On three occasions, my car has not started as expected. Twice I was at busy intersections at a stop, and when I started to go, the car shut off and would not allow me to restart the engine. The third time I had not been driving and was in a parking lot, trying to start the car to leave and it also would not start. When this happens, the brake locks, the steering locks, but the lights are still on around the center console. The start stop button goes black and refuses to work on all three occasions. I have had to wait and try again and try again and try again before the car will restart and allow me to drive again. Then all of the panic alerts flash on the dash and cycle over and over and over telling me to see the dealer also saying there is a brake system problem. I do have a video of these, but my video is too large to attach here. This is very dangerous being stuck in an intersection with cars all around not being able to move. I took the car into the dealer today and they wanted to tell me that my battery was having interference or corrosion. The car is only one year old. They also said that the idle start stop was draining amperage from the battery perhaps keeping it from restarting if I were making short trips or in heavy traffic. Either way, this is a huge problem and safety concern on my part. I am paying for a brand new car that I feel is unsafe. They did not share with me that there is an active investigation about this very issue. I feel they were not very transparent with me. Down below, I will attach an image of what the dealer said about the issue when I visited them today.

Vehicle has many fault codes that will not clear. Took to dealership and the state they believe its a wheel speed sensor and vehicle is safe to drive. Flashing warnings include AWD system problem, electric parking brake problem, brake system problem, brake hold system problem, electric power steering problem, antilock brake system problem, vehicle stability assist problem, hill start assist problem, trailer stability assist problem, hill descent control system problem, adaptive cruise control problem, lane keep assist problem, collision mitigation system problem, road departure mitigation system problem, low speed braking problem, auto high beam problem, parking sensor problem, antilock brake system problem, as well as drive mode change unavailable, rear hatch will not open, drivers seat will not automatically move into position once vehicle is started, vehicle will not shut off without having to hit the off button numerous times, and vehicle is not auto shutting off after the 10-15 min timeframe. Dealer states they have ordered the part and is currently on back order. Was told Honda does not provide loaner vehicles for warranty work. Seems strange that a wheel sensor could cause so many errors and shut off all safety features, brakes and drivetrain of the vehicle.

Rattling noise when using heater. Seems to happen when the car is cold and fan speed doesn't seem to change it much. Once the car is warmed up it mostly disappears.

1) 2024 Honda Pilot is a 7 passenger vehicle w/2WD towing rating of 3500 pounds.With 4 people in the rows 1&2, and 4-20 lb. suitcases in the cargo area behind the 2nd row, the rear suspension has extreme negative camber on the suspension and it looks like it's weighted down with a ton of rocks in the back.This causes excessive tire wear on the inside of the rear tires.I brought this into the dealership to address, and they said that it's normal.They declined to check the alignment specs, and said that they just put a couple guys in the 2nd row and all looked normal.Must be inaccurate specs, or it has inadequate rear suspension and/or rear shocks.Why would a vehicle with 60% of the passenger/weight capacity, and with not even set up with a towing hitch, have this kind of problem?This should be investigated as we've never had this problem with our previous Honda's, or any other vehicle. 2) Since new, we have problems with the acceleration of the vehicle, primarily from a standing start.When we try to gently press on the gas peddle it surges forward like a person in a sports car trying to spin the tires.This has nothing to do with the pavement as it's dry concrete, and it is very hard to get the vehicle to move forward without spinning the front tires.Dealership says that it's normal as it just has to do with the gearing of the new 10 speed transmission and it's sensitive (huge understatement).This rapid acceleration is dangerous and can cause you to loose control, and even worse if we're driving on wet roads.I've never experienced a gas peddle/acceleration problem like this on any vehicle I've owned in 40 years, even sports cars.Drive one of these Pilot's and you'll see yourself! 3) Honda's Vehicle Data Privacy Notice is extremely unethical and should be illegal.Honda is collecting and selling it's clients personal info to third parties. They're trapping clients and compromising personal data and identity for even more money.This leads to identity theft.

Just returned back home from a quick drive and the vehicle was sitting in my driveway. After about 20 min I walked by the car and noticed the entire back window in multiple pieces. There was no one that walked by or drove by. Pieces of glass were noted to be 10 feet behind the vehicle on the driveway. There was no one in the vehicle at the time and nothing in the trunk area that was potentially pressing on the glass. Vehicle was towed to the dealership where it was collision wrapped until the glass could be replaced.

I purchased a 2024 Honda Pilot on [XXX]. In March, between the 4th & 22nd (approx 1800 mi) I thought I saw a crack but as my vehicle had been parked in the parking structure where I live adjacent the ports of LB & LA (prone to excessive dust) & recent rain/moisture causing the dust to form into lines I figured to wait until washing before confirming. On 3/22 I confirmed a crack - no point of impact. As I had planned a vacation to Mexico I opted to photograph the crack AND the vehicle in Mexico capturing date and location stamp. I returned on 4/16. On 4/29 I took my vehicle to El Monte Honda. I let the service advisor know about the crack & upon inspection he found a 2nd crack - no point of impact. The advisor said they were scratches on the inside - 2 piece laminated. I pushed back because the visible thickness of the crack I discovered did not match the hairline feel. He convinced me that replacing the windshield could lead to other issues such as leakage - a known problem on the current generation so I asked him to note the damage - he noted a scratch. I took the vehicle but ultimately decided it wasn't fair as both were in drivers line of sight. Upon return he said the system used to communicate between the dealership and manufacturer was down and would have to come back. I called 2 months later - no return call. 9/13/24 I decide to go to local dealer (Long Beach Honda). The service advisor inspected and said he would call Honda but did not. Driving away I noted a smudge where the advisor located a crack - a 3rd crack, no point of impact. Called Honda & they said no record of me going to the dealer. Closed case. On 10/1 I returned to LB Honda with a record from 4/29 and images. He said possible glass delamination but only because a Boeing engineer reenforced stress cracks. He did not return calls nor advise Honda. Called Honda. They refuse to do anything without a diagnosis and service advisors are running away in what appears a deliberate effort.

The vehicle was purchased brand new on Feb 1st 2024. While driving on the highway on Feb 5th 2024, with only 105 miles on the odometer, and no prior warning messages/lights, many warning messages were suddenly displayed on the dashboard, repeating one after the other, instructing that various safety features were disabled, displaying: "Parking brake not available", "Brake system problem", "Brake performance may be reduced", "Brake hold system problem", "Anti-lock brake system problem", "Vehicle stability assist system problem", "Reduced traction and handling", "Electric power steering system problem. Steering assist reduced", "Hill start assist problem. Vehicle may roll upon brake release", "Trailer stability assist system problem", "Hill descent control system problem", "Adaptive cruise control system problem", "Lane keeping assist system problem", "Collision mitigation braking system problem", "Road departure mitigation system problem", "Low speed braking system control problem", "Auto high beam problem", "Parking sensor problem". In addition, after coming to a full stop and shifting to Park, (or, turning off the car) the tailgate would not open regardless of how we tried (dash button, remote key, tailgate handle, foot swing). Also, the car would not turn off after pressing the On/Off button. The button would need to be pressed repeatedly to turn off the vehicle. All of these safety systems and functions were disabled at the same time without prior warning while driving at highway speeds. The Honda dealer confirmed the problem, inspected the vehicle, and concluded a faulty ABS control module is to blame. We know of one other 2024 Honda Pilot owner in our neighborhood who experienced the same issue, which makes it likely that this is a common problem. Honda should have designed redundancies to prevent sudden simultaneous failure of so many safety systems. Honda should recall all affected vehicles to replace faulty ABS control modules before people are hurt.

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.

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.
