The contact owns a 2023 Honda Pilot. The contact stated that while driving at an undisclosed speed, the stability, traction control, ABS, brakes, Lane Departure, and speedometer warning lights were illuminated. The "Anti-lock Brake System, Brake Performance Reduced", "Parking Sensor Failure", "All-Wheel Drive System Failure", "Electric Power Steering System Failure - Steering Assist Reduced", and "Vehicle Stability Assist System Failure - Reduced Traction and Handling" messages were displayed. The vehicle was taken to the dealer, where it was diagnosed that the sensor assembly front (57450-T90-A02) needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 9,100.

Honda Pilot 2023 Elite shows 15+ error messages on the instrument panel. Messages indicate emissions systems, breaking systems, power steering and various risk mitigation systems experiencing problems resulting in reduced performance. Errors show up when the vehicle starts and are easy to reproduce. Dealer has looked at the vehicle 3 separate times. Problem occurs again in few days after dealer visit. Dealer based on the system error code diagnosed the problem with the fuel system. So far the dealer has replaced the high pressure fuel pump, injector relay, fuel pressure regulator and fuel rail pressure sensor. Dealer says when the vehicle starts the problem with the fuel system causes the electrical/computer system to go in safety mode; this makes onboard computers believe all systems are failing. Dealers' attempts (in consultation with manufacturer support) have so far not resulted in successful resolution of the problem. Without taking undue risk, I have personally tested some of the safety systems in errors indicated on the cluster panel to actually not work, e.g. lane departure mitigation system. Importantly, it feels vehicles braking distance has increased and steering is harder compared to when vehicles had no issues. All errors that are displayed are listed below. 1. Emission system problem, 2. Break system problem, 3. Electric parking brake system problem, 4. Break hold system problem, 5. Electric power steering problem, 6. Trailer stability problem, 7. Adaptive cruise control system problem, 8. Road departure mitigation system problem, 9. Vehicle stability assist system problem, 10. Hill start assist problem, 11. Trailer stability assist problem, 12. Hill descent control system problem, 13. Collision mitigation breaking system problem, 14. Road departure mitigation system problem, 15. Low speed breaking control problem.

At 850 miles on the odometer, the 2023 Honda Pilot ECU failed during normal operation of the vehicle on local roads, leading to a loss of power to engine transmission components, emissions systems, brake hold system, and traction control leading to reduced control and speed over the vehicle. The vehicle has been sent to the dealer for inspection of the OBD warning messages displayed. The driver was unable to operate the vehicle due to impaired speed, acceleration and braking capabilities that accompanied the ECU malfunction. The problem is currently being diagnosed by the dealer at the Keating Honda Service Center in Conroe, TX. The warning messages which appeared included the following while experiencing the ECU failure: Emissions System Problem. Avoid Heavy Acceleration and High Speed.

The vehicle was purchased 7/1/2023. It is a 2023 Honda Pilot. 8 days after the purchase (OD mileage: 332), on a major highway, all mechanical systems in the vehicle failed within 2 minutes of each other. The engine, brakes, electrical, airbags, AWD, all of the ADAS systems, etc. ALL lit up within about 5 minutes of each other. Soon after this happened, the vehicle essentially shut down and was forced to a stop in a turning lane off of the major highway. The vehicle gave no indication that this was coming. The dealership's immediate response was to assume that we had put diesel fuel in the vehicle (this was not the case). As of now, they still have not been able to determine the cause of these catastrophic failures. Completely unsafe! This failure event could have been lethal and no one has any answers...

No cars, pedestrians , nothing. Just my pilot. The speed limit is about 45MPH and it will slam the breaks on. It has become so problematic I avoid traveling that direction on my road. It has happened to my spouse while driving as well. And again, it’s not every time, but sometimes. It has happened about 10+ times. Makes me nervous that while driving it will do it, and I will be rear ended.

The pilot sometimes hesitates when trying to accelerate in normal mode (have not used in other modes). It happens randomly, and the same when trying to slow. It seems the transmission is not shifting properly. Or something is preventing it from transitioning properly.

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.
