Loss of All Wheel Drive function, car nearly stalls out while at highway speeds and on surface streets (loss of power and bucks hard). Warning message appears for AWD system advising no power. I am convinced that I got a lemon. This car is absolute trash. Daily occurrence with this problem.

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

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.

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...

The warnings appeared on my dash, and the steering wheel pulled the car back towards the bicyclists. 2nd incident: I was traveling on a country road, goin over a hill. The cameras must have lost sight of the lane markers, dash flashed the lane departure warning and the steering pulled the vehicle towards the oncoming lane. There was a motorcycle approaching & I steered the vehicle back to the appropriate lane position. 3rd incident: My husband was driving on a country road. A tractor and farm implement was approaching in the oncoming lane. My husband slowed down & moved to the right of his lane to give the tractor more room. The lane departure warning flashed & the steering pulled the vehicle back towards the tractor/implement. We returned to the dealership & had them shut this feature OFF.

- There is a clicking noise coming from the steering column area after the vehicle has been driven on the highway for approximately 15 minutes and the vehicle engine has been warmed up. The noise can be heard at low speeds, such as pulling up into a driveway, or turning the steering wheel while parked. - The vehicle is brand new with 2900 miles as of today and the clicking noise coming from the steering column can pose an unknown danger to those in the car and around the car. - The vehicle was brought in to the dealership for service inspection pertaining to the clicking noise and the issue was able to be duplicated and recorded. However, the issue is unresolved and the case is still open. - The dealership service department had the vehicle manufacturer engineer on the phone to aid in the troubleshooting. The troubleshooting recommendation by the engineer was to check if there is a similar clicking noise from another vehicle that is the same year, model, and trim level prior to further investigating; this has not started due to dealership inventory unavailability of the same exact year, model, and trim level. Until the dealership receives the same year, model, and trim level to compare with, the case will remain open. - The issue was first noticed when the vehicle had approximately 2000 miles.

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. 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.
