“The automatic braking system was activated when I was driving ~40mph on a straight highway under clear weather conditions with no cars in front of me. Fortunately, the car behind me was able to avoid me but I did receive a few honks and a couple of finger salutes. I immediately reported the problem to my dealership and still haven't heard from them - 4 hours and counting.”
NHTSA complaint #11407256, filed 2021-04, 7,200 miles“The warning lights come on for the breaking system road departure mitigation system problem see your dealer, collision mitigation braking system problem see your dealer adaptive cruise control system problem see your dealer. With the acc and brake system warning lights on and the car only has 2516 miles on it. This does not make me feel safe at all to drive. What is being done to fix this problem as there are multiple reports of this kind? Is there a fix now!!”
NHTSA complaint #11391159, filed 2021-02, 2,516 miles“I was driving on route 42 at 11:52 PM and my brake light illuminated on my dashboard indicating me to hit the brake so I stepped on the break so my car wouldn't brake itself. There was nothing directly in front of me for that like to come on but it did. The highway was dry there was a little bit of cars on the highway but in front of me”
NHTSA complaint #11759697, filed 2026-08“I’m taking my car to the body shop over five occasions and have to take it back one due for it being a computer chip, which was replaced, but the lights on my dash all of them comes on after the second start up. Cruise control doesn’t work brake code doesn’t work all the lights for staring brakes says to check everything.”
NHTSA complaint #11758978, filed 2026-08“There has been no incident with my vehicle but I am writing to look into this issue. I see several threads online regarding these warning lights that just randomly pop up without any indicator of a problem with the vehicle. This stops all these assistive features from responding if there were a hazard. Please look into this because Honda is not responsive to the recall issue.”
