I was travelling northbound in the right lane, of two lanes, on Hwy 55 in St. Louis Tuesday around 0715 when my Honda Pilot suddenly braked very hard; the Collision Mitigation Braking System (CMBS) had gone off without reason. I was in a construction zone and I was probably traveling about 50 miles per hour. There were no barriers immediately in front of me, as in a hard curve left or right and definitely no vehicle in front of me and thankfully no vehicle behind me, considering the normal bumper-to-bumper morning traffic. I did not come to a complete stop, well I don't think I did, but slowed greatly enough that all vehicles on my left driving past me fairly fast. I was in shock and confused unable to figure out happened. After a brief assessment of my surrounding I accelerated and continued on my way to work. If someone has been following me I have no doubt they would have collided with me, worse it could have been a tractor trailer! I got to work and was mentally shot for the rest of the day. The dealer was friendly, somewhat empathetic and I scheduled a maintenance check up. I have owned the car less than one month of this this report. I am already looking for a new vehicle and will NEVER own a Honda again. Driving this vehicle with that CMBS that can go off randomly, a/k/a "phantom brake" is nerve raking. I do my best to remember disable the system before driving. Sadly, a system I would ordinarily enjoy having. Also, I now fear following other Honda drivers because if their CMBS fail I might crash into them! The idea Honda has not repaired this or a recalled their vehicles is mind bending; this could cause fatalities! Frankly, their complacency is nothing short of apathy for human life. I am going to lose thousands of dollars getting out of this vehicle, which I find unacceptable and cruel. I am happy to testify to this account and am telling you this is nothing short of my sworn statement.

Vehicle collision system for warning distance was placed to low setting. Driving about 30mph with no cars in front but a large dually on my left lane and a truck on my right lane, similar speed or slightly less, all of us 3 approaching an under construction intersection. Neither car came in my lane yet my system warned me to break and then activated the brakes forcefully. Rear passenger witnessed also and agreed they saw no cause to trigger sudden breaking. No car behind me or else we would have been rear ended. Tried turning system completely off but it resets every time at car startup.

Subject: Safety Complaint Regarding Adaptive Cruise Control Malfunction – 2025 Honda Pilot Dear NHTSA Office of Defects Investigation, I am filing a formal complaint regarding a recurring safety issue with my 2025 Honda Pilot, which I purchased in September 2024. The vehicle’s Adaptive Cruise Control (ACC) system frequently and unexpectedly turns off while driving on the highway, creating a serious road safety hazard. This issue has been happening intermittently since I bought the vehicle, and despite bringing it to Honda’s attention, they have not acknowledged or addressed the problem. The sudden deactivation of the ACC system can cause unexpected speed changes, forcing the driver to react quickly and potentially leading to hazardous driving conditions. Given the increasing reliance on driver-assist technologies, such malfunctions pose a risk to both the driver and other motorists on the road. I have reported this issue to my local Honda dealership, but they have not provided a permanent resolution. I am concerned that other Honda Pilot owners may be experiencing the same problem, which could indicate a widespread defect. Therefore, I urge the NHTSA to investigate this matter thoroughly and take appropriate action, including issuing a recall if necessary, to prevent potential accidents. Please confirm receipt of this complaint and inform me of any next steps. I am available to provide further details or documentation as needed. I appreciate your prompt attention to this critical safety concern. I also attached photos of the said issue. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2025 Honda Pilot. The contact stated that while driving 74 MPH, the vehicle unintendedly decelerated to 50 MPH. The message "Front Driver's Assist System Cannot Operate - Clean Area Some" was displayed. The contact stated while in the process of pulling over to the side of the road, the vehicle accelerated as needed. The contact was able to continue driving. The vehicle was taken to the dealer, where it was diagnosed that the front radar had gone into LIMP mode and was misaligned. The dealer realigned the radar. Additionally, the dealer informed the contact that it was a known failure and that the front radar of the vehicle could become misaligned after hitting a pothole. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 1,172.

When we have taken this vehicle on the highway or interstate, the Adaptive Cruise Control randomly disengages while driving and renders any cruise options unusable. When this happens the vehicle brakes hard while driving. The braking system also randomly brakes hard while driving, even if the cruise control is working. This is a huge safety concern as we are on the highway and interstate with several other vehicles around us. We are worried we will get in an impact collision from the rear. We have taken this vehicle to a certified Honda repair center four times for this specific concern and this 4th occurrence, the Pilot has been there for over 27 days with no resolution. This is a brand new vehicle and we have had this safety issue/faulty ACC since we purchased it.

The driver will get a caution alert on the dash that says "some" safety features "May" be disabled. However, there is no information about which ones or why. This particular issue has happened multiple times in inclement weather. Also I know it's a problem as while in the dealership many were calling asking g about why this was happening. It is a danger to drivers. If they heated the "H" emblem, where the radar sensor is, it would not be a problem.

My brand new 2025 Honda Pilot frequently (several times per week) will deploy the CMBS (Collision Mitigation Braking System) causing the brakes to be applied harshly and bringing the vehicle to a near stop, despite there being nothing in the road ahead, behind, or to the sides of the vehicle. This happened the first time with only 100 miles on the vehicle. My concern for safety is that sudden unexpected braking could cause an accident and lead to potential injury/death. I've had the vehicle to the dealership 5 times and they've had a handful of excuses. First the alignment of the car was off. Next was a replacement of the radar unit, which they believed to be faulty. The next visits resulted in my Honda tech telling me that a "large radio tower" near where I live are causing interference with the system. However when I received the paper work it says there are large power lines causing interference. I live in a small town and there are no large power lines or large radio towers visible from where I live. I believe Honda is making excuses to get me to stop bothering them with this issue. After all of these trips, Honda is refusing to look at the vehicle again, despite it's behavior putting myself and my family at risk. There were no warning lamps, messages, or anything other symptoms prior to this happening.

As you can understand, there is no effective way to stop this safety defect from reoccurring. The solution may be an encrypted design for the sensor, that only works on the car it was installed on. Police report cannot be made until we know the accurate repair cost.

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.
