There is a warning flash to brake when there is no vehicle or anything in front or alongside. This has happened several times. I am concerned if vehicle is safe to drive.
The contact owns a 2021 Honda Civic. The contact stated while driving on several occasions at approximately 70 MPH, and changing lanes, the Forward Collision Avoidance Automatic Emergency Braking system inadvertently activated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 24,000.
The vehicle has on numerous occasions performed automatic braking when no cars are near the front. This is causing the car to break abruptly and I’m fearful that a vehicle to the rear of me will collide due to the erratic and forceful application of the breaks.
Driving down the road sunny, dry roads, no vehicles around, car starts flashing brake and slams on break has happened 3 or 4 times. Also, Diver assist warning lights keep coming on with radar obstructed. Honda please do something about this before someone gets hurt. I am a single mother and loved this car until recently. I don't have the money to pay the dealership to run diagnostics and lie and say they don't know what's wrong because they cant make it happen again.
Automatic Emergency Braking (AEB) system alerted and engaged emergency braking on a clear road when there was no obstacle in the vehicle path.
Car will display BRAKE on the dashboard, and automatically brake without an object in front of vehicle, causing vehicles to have to slam on their brakes to avoid collision. Has happen multiple times. Dealership was unable to replicate the problem as it is very unpredictable and does not have any consistency as to when it happens.
Forward collision warning and braking has falsely activated with no vehicles ahead of car. First, "BRAKE" warning flashed for no reason while driving on a three lane road on Virginia Rt 286 and Rt 50 interchange. Second, driving in right lane, vehicle ahead was taking exit and was clear of my path, car flashed BRAKE warning, then started braking. Third, while using Adaptive Cruise Control (ACC) on highway, a passing car changed lanes into my lane. Due to distance, a car length, and smaller speed difference, emergency brakes activated. However, if a passing car operating at a faster speed (>5 mph est.) the car won't brake. The third problem is annoying as it creates an unsafe situation for people following too close (which they should not). Additionally, my brain is processing the situation faster than the HONDA SENSE can, Honda needs to expand their recall from Accord, CR-V, and Pilot to ALL vehicles with HONDA SENSE.
Car will randomly hit the brakes when adaptive cruise control is on. It will hit the brakes even though it doesn’t detect anyone in front, it will slow down a good 10-15mph before speeding back up.
I experienced a false positive forward collision alert warning and subsequent, brief automatic emergency braking during two (2) episodes. Fortunately, my safety nor any surrounding motorists' safety was not at risk. The problem was not reproduced or confirmed by the dealer though my car ADAS was inspected by them. Of the five episodes, I only recorded the last three episodes which did not include an automatic emergency braking component. The episodes only feature the collision warning alert. They are as follow: 02/21/2022, 1930; 02/22/2022, 0805; and 04/01/2022, 0810.
Automatic Emergency braking has gone off twice in 1 month on it's own. No car in front of me and the brakes went off and the "BRAKE" light went off on the dashboard. Yes, my safety was put at risk. I am not seeing any recalls for this Honda but I have read that this is an ongoing problem.
Driving home from work. Cruise set at 73mph. I had just passed another car and was about 600 yrd in front of them on the PKWY, when the car just started breaking and ding, I get multiple warnings on the dash as I'm trying to get out of the way of other vehicles. the car drove normal the next 5 miles under my control but the dash is still lit with a Collision Mitigation system problem, Adaptive Cruise Control Problem, Road Departure Mitigations system problem, Drive Carefully systems initializing problem, Brakes system light. I'll note that there was not bad weather, there was no rain or snow. it was 80F. There was no impact, accident, etc.
I was driving at 55 mph on a clear day with no vehicles or other obstacles in front of my car when the collision mitigation braking system (cmbs) activated and stopped the car suddenly.
