Second-row right passenger seat belt buckler is malfunctioning and alerting when the seat belt is buckled. The alert is distracting as a driver and my children can not sit in that seat since we can't tell if they are buckled or not. The first time it malfunctioned was a week or so ago in the middle of May 2026 and the problem has only gotten progressively worse to the point we can't have anyone sit in that seat. I have set up an appointment for the dealership to look at this issue in June. No one else has inspected the vehicle so far.

My vehicle has already had recalls on the fuel system and brake pin. Now I have an auto idle stop system problem. The indicator light is constantly flashing. Two days ago I was stopped at a red light on a two lane road in the city. When I pushed in the brake the car did not come out of idle. It just stalled. It took probably 30 seconds to a full minute before I could do anything. My option was to restart. It created a situation for myself and others.

Second row, right side seat belt sensor is malfunctioning. It started about 6 weeks ago. Occasionally, when going around a turn, an alarm would chime and a red X would appear on the affected seat on the dash screen. It was very quick, and sometimes I just heard the chime and did not see anything on the dash. The issue has become more frequent over time, so that it went from happening a couple times a week to multiple times in one trip, not always when going around a turn. Just a few days ago, the passenger got in and buckled, yet the system showed that it was not buckled. The seat belt was securely latched. The alarm continued to sound and the dash showed a red X on that seat plus a red picture of a person wearing a seat belt. It was a short (about 1 mile drive) and the alarm went off the whole time. We had to reconfigure the vehicle so that seat is no longer being used. We contacted the dealer and they stated that our VIN has no recall or Service Bulletins related to the issue. We are taking it in to be inspected later this week. The dealer would not order any parts or schedule a replacement until they tested it themself.

The vehicle's Collision Mitigation Braking System (CMBS) is triggering 'phantom braking' at 50mph when there are no vehicles or hazards ahead. This occurs consistently on roads with dark asphalt patches/crack sealant. The braking is severe enough to cause a potential rear-end collision.

Recently the vehicle has developed an erratic behavior when a passenger on mid-row seat is using the seat belt, seat belt reminder goes on/off every few seconds displaying inaccurate information of when the seat belt is in use. I contacted my local Honda dealer describing the problem and informing them of Honda's service bulletin #TSB A26-027, which describes exactly the same symptoms my vehicle is having and they've been unwilling to address the issue, as the TSB is not an active recall.

Read full complaint

Component/System Failure: The right rear passenger seatbelt buckle/sensor appears to be malfunctioning. It intermittently registers as unbuckled even when the seatbelt is securely fastened. The component is available for inspection upon request. Safety Risk: This defect creates a safety concern by causing continuous distraction to the driver due to repeated seatbelt warning chimes and alerts. It may also lead to uncertainty about whether the passenger is properly restrained, potentially compromising occupant safety. Reproduction/Confirmation: The issue has been consistently reproduced during normal driving conditions. It occurs frequently, even when the seatbelt is properly latched. The issue has not yet been formally confirmed by a dealer or independent service center. Inspection History: The vehicle/component has not yet been inspected by the manufacturer, police, or insurance representatives. Warning Lamps/Messages/Symptoms: The seatbelt warning chime and dashboard alert activate intermittently while driving, despite the seatbelt being properly fastened. No prior warning signs were observed before the issue began. The problem first appeared in January 2026. Additional Notes / Assessment: Based on the symptoms, this appears to be a faulty seatbelt sensor or buckle connection issue causing false readings.

The vehicle previously experienced a steering wheel locking issue and was taken to the dealer for repair. The dealer stated the issue was repaired on December 11, 2024. On February 24, 2026, while driving on a public street, the vehicle hesitated or jerked slightly during acceleration and then appeared to operate normally. After a few minutes, multiple warning messages suddenly appeared on the dashboard, and the steering wheel became extremely difficult to turn and effectively locked while I was driving. I immediately activated my hazard lights. I was unable to safely pull over because the steering wheel would not respond properly, which placed me and other drivers at risk. I had to continue driving slowly until I found a side road where I could safely stop. I turned the vehicle off. When restarting, the warning messages reappeared. After several minutes, the warning lights cleared, and the steering wheel was no longer locked but felt loose and unstable ("wobbly"). I cautiously resumed driving. After several minutes, the steering began to feel normal again. The following warnings were displayed: Hill Start Assist problem, Trailer Stability Assist problem, Hill Descent Control problem, Adaptive Cruise Control problem, Lane Keeping Assist problem, Collision Mitigation Braking System problem, Road Departure Mitigation problem, Low Speed Braking Control problem, Auto High-Beam problem, Electric Power Steering system problem – Steering Assist Not Available, and "Stop. Steering assist reduced. Stop driving when safe." The failed component appears to be the Electric Power Steering system and related driver-assistance systems. The vehicle is available for inspection. The problem was previously addressed by a dealer but has reoccurred. No prior warning lights were present before this incident. The failure occurred suddenly while driving.

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.

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. 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.
