2025 HONDA ODYSSEY Complaints

Bad starter. When utilizing auto start/stop, the engine would fail to restart at stop. The car would need to be shifted back to park, turned all the way off, and then back on to restart, resulting in a delay - an unsafe practice at an intersection.

Vehicle has auto start/stop and when shutting down at a stop will fail to start back up. Have to shut vehicle down completely and then try to start back up.

Auto Idle Stop system engages (turning the engine off in highway traffic and at a red light or stop sign), the engine occasionally fails to restart on its own. I have to put in park and restart. Almost causing accident started when van had 25k now I have 46k on the odometer and Honda said no longer covered.

-Engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. -This issue presents a significant safety hazard for my two small children and me. On multiple occasions, we have been unable to move due to severe traffic congestion, leaving us vulnerable to aggressive and hostile behavior from other drivers. The resulting situation is both stressful and unsafe, particularly when traveling with young children. -Issue has happened several times -No warning lamps, messages or other symptoms of the problem prior to the failure -Reported the issue to the dealership as the vehicle is still under warranty. Per service technician, there is not alarms or issues with the vehicle. Nothing is being done by Honda to address this issue. Please help

The vehicle’s auto stop-start randomly does not start the engine when releasing the brake. The vehicle is temporarily disabled on the roadway and it puts itself into Park. The vehicle requires intervention to restart the engine and the delay takes several seconds and poses a safety risk by blocking the roadway.

Engine start/stop feature is not working properly and it nearly caused a few accidents. I am getting rid of this car and going to purchase a Toyota Sienna. Android Auto doesn't work either which is a known issue as well and it is a basic safety feature to keep driver's attention on the road and not on their phones.

Idle Stop issue- We were at a stop light and the engine idle stopped. When the light turned green and the foot was taken off the brake, the engine did not turn back on. We had to turn hazards on and turn van completely off. We tried several times to restart the vehicle and the engine did not respond. We finally got it to turn on a couple minutes later but the engine sounded as if it was struggling to turn on.

While the van is at a complete stop at the intersection it shuts off and behaves as if it needs to be restarted. A message appears instructing me to press the brake and push the start button to start the van. I took it to Honda, but they were unable to find the issue. They replaced the battery to see if that would fix the problem, but about a month later, it happened again.

Auto Idle Stop (AIS) system fail to restart: The engine fails to restart on its own after a complete stop at a traffic light or intersection with the Auto Start/Stop function engaged, putting the driver in dangerous and panic situation.

On three separate occasions — May 17, May 20, and May 29, 2026 — the vehicle's Automatic Emergency Braking (AEB) / Collision Mitigation Braking System activated without cause while traveling at highway speed (one of these occasions was on an interstate). On each occasion, no vehicles, pedestrians, or obstructions were present ahead of or around the vehicle. The road was clear. The activation produced a large bright yellow dash notification and the vehicle's brakes activated. Minor children were passengers in the vehicle during these events. The vehicle has an active Florida Lemon Law case with multiple prior documented electrical nonconformities. When I attempted to schedule yet another service appointment to have THIS defect diagnosed, the dealer, who sold me the vehicle, refused to service the vehicle due to the pending lemon law status and directed me to contact Honda Corporate. When I asked the dealer to provide their refusal and the requirement for Corporate authorization in writing, they declined to do so. Honda Corporate has not responded in over 72 hours. Photo and video evidence of other nonconformities is available.
