Filed Aug 5, 2026 · Driver assistance · TX

while driving last week with my family, doing some grocery shopping, we got on the highway which is 75mph in our 2021 Honda Civic and it had a catastrophic failure on its ADAS system out of nowhere it stopped and made my car swerve off the road and applied the breaks like it detected a car in front of us, it took us from 75 to 0 pretty darn fast fortunately no one was behind us, after the event im not able to use any features that involve the camera which includes crucial features of the car including cruise control, i can't even see what any info that is supposed to be displayed on the dash, I took it to the dealership where they said that their ADAS system doing this's a common occurrence and that most likely the camera it self will need replacement, i truly believe this to be a very dangerous feature that should be looked into and if the camera is prone to getting messed up like they said they are there should be a recall on this equipment before there's a bad accident! also yes my vehicle is and can be inspected whenever it is needed and no we didn't have any problems whatsoever with the ADAS system before it just failed

Cruise control does not disengage upon electronic parking brake being engaged while moving, causing the car to accelerate aggressively after the brake is released. While it does disengage after enough speed is lost, it should disengage immediately as it does when the brake pedal is tapped

The Steering Gearbox, Electronic Power Steering failed. The steering was resistant and sticks on the highway, causing jerking and overcorrection to control the vehicle. This was with both manual driving and Lane Assist. Took the vehicle to the local Honda dealership, they confirmed the problem, and replaced the steering gearbox, EPS, because it was still under warranty. However, this is the same exact part and this problem will occur again. The car did not display any warnings.

On multiple occasions my car has applied the brake while driving on the highway as well as my caliper has become frozen and I have replaced brakes 3 times in less than one calendar year. I have all old brakes that have needed to be replaced and there is uneven wear on them.

I have had dozens of incidents where I will be driving down the road and my car will just break for no apparent reason. It is totally random and at times terrifying. It happens with no other vehicles in front of my vehicle as well as while I am just driving in traffic with cars behind me. Many times, after it happens initially, I cannot accelerate the car due to the breaks locking up. I have to put the car in park and then drive to accelerate. I have asked my service providers at HONDA the dealership about this, and they have no idea why this is happening. This is so dangerous and frightening.
