Example complaints

Brakes: “At highway speeds the collision mitigation system will go off for no reason causing a sudden hard braking. This seems to be extremely dangerous if vehicle is traveling on wet or icy roads, in close quarter construction zones or if vehicle happens to be in a turn. Unfortunately if another vehicle was following too close would be an accident, which I have heard has happened. I have taken truck to Kenworth service twice and they said there is nothing they can do. It is a required system and are just very sensitive. I see nothing good about this system. …”
