transmission controls, sensors, or related software. An unexpected change in transmission mode immediately after stopping can create a dangerous situation because the driver expects normal automatic operation and acceleration when entering an intersection or traffic. I am requesting that NHTSA document this complaint and investigate whether this is a safety-related defect that may affect other vehicles.

Tail gate problems Looks like there are a lot of tailgate problems with the Honda Odyssey, including water leaks that can affect the control module. I replaced the control module, but it looks like there’s a lot of information and research about this issue online.

Rear sliding door failure, doors wouldn't latch properly resulting in opening when driving down the road. Took to dealership for repair. Paid 1633.78 they replaced rear latches 3/31/2026. Rear latches failed to open resulting in one Rear door cable breaking and one that will not open at all 9/1/2026. Neither door opens at this point.

The contact owns a 2018 Honda Odyssey. While the contact's wife was driving at an undisclosed speed, the vehicle drove over a pothole and the driver's- and passenger's-side curtain airbags deployed. The air bags deployment frightened the contact’s wife, and the steering wheel was jerked, and the vehicle crashed into the concrete median. The contact stated that the front driver's side tire was flat. The contact removed the deployed side curtain air bags and replaced the driver's side front wheel. The vehicle was inspected by the insurance company. The vehicle was deemed a total loss. The contact received notification of NHTSA Campaign Number: 26V227000 (Air Bags). The contact stated that the recall notification was received the day after the failure had occurred. The manufacturer was contacted by phone, and a case was filed. The contact was informed that the case was denied. The failure mileage was approximately 135,000.

The contact owns a 2018 Honda Odyssey. The contact stated that the rear liftgate was inoperable and had to be unlocked through the emergency release in the trunk. Additionally, the contact stated that the rear window seal was significantly fractured. A message that the tailgate was inoperable was displayed accompanied by a chime that was heard inside and outside the vehicle while driving. The contact stated that the message was displayed after a rainstorm. Additionally, while the contact's son was using the seat belt, the contact became aware that the passenger’s side third-row seat belt and seat belt retractor housing attached to the roof were wet. The vehicle was taken to a dealer, where it was diagnosed and determined that the tailgate printed circuit board for the locking mechanism was corroded, and the motor had failed. The vehicle was scheduled for the repair. Additionally, the dealer referred the contact to an auto body service center to determine where the water was entering the vehicle. The failure mileage was approximately 60,000.

NHTSA Recall 19V-299 / Honda Campaign Z4J. Sudden gear refusal, shifting malfunctions, and stalling. The premature structural failure of my 10-speed transmission is a direct consequence of the known factory software defect that violently shifts the car into Park while moving.

The vehicle would not accelerate over 40MPH, we took the vehicle into the dealership for what we thought was a failed fuel injector, upon inspection they found metal shavings in the oil and mentioned the engine is not repairable and would need a whole new replacement. We had this vehicle 9 months. Upon investigation there was a known recall that is identical to the issues we are experiencing. The whole engine is failed and we cannot utilize it. It was inspected by the dealership. The check engine light is illuminating, and does not increase in speed. My family and I were unable to drive at a reasonable speed on the highway once it failed.

The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the passenger's side power sliding door unexpectedly opened and failed to latch. The vehicle was not diagnosed or repaired by a dealer or an independent mechanic. The contact associated the failure with NHTSA Campaign Number: 18V795000 (Latches/Locks/Linkages); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 195,000.

COMPONENT THAT FAILED & AVAILABILITY: The vehicle's primary electrical architecture and data communications network (CAN bus) failed during a safety recall service for the SRS ECU and rearview camera. After attempting to complete the recall work, the vehicle is no longer able to start. SAFETY RISK: The manufacturer's federally mandated safety recall remedy compromised the vehicle's critical safety and control infrastructure. This rendered a previously reliable family vehicle entirely inoperable, destroying its ability to communicate, start, or turn on. It poses a systemic safety risk if the corporate recall procedure itself causes severe electronic failures in consumer vehicles. REPRODUCTION & DEALER CONFIRMATION: Yes. The failure was induced directly by Williams Honda ([XXX]) during service on Thursday, XXX. The dealership's Service Manager explicitly confirmed to me that their technicians compromised the electrical architecture while performing the SRS ECU and rearview camera recall work. The vehicle has remained dead at their facility ever since. INSPECTION BY OTHERS: The vehicle has been actively inspected by dealership technicians in coordination with Honda Engineering headquarters. It has not been inspected by police or insurance representatives, as no crash occurred. I have requested an inspection by a Honda Corporate Field Technical Specialist (FTS). WARNING LAMPS & PRIOR SYMPTOMS:NONE. Prior to this appointment, the vehicle was in perfect electrical and mechanical working order. There were absolutely no warning lamps, messages, or symptoms of any starting or electrical problems. The vehicle had just safely completed a seven-hour road trip immediately prior to being dropped off for the recall work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The monocular camera (multipurpose camera secured under the rear view mirror) has failed. This disables the following" Collision Mitigation Braking System (CMBS): Detects obstacles or vehicles ahead and helps brake automatically if a collision seems likely. Forward Collision Warning (FCW): Works with CMBS to send visual and audible alerts if you get too close to a vehicle in front of you. Lane Keeping Assist System (LKAS): Adjusts steering torque to help keep your van centered in a detected lane. Lane Departure Warning (LDW): Alerts you if you drift across detected lane lines without using your turn signal. Road Departure Mitigation (RDM): Applies steering help or braking if you drift off the paved road entirely. Adaptive Cruise Control (ACC): Maintains a safe, set following distance behind a vehicle traveling ahead of you. These systems are helpful in keeping you safe while driving. The problem with camera failing cause these system warnings to populate on the dash. This is distracting. This has been confirmed with independent service center. Has not been inspected by manufacture. Started August 21. quoted $2200 to replace and recalibrate.

The car on a weekly basis or almost every time it is driven. The car jerks when driving at low speeds. This is a safety risk when driving for vehicles in front or behind me, as the car jerks forward. This has been mentioned to the dealer, but they stated a charge of 180 USD will be incurred for diagnoses. If you look at the NHTSA complaints database there are numerous complaints similar to what I am experiencing from other owners stating the same issue of jerkiness on the honda Odessey. I am surprised there is no recall on this. I put the date in down below but it happens almost every time the car is driven.

Forward Collision Warning

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate, requiring the contact to forcefully depress the accelerator pedal to move the vehicle. The contact stated that multiple warning lights unexpectedly illuminated, including the Road Departure Mitigation system, Collision Mitigation Braking System, and Lane Departure Warning system warning lights, and all related safety features failed to operate. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 105,000.

A warning for Power Tailgate Problem keeps coming up. It tried to open multiple times while driving, beeping at us. It wouldn’t open with the buttons at all. We had to manually open and close it. This makes the second time it’s done it. And it always has to do when it rains. Honda knows this is a well known issue with their odyssey’s and it needs recalled. The dealership wants us to pay for a well known issue. We had a friend with the same year odyssey and the same thing happened but their tailgate completely opened a few times while driving.

The passenger side curtain airbags deployed while driving with no prior warning.

My Odyssey randomly began displaying all of the ADAS warning messages: The Brake System indicator light comes on, Forward Collision Warning, Lane Departure Warning, Lane-Keeping Assist, Auto High Beam System error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire ADAS system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.

Faulty transmission. Lags when you start to drive. Constant delay.

The contact owns a 2018 Honda Odyssey with Vredestein Tires, Tire Line: Quatrac Pro Plus, Tire Size: 235/60/R18, DOT Number: 023 45E427 1425. The contact stated that the side wall on the front passenger tire had begun to form bubbles. The tire distributor was notified of the failure, and the tire was replaced however shortly after having the new tire replaced with the front driver's side, and the front drivers side placed on the front passenger side, the contact stated that shortly after upon inspection it was discovered that the tire was shredding and chunking on the shoulder. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The tire was a replacement tire. The vehicle failure mileage was 86,767 the tire failure milage was 3,200

2018 Honda Odyssey Elite I am reporting an unresolved issue stemming from a failed recall remedy for NHTSA Safety Recall 23V-431 (Honda TSB 20-049) regarding the MOST bus fiber-optic network. My vehicle has been taken to an authorized Honda dealership twice to receive the official recall repair (replacing the FAKRA network connectors). Despite these two repair attempts, the network defect continues to escalate.The vehicle experiences sudden, violent, and near-constant loud popping and clicking noises through the audio speakers while driving. This occurs both at random and predictably when driving over bumps. Following the increase in these network pops, the vehicle's Blu-ray player completely failed and stopped working. Furthermore, the central infotainment screen frequently freezes, reboots, and displays an "Audio Connection Lost" error message, which also cuts out the FM radio tuner entirely.Crucially, this fiber-optic network failure recently caused a total loss of the digital instrument cluster and speedometer while driving. While this complete cluster blackout has only occurred one time so far, it presents an unpredictable and dangerous safety hazard, as I am left with no knowledge of my current speed or critical vehicle safety alerts while in motion.The manufacturer’s standard recall remedy of swapping plastic connector clips is ineffective for my vehicle. The recurring failures after two repairs indicate a permanently compromised factory wiring harness or a damaged network module that is continuously dropping the signal. The manufacturer needs to authorize a thorough diagnostic and full harness/module replacement to permanently resolve this safety defect before the instrument cluster fails again.
