2020 Honda Civic Driver Assist & ADAS Problems

The collision mitigation braking system consistently detects objects in the road and forcibly brakes when the road ahead of me is completely empty. This has happened 4 or 5 times just in the last year. The first time it happened I was driving on a completely empty road when the CMBS activated and kept slamming on the brakes until I pulled over and restarted the entire car. I don't always have to restart the car every time, but if it ever happens on a busy road it will cause an accident. The dealership refuses to inspect the system or try to recreate the problem despite the fact that there was a class-action suit against Honda for this exact CMBS malfunction in several other models. They just tell me to manually turn it off every time I get in the car. I am human and sometimes I forget, so this is not a solution. I'm afraid that this buggy "safety" system is going to get me and my child killed one of these days. I am happy to have the system inspected, but it doesn't keep a log of every time it activates so there's no real way to verify the false positives, and it happens randomly so it's very hard to recreate.

Phantom braking. Really dangerous

ALL SAFTY LIGHTS APPEAR ON DASHBOARD. SAFTY FUNCTIONS NOT ENABLED.

Phantom braking, has occurred over a dozen times. Caused me to spill hot coffee all over my face and neck causing mild burns.

WHEN RIDING DOWN THE HIGHWAY AT THE SPEED OF 70 MPH THE CAR SLAMMED ON BRAKES ALL BY ITSELF, ALMOST CAME TO A STOP AND THEN EVERYTHING WENT BACK TO NORMAL . i AM AVAILABLE FOR INSPECTION OF THE CAR. MY GRANDAUGHTER AND I WERE IN THE CAR AND IT WAS A VERY SCARY ORDEAL AS THE CAR WAS TRYING TO OR DID SLAM ON BRAKES. THE PROBLM HAS NOT BEEN REPRODUCED OR CONFIRMED BY A DEALER, HOW COULD IT? HAS NOT BEEN INSPECTED NO WARNING LAMPS, MESSAGES, SYMPTOMS, NOTHING OF THE SORT

Warning light appeared on dashboard for obstructed radar sensor. Sensor was not obstructed. This was followed by additional warning lights that safety systems were malfunctioning, ACC, collision warning, automatic emergency braking systems are offline. Reported to local dealer.

The automated emergency braking system activated bringing me to a sudden and complete stop. I was traveling at a lower speed (<20mph) with sufficient space both in front and behind my vehicle which prevented this incident from becoming an accident. This occurred at night. The braking system automatically engaged as I was releasing my foot from the gas pedal to coast. Should this happen at higher speeds or with traffic closer behind me, an accident could have happened. The system has not been inspected as of now and has not been reproduced or occurred a second time. There have not been any warning lights, messages, or other issues with the car since I bought it brand new.

The contact owns a 2020 Honda Civic. The contact stated that while driving at 60 MPH, the vehicle ahead of him attempted to make a right turn. Although his vehicle was at a safe distance from the vehicle ahead, the Forward Collision-Avoidance feature independently engaged, and the warning light illuminated on the instrument panel. The contact stated that the feature did not recognize that the vehicle was making a turn and that the abrupt stoppage could have caused a rear-end collision with the vehicle behind him. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 12,300.

On multiple occasions, the collision mitigation braking system has had false-positive detections. There is one section of road where this occurs extremely frequently (maybe 20% of the time I drive through). On this section of road, it will not activate the brakes, it only beeps and displays "BRAKE" on the instrument cluster, but is extremely disconcerting and distracting. On another occasion on a different road, there was clear road ahead of me when the collision mitigation braking system had a false detection, and did activate the brakes and was incredibly close to causing a collision with a car driving behind me. On this same stretch of road, Ive had this occur two other times (out of hundreds I've driven on it), but no one was behind me and would not have caused an accident. In both of these spots, the road is fairly straight and the speed limit is 40 MPH. This hasn't been inspected by a dealer. This hasn't been inspected by Honda, the police, or insurance. There were no prior warnings to this issue occurring.

Breaking mitigation or control system was defective, seat belt didn't work properly and involuntary breaking led to incident in which face hit the steering wheel, leading to injury. The problems were evaluated by the dealership but they denied there were problems, and there were not other parties that evaluated the car. There were some warning lights that came on several weeks in advance of the involuntary breaking.

The automatic braking system for my car went off in the middle lane of a 3 lane highway. luckily there was no cars driving around me so i was not hit. It sensed something and dropped my speed from 55 to 20 in a couple seconds throwing me forward. If not for my seatbelt and my arms my face could have hit the steering wheel. This happened multiple times.

The contact owns a 2020 Honda Civic. The contact stated while driving at various speeds, the Forward Collision-Avoidance Automatic Emergency Braking erroneously activated causing the vehicle to abruptly stop. The contact indicated that the failure had occurred on eight separate occasions while driving between 5 and 65 MPH. The vehicle was taken to the local dealer however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 7,000.

The contact owns a 2020 Honda Civic. The contact stated while driving at various speeds, the lane departure assist steered the vehicle into traffic or over the lines randomly due to a possible object being in the roadway. The beeping sound, visual detection, and lane departure message were displayed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 120. The VIN was not available.

CMBS automatically and unexpectedly deploys for no reason: there is no car or obstacle in front of the car. This has happened multiple times. I have taken the car to the dealer twice with this complaint and they were unable to duplicate the issue, so I was told they couldn't find anything wrong. I now disable the system each and every time I start the car because if I don't, I foresee a circumstance when freeway driving that I would be severely rear-ended, causing me major injury, or even death.
