general problems of the 2025 Honda Civic

“collision mitigation system problem see dealer” warning! once at unknown mileage around 6,000 and once at around 10,000 miles. Random vehicle braking around 6-8 times in 12,000 miles with no reason. Braking happens while in cruise control. Both times that the warning messages appeared it was along with warnings for adaptive cruise control, automatic braking, lane departure, lane keep assisting. Many warnings all flashed consecutively with the final warning about collision mitigation system problem see dealer.

While driving on the highway, I attempted to accelerate to safely merge into an adjacent lane when the accelerator pedal became stuck in the fully depressed position. The vehicle continued accelerating and the pedal would not release. I applied the brakes and exited the highway at the nearest exit, brought the vehicle to a complete stop, placed it in park, and turned the engine off. After restarting the vehicle, the accelerator pedal remained stuck. I had to manually pry the pedal up from the floor. There were no loose objects or aftermarket floor mats present—only properly installed Honda factory floor mats. This appeared to be a mechanical failure and presented a serious safety risk.

On a two way lane highway, vehicle detects on coming traffic and causes sudden deceleration of vehicle and braking which can cause being rear ended by another vehicle. This also occurs on multi lane freeways when going in the same direction the vehicle will detect a vehicle in the lane next to me braking and again cause the vehicle to decelerate and brake which could cause an accident. Occurs at least once or twice a week. I have a video of the issue which might be better.

The vehicle unexpectedly began accelerating from a creep with no accelerator input. Acceleration ceased immediately as soon a the brake pedal was touched. No actual braking was required--simply a touch on the pedal. Acceleration was as if the accelerator pedal had been pressed about 1/4 down. It lasted about 1. 5 seconds from initiation to touching the brake pedal. The pavement was not on a grade but was substantially level. This is the 3rd or 4th such incident in the last few months. In the other incidents I was unsure if it was my imagination or some unrelated factor like grade. In previous incidents I had been about to accelerate in any case, and pressing the accelerator overtook it. In this incident, the car was navigating a parking lot, having just pulled out of the parking space and moved 50-100 ft. The car was moving in "creep" mode, I. E. , the ev system simulating the creep of an automatic transmission (CA 0-4 mph). My impression is that each incident occured not long after restarting the car, though I am not fully certain of this. In this occurence there was one passenger; in all previous occurences there was no passengers. In all occurences, the cruise control system was on but not engaged. The "driving style" was set for normal, as opposed to sport or eco. No alerts or unexpected lights were observed on the instrument panel. For the latest incident, the driver's floor mat was checked and found to be properly secured and well clear of the accelerator pedal. The car's last (and only) service was the normal Honda "a1" maintenance in may 2025 at ~11000 miles. Service was done at a Honda shop, so any firmware should be current to that date. The shop was not notified of the acceleration issue at that time. The Honda shop has been notified today (July 5).
