2022 Honda Civic: false forward collision warnings

Filed Jul 27, 2025 · Brakes, Driver assistance · MI

On July 1 and July 27 when I started the vehicle a warning came on saying collision mitigation braking issue. See your dealer. It is available for inspection upon request. Will call dealer tomorrow. Not inspected yet. Will call dealership tomorrow. By info we are reading, there is no solution to this. Huge concern. Huge safety issue.

Went to start my car one night after it had been perfectly fine throughout the day when 5 warning lights came on, Lane Keeping assist system, Collision mitigation braking system, Road Departure mitigation system. Auto High Beam problem and Adaptive Cruise Control system problem. I immediately went online to see how i could possibly fix the problem and found numerous message boards with people with fairly new low mileage Hondas complaining about the same issue and stating either various completely different solutions or no luck finding a solution. Other than those warning lights everything else on the car is functioning right and the battery is still in good shape.

while in park, out of the blue, four different types of ADAS lights came on the dashboard all at the same time. (ACC, Collision mitigation system problem, road departure mitigation system problem, & brake system). Cruise control, automatic, high beams, etc. no longer worked. Dashboard said to take the car to the dealership. at the dealership, Honda said there was a malfunction with the radar sensor. They ran the diagnostic test, and after updating the system, the problem was fixed.

-What component or system failed or malfunctioned, and is it available for inspection upon request? Forward collision warning and accelerator pedal How was your safety or the safety of others put at risk? Traffic travelling at 45+ mph had to change lanes to avoid rear ending me after I pulled out onto the frontage roads from a stop and the accelerator pedal stopped responding (rpms went to idle). If there was less time to pull onto the road and/or others couldn't change lanes this could have been very bad. -Has the problem been reproduced or confirmed by a dealer or independent service center? No. -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. -Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The screen was flashing "BRAKE" while I had the gas pedal pressed to the floor (after realizing the car wasn't responding) with no response from the car for probably 3 seconds while traveling less than 10 mph. I had no way of knowing the accelerator pedal would become unresponsive after pulling out into traffic. -My theory is that a pedestrian on the right sidewalk potentially made the (camera?) system think I was going to hit them but the person was not in or even that close to the road and my car wasnt pointed at them at any point. -This happened awhile ago (unsure of exact date) but couldn't help but think of how bad it could have been there was less of a gap or other drivers were unable to change lanes and it still makes me uneasy pulling out into fast paced traffic unknowing if the car will have this happen again potentially causing a serious accident.

This vehicle is two years old, has 70,000 miles on it now. It’s worth noting that this issue started when it had 15,000 mile on it several years ago. I took it to the dealer, but they told me they wouldn’t do anything about it since the light no longer indicated an issue. Randomly, the vehicle will suddenly say “collision mitigation system problem, see dealer” and “adaptive cruise control problem see dealer”. These two warnings always show up together, and always turn off lane keep assist and all cruise control options until the warning disappears. The warnings will pop up 5-6 times a year and sometimes last several days, sometimes only seconds. Dealer initially told me it may be due to water after it rains but now it’s happening even during dry weeks when we haven’t had rain in ages.

I owned 2 of these 2022 civics equipped with Honda's Collision mitigation braking technology. This is the year they removed the forward radar and relied only on a single camera unit. I was involved in a rear end collision where I was the rear ender even with the distance setting on the furthest setting. The accident was on the highway at about 40MPH. A vehicle Merging on to the highway stopped in front of me in my lane. I was using adaptive cruise control. I can tell you the responsive of this system had me worried from in several other situations I was in. Not only did the adaptive cruise fail detect and slow the vehicle based on the vehicle in front of me, the safety system did not make any attempt to slow the vehicle and no detection was made by the system until about .2 seconds (or about 6') prior to the actual impact. I investigated the safety systems logs with a Honda mechanic by connecting a device to the OBD2 port and downloading the logs to a computer to verify indeed it failed to properly detect any obstacle until it was far to late. This seems to be a concern other Honda drivers have expressed as well with this revision of their Collision mitigation braking system. I believe they market as if this and the adaptive cruise system are features you can rely on to keep you safe and while I understand it can not account for every situation this was a perfectly clear day in Arizona at about 5:30pm in moderate day light. I believe this system is dangerous and has serious flaws that do not properly detect vehicles in front of you in many situations is extremely slow to react in almost every situation. I attempted to upload these logs but you do not accept the file format they were exported in. If I can send these another way please let me know.

The Collision Mitigation System has spontaneously engaged 4 times with no obstacles in front or to the side of my car. 3 incidents were on city streets with a low rate of speed. The 4th incident happened on the freeway at about 65MPH! I had no vehicles in front of me or to the side of me but I had several behind me. The car came to a screeching halt on the freeway with a truck behind me. Thankfully the truck was far enough behind that he was able to maneuver around me. I was able to get the car going and pulled over to the shoulder of the freeway and threw up because I thought for a moment that I might die if the truck had slammed into me. It was very close and the truck driver was pretty angry as he passed. There were no obstacles in any of the 4 instances. I asked about the issue during the next routine tune up but was told they couldn't replicate it and no codes from the car. It's happened 4 times since June 2021 when I bought the car brand new from the Honda dealership. I'm scared to get on the freeway now after that last incident. They can't replicate it they said - so now what do I do with a car I can't rely upon to be safe?

Recently I saw the Collision mitigation Breaking system problem and Adaptive cruise control system problem in my car. Honda has not resolved this issue, so taking it to the dealer will not resolve the issue and it is a safety issue because without any reason at any speed the car can abruptly stop and cause accidents. I asked the Honda dealer if they can disable this function and they said they can’t disable it. That is why I don’t feel safe driving this car.

Adaptive Cruise Control (ACC) has been randomly shutting off out of nowhere during my drive. This has been happening off and on for two months and is NOT happening due to the reasons it could happen in the owners manual. It will not turn back on unless I pull over and shut off the car or place the transmission into park which forces me to leave a highway. Today without ACC even on I get 5 warnings including collision mitigation brake system failure and to see a dealer (pictures attached for all 5 warnings that came on the dashboard today). I saw Rudolph Honda in El Paso TX today and the service center lady told me she is aware of this problem and already tried to diagnose another 2022 Civic with no luck and there are no rentals to help me leave my car for further diagnostics and i cannot be seen for a week at Borman Honda in Las Cruces NM nearby where I live. So Honda is putting me out for my time and money i give them for this faulty ACC and related safety systems. I feel unsafe as this shuts off out of no where and could cause me to get rear-ended as last time this happened the car suddenly decelerated with someone behind me. This car is available for inspection.
