Owner complaint summary

While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the SBS system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.
