2020 Honda Civic

on 7-28-26 After filling my vehicle with gas at the next red light, all lights on dashboard went on flickering warning (Christmas tree effect). on 7-29-26 After researching online Roadside came out and did Battery and alternator test that passed. I did hard reboot from instructions I found online and after several attempts the lights cleared twice, the morning of 7-30-26 when leaving for work the flickering lights came back on. Vehicle had a slight tremble but cleared after a few seconds while vehicle warmed up. I went to get the battery checked at the shop and it passed also had air filter changed. Lights still on, car is running fine, but I feel unsafe to drive and have an appt at the dealer for a diagnosis check on 7-31-26.

At least a half dozen times the car would brake automatically when nothing was in front of the car. The BRAKE warning light would appear on the dashboard as the car abruptly slowed down. The car slowed down but never came to a complete stop. This happened at various speeds. Once on the freeway at high speeds, 3 times just before an intersection where I had a green light and other various times. I brought the car to 2 different dealers. They could not replicate the problem so they said there was nothing they could do. The courtesy car driver who gave me a ride said they occasionally experience the same thing in the courtesy car.

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.

My automatic Breaks that prevents me from rear ending a car keeps engaging when I am a few car lengths from another vehicle. It’s happened once yesterday and once today. Both times in heavy traffic areas. I’ve had the car for two years and this is the first time this has happened. Thankfully no one was following close behind because they may have hit me. I’m afraid this is going to happen one day when someone is too close and I’m going to get rear ended. It’s really scary and dangerous. I’m scared to drive my car.

The vehicle’s emergency braking system randomly applies the brakes even when the front is not obstructed. Front sensors are kept clear of any debris, dirt, or bugs. I went to Honda of El Cajon in El Cajon, Ca and they could not help me even though the service advisor admitted that another Honda CR-V driver had the same problem the same day. This is a safety concern as my car has applied he brakes while on the freeway and at stop signs at random. Honda has failed to acknowledge the issue.

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.

Gas door opens randomly and it’s happened more than a few times now which is becoming a safety hazard especially because I drive 80 miles daily for work. Also my automatic brake senor is a hazard because it’s going off when cars or objects are farther away; which leads to the 3rd issue with my seat belts which is either to tight on the chest area and possibly choking me when the car automatically brakes when objects aren’t near or in close distance to my car
