2018 Honda Civic: false forward collision warnings

Filed Jan 4, 2025 · Driver assistance, Engine · GA

March 5th 2020 I finally recorded a message that had been appearing in my dash board during late night drives. Message read as "Adaptive Cruise Control Problem" "Collision Mitigation System Problem" I notified Honda of North Hollywood service department at the time, and they said they could not do anything to fix the problem unless the message was actively displayed on the dash board during the time of service. Unfortunate for me the message would come and go and would not remain on for the service advisor to see. Several times my vehicle would randomly brake abruptly (to a screeching halt) due to a malfunction in detecting cars/objects around me. Luckily I managed to not crash or have other vehicles crash into my car from behind, but it scared me. I've always wondered what the issue was, and was never able to get it resolved because I didn't have proof of the abrupt stops. Fast forward to May 2024 I received a letter in the mail for a recall on the fuel pump module. I think this might have something to also do with not being able to start my car three times within one year... I ended up replacing multiple batteries and cleansing the fuel tank thinking that was the issue and I have been mobile since then. I have contacted Curry Honda in Georgia multiple times to get the recall resolved. 8 months since I received the recall notice, and the issue is still unresolved. Please help. I rely on this vehicle to get to work, and I am still paying on this car. I am concerned of the safety issue.

When driving, if the sunlight is just right casting shadows in front of the car from trees, or while traveling down a divided highway passing 18 wheelers (mainly in the evening), the shadow created causes a false alarm on the collision avoidance system causing it to react by hard deceleration. This is also accompanied by the audible BRAKE alert coming across the gauge cluster. While at highway speeds, it can really startle you and possibly cause you to be rear ended due to the sudden and Unneed braking. You have to get hard on the accelerator in order to overcome the computer trying to slow you down. There is a recall on OTHER Honda vehicles for this exact thing, and it needs to be expanded to the Civic as it suffers from the same problem. The approximate date section only contains 1 date, but yet it has happened numerous times.

I got the car with Honda Sensing to include adaptive cruise control, lane departure warning, and forward collision warning. All these systems stopped working within 36 month and under 36000 miles. Honda dealership wants more than $2500 for a fix that I read on the internet does not seems to solve the problem. Many people report that the problem is either not solved or it recurs within 6 months.

On 05.02.2021, I was driving our CAR in Philadelphia, and stopped at red light. When I started driving in heavy stop and go traffic knowing I had to stop in 200 ft. brakes failed, brake pedal went to the floor and the car accelerated, emergency brakes didn’t start and Forward collision warning didn’t work. I hit the car in front of me. My car was totaled, more cars were damaged. Two months before this accident I was driving on a crowded Philadelphia city street and when I put on the brakes exactly the same thing happened - brakes failed, car accelerated, emergency braking didn’t function, Forward collision warning didn’t work. I drove the car to the edge of sidewalk to stop it. Nobody got hurt but the front of the car was damaged. I took it to Honda to investigate the brake failure. First the dealer said they checked and there was nothing wrong we can take to car. Later Honda America told the dealer, the car is not safe and we can’t get it back until they send an expert to check. After the expert, service people at the dealership said the car was OK. The problem could be an unsecured floor mat that interfered with the brakes and that is why brakes failed. We asked why the emergence brakes didn’t work. They said “when you pushed the brake the computer has a message that brakes are pushed and emergency brakes don’t come on functioning”. We removed the moveable floor mat and asked for the expert report. They told me he didn’t write a report. Later when I confronted Honda America they said there was a written report but I did not have the right to see it. Honda America also refused any responsibility saying it was up to the insurance company and they were closing the report.I believe Honda America is not acting responsibly. HONDA should share the expert report after the first accident, should investigate what went wrong during the accident, should try to figure out why the brakes failed twice in the same way in a two months period but operated fine in between.

On june 21, 2019, owner of a 2018 honda civic 5 door hatchback grand touring was driving along a 4 lane divided highway in a 45 m.p.h. Zone. Speed was approximately 46 m.p.h. The collision mitigation braking system (cmbs) suddenly activated without there being a vehicle or person in front or to the immediate either side front of the car. The cmbs went directly into stage 3 activation out a possible 3 cmbs stages. These are: stage 1: visual and audible warning stage 2: visual and audible warning and light brake application stage 3: visual and audible warning and strong brake application this almost caused owners car to be rear ended by the vehicle traveling directly behind owners car due to the violent and strong application of the braking system in owners car. Remember, no cars to front or immediate front sides or a person in those positions either. The application of the cmbs caused an extremely dangerous situation that could have resulted in injury to the owner of the 2018 honda civic or the driver of the vehicle directly to the rear of owners' vehicle. Vehicle was taken to a local honda dealer to report this incident. Dealer states computer glitch in data system. No codes associated with this event were found. And a verbal statement from technician of 'these things happen'. Not very satisfactory answer when this incident could have caused an accident. Vehicle was brought to shop in conjunction with a hopefully separate issue that will be reported separately. The technician cleared all codes and test drove vehicle for 2 miles. Technician stated she could not duplicate problem and released car. Owner had to return to shop to have technician set the system so the cmbs could be manually deactivated again as when vehicle was brought into shop.
