ON APRIL 15 2020, WAS ENTERING A PARKING SPACE IN FRONT OF A SPROUTS SUPERMARKET AT 12500 WESTHEIMER RD., HOUSTON, TEXAS 77077.

THIS IS AN EXPENSIVE CAR AND CAME EQUIPPED WITH THE EMERGENCY CRASH SYSTEM. THIS FEATURE DID NOT WORK TO STOP THE CAR FROM HITTING THE BUILDING. IN THE PAST IT HAS STOPPED THE CAR BUT ONLY MOST OFTEN IT DOES NOT WORK...NO ONE WAS INJURED NOR WERE ANY PEOPLE ON THE PARKING AREA AFFECTED. *TR

HESITATION UPON ACCELERATION. THE ENGINE DOES NOT RESPOND IN A LINEAR MANNER WHEN PRESSING THE GAS PEDAL.
