No Restart After Auto Start/Stop EngagesOpened March 26, 2025, still open

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.the federal safety agency 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.

I am reporting a catastrophic safety defect and a failure of a federal recall remedy on my 2015 Acura TLX. My vehicle was previously identified as part of the connecting rod bearing recall (the federal safety agency Campaign Number: 23V751000). The dealership performed the official recall inspection/remedy in February 2026. However, in September 2026, the engine suddenly developed a loud, metallic knocking sound coming directly from the motor. A metallic knock is the primary warning sign of imminent rod bearing failure, which poses a severe safety risk of sudden engine seizure and stalling while driving at highway speeds. I contacted Acura Customer Service to report that the recall remedy failed and that the vehicle is unsafe to operate. Acura corporate has completely denied my claim and refused to take corrective action, despite this being a direct, unmitigated failure of the recalled component.

My 17 year old son drove across town about 6-7 miles from home, on a back road. Out of nowhere, his 2015 TLX started to make a sound like knocking or thumping. Just moments afterwards, most if not all of the engine warning lamps illuminated at once.. He pulled off as best he could there was a loss of power and massive amounts of steam pouring out from the under hood. At sunrise I went to the car to wait for AAA I was astonished at the mess on the pavement under and around the car, and even more surprised to hear from my mechanic told that the engine had seized. I remember my mechanic using the word "warped" to describe it to me. I had him replace the engine, as I was I unaware of the recall at that time. It was not inspected by anyone besides my mechanic.
