Open the full vehicle complaint log (all categories)I was driving today and for no reason at all the cars anti collision system automatically braked hard and could have caused an accident if someone was driving behind me. There was no one, objects or vehicles around my car at the time that would cause it to happen.
When driving, if the sunlight is just right casting shadows in front of the car from trees, or while traveling down a divided highway passing 18 wheelers (mainly in the evening), the shadow created causes a false alarm on the collision avoidance system causing it to react by hard deceleration. This is also accompanied by the audible BRAKE alert coming across the gauge cluster. While at highway speeds, it can really startle you and possibly cause you to be rear ended due to the sudden and Unneed braking. You have to get hard on the accelerator in order to overcome the computer trying to slow you down. There is a recall on OTHER Honda vehicles for this exact thing, and it needs to be expanded to the Civic as it suffers from the same problem. The approximate date section only contains 1 date, but yet it has happened numerous times.
I was driving through an intersection when my car suddenly applied the brakes even though the vehicle in front was way ahead of me and in motion. Thankfully the driver behind me was not close enough to have collided with the rear of my vehicle. Prior to this happening as i was driving on the highway, the vehicle did mark the brake warning sign even though I was at a safe distance from the vehicle in front. This is the first time i have encountered this problem, howevever i am very scared that this could cause an accident in the future if it were to happen again.
I was driving on a surface street going approximately 5 - 8 mph and was 2-3 car lengths from the vehicle in front of me when my vehicles automatic emergency braking system engaged without warning, causing the car behind me to have to brake abruptly.
I got the car with Honda Sensing to include adaptive cruise control, lane departure warning, and forward collision warning. All these systems stopped working within 36 month and under 36000 miles. Honda dealership wants more than $2500 for a fix that I read on the internet does not seems to solve the problem. Many people report that the problem is either not solved or it recurs within 6 months.
