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!!

our family was driving on the interstate at 70mph, when the electronic system malfunctioned. The car said every system was failing and to see dealer immediately. The car immediately stopped accelerating, steering wheel shook, and car was difficult to control on the busy, holiday weekend interstate traffic. We had to be towed to Honda dealership, where they "fixed" the problem and we were good to go. 30 minutes later on the busy interstate, the same problem occurred again. Electrical, braking system, brakes started smelling hot. We had to drive on the interstate shoulder at 20 mph for 2 miles to an exit with our family of 5 and our dog. A second tow on Thanksgiving Eve. There were absolutely no warnings from the vehicle before the issue began. The car was bought with 320 miles on the odometer on November 20, and this occurred on November 22 with 570 miles on the odometer. From what we keep reading, we need 4 repairs for the same issue in order for the car to be considered "not operable" or "not safe." Are we supposed to drive on the interstate a few more times , get towed 2 more times, and just hope that we aren't hit and killed by a semi truck after our car suddenly stops accelerating? From looking online, there have been a large number of complaints with exact or similar issues. Does someone have to get killed for something more to happen?

Vehicle will randomly display multiple warning lights- usually starting with the braking system, until all warnings are triggered. This has happened about 10 times so far. Happens in a variety of driving situations. When car is parked, it then requires multiple presses on start button to turn the car off. Every time this happens the rear lift gate is completely disabled and unable to open. About 11/15/2023 I have a video of the errors I can provide- it is a large file and can’t be attached with the other photos. The error also occurred one time while driving at about 70mph using the adaptive cruise. There were no vehicles ahead, but one was approaching from behind- the vehicle brakes or the cruise controls caused the car to rapidly decelerate. I had had to push the accelerator to avoid causing an accident with the person behind me. I had the passenger take a photo of the dashboard warnings. About 11/3/23

Car wouldn't go more than 25-30 miles/hour and rpm was at 5-6, had to use blinkers on highway. Luckily there weren't any injuries, i was scared of the situation as I was travelling with my toddler and newborn. After reaching home, car wouldn't reverse. I had shutdown and started the car multiple times before i could reverse. There was smell as if something was burning in the engine. I shutdown the car for 15-20 mins for smell to go away and restarted the car again, that is when check engine light was turned on with warnings about transmission, AWD and emission systems. What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission failure, AWD system failure, Emission system failure. Has the problem been reproduced or confirmed by a dealer or independent service center? Confirmed by dealer, full diagnostics not available. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings before the failure. Dealer was saying about repairing the transmission, and also mentioned the car value will be depreciated significantly. I traded in the car for new pilot, as transmission problem are recurring and also losing significant value on the car. My loan and monthly payments went up because of something i didn't do. I am being punished for the someone else mistake. Dealer wouldn't provide any incentives too.

2PE25017 · 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.

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.
