2023 HONDA CIVIC Forward Collision Avoidance Problems

I am reporting repeated electronic safety system malfunctions in my 2023 Honda Civic Sport sedan that occurred while driving at highway speeds and present a serious safety concern. In June 2025, while driving at highway speed, multiple warning lights and messages suddenly appeared, including: Brake System Warning, Road Departure Mitigation System Warning, Parking Brake/Brake Hold Warning, and Adaptive Cruise Control Warning. These warnings appeared simultaneously without prior notice, raising concern about whether the braking and safety systems were functioning properly while the vehicle was in motion. I took the vehicle to a Honda dealership for diagnosis. The dealer did not identify a specific electronic or mechanical defect and instead claimed the issue was caused by liquid spilled near the electronic parking brake switch. I was told the repair was not covered under warranty and paid approximately $600 out of pocket. No evidence was provided explaining how this would cause failures across multiple safety systems. In January 2026, the same group of warning lights appeared again under similar conditions while driving at highway speed. This recurrence strongly suggests the issue was not caused by driver error but may be related to an intermittent electronic, sensor, or control system defect. I have a scheduled dealer appointment tomorrow to address this second occurrence of electronic malfunctioning. Because these warnings involve critical braking and collision mitigation systems and occurred while the vehicle was in motion, they present a potential safety risk. I am submitting this complaint so NHTSA can document and evaluate whether this represents a broader safety defect.

I bought my car from Honda Civic on colerain avenue Cincinnati Ohio in 2023. In December 2024 I started having issue with my driver assistant technologies. My driver assistant technologies lights started flashing . As they were flashing none of my assistant technologies were working. When they finally went off it gave me a message to call the dealer. Which I did immediately. They told me to bring my vehicle in and they would check it. Service department calibrated the camera on the windshield. Picked my vehicle up about a month and a half after it happened again. Brought my vehicle in for the second time to the service department. Picked my [XXX] up for the second time. About a month and a half to two months and happen again. Vehicle in for the third time. They stated that it was a windshield that I had replaced by someone outside of Honda. They said I had to have my windshield replaced and also the camera by them. It cost me $1,000 for the windshield the camera was not charged to me. At this point it was like a guessing game. Picking my vehicle up for the third time. 2 months after picking it up the third time it did it again on [XXX]. I am looking for another Honda dealer to take it to to see if they could figure out what it's going on with that. I have all of my receipts. They can't seem to fix it at Honda Civic on colerain. I was told that if they couldn't fix that I would have to keep my vehicle as is. This is a safety hazard all I'm asking for is to have my vehicle and working condition. That is not happening.

I get a random warning that is an issue with the braking system and the Brake light comes on. The lane departure and cruise control is shut off while the vehicle is in motion. There is a sudden and unexpected drop in speed when the cruise control is shut off by the vehicle. The vehicle remains operable without the systems activated the warnings go away after restarting.

I rear ended a vehicle and my brakes did not respond nor the emergency system activate I gave a dash cam on the incident and no one has inspected the car for that failure

I was driving at highway speeds, randomly all brake system warning lights come on. All ADAS systems are inop, EPB is inop, my brake pedal would get soft intermittently while braking. Multiple DTC’s were stored every visit. I was almost in multiple accidents because of this issue. It took over 6 visit to local Hondas dealer to get this issue fixed. All they would say “oh the codes don’t mean there is a problem” Honda is not warranting their cars. I contacted corporate and they did not care.

I was getting on the interstate when all of a sudden the collision mitigation assist and lane keeping assist pop up on my dashboard. It was a very scary moment.

Under multiple conditions, both intercity highways and two-lane country highways the cars adaptive cruise control with randomly slowdown/brakes extremely hard. In one specific instance I was driving home in the middle of the night with a vehicle behind me and with no other oncoming traffic or cars in passing lanes and the adaptive cruise "brake checked" the car behind me, I was able to react and cancel the adaptive cruise and avoid an accident. When adaptive cruise is set it will also aggressively approach the car in front, instead of gradually slowing down it will continue at the set speed until the car realizes it's to close and will slam on the brakes to slow down. When adaptive cruise is turned off the car will slam on the brakes if you attempt to accelerate to pass someone and coast back to set speed. in other words, the car will slam on the brakes to resume the set cruise speed. Fortunately, no cars have been behind me when this has happened. Nowhere does it say that this will happen when using normal cruise control? Speeds and conditions varied from city traffic going 20 - 40 mph, the highway going 55-65 and the interstate going 70-80 mph. some instances were at night others were during the day.

The brakes slam on there own causing all safety features to go out and the car to go out of control. This is the 3rd time this has happened in 3 months. The dealership is telling me they won’t look at it for 3 months I could be killed in that time my car is dangerous

My vehicle was giving me the “you’re going to collide with something warning which is a loud alarm. I wasn’t even close to anything. I called and they said they had people stopping by all day with the same complaint. Then he told me that it can even do it when there is a hard rain.

I was driving on the freeway my car alerted me to hit the break as there was someone in front of me breaked. I hit my break and my airbags went off. There was no damage to the car in front of me at all that it felt unnecessary for an air bag to go off. my windshield cracked and airbags under my feet and front went off.
