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.

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

Numerous times since purchasing my van it has failed to start. At first it was just random at a stop light when I would forget to turn off the idle stop. Leaving me stuck at stop lights with a vehicle that won't turn on without multiple attempts. More recently it struggles to start after stopping to run errands or get gas or in drive thru lines. Having to depress the break pedal to the floor (much further than needed to even stop the car) and press and hold the on/off button while it chugs and attempts to start. The issue was able to be recreated by the dealer and they indicate that it is a starter issue but the part is on back order. Upon further discussion it appears that this isn't an unknown issue and that there is a current investigation into this issue. However, the service manager indicated to me that this isn't common and this was a "one off" incident.

Auto idle/stop system engages while sitting at a traffic signal as designed. When attempting to proceed, the engine fails to restart and all electrical components completely shut off for several minutes. All components stop working (information screen, gauges, hazard lights, and door locks are non-functional) and the vehicle is unable to turn on for several minutes. This creates an unreasonable safety risk for the occupants of the vehicle and for surrounding motorists when this failure occurs in active traffic lanes as the vehicle when it is reasonably expected for the vehicle to resume propulsion and with no ability to turn on hazard lights to warn approaching motorists of the vehicle's disabled status. The failure of the door locks during the event traps the occupants inside the vehicle, which we are in Florida so, hot summer days the internal temperatures can reach deadly levels within minutes with no way to escape. The vehicle was initially inspected by a manufacturer authorized dealer service department on 7/8/25 and the issue was dismissed. The vehicle was again inspected on 7/30/25 by the same service department and confirmed. A starter motor assembly and relays were replaced by the dealership and the vehicle returned to use on 8/4/25. Again, on 8/5/26 the vehicle exhibited the same safety defect while in an active traffic lane. The vehicle was returned to the same service department on 8/6/26 where it remains as the date of this report with no communication on resolution for the problem from the manufacturer. There were no warning lights or messages prior to the failure.

UNKNOWN, while driving when I was waiting at the signal (waiting for green signal to move) my vehicle automatically shifting from direct to park gear.Once shift to park then no other gears/buttons do not work, only I can turn off the vehicle and restart then all gears/buttons work to move on. This safety issue happened three times (6/25/2026, 7/13/2026 & 8/10/2026) on the road. I took my vehicle on 7/14/2026 to the dealer and they said they didn't find any issue after keeping the vehicle for six days with them. If this issue happens while a vehicle is moving on the road it is going to be a big disaster. After the 08second incident I reported to the Honda manufacturer too.

Put the vehicle in park, turned it off, waited a few seconds and attempted to re-start it. Van restarted but very sluggish, like the battery was dead. Pulled in and parked. Van started normal the rest of the day. Took it to the dealer 2 days later. They noted the battery was a little low but no codes and no explanation for why it failed to restart. They checked alternator and starter and claim they are both good.

Vehicles turns off when the brake is pressed and does not turn back on. The van has to be put into park and the start button has to be hit 2-3 times before it will restart. This has happened 3 distinctive times where it was difficult to restart. We try to disable the start/stop system each time we drive. It has left us stranded at traffic lights for up to 20 seconds trying to restart the van, impeding traffic at high speed interchanges. The van does eventually restart but each time it feels like it’s getting more difficult. This problem first appeared about 1 year after purchasing the van with about 23k miles on it and now has 26k miles. There are warnings that display because the vehicle is still in drive when it shuts off and it needs to be placed back into park to restart it. It occurs the most during a long drive on the highway. It can be very jerky when it restarts, perhaps slamming into gear. It is available for inspection and I plan to go to the Honda dealership soon for a scheduled oil change. I have not been there since the 18k mile oil change.

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.
