The vehicle came to a complete stop while attempting to enter the Highway. As I accelerated to gain speed, and the vehicle halted down to stop, all sensor warning systems started to light up on the dashboard: Adaptive Cruise Control, Automatic Emergency braking, Lane Departure Warning, Parking Collision Warning, Lane Keeping Assistance -- all sensors flashing simultaneously. As our vehicle stopped, the vehicles around us in the Highway had to abruptly stopped as well, causing a serious hazard, not only to myself and my family, but also the potential for a serious injury to other as well. This incident happened to us twice, and my passenger was able to record a video of the dashboard, as all the sensors were flashing and the vehicle switch to neutral on its own coming to a stop. We explained to the Honda dealership service department and after the second time, they kept the vehicle for service and it has been over (30) days since we had any update. The vehicle has been inspected by the dealership, and it is still there as parts are in back order, but there are not sure of what the real problem is. There were no previous warnings of this problem, the vehicle is a 2024 Honda Pilot Elite with 30,174 miles, and still under dealer warranty. This is the 3rd Honda Pilot I ever owned and never experienced anything like this before. My biggest concern is that if they do not fix this vehicle properly or if it is defective, my life and my family's will be in danger every time we drive it, as we do not know when it will decide to stop while driving.

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.

The vehicle is extremely slow to accelerate at low speeds under 20mph. There have been several near accidents due to the lack of acceleration. The recall for the fuel injector was addressed and ECM per manufacture but hasn’t solved the problem. This is dangerous for any acceleration that can cause you to get hit.

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.

I hope this message finds you well. I am writing to express my deep concern regarding the ongoing safety issues with my leased Honda, which I obtained in March 2024. Shortly after leasing the vehicle, I noticed that the sensors would frequently activate and deactivate without any apparent reason. In May 2024, while driving, all the sensors turned on, deactivating all safety features and causing the car to swerve. The sensor lights remained on the next day, prompting me to take the car to the dealership. I was informed that the sensor and a camera required repairs, which were subsequently addressed. Despite my concerns about the safety of driving this car, especially with three children, I was assured that the issue was resolved. I filed a complaint with Honda Corporate, and they indicated that the issue would need to recur 2-3 times before considering a different vehicle. Unfortunately, on [XXX], all the sensors activated again while I was driving, causing the car to stop accelerating in the middle of a busy road with my children in the back seat. This placed us in a life-threatening situation, as other vehicles were traveling at high speeds. The transmission light also turned on, advising to avoid high speeds. The next morning, I reported the issue to Honda and arranged for roadside assistance to tow the car to the dealership. During the towing process, the sensors activated again, and the car struggled to accelerate. Once at the dealership, I provided videos of the car's behavior to Ricardo, the service advisor, who acknowledged the severity of the issue. However, he later informed me that the sensors were not currently active, and the scanner could not detect any issues. Despite keeping the car overnight for further testing, they were unable to identify or repair the problem. I was advised to either pick up the car or leave it with them, but no loaner vehicle was offered. I am extremely concerned about the safety of driving this car.

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.

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.

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.
