The malfunction involves the Auto Idle Stop / Auto Start-Stop restart system on my 2025 Honda Odyssey, including related battery, charging, starter, starter relay, brake switch, and Power Distribution Module components. The vehicle is available for inspection upon request. The vehicle has shut off while stopped in traffic, usually at a red light, and failed to restart normally. This has happened four separate times. This puts my safety and the safety of others at risk because the vehicle can become disabled in an active traffic lane or intersection, creating a rear-end collision hazard and blocking traffic. I took the vehicle to Hill Country Honda in San Antonio, Texas. I told the dealership the vehicle had stopped and failed to restart normally multiple times, and I provided video and pictures to the service advisor. The dealership stated the battery had run down because of the Auto Idle Stop system and charged the battery for approximately two hours. I was also told that if it happens again, the procedure may be to charge the battery again before moving forward with further diagnosis or repair. As far as I know, the dealer has not reproduced the failure while in possession of the vehicle. However, they were made aware of the repeated failures and reviewed the video/pictures I provided. I do not know whether American Honda has inspected the vehicle. It has not been inspected by police or insurance representatives. Warning messages appeared during the failure, including “System problem detected. Shift to Park” and “To continue to drive, depress brake pedal and push switch.” These appeared when the Auto Idle Stop system had shut the engine off and the vehicle did not restart normally. I had no clear warning before the first incident.

I was waiting at a stop light. The idle system kicked and the vehicle turned off, as expected. Upon lifting my foot off the brake, the vehicle failed to start and the car went into park. I was unable to restart the car after holding the brake pedal down and pressing the start button multiple times. After many failed attempts, I shut off the power to the vehicle, waited a min or so and restarted the vehicle. I then put the car in drive and continued thru the intersection. This was in a busy intersection and could have easily caused an accident, but thankfully it did not. This is the 3 time this has occurred with this vehicle.

My 2025 Honda Odyssey has experienced the same problem 4 times when stopped at a light. The engine shuts off when stopped at a light but then fails to restart and instead the vehicle automatically shifts to park and stalls; the battery light illuminates and the whole vehicle has to be shut off before the vehicle will restart and be able to shift into drive. It appears this is a problem with the "Auto Idle Stop feature." It happened twice a few weeks apart and then happened twice during the same 30-minute drive. The vehicle also jumps/jerks forward occasionally when my foot is removed from the break at a stop sign or light in a way that doesn't seem normal.

The auto start and stop feature failed on numerous occasions. So when I am in the middle of a road stopped waiting for a car to turn my van will autostop but then it fails to restart. This has caused me on numerous occasion to be stalled out in the middle of busy roads and intersections. I almost was involved in an accident that was a near miss luckily. I have young children and I fear for their safety in our van as this issue can cause a serious accident if not corrected.

When the engine shuts off while braking at a light/stop sign etc occasionally the car will fail to turn the engine back on and the car will go in to park and the only way to get in to drive is to restart the car. This happens once or twice a month.

Auto Idle Stop feature has caused the vehicle to stall / shut down at a stop light on several occasions causing hazard when we can't drive. Entire engine has to be stopped and restarted which is scary in heavy traffic.

After approximately 60 miles of highway driving, I was stopped at a stop light and the auto engine off feature automatically shut the engine off. When I lifted my foot from the brake pedal in attempt to accelerate forward, the van did not turn back on and a battery warning light showed on the dash. I attempted to restart the van without success x 2, it was not turning over. My van was stalled in the middle of the road, cars passed around on both sides. Upon my third attempt to restart the van, it did restart and I have had no further issues since. Though, I have been shutting off the auto engine off feature since that time. I understand there is a well known issue with the auto engine off feature of Honda Odysseys in this generation. I am respectfully advocating for a formal recall as a stalled van in the middle of traffic poses significant risk to the public.

This was an auto stop-start system failure. The Honda dealership in Frisco inspected and attributed this to battery life but did not guarantee this was the cause of the issue. There were no other signs of failure prior to the incident. A description of the incident is below. While turning right departing a parking lot, the vehicle auto stop-start enabled during the brief stop and the feature turned off the vehicle. When accelerator was pushed to proceed, the car started flashing lights with a warning message on the dashboard, the car was then automatically put into park by the system, and would not proceed to move without turning the vehicle off and back on. If this had occurred in another location, it would have been extremely dangerous as it took some time to turn the vehicle back on.

Engine fails to restart after the Auto Idle System shuts it down, leaving vehicle stranded in traffic. The issue is sudden and unpredictable, and may not appear in inspection. A stalled car in live traffic is a safety concern. The vehicle is at a dealer for diagnosis and repair. No warning appeared before the problem began happening. (About 5 times in 2.5 months.) Sometimes when it occurs, a brief error message seems to appear on the dash, but quickly disappears. It usually takes cycling through restarting the car to get going again. Not a good environment to stop and take video, although it's almost impossible to record.

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.
