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.
