I own a 2023 Honda Pilot. On two separate occasions while the vehicle was being driven, the vehicle experienced multiple system warnings and a significant loss of steering assistance. The first incident occurred before July 16, 2026, at approximately 40,605 miles. While my wife was driving, multiple warning lights illuminated and the steering wheel suddenly became extremely stiff and difficult to turn, although the engine remained running. She was able to pull over, turn the vehicle off, and restart it. After the restart, the warning lights disappeared and the steering returned to normal. I brought the vehicle to John Eagle Honda of Dallas on July 16, 2026. The dealer's repair order documents: “CUSTOMER STATES MULTIPLE LIGHTS CAME ON WHILE DRIVING AND STEERING WHEEL GOT REALLY STIFF BUT VEHICLE WAS STILL RUNNING.” The dealer reported that it performed a battery check and charging-system test, found no stored diagnostic trouble codes, could not duplicate the condition during a test drive, and performed no repair. The problem occurred again on September 8, 2026, at approximately 42,511 miles while my wife was driving. Once again, the steering became extremely difficult to operate. During this second incident, my wife also reported that the brakes were not functioning normally. Multiple warning lights and system-failure messages appeared simultaneously. Photographs were taken of the instrument cluster before the condition cleared. One message specifically stated: “Electric power steering system problem. Steering assist not available. Do not drive.” Another stated: “AWD All wheel drive system problem. Only front wheels may be powered. See your dealer.” The instrument cluster also displayed additional warning indicators associated with other vehicle systems. This is particularly concerning because the failure has now occurred twice while the vehicle was being driven. Turning the vehicle off and restarting it has caused the symptoms and warnings to disappear.

The rear passenger-side (second-row, right-side outboard) seatbelt warning system is defective, repeatedly triggering false "unbuckled" alarms even when a passenger is securely buckled in. This is a known manufacturing defect involving the occupant detection sensor inside the seat cushion frame, which sends intermittent, incorrect signals to the vehicle's computer. The defect presents a severe safety hazard. The continuous, loud chiming distracts the driver and causes immediate "alarm fatigue." This forces the driver to ignore seatbelt warnings, creating a dangerous situation where a rear passenger (including a child) could actually become unbuckled without the driver realizing it, significantly increasing the risk of injury or death in a crash. The vehicle was taken to an authorized dealership for inspection, but technicians reported they could not replicate the intermittent failure at that specific moment. However, the system immediately failed again the very first time a passenger sat in that seat after leaving the dealership. The defective seat cushion frame and its internal components remain in the vehicle and are fully available for inspection. The failure began intermittently and has now become a persistent issue. There are no prior warning lights; rather, the seatbelt warning chime and dashboard graphics activate and continuously flash/alarm while driving, falsely indicating the occupant is unbuckled when they are actually safely secured. This issue matches the parameters of Honda Service Bulletin 23-018 and the active NHTSA safety investigation into this model.

I was stopped at a stop light on a very busy road. The vehicle went into Auto Idle shut down. When the light turned green, I attempted to press the gas but the engine was completely stalled and would not restart. I had to put the vehicle in park, turn off the vehicle, and completely restart it for the vehicle to be able to successfully clear the busy intersection. After this incident, the vehicle would inconsistently give me the Auto Idle System Problem warning when first started. I chose to disengage the Auto Idle system until I was able to take it to the dealer. They claim it is the electrical charging wire which is an 8,000 dollar repair for a 3 year old vehicle. We are currently awaiting the inspection from our extended warranty.

7/25/2025 i was driving my wife’s pilot between 55 and 60 mph when the vehicle alerted me to several warnings and the braking system stuck at the top of the pedal not allowing the vehicle to slow in a construction zone. I was able to limp the vehicle home but the vehicle was extremely difficult to slow at red lights. The vehicle was towed from residence after sitting and the tow truck driver said the vehicle was not showing any warning signs. The dealership in paducah test drove the vehicle and did not see anything wrong with it. They subsequently checked and there was a diagnostic for brake booster failure. The vehicle has 41,000 miles on it. In addition it went to the dealership at 9,981 miles for electronic parking brake sticking and the ike dealership said there was nothing wrong. There are other reports of woners on youtube who have had this failure or similar with one member having to ditch the vehicle. I almost wrecked and hit a vehicle that slowed in front of me. The system thew error codes to include failure in electronic steering, transmission, hill descent, electronic braking, and others. I recorded the errors on the dash. This vehicle has also thrown airbag error with only a few thousand miles. The vehicle has side panels that have fallen off and and seals on the panoramic sunroof that have failed.

I wanted to share a very scary incident that occurred while I was slowly creeping into a parking space in a parking garage. With my foot over the brake, as there were children in the area from a car that had parked to the right of mine, my car suddenly surged forward at a high rate of speed. It ultimately crashed into the 3-foot safety wall with tension wires of the parking garage. Clearly there is an issue with the propulsion system that accelerated my car forward. It's unknown to me if there was also an electrical issue involved in this propulsion failure. The car is available for inspection. The Honda dealer examined the vehicle but was unable to reproduce the issue, indicating that there was nothing wrong with the car, no codes stored of any relation to this incident, and that it was safe to drive. Additionally, I would like to mention that there was no warning lamps lit up on my dashboard before the incident and none appeared after the crash. My insurance was notified, and they deemed the car undrivable. The insurance representative is scheduled to inspect the car tomorrow. This is the first time my car accelerated on its own at a high rate of speed.

All listed problems act sporadically. Dangerously Defected 2023 Honda Pilot. Numerous problems with vehicle over several months. Kept taking it back to Charlie's Honda and was told they could not reproduce the problems I was stating. The Vehicle will bog, hesitate and jerk while driving. Charlie finds nothing wrong. Actually all items that are functioning incorrectly, Charlie's tell me they cannot repair anything when they can not reproduce the problem. They tell me that the 10 gears are so close that they skip? Sorry, that's ridiculous! Finally I called previous Owners, (Which Charlie's Honda refused to give me until I had to show them the Chapter 10 S1475 I had with me.) [XXX] from Herman, ME. Ph # [XXX]. They told me to tell you to please call them because they are very upset. After several times taking the Honda back to Charlie’s with no repairs done they went to get a different vehicle at Charlie's Toyota and the Toyota Manager told them that the Honda Pilot was a very dangerous vehicle and will not be put out on the Lot for resale. The [XXX] stated that they almost crashed while taking a left at an intersection with their children in the vehicle because it almost came to a complete stop. This serious problem is doing it to me now and this is why I’m taking this action. The [XXX] left the Pilot at Charlie's Honda for several days but Charlie's said they could not reproduce the problem. Just a few of numerous defects stated below and reported to Charlie's Honda but received no repairs, just excuses : The Airbag says off when a 175 lb person sitting in the front passenger seat. Rear camera does not register an object. I was told it didn't work because it was 1 inch from rear side camera and it was too narrow. nothing done. Speed said I was doing 85mph. I was doing 40 mph. mechanic said he sees them register 100 mph. nothing done. The tech screen goes black. Cannot shut radio off. After trying 3 times. Much more to report!

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.
