2013 Mercedes-Benz E350 Forward collision avoidance Problems

“Pre-safe inoperative warning message comes on at random times. I’ve taken the vehicle in to address this issue, but Mercedes claims they did not see the message, and there are no error codes. I purchased this vehicle because it comes with this safety feature - I find it unacceptable that it does not function.”

“While using the adaptive cruise system (Distronic plus) on an open section of interstate highway the system will act as though it detects cars where there are none. Sometimes this will result in a slight slowing down of the car without the braking warning signal, but sometimes the braking warning signal will come on and is followed by aggressive braking for no apparent reason. This has happened several times where the system falsely detects the need to decelerate on its own when there is nothing in the road to cause it.”
