The driver seatbelt was soaking wet after a rainstorm. The vehicle does not have a sunroof. Upon further inspection the airbag and its electronics were also soaked in water. It has never been in an accident or had any work done to it. There is a factory installed roof rack(Sport model). I am concerned for the safety in the function of the airbag and seatbelt tensioner in the event of an accident after being soaked in water an unknown amount of times. Secondary, possibly related issue. The rear drivers side door will randomly not unlock/open from the exterior(have to reach through and use the interior handle). Posing a safety issue in the event of child removal in an emergency.

1. Rear tailgate latch will not always release when pressing the dashboard button or remote fob button. The tailgate will attempt to rise, go about 1/2 inch, stop, beep 3 times and then close again. It can only be opened after this by manually pulling on the outside handle and giving it a sharp jerk upwards. 2. While trying to investigate a metallic tapping sound in the rear of the vehicle, I looked under the rear bumper and located a wiring bundle that had lost its support from a plastic clamp. The bundle was frayed, and there were exposed and frayed wires visible showing the copper inside the insulation.

Sunroof glass exploded: While driving in light traffic -- approximately 65 mph -- I heard a loud crash exploding sound and then the sound of glass breaking. No other vehicles were near me but I quickly scanned my front, back, and side windows and mirrors and nothing was broken. No warnings on instrument panel. I could hear wind coming in the vehicle and realized it was coming from the sunroof. I pulled off at the next exit and inspected the top of my Honda Pilot. There was about an 8–10-inch hole in the sunroof glass above the driver's seat with jagged glass angled outward from the hole. No signs of any other damage such as feathers from a bird or scratches from a rock. Just a hole and broken glass. I continued to the drive to my home -- about 20 miles. By the time I got home, more than half of the glass had broken off, leaving an opening about 18 X 30 inches or more. Upon closer inspection, it was clear there was no other damage from other objects just as a rock or animal/bird. It was a very frightening and unnerving experience, especially driving on interstate traffic. I contacted my Honda dealer, and it was suggested I contact Honda customer service. We have filed a claim with our auto insurance.

I purchased my 2023 Honda Pilot on April 7, 2023. I had to wait for it to come in which happened roughly 2 weeks later. Within a month or so of having the vehicle while sitting at a traffic light I got 2 warning lights. One being the collision mitigation system problem see your dealer and immediately followed by adaptive cruise control problem see your dealer. I called the dealership to make them aware of the problem and was asked to make an appointment to bring my car in. Upon stopping and turning my car off and starting back up the warning lights were gone. I didn't think too much about it. In August when I had my car in for routine oil change they checked the issue and was unable to find anything. Around this same time my driver side front bumper started gapping. I was told that the clip was either not installed properly or was bent during manufacturing. (still waiting for that back ordered part to repair) In November while traveling with my niece and nephew again stopped at a traffic light EVERY SINGLE warning light started coming on. My dash was lit up like a Christmas tree and the lights were coming one after the other. I pulled over, not only would my car not turn off, my back liftgate would not work either. I was 4 hours away from home. I called the local Honda dealership where I was as I was in a panic. While on hold I was finally able to turn my car off by holding the start/stop engine button for several seconds. When I started my car again all of the lights were still on and lighting up one after the other. As I made my way to the dealership they all went off and all was normal again. I took my car to my local dealership once I got home. Dealership said they were not able to find much except the faulty camera sensors and Honda suggested to start there. (On back order) However in the meantime I was told that I should NOT TRUST ANY OF MY SAFETY FEATURES. My job requires a significant amount of driving and at this point I feel like I have gotten a lemon!!

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.
