The engine required a short block replacement at approximately 40,000 miles. There was a severe knocking sound and the dealer diagnosed heavy scoring and abnormal wear present on the front bank cylinder walls. The result was excessive internal engine clearance and cylinder wall damage. Engine cylinder piston block holes were worn beyond spec. After 33 days the vehicle was returned and developed a growling/grinding noise when the AC was in operation and at lower speeds that followed the RPMs. Vehicle was returned to dealer and told sound was normal operation for this model and stated it was coming from AC Compressor. Independent shop verified 2 days later AC compressor was failing and possible metal contamination. AC compressor is backordered with no ETA. Advised to not use AC or Defroster to avoid seizing and causing serpentine belt to snap. Advised Honda Customer Care and assigned Case Manager who was made aware of knock and compressor failure and contacted dealer who stated vehicle could not be seen for 7 days due to being booked. Advised Case Manager of vehicle safety concern with internal engine failure damage and failing AC system and was denied emergency loaner or assistance and told it was all they could do. Vehicle now unsafe due to both with no timeline for fixing and known hazards due to severe engine failures and associated issues with main systems.

My husband was driving our family of 6 to [XXX] from the [XXX] area. We were on the highway in [XXX] when we heard a loud pop and the sunroof had randomly exploded. There's a thin cloth like screen between the glass and the inside of the vehicle. Luckily that screen was not open, otherwise, we would've have been cut up by the glass shards coming down. We arrived at our destination in Florida and took pictures of the broken sunroof. I called our insurance to file a claim. I also called American Honda and made filed a case. I was told to take it to the dealership and see if our extended warrantee would cover it. MPP denied the claim. This is very dangerous to have a random sunroof explode out of nowhere. Someone needs to take responsibility for this before people get hurt. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2023 Honda Pilot AWD Elite with approximately 46,000 miles. It has an engine idol feature that's suppose to restart the engine after idoling. I was in a parking lot waiting to enter into traffic when the engine completey shut down. I was able to restart the engine at the time. Again the same day I was at a stop light, the car was idoling and when the light turned green, I took my foot off the brake and proceeded to press the gas pedal, the car shut down completely and I had to restart the vehicle. I made an appointment to take my car to the dealership the next morning. On Friday May 1st, 2026. I brought the vehicle to the dealership but they told me they won't be able to see it until Monday. Saturday, I took my child to his soccer match and again, at the stop light before getting onto the freeway, the vehicle shut down after Idoling. The feature Auto idol/restart is automatically on when you start the vehicle. It will drive fine if you remember to turn the function off. Honda has no official recall on this. There was a similar software issue recall in 2025 but the dealership told me that campaign was closed.

PE25017 · Inaccurate Rear Passenger Seat Belt Warning Status

Opened Oct 28, 2025 · No close date supplied

Status: open (inferred from source dates) · Seat Belts; Seat Belts:rear/other; Seat Belts:status Indicator Switch

The Office of Defects Investigation (ODI) has received 6 complaints, and multiple Early Warning Reporting (EWR) field reports alleging inaccurate rear seat belt warning status. These allegations concern both false positive and false negative statuses in model year (MY) 2023-2024 Honda Pilot vehicles manufactured by American Honda Motor Co. (Honda). The complaints state that the rear passenger seat belt warning system is displaying inaccurate information to the driver for both second and third row seating positions. This can lead to the driver dismissing warnings regarding rear seat belt status. The inaccurate information can also cause the driver to believe rear occupants are buckled when they are not. This reliance on false information presents concerns for the safety of children and child seats located in the rear rows, especially in the third row where the buckled status is more difficult for the driver to visually confirm. ODI is opening this Preliminary Evaluation (PE) to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
