Next to the 2024
The 2025 is too new for a fair per-year comparison. It has 107 complaints so far; the 2024, on sale longer, has 39.
Top problem
One problem takes up much of the file: stalling, named in 48 of the 107 complaints (45%). Too few of the stalling reports give a mileage to say when it starts.
Crash, fire and injury reports
Only 3 of the 107 complaints (3%) report a crash, a fire or an injury, well under the 6% typical of vehicles on this site. Counted separately (one report can carry more than one), 2 reports mention a crash and 5 people were hurt.
Recalls behind the top problems
No recall on file is on the same system as stalling. For those, the complaints are all there is.
When owners filed
Complaints are still climbing. 2025 brought 26, the most of any year so far. So far in 2026, 80 more have come in.

NHTSA investigations

EA25-004opened Mar 26, 2025
Engine · model years 2016 to 2025

No restart after auto start/stop engages. Open.

NHTSA summary
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 review
