   THE AUTOMATIC START/STOP FUEL-SAVING ENGINE FEATURE ENGAGES PREMATURELY, BEFORE THE VEHICLE HAS COME TO A COMPLETE STOP. AS A RESULT, THE VEHICLE FEELS LIKE THE BRAKES HAVE BEEN ARTIFICIALLY AND AGGRESSIVELY APPLIED TO BRING THE CAR TO A COMPLETE STOP BEFORE THE START/STOP ENGINE FEATURE OTHERWISE SHOULD HAVE ENGAGED. AS A RESULT, FOR VEHICLES FOLLOWING CLOSE BEHIND, THE EFFECT WILL BE THAT THE AUDI VEHICLE IN FRONT OF THEM WILL APPEAR TO LURCH TO A STOP, THUS CREATING A RISK OF A REAR-END COLLISION. THIS ISSUE HAPPENS EACH AND EVERY TIME THE START/STOP FEATURE IS ACTIVE, AND TYPICALLY INVOLVES ARTIFICIAL AND PREMATURE BRAKING/STOPPING AT LOW SPEEDS AS THE VEHICLE IS APPROACHING WHAT WOULD OTHERWISE BE ITS NATURAL STOPPING POINT BASED ON THE DRIVER-APPLIED PRESSURE TO THE BRAKE PEDAL.
