Consumer Description
When on cruise control, the vehicle frequently brakes hard at highway speeds, jerking our bodies and forcing cars behind us to brake hard as well. Sometimes this happens when we’re beside a semi truck or a car changes lanes far in front of us, but often there’s nothing. There is no warning prior to the braking.
