While waiting at a stop light, the engine turned off and the vehicle forced itself into park. Taking my foot off the brake, had no effect. I was not able to put the vehicle back into drive. I had to shut off the engine and restart it in order to drive again. Of note, the AC and carplay were running at the time of the engine failure. No warning lights appeared. Cars behind me were honking at me. I have an appointment scheduled with the dealership to assess the auto-idle function.

While driving our 2025 Honda Odyssey, my wife came to a complete stop at a red traffic light. The vehicle’s Auto Idle Stop feature was enabled, as it is by default each time the vehicle is started. When the light turned green and she attempted to accelerate, the vehicle would not move. The engine appeared to be running/revving when she pressed the accelerator, but the vehicle remained stationary as though the brake was still engaged. A message appeared on the instrument panel instructing her to depress the brake pedal and press the start/stop button. Initially, we believed the electronic parking brake might have been engaged, so she attempted to disengage it, but this did not resolve the problem. She was stuck in an active traffic lane at an intersection and unable to move the vehicle, creating a significant safety concern. Another person advised her to completely turn the vehicle off, wait approximately 10 seconds, and restart it. After doing so, the vehicle operated normally again. After this incident, I learned that NHTSA is already investigating Auto Idle Stop/no-restart complaints involving Honda vehicles, including 2025 Honda Odysseys, under Engineering Analysis EA25-004. I also learned that Honda has previously communicated with dealers regarding Auto Idle Stop no-restart incidents involving 2023–2025 Odysseys. This was an extremely concerning failure because the vehicle unexpectedly became immobilized at a traffic light and could not be driven until it was shut down and restarted. I am concerned that this could happen again in a much more dangerous situation. I am submitting this complaint so that this incident is documented as part of NHTSA’s investigation and to request that NHTSA determine whether a safety recall or other corrective action is necessary.

My car slammed on the brakes on its own. I was almost rear ended. I was going 45-50 miles an hour. I think it saw a shadow. Previously it has alerted me to brake because of shadows. This is the first time it braked hard on its own.

Vehicle turns off unexpectantly at red lights/intersections when auto idle engages and will not restart automatically. It takes 1 to 2 minutes for the vehicle to restart. There is no predicting when the issue occurs. Causes vehicle to be immobile in busy and congested intersections which results in safety issues to us and oncoming traffic. There is a potential for a head on or T-bone collision when this happens. We've had starter replaced before at 22,000 miles and now we have to do it again at 36,000 miles. The Honda dealer said he sees this issue twice a week so we aren't the only ones. To my knowledge, Honda has yet to come out with a permanent repair.

When the engine is hot, the car hesitates to start for a couple seconds. Occurs on really hot days especially after stopping and starting the engine such as after getting gas or on idle stop at a redlight. The motor starter has been replaced by Honda to a new one but the issue can re-occur as the part being replaced is the same with the same build and will likely fail again in hot conditions.

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.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
