2020 HONDA ODYSSEY Complaints

After owning this vehicle for a little over a year without issues, I turned on the vehicle and randomly received the following five (5) error messages: Collision Mitigation System Problem, Lane Keeping Assist Problem (LKAS), Adaptive Cruise Control Problem (ACC), Road Departure Mitigation System Problem, and Auto High-Beam Problem. I realized that other Honda Odyssey owners have mentioned receiving the same error messages, especially around my year (2020). The believe all of the error messages are related to the same component - either faulty wiring, camera system, or install issue. The error messages come on every time I turn on the vehicle now. I live in Texas and the first day it occurred was especially hot - it first occurred in the summer months. It is now December with mild weather and the error messages still occur. It is worrisome because the Collision Mitigation System was among the safety features that contributed to us purchasing the vehicle.

I am writing to report a significant safety issue with my 2020 Honda Odyssey. The Front Assembly Assist Monocular Camera (OEM part 36160-THR-C01-M1) has failed, causing the loss of several critical safety features, including auto high beam, lane departure warning, adaptive cruise control, collision mitigation, and Lane Keeping Assist System (LKAS). The local Honda dealership diagnosed the issue as an internal fault in the camera unit. Through research, I have discovered this failure is not an isolated incident. Numerous reports from other Odyssey owners highlight similar issues with the camera leading to the deactivation of these safety features. For example, discussions on the Honda Odyssey Forum and other online platforms describe widespread failures of front-camera-dependent systems, including lane-keeping and collision avoidance features. These failures compromise vehicle safety, potentially increasing the risk of accidents. The camera’s malfunction disables essential systems designed to enhance driver awareness and prevent collisions, leaving drivers vulnerable in critical situations. I respectfully request that the NHTSA investigate this issue, as the consistency of these reports suggests a systemic problem. A recall or corrective action may be necessary to ensure the safety and reliability of these vehicles. Thank you for your attention to this important matter.

The contact owns a 2020 Honda Odyssey. The contact stated that the back-over prevention camera and cross-traffic monitor were inoperable. The cross-traffic monitor not functioning message was displayed. The vehicle was taken to the local dealer, who confirmed that the vehicle had been repaired under NHTSA Campaign Number: 20V438000 (Back Over Prevention). The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 34,000.

While driving on highway, 3 hours away from home, all of a sudden van slowed down and jerking and shaking with loud grinding movement sound from the van started. No warning sign displayed on the dashboard display screen and no warning alert either. Luckily got out of the exit and parked the van. Van was not going beyond first gear and jerking and shaking and making loud grinding sound. Van was not drivable safely. Towed to the local Honda dealership which was 30 miles away. Dealership checked the Van and diagnosed that the 10 speed Automatic transmission has failed and need a new transmission now. There is no warning sign or error on the dashboard display and any warning alert even after this incident happened. I am very disappointed that such an expensive van has no good warning sing or alert system for transmission failure, even though vehicle has computer to monitor every small thing but no good warning system for most expensive automatic Transmission system. This is total lack of care and failure on the part of manufacturer Honda, which did not put some good warning system on these defective automatic transmissions. These sudden failures can cause catastrophic accidents on the highways and roads. This sudden failure of transmission should have been a recall for defective manufacturing of 10 speed automatic transmission in Honda Odyssey van.

I have less than 35k miles on my car and I have 5 warning that appeared out of no where. My car has never been in an accident and I take care of it. I searched on YouTube and apparently this is very common issue. It cost $3500 to fix and needs to be with a dealer. The 5 warnings are Issue with car 1) Lane keep problem assist, 2)auto-high beam problem, 3) road departure mitigation system, 4)adaptive cruise control, 5) collision mitigation system, The car is 4 years old and should not have this problem but a lot of people who own the same exact model have tge same issue. Honda needs to do a recall and fix it for free

I just started up the car one morning and had multiple sensor warnings. Brought it to the Honda dealership and told it was an internal sensor camera malfunction and wanted $2000+ to fix it. This honestly should be a recall as I’ve had several other Honda owners complaining about the same thing which is a huge safety concern

All of a sudden warnings appear related to Collision Mitigation system Problem Lane Keeping Assist Problem Auto High Beam Problem Adaptive cruise control problem Road departure mitigation problem This is a major issue. I don’t feel safe driving this car with my family. Therefore NHTSA should get Honda to issue a recall for this vehicle given the magnitude and sheer scale of the problem. Below is one of many such forums where people who model years 2018-2020 have the exact same problem. https://www.odyclub.com/threads/lkas-acc-collision-avoidance-auto-high-beam-problem.373456/page-2?nested_view=1&sortby=oldest

There are five warning indicator on the dashboard complaining about Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance. I took the car to the Honda dealership, and they acknowledged that they were due toan internal failure of the multipurpose camera.

The contact owns a 2020 Honda Odyssey. The contact stated that while driving at various speeds, the engine revved high while depressing the accelerator pedal. The contact then received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline), which was linked to the failure; however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The local dealer was contacted several times and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The failure mileage was unknow. Parts distribution disconnect.

Car was operating fine on the way to a game on 11/25/2024. Parked and went inside to watch game. After the game I went to my car and when I cranked it all the warnings below came on. **Auto High Beam problem **ACC problem **Brake System problem **LKAS problem those are the warnings I can remember. I immediately cut the car off and walked around to see if maybe I had been hit while parked cause something told me it could be a camera issue with the LKAS problem ???????. I had not been hit. The car was fine and just as it was when I parked it. I cranked it again and the lights were still on showing problems and stayed on. I took it to the dealership and they said it's the multi-purpose camera malfunction/went out and needs new one.
