NHTSA Complaint #10551165 — 2010 BMW 550I

FROM A VERY SLOW ROLL THERE IS A DELAY IN ENGINE RESPONSE OF 1-2 SECONDS. THERE IS ALSO A DELAY IN ENGINE RESPONSE IN THE 10-30 MPH RANGE OF THE SAME LENGTH OF TIME. THE SLOW ROLL EVENT CAN CAUSE CONFUSION TO OTHER DRIVERS WHO BELIEVE YOU ARE YIELDING THE RIGHT AWAY WHEN YOU DO NOT ACCELERATE IN A TIMELY MANNER GOING FORWARD OR MAKING A TURNING MOVEMENT. THERE IS THE POSSIBILITY OF AN ACCIDENT IF A PEDESTRIAN, BICYCLIST OR ANOTHER CAR TAKES THE DELAY AS A SIGN THAT THEY HAVE THE RIGHT OF WAY. THE DELAYED ENGINE RESPONSE IN THE 10-30 MPH RANGE IS OF GREAT CONCERN WHEN ATTEMPTING TO MERGE ONTO A FREEWAY FROM A SHORT ON-RAMP IN MODERATE TRAFFIC. THE ENGINE RESPONSE DELAY IS VERY PRONOUNCED UNDER HARD THROTTLE AND HAS CAUSED HEAVY BRAKING BY CARS UNSURE IF I'M GOING TO BE AT SPEED WHEN MERGING. *TR
