2019 Honda Civic: false forward collision warnings

Filed Jun 11, 2024 · Brakes, Driver assistance · CA

I was stopped at a red light in the left-hand turn lane, waiting to turn left. Light turned green and I accelerated turning left. The car suddenly braked with no car or obstruction in my path. No collision mitigation light warnings came on. The car just slammed on the breaks!! Dealer service manager told me over the phone that unless a code comes up, they really can’t diagnose the issue. I believe this is a design flaw and not an issue with my car that can be addressed by the dealer. I have done research online and found many people reporting this issue and several while turning left. I am very concerned with the safety of this car.

I took my 2019 Honda Civic into the dealership because I got a warning signal that says, collision mitigation system problem. The dealership says it needs a part that is back ordered and told me I could drive vehicle until part comes in. It has been several weeks. I am not comfortable driving my vehicle with this warning light on plus whatever they did since I assume this is a vital safety component/system. Also0, I have no cruise which makes long trips uncomfortable.

The power steering didn't work. There were warning messages displayed for Tire Pressure Monitor Problem, Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Brake System Problem, Brake Hold System Problem, Power Steering System (EPS) Problem, Vehicle Stability Assist (VSA) Problem, Hill Start Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem when turning the car on. This condition was verified by the dealer on both occurrences. First occurrence was 6/8/21. It was towed to Spreen Honda dealer in Corona, CA. According to the the first invoice dated 6/8/21 for the repair there was "Confirmed fault code for C1420 main torque sensor and sub torque sensor, C1421-14 malfunction to steering angle, confirmed multiple fault codes due to rodent damage to the steering system sub harness chewed thru replaced the steering torque sensor sub harness and calibrated the steering angle sensor, cleared fault code now OK." Same problem occurred 7/8/2021. Taken to Spreen Honda again on 7/9/21. Wire harness again replaced, steering angle sensor replaced and power steering calibration performed. I have the wire harness that was replaced. Service advisor stated this is a problem with Honda wire harnesses because the insulation on the wires is soy based. He has seen it many times, including one customer at Riverside dealer who had rodents eat his wire harness four times while he was working there. Not having operational power steering makes driving the vehicle very difficult and potentially dangerous.

Most recently, driving along on a sunny day at about 45 MPH on a flat road. No other vehicles on the road in sight. The collision warning system beeped and flashed the warning on the dash. At the same time the system engaged the brakes momentarily before disengaging. The braking lowered my speed to about 30-35 MPH. The only conclusion I could reach was that the system mistook the shadow of a tree for an object but I have no way to know. This has happened before when taking an exit ramp from a highway when the collision warning flashed and the system engaged the brakes momentarily, dropping my speed somewhat, before disengaging. In both cases, I do not know why the system disengaged, though I am glad it did as other vehicles approached from behind soon after.

On friday, april 2nd, I was driving home on the 710 fwy on the far left lane. I was driving around 75mph and there was an object on the ground which looked like an empty potato chip bag, it wasn't anything that would have done any damage to my car but my honda sense's collision mitigation braking system activated for no reason and alerted me to brake and started applying pressure. I had no reason to stop so I had to swerve into the shoulder lane to prevent my car from braking unexpectedly which could have resulted into a deadly collision if there was a car close behind me. I have footage of the video and requested this to be looked into because if this is a faulty sensory issue, I would like it corrected immediately to prevent further issues. I do not want this to happen again because this incident was very dangerous when I did not have control of my own vehicle and it tried to override my command to keep driving straight.

I own a 6 speed manual sport coupe purchased on 5/30/19. On 2/10/20 I was stopped at a light on a slight downhill 15- 20' behind car in front. Shift was in neutral with my foot on brake pedal. After a while, my car started moving forward. I pushed harder on the brake pedeal but no response and coasted into rear of car. One person in each car and nobody injured. Fearful that brake failure would occur again, had car towed to local honda dealer where purchased. Receipt to me indicted they did diagnostic testing, inspected brake system and test drove car. "advised customer no problems at the moment". As noted before testing, since no manufacturer defects found was charged $139.95. On 2/11, received call from mgr. Of honda svc. Dept. Due to my negative survey responses. Told him I was not satisfied with answer by employee to my question of why forward collision mitigation/fcm did not brake when getting close to car. Mgr. Stated that fcm is designed not to work when car in neutral or reverse. I consider lack of fcm in neutral to be a serious safety design flaw. Mgr. Then recommended that I open case with honda customer relations which done on 2/14. Rep. Took down my info. And asked what I wanted from honda. I said they need to determine why the brake failure happened and what can be done so I have confidence that it will never occur again. She then gave me a case # and stated that it would need to be referred to the "level 1" dept. Handling accidents/injuries/fatalities. Received a call from "level 1" on 2/17 but was told there was nothing they could do/was a local dealer issue and he was to contact the mgr. Of the local honda svc. Dept. I sent voice/e-mails to mgr. Of local honda svc. Dept. On 2/21 noting my experience with cust. Relations/"level 1", and asking what are the next steps -- awaiting response. I am currently driving the car in fear/on edge. *ln

While driving (50+/- MPH) on a two lane state road, my 2019 honda civic hatchback sport cmbs (collision mitigation braking system) automatically engaged, bringing my vehicle very close to a complete stop for no reason I could see. There were no vehicles in front of me in either direction and fortunately no vehicle following or I would have been rear-ended. Clear morning, nothing on the roadway, no wildlife I saw. Dry and sunny, no leaves, no breeze, bare pavement. A sweet june morning in dutchess county, ny. Out of the blue the cmbs engaged automatically applying the brakes so hard I could feel the ABS kicking on and in moments I was at a crawl, then the car simply behaved normally again. I've owned this car less than a week. There is no means provided to shut this feature off permanently. The only way to override the cmbs is to manually turn it off every time I restart the car. It resets every time the car is turned off. This feature may wind up causing more rear end collisions as it avoids front end collisions. What would the consequences be if that scenario happened while on a curve, driving 50 MPH in the rain? Or in rush hour traffic on a highway at 60 MPH (or faster) where commuters typically tailgate across three or four lanes of traffic? This was my very first experience with cmbs in any vehicle and I consider it a total failure and extremely dangerous when it can engage with such force while it's a false alarm.
