The vehicle's Auto Idle Stop (AIS) system failed to restart the engine after engaging at a complete stop. The affected components are the engine, starter motor, and AIS control software. The vehicle is available for inspection upon request. On XXX, at approximately 7:43 PM, the AIS system engaged while I was stopped at the intersection of [XXX]. Upon releasing the brake pedal, the engine failed to restart. The vehicle became fully immobilized in an active left-turn lane with traffic behind me. I was required to shift to Park and manually depress the Start button multiple times to restore power. Multiple vehicles behind me began sounding their horns. A minor child was a passenger in the vehicle. This is not an isolated incident. The vehicle has been presented to Howdy Honda, in Austin, Texas, for the same defect on three to four prior occasions. On the most recent prior visit, the dealer replaced the starter motor — the specific remedy prescribed by Honda Technical Service Bulletins 23-008 and 23-009. The vehicle was returned to me as repaired. The failure recurred the same day. The defect has been confirmed and repair attempted by the authorized Honda dealership. The manufacturer has been on notice of this defect class-wide since at least 2018. Prior to and during failure events, the instrument cluster displays a Red Exclamation Mark warning light and/or a "Brake System" warning light. These warnings first appeared in conjunction with the initial AIS failure events and recur with each subsequent incident.

My 2024 Honda Odyssey has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off while stopped at a red light or in traffic. Normally, the engine should automatically restart when I release the brake, but on several occasions the vehicle completely shut down and I had to manually restart it. During one incident, the vehicle would not restart for approximately 1–2 minutes despite repeated attempts. This left the vehicle disabled in traffic and created a serious safety concern. The problem has occurred multiple times.

The van has trouble restarting. This can appear as both a sluggish restart and a complete failure to restart. The van has failed to restart both during quick stops like refueling and during the auto-stop feature at a stop light. When this happens, the driver must completely shut off the van and restart, which is a safety issue when stuck while blocking traffic. The van is having the starter replaced for a second time after the dealer determined the starter was failing. The starter was replaced in 2025 under warranty because the dealer determined the starter was failing. There are no warning lamps, but the starting does start to slow down over time. We missed the slow down the first time until it failed to restart because the onset is gradual. We only noticed the second time because we'd already encountered the issue. The two dealerships we've taken the van to for this issue were both hesitant to do the work, claiming trouble recreating the issue.

I could not get it back in drive and had to turn the car off then back on. Meanwhile I am stuck in the middle of the road with traffic. This has happened several times before.

Yesterday (8/21/2026) my husband took this vehicle in for a routine oil change and upon the 100 point inspection was informed there was an oil leak somewhere from the engine. This vehicle is barely 2 years old and barely at 30,000 miles. There were 0 signs of a leak somewhere we had no idea. They completed diagnostics and determined it was the axle seal. Thankfully this was covered under warranty but their master mechanic shared with my husband that this is a very well known issue with the 2024 models and the fix is using the newer manufacturing parts. Again, there were no visible signs of a leak, there were no vehicle computer warnings of an issue other than the oil life alerts that are programmed.

Car purchased July 4, 2024. Idle stop/start was working but after several months, it became defective. After driving for some time, idle stop/start wouldn't work properly and cut the engine off when idling. I would have to turn the car, open my door, and try to restart the car. It also occurs after parking, turning off the car and less than 10-15min attempt to restart. Most of the time, it'll start after 1 or 2 attempts. Except today 07/31/2026, I got home and parked. After 20min, I tried to start my car and after 10-15 attempts, it wouldn't start. After waiting 2 hours, the car finally started.

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.
