The collision mitigation breaking system has wrongly engaged the breaking system on two occasions since I have purchased the car in September 2025. The car is available for inspection. Both times, the car hard braked when turning right at stop sign. The second occurrence, today, 5/15/26 the car also honked. I plan to call the dealer tomorrow report the issue but from what I have read so far this is a known issue with no resolution and is not easy to replicate, therefore I am filing this complaint to document the issue. Both times this was very alarming for me. Today, there was another person at the stop sigh to my right and a pedestrian a bit a way when the car slammed to a halt and honked, alarming me and probably them as well. There was no warning or alert, the car just halted.

There are three dangerous systems in my 2025 Honda Pilot EX-L that should be permanently disabled or removed by the manufacturer or dealer. In order of danger; (1) Collision Mitigation Braking System, (2) Auto Idle Stop, and (3) Road Departure Mitigation System. All three of these systems have nearly caused wrecks for me several times. The Collision Mitigation Braking System (1) is especially dangerous for rear-end collisions to the vehicle using CMBS. Example, I was driving in heavy traffic in the middle lane on I-40 near Hermitage, Tennessee on 23 Apr 2026 with adequate distance between me and the car in front of me. A tractor-trailer was close behind me. Suddenly, a car in the lane to my right moved into the gap in my lane between me and the car that was at a safe distance in front of me. The CMBS activated and started braking the car. I pressed the gas pedal hard to try and maintain my 70 MPH speed to no avail. The tractor-trailer swerved into the lane to my left missing the rear of my car by inches, and avoiding a massive chain reaction collision of many cars. This was a near fatal event for me. Without CMBS, I would have simply held my speed steady until I could create a safe distance and ease into a safer position, possibly in the lane to my right, a much less eventful situation. The Auto Idle Stop (2) has a knack for shutting off the engine when I am trying to make a left turn in heavy traffic. After several near misses, I have learned to turn this system off when starting the engine (the default is on). The Road Departure Mitigation System (3) shakes the steering wheel if the system thinks you are moving out of your lane. It shakes the steering wheel to alert you. Twice, I was caught by surprise and overcorrected the steering when the Road Departure Mitigation System started shaking the steering wheel. So instead of staying in my lane, this almost caused me to go out of my lane and possibly collide with another car or a road barrier.

I pressed my brakes down for the car to stop. It did not stop. The car kept going/rolling My husband the passenger told me to STOP. I heard him plainly say. I told him I am stopping. But the car would not stop. It kept going and rolling into a brick building at the end of the parking space. We braced ourselves. What else do you do when your car won’t stop I was probably goingb8 mph. Nothing fast. Not on the phone. 75 degree perfect weather in [XXX] I’ve had this car about five months. No problem at all until this incident never in my life had I ever had brakes to fail me. Well the brakes failed. Technology is built by men and programmed by men. I am a nine car Honda owner. This car has a brake technology problem. With all the technology, it should have stopped on its own. It didn’t. When brakes are applied technology should work. In this case technology failed. This car has a brake defect technology problem. Brakes were applied a car doesn’t have to have a recall on it for it not to have a technology problem. These cars are not perfect. Programmed and built by human hands. ImnsurevifvMr. Soichiro Honda sat down with me and did this problem with one of his cars.. he would surely say” I’m sorry that happened to you” I’m sorry you’re brakes did not work and they did not . American Honda needs to recognize accountability. I wish they would experience what I experienced. It would be a scary situation that is if you survived yrs, I’m sure if it happened to them. No car is perfect. This one sure isn’t. I no longer am an owner of this 2025 Honda Pilot. Death trap it’s gone to somebody else.

Vehicle: 2026 Honda Pilot – Mileage 20,847 Issue: Engine Failure, oil leaks, wheel alignment, air conditioning, major gas leaks from the engine, safety electronics alerts on front dash display are saying the vehicle is not safe to drive. History of issues: 03-11-2026: Car broke down while driving in [XXX] . 03-12-2026: Received call from Ira Honda service and was told they needed to replace the engine. 04-04-2026: I was told the vehicle was ready to be picked up. I started driving home and found the vehicle was all over the road. I returned to Ira Honda and once again was given a loaner. Also, the engine was leaking oil. 04-09-2026: Ira Honda called and said one of the engine gaskets was defective and they needed to replace it. They said that now the alignment was back in spec. I was told that the 3 yr engine warranty begins anew. When I got home I looked more closely at the alignment document and saw that the alignment was still slightly out of spec. I called and was told that it was the best they could do. 04-10-2026: air conditioning not working and asked for them to fix the alignment. 04-13-2026: I again brought the vehicle in for service. But was told there were no loaners available. I arrived at 9:30am and at 1:00pm. The A/C was fixed and determined the frame was not set correctly when they replaced the engine. This was the reason the alignment was off by so much. So the alignment was fixed. 04-14-2026: Leaking oil. So again, I had to return to Ira Honda. No loaner was available. 04-18-2024: Saturday morning and we smelled gas in the garage. Started the car and it took about a minute to start. Asked if it was safe to drive, Ira service said yes. 04-20-2026: Started the vehicle up and same issue occurred. However, this time gas was leaking out. It leaked in our garage, on our driveway and all over the street. Again fixed. 04-29-2026: Car again failed to start. During startup the car leaked a large amount of gas. It is still at the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

The vehicle is experiencing persistent dashboard warnings including "Brake performance may be reduced," "Low Speed Braking Control problem," and "Parking sensor problem." These issues have been presented to your authorized dealer, Napleton Honda in Morton Grove, on three separate occasions with no resolution: September 29, 2025: I arrived at the dealer bay with active warning lights. The service writer instructed me to simply restart the vehicle to clear the lights. I have photographic evidence of the warnings from this date. October 25, 2025: The vehicle was brought in for repair. I provided cell phone photos of the active dashboard warnings, yet the dealer reported "nothing found." April 20, 2026: The vehicle was again brought in for the same issues. I again provided cell phone photos as proof of the defect, but the dealer reported "nothing found." Despite the dealer's inability to diagnose the cause, my photographic documentation from 9/29/25, 10/25/25, 4/20/26, and 4/25/26 proves these defects are real, recurring, and significantly impair the safety and value of the vehicle.

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.
