-Defective Starter. -Starter randomly fails to restart vehicle after being warmed up. -When the DC motor internal copper windings get heat soaked after being driven and warmed up, the motor's internal resistance gets too high to draw sufficient current to turn over engine properly. This happens when intentionally shutting off motor (ie. getting gas, going into a store then coming out in a few minutes), the engine either will not crank at all, or cranks about two engine revolutions, will not start and then stops trying and remains in full accessory mode. It will not attempt a restart either. The only remedy is to fully shut down the vehicle, then try a fresh start after a few seconds. Sometimes it will start the engine, sometimes it will repeat the issue and you have to try again. This is EXTREMELY DANGEROUS when this problem occurs when the vehicle is at an intersection or traffic light, shuts itself off due to the auto-start/stop, then fails to restart the engine when expected when the light turns green. Especially at traffic lights if you're the first car in line., and especially if you're the first car to go with traffic behind and in a single lane of traffic. Having to totally shut the car down, then do a fresh restart while blocking an intersection with tons of cars behind and all waiting on your car to decide if it wants to re-start with cars flying around you into the shoulder or ditch to get around is an extremely dangerous position to be in, forcing other drivers into doing ridiculous things to get around you and WILL if not already cause major accidents. I believe Honda knows this is an issue. They are blaming bad batteries and alternators which can easily be ruled out with independent battery and alternator testing in the vehicle, while the problem of no/slow cranking remains. The problem IS defective starters, that have or will absolutely cause accidents by stranding vehicles in intersections because of failures to restart.

I am reporting a critical safety issue regarding the auto-start-stop system on my 2025 Honda Odyssey. On June 15, 2026, the vehicle's engine shut off at an intersection as designed but failed to restart, stranding the driver in active traffic and presenting a severe safety hazard. I previously brought the vehicle to an authorized Honda dealership approximately two weeks prior to this incident after noticing early symptoms of this failure. At that time, the dealership diagnosed the issue as low battery voltage and replaced the battery; however, this repair did not resolve the underlying fault. The vehicle continues to unexpectedly stall during traffic stops due to the auto-start-stop failure, representing an ongoing and significant danger to the vehicle occupants and other motorists.

This event has happened multiple times in various situations. While sitting at a red light the auto idle stop feature was engaged and the engine turned off as normal. Upon lifting my foot off the brake, the car fails to restart leaving me stranded in the middle of the intersection. This caused an unsafe situation as I was unable to restart the vehicle until after a few tries, leaving cars having to navigate around me in busy intersections. I have also had situations where I was unable to start the car while in park. It would start after the second try. This car was purchased in Fall 2024 and started showing this issue less than 1 year after purchase. Given the age of the vehicle, it should not have battery or starter issues this early on in the lifecycle of the vehicle. Looking online, other 2025 Honda odyssey drivers have posted similar issues. At first I thought it was just a fluke, but lately I have been having more frequent occurrences. A recall must be issued on the battery/starter to prevent future accident that is just waiting to happen. Being stranded in an intersection is incredibly unsafe.

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.
