2025 Honda Odyssey with approximately 22,000 miles. On multiple occasions while stopped at traffic lights or stop signs, the vehicle's Auto Idle Stop feature shut the engine off normally. When I attempted to accelerate, the engine failed to restart, leaving the vehicle disabled in the travel lane. The battery warning light illuminated, and on one earlier occurrence I believe a "Shift to Park" message may also have appeared. I was able to restart the vehicle by pressing the Start button, shifting back into Drive, and continuing normally. The most recent incident occurred while stopped at a traffic light. When the light turned green and I pressed the accelerator, the vehicle did not restart or move. I had to manually restart the engine while stopped in the intersection before I could proceed. This created a safety concern because the vehicle unexpectedly became disabled in active traffic. The vehicle has never exhibited difficulty starting during normal operation, either when cold or warm. The problem has only occurred after the Auto Idle Stop system shut the engine off at a stop. The vehicle has not yet been inspected by a Honda dealer, but an appointment will be scheduled.

After AIS engaged, the engine wouldn’t come back on. This has been at intersections, etc where it was dangerous to have no engine. It is ridiculous that the feature has not been removed after problems going back to the 2018 model. All to game an emission standard. Shameful.

When stopped at a red light today, our minivan's Auto Idle Stop (AIS) system stopped the engine with the brakes depressed (as advertised). Once the light turned green, the driver released the brake to re-engage the motor, but the starter did no restart the minivan and a battery light flashed on. The start button had to be pressed several (~4) times to get the motor to restart and to turn the battery light off.

This has been addressed by the dealer once before and the starter was replaced, however the problem is happening again. The auto start/idle feature will not start the car back up while stopped on occasion. For instance, yesterday while stopped at a red light the auto idle/start feature kicked in, as expected. When releasing the brake to drive when the light turned green the car beeped and would not start again. We had to power the whole van down at a busy intersection and restart. Thankfully it started. We didn’t catch what warning lights flashed when the van beeped, but no warning lights were present before the issue. As mentioned, this has happened before to the point the dealership replaced the starter. But unfortunately, it is happening again. The van often has a rough start as well when using it, but not every time.

The vehicle experiences dangerous, unexpected engine stalling immediately following an Auto Idle Stop event. Upon coming to a complete stop at intersections, the engine shuts off as designed, but fails to automatically restart when the brake pedal is released. The vehicle completely locks up, leaving my family stranded in live traffic and requiring a manual reset of the ignition, which takes time to restart several minutes or longer. The local Honda dealership states they cannot duplicate the intermittent issue, posing a severe ongoing safety hazard. Honda has a ticket open for the year of my Honda but has yet to approve or make a fix. It's happened several times first notice it back on XXX and Honda dealer could not duplicate the issue so they did nothing. It has happened several additional times before now but this last time it happened XXX we were on a highway at night and it almost caused us to be rear-ended. The first times it happened back in XXX I sent them a photo of the dashboard light up when it was stalled, but they said they couldn't duplicate the issue and did not fix anything. This was all done through First Texas Honda in [XXX], which is where the vehicle is at now. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought a brandnew vehicle 1/31/2025 and it was a White Honda Odyssey 2025. I was in search of a bigger and safer car for my family of 5. Within months I had major issues with the vehicle. I would bring my car in and it would get returned unfixed. My vehicle has now gone in for a 6th time (twice in a week) for service for shutting off while the vehicle was IN MOTION (on the highway , busy rotary and roads) I have spent hours and hours and hours speaking to people and James Brown at Parkway Honda. I have been lied to about how much my vehicle was driven and tested with them not knowing I had tracked the mileage on there at dropoff and checked at pickup. I feel very small in this situation as Parkway Honda keeps brushing me off and not fully getting that a vehicle shutting off while in motion on a highway or in a busy rotary is wildly unsafe. My kids and I have been SOO lucky that this has not been fatal. Honda keeps saying it's the battery, etc. My car was in there for over 3 weeks last Summer for this issue and has been in and out multiple times and it was brand new. This is criminal on their part and they know they are bigger than I am and im sick of it.

My vehicle has experienced repeated unexpected engine shutdown/no-start events, creating a significant safety hazard. The engine has unexpectedly shut off or failed to restart while stopped in traffic and while entering traffic, resulting in a sudden loss of propulsion. On one occasion, the vehicle would not restart for approximately one minute. The vehicle was inspected by an authorized Honda dealership, and the starter was replaced under warranty in July 2025. The repair did not correct the problem. Since that repair, the same failure has occurred multiple additional times. The issue has now occurred at least six times over approximately one year. Because the condition is intermittent, the dealership has not permanently identified the root cause. The vehicle is currently being returned to the dealership for further diagnosis, and I have requested that the matter be escalated to Honda Technical Assistance (Tech Line) and Honda Engineering. This defect creates a serious safety concern because the vehicle can unexpectedly lose power while in or entering traffic, increasing the risk of a collision. There were no consistent warning lights or messages before the failures, and the condition occurs intermittently without warning. The vehicle remains available for inspection.

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.
