2020 Honda CR-V: adaptive cruise control problems

Filed May 3, 2026 · Driver assistance, Electrical · AL

In November 2025 a new transmission was installed Curry Honda in Atlanta GA on my 2020 Honda CR-V. The new transmission came with a 3 year/36,000 mile warranty. In March 2026 my vehicle broke down and was towed to Tameron Honda in Daphne Al where a speed sensor was replaced at my expense of 388.44. The adaptive cruise control was not working prior to this repair. Within two weeks the vehicle experienced further issues and had to be driven in a compromised condition back to Curry Honda in Atlanta where the transmission wire harness was diagnosed as corroded and replaced at a cost of 1696.99. My vehicle has been garage-kept its entire life except when in the care of a dealership. Corrosion on a recently replaced transmission in a garage-kept vehicle cannot be attributed to environmental exposure or owner neglect. It points directly to a defective part of improper installation at Curry Honda. These failures occurred within months of a new transmission installation with no prior history of issues. I believe this is a safety defect as the vehicle broke down unexpectedly and had to be driven in a compromised condition posing a safety risk.

Every dashboard light came on. Engine, brake and all the adaptive controls were flashing. The whole dash was lit up and my cruise control and lane assist wouldn’t work. Among other things I’m sure. I want to know if this is going to happen again and what about the head gasket now? Can you do the update/ thermostat on my vehicle since obviously it is defective? The car only has 65,000 miles on it. I always heard Hondas were the best vehicles. This is now very concerning. Please advise.

When I am in adaptive cruise control mode, and I am in the left lane and a large vehicle like a semi-truck or a pickup truck pulling a large trailer is in the right lane passes me, from time to time it will engage the braking system even though there is nothing in front of my vehicle. Recently it has also been happening if I am in the right lane and vehicle exits the highway on an off ramp. I have been lucky to date that no vehicle was behind me when the braking system engaged, or there would have been an accident. This issue has been occurring ever since I bought the 2020 CRV new and have brought it to the attention of the dealer several times, and they say they could not find an issue. My last scheduled maintenance appointment they recommended recalibrating the system, and the issue is still there.

Several months ago, I was driving on the interstate with cruise control on. I passed a disabled vehicle parked on the shoulder of the highway. My car started to brake like crazy on its own when I passed this vehicle. Fortunately there were no other vehicles next to me or behind me or I could have had a very serious wreck. Last weekend, I was driving in town and already slowing down on my own for a vehicle in front of me. I was barely touching the brakes but the automatic braking slammed on the brakes for no apparent reason and almost caused the car behind me to rear end my vehicle.

Driving on I-275 freeway along with my friend to Airport. Both Lane Keep Assistant and Adaptive Cruise Control were ON. I kept cruising at 65 miles/hour and drove about 7 miles with no issues. My vehicle slowed down by detecting a vehicle ahead of me driving in 55 m/h. As the next line was free, I moved to the left line and my vehicle started accelerating to 65 m/h. It had not detected a stopped vehicle ahead of me. I expected the ACC OR CMBS features to detect and slow down my car but no alert was received. Also Automatic Emergency Breaking system not slowed down or stopped my vehicle. I applied hard breaks but the vehicle hit the stopped vehicle and both airbags deployed. Lucky that we are safe and no injuries to us but car was totaled. Progressive Auto Policy: [XXX], Police Incident Number: [XXX], Ticket Number: [XXX], Honda complaint number [XXX].

In March/April 2020 I was driving at 65 miles per hour on a rural highway. The only vehicles on the road were my car, the pickup in front of me and the pickup behind me. Since the highway was so quiet, I decided to try Adaptive Cruise Control (ACC). I set it for 65 miles per hour (the speed limit). We had been driving for about 15 minutes, each car maintaining the same speed and distance. The pickup in front of me turned on his turn signal for a right turn and entered the right turn lane. As my car approached the pickup, in the turn lane, the automatic braking system activated. I lunged forward, the seat belt activated, braking warning was displayed on screen and there was an audible alarm. I managed to take control of the vehicle and to accelerate. I was afraid the vehicle behind me would collide with me. I turned off ACC and tried to regain my composure. When the pickup moved into the right hand lane, there was nothing in front of me as far as the eye could see; just open highway. I will never use ACC again. Yesterday, December 19, I was driving on a side street. I had just exited a school zone, speed limit 15, and my speed was now approximately 22, no vehicles in front of me just some cars parked at the curb ahead to my right. There was an audible tone and the word BRAKE displayed on the screen. The brakes did not activate.
