2025 HONDA ODYSSEY Complaints

While stopped at a red light or intersection, the vehicle's Auto Idle Stop feature engages and shuts off the engine as designed. However, on multiple occasions, the engine has failed to automatically restart when the brake pedal is released. The vehicle remains stalled and unresponsive in the middle of the intersection or traffic lane, creating a safety risk to myself and other drivers, particularly at busy intersections. In some instances, the vehicle needed to be fully powered off and restarted before it would move again. This is a known and widely reported defect affecting Honda and Acura vehicles with the Auto Idle Stop system, currently under NHTSA Engineering Analysis EA25004. The problem has occurred repeatedly and unpredictably, with no consistent warning beforehand. The vehicle and its Auto Idle Stop system are available for inspection upon request. The problem has not yet been confirmed by a dealer, though I intend to bring it in for diagnosis. There were no warning lamps or messages before the failures occurred; the only symptom was the engine simply not restarting after an automatic idle stop.

I was at the red light and the car wouldn't come out of idle. The battery light came on and the i tried to turn the car off and it just keeps cycling. I had to open the door for the car to cut off and then restart the car. This is the 3rd time this has happened and almost resulted in me and my children being hit.

While at a stop light on a major road, the vehicles auto start stop engaged. Upon the light turning green, I released the brake and vehicle failed to restart. The vehicle put itself into park and flashed a warning message "problem detected....." . I pressed the start button, and at first the vehicle failed to start, making a clicking sound, consistent with a dead battery or starter. I had to press the start button 4 times before the vehicle restarted and I could proceed. I was extremely concerned as I had my wife and three kids in the car, unable to move forward on a major roadway. I have an appointment at the dealer for this Friday.

After driving the vehicle and stoppping for gas or to run a quick errand the van sometimes will not start, or gives difficulty starting. Slow to crank or turn over, sometimes has to be started multiple times before it will restart. It happens after the motor has been running. It never has issues first thing or the first time turning the car on for the day. The issues come once the motor has been run. -took the vehicle in to Honda dealer on 6/8/26 they recharged the battery. -7/9/26 took van into Honda dealer they replaced the battery. 8/15/26 van still having issues starting once engine warm. Dealership said starter is failing and replaced the starter.

Sometimes the engine wouldn't start. Sometimes the engine would be slow to start. Checked battery and nothing wrong with it. Took it to Honda and asked to look into common starter problem. They did say the starter was faulty and replaced it.

My van has an auto-stop feature that shuts the engine off at stop lights. This feature will now occasionally shut the car off, but then fail to restart it. We have stalled out at intersections with the van not restarting for up to a full minute. This is incredibly dangerous and needs to be addressed immediately

Starter is very weak when hot. 2 hour drive in summer heat and the van would not start after stopping at a gas station.

Auto start stop feature caused car to shut off at lights- happened 4-5x. Very dangerous. Battery replaced but then still had issues. Starter replaced.

Vehicle with 37k miles. When the idle stop feature is activated at a stop, it causes the vehicle to stall requiring a restart. The starter occasionally does not work as well. Starter and battery was replaced at 12k and the issue has resurfaced. This poses a significant safety risk.
