After going over a railroad track, at 15mph, several warning sensors appeared. Including brakes, power steering and several more flashed quickly. Power steering failed and I could not turn my wheel. It told me to not drive and see a dealer. Luckily I was in traffic and it was moving slow. I was able to turn my car off and back on and all the senor systems cleared. I took my car to the dealer, which it is at now, and they cant find a problem outside of wheel sensor going off in history. I dont feel safe with this car.

Driving down a 4 lane highway in Alabama, warning lamp came on stating “ STOP Steering assist reduced. Stop driving when safe”. Multiple other warnings lights came on—-Brake system, steering system, cruise control, lane departure, stability assist system, hill assist, trailer stability assist system(see multiple photos attached). When it was safe to do so, I pulled over…the steering was VERY difficult to manage. If I had to make a turn in traffic or had to make a sudden turn to avoid an accident, I would not have been able to do so as there was NO power steering. I turned the car off, let it sit for several minutes and the Steering Assist warning was off and I appeared to have power steering but several others lights were still on. Took the car the the closet dealer and only code found was a Low Voltage Code but nothing repaired as all warnings lights were off by then.

The auto idle stop caused my Pilot to not restart as I was taking my foot off the brake turning left on a busy road. I had to be towed as my car would not start. The Honda repair center said there is an Engineering Request ([XXX]) trying to gather information about the issue, but no fix other than having to turn off the feature every time I restart the car. I am now extremely concerned about my safety and others because if I forget to turn off this feature, my car could unexpectedly now stop working and I could immediately be put in an unsafe situation. Honda said they can’t automatically turn off the feature. They have shifted this responsibility to the driver of the car. This is not right and they don’t seem to care when I call 1-800-880-1072. All they said is it your responsibility to turn off the feature each time you get in the car rather than give me options. I asked repeatedly if I were to forget and my car won’t restart after an auto idle stop, what can I do. Could not answer other than I need to be mindful before putting the car in drive. This is so wrong, I could come up with several scenarios now my car could cause me danger and others if it stalled suddenly in a heavy traffic area. What are my option?

The automatic emergency braking system in my vehicle has repeatedly activated without any visible reason. The brakes engage suddenly even when there are no cars, curves, reflective surfaces, or obstacles nearby. This has occurred on straight, empty roads and in clear conditions. We have previously taken the car to the dealership for issues related to sensors and wiring, and were even told at one point to turn off certain safety features. Most recently, we went through the dealership and escalated the issue to Honda corporate, but they closed our case and claimed there is nothing wrong with the car. I am very concerned that this unresolved issue could lead to the brakes locking up in a dangerous situation, potentially causing an accident.

With the Idle Stop feature on (meaning the car will shut the motor off when coming to a stop, but keep electrical equipment working), my Honda Pilot, at random times, will completely lose all power when I come to a complete stop. This results in the car being unable to be operated and can lead to numerous instances of injury or even death. In order to have the car work properly again as it should, I have to recrank the car completely. Sometimes the motor turns over without issue, and other times it sounds like it struggles to supply power to crank the car. This was a known issue with Honda, with a recall in place to fix it. I completed this recall in April 2025. As of [XXX] (The same day of the MOST RECENT incident), my Honda Pilot is at Hubert Vester Honda in Wilson, NC for them to troubleshoot the issue further. Per their Maintenance department, Honda has opened up an inquiry further into this issue. My Honda Pilot is a 2024 with less than 23,000 miles on it.

The vehicle started having issues initializing the auto-ignition system. It would give various notification, like system warming up when it wasn’t cold, or system disabled for some reason. Then it started shifting to park when stopped at light. Then it stalled multiple times when the AIS would initialize. Dealer said it was bad battery and swapped it. Driving away from dealer after service approached a stop light and came to a stop. The vehicle stalled again and went completely dead. No electrical at all. Stranded at intersection.

I hope this message finds you well. I am writing to express my deep concern regarding the ongoing safety issues with my leased Honda, which I obtained in March 2024. Shortly after leasing the vehicle, I noticed that the sensors would frequently activate and deactivate without any apparent reason. In May 2024, while driving, all the sensors turned on, deactivating all safety features and causing the car to swerve. The sensor lights remained on the next day, prompting me to take the car to the dealership. I was informed that the sensor and a camera required repairs, which were subsequently addressed. Despite my concerns about the safety of driving this car, especially with three children, I was assured that the issue was resolved. I filed a complaint with Honda Corporate, and they indicated that the issue would need to recur 2-3 times before considering a different vehicle. Unfortunately, on [XXX], all the sensors activated again while I was driving, causing the car to stop accelerating in the middle of a busy road with my children in the back seat. This placed us in a life-threatening situation, as other vehicles were traveling at high speeds. The transmission light also turned on, advising to avoid high speeds. The next morning, I reported the issue to Honda and arranged for roadside assistance to tow the car to the dealership. During the towing process, the sensors activated again, and the car struggled to accelerate. Once at the dealership, I provided videos of the car's behavior to Ricardo, the service advisor, who acknowledged the severity of the issue. However, he later informed me that the sensors were not currently active, and the scanner could not detect any issues. Despite keeping the car overnight for further testing, they were unable to identify or repair the problem. I was advised to either pick up the car or leave it with them, but no loaner vehicle was offered. I am extremely concerned about the safety of driving this car.

Bought this brand new 2024 Honda pilot touring model on Oct 2023, the issue starts showing after driving it for only couple of hundreds miles, there is a very distinctive and constant loud popping and cracking noise coming out from the speakers while driving, no matter if the audio volume is set to high or low or zero or even when music player is turned off, looked it up online and found out it is a very common problem for Honda for years now, and it is not just for the pilot lineup, it also affects their other models like Passport & Odyssey, It has something to do with the wiring process and improperly manufactured terminal of the FAKRA connector for the infotainment system. They have service bulletin (#23-047 & #23-046) and safety recall for the previous year models, but not for 2024 Honda pilot yet, I think this issue affect safety because the popping & cracking sound is loud enough to distracting driver while they are driving to the point they cannot 100% focused on the road. And I'm sure my vehicle is not the only unlucky car for the 2024 Honda Pilot model, I hope Honda address this issue as soon as possible, and also please prevent this from happing in the future, this is not my first Honda car, I hope this will not be my last one.

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.

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.
