2020 Honda Odyssey Complaints

AIR BAGS — Filed 05/04/2026

My SRS light went on without being in an accident. Around the same time I noticed that there was a recall reported (NHTSA Recall Number 26V-227) which states that the vehicle may deploy airbags without cause by going over a pothole etc. I took my vehicle in to the Honda dealership and they confirmed that my SRS ECU needs to be replaced bc it detected an airbag deployment but since it already deployed they will not replace it under the recall. However, the recall states that they need to update the SRS ECU to prevent this exact scenario from happening without proper cause and if it already happened the SRS ECU will need to be replaced. The worst part is, that they cleared the recall through the database for my vehicle but did not actually fix any issues and the SRS system is still not functioning. I already made a complaint with Honda corporation over two months ago but so far they have not provided a resolution.

Multiple sensors malfunctioned. Mechanic read code U3000-49 (Multipurpose camera unit/millimeter wave radar internal electronic failure). There was no collision or damage of any sort that led to this malfunction. The following systems no longer work: Adaptive Cruise control Collision mitigation system Lane keeping Assist Road departure mitigation system Blind spot info system Tire pressure monitor system Transmission system All of these failures started at exactly the same time. This severely compromises the ability to use this vehicle safely as these systems are all designed to prevent various safety hazards.

ELECTRICAL SYSTEM — Filed 07/18/2026

When vehicle is completely stopped at a traffic light there have been numerous occasions in which all electrical components fail and the vehicle turns off and fails to restart. This only occurs when the auto idle start is engaged. A few times I’ve had to completely jump the vehicle. I have replaced the battery and also had the car examined at the dealership. They stated they had previously updated the system, had heard of other instances of the same issue but since it wasn’t under recall and they couldn’t replicate the issue they couldn’t do anything. This has proved to be extremely dangerous because at rest, without being able to restart when the light turns green my family and I are at risk of being severely rear ended at high speeds.

The vehicle is a 2020 Honda Odyssey. A recurring and dangerous safety failure occurs involving the Auto Idle-Stop system. With the system enabled and the vehicle at a complete stop, the engine shuts off as designed. However, upon depressing the brake pedal to resume driving, the engine severely struggles to restart and completely fails. Simultaneously, the vehicle immediately and automatically shifts itself into PARK, and the entire dashboard display illuminates with all available warning icons and messages. This malfunction creates an immediate, high-risk safety hazard. When the incident occurs, I am trapped, locked in PARK, in live traffic lanes, sometimes at busy intersections or during left-hand turns. It is impossible to shift back into drive or quickly restart the engine. I am forced to remain stationary in traffic for multiple minutes until the system allows me to cycle the ignition completely OFF and then back ON to attempt a full restart and shift back into Drive. This leaves my vehicle, my passengers, and other drivers vulnerable to rear-end collisions.
