2020 HONDA ODYSSEY Complaints

I stopped at a red light and then my car just stopped. It seemed the car wasn’t able to start up the engine from the idle mode. I had to restart the car at the intersection with a truck behind me and with 3 kids under the age of [XXX] on the car with me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After a heavy rainstorm, the power tailgate motor stopped opening or closing the tailgate.

The sliding door will not open, either manually or automatically. This is a huge safety problem since my children cannot get in or out of the vehicle quickly in an emergency. What should I do if this happens on both doors, I will not be able to open either sliding door.

The contact's daughter owns a 2020 Honda Odyssey. The contact stated that while his daughter was driving at an undisclosed speed, several unknown warning lights illuminated. The contact attempted to inspect the vehicle but could not determine the cause of the failure. The vehicle was taken to a dealer, where the contact was informed by the technician that the failure might be from the wiring connected to the rearview camera. The contact declined to pay for a diagnostic test. The contact attempted to repair and realign the rearview camera; however, the part needed to realign the camera could not be purchased and could only be serviced at a Honda dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

Receiving ACC, lane keep assist, front collision , auto high beam errors on the instrument screen. None of the safety features work. Cruise control does not work.

Multiple Honda Sensing safety systems (collision mitigation, lane keeping, road departure, adaptive cruise, and auto high-beam) disabled suddenly on 2020 Honda Odyssey EX-L around 76,000 mi. Dealer and two independent diagnostics confirmed DTC U3000-49, internal electronic failure of the forward recognition camera. The fault disables all automatic braking and lane-keeping functions. Battery voltage and calibration verified OK; component failure is internal. Honda quoted ~$2,000 repair. This is a significant safety risk since all advertised crash-avoidance functions stop working.

the front monocular camera is defective causing the safety features (adaptive cruise control, collision warning, lane shift warning, auto brights, auto braking) to not function at all. This seems to be a known issue with many honda owners. The warnings show every time I start the van. This issue has been verified and the repair is costly.

After purchasing my 2020 Honda Odyssey EX-L in July 2025 (had approximately 58,000 miles), in January 2026 (current mileage approximately 66,000 miles), it suddenly displayed multiple indicators on the dash, including 'ACC', 'LKAS', 'Brake System', 'Auto High Beam Problem', and 'Collision Mitigation'. My local mechanic indicated the cause was the collision radar system, but it needed to be calibrated at a Honda dealership. My local Honda dealership indicated the problem code as 'U3000-49 Internal Camera Malfunction', necessitating that the multi-purpose camera be replaced. The total repair cost was $2,104.99. Online research shows that this is a common issue with this model year. If the cause is due to a camera malfunction or disrepair, and it impacts the safety of myself and others in the vehicle, why is this not considered a valid reason for a recall? I shouldn't be responsible for a costly repair that didn't result from any mechanical issue or mistreatment on my part. Because of the safety implications, this should be a Honda recall, and I should be reimbursed for the repair cost.

Went to pull into parking lot, ADAS system starting going crazy. Throws transmission malfunction error. Headlights won’t work - they turn on and off or go extremely dim. Van keeps jerking and losing power. Code reader showed U3000-49 electronic failure. Van drove normal, no issues until this code popped up. Issue started 01/08/2026.

The Multipurpose Camera Unit has failed resulting in loss of Adaptive cruise control, lane keep assist, Automatic braking and other features related to the MCU. There are approximately 6 warnings when starting the car of features not working, and 3 lights that remain lit on the dash including "Brake System". This is the second time this issue has arise. The first time was replaced by the dealer under warranty.
