AUDI Q5 DURING AFTERNOON HR'S DRIVING FROM WORK 30 MILES AND OUTSIDE TEMPERATURE 95F, INSIDE MAINTAINING TEMPERATURE AROUND 65F COOL RUNNING, AT LEFT TURN SIGNAL ABOUT TO TURN LEFT ENGINE STOOPED AND STEERING WHEEL LOCKED . IT'S STRUCK IN ROAD ABOUT 45 MIN AND WHEN TRIED TO START IT'S UNABLE TO START. LATER AFTER 45 MINUTES WHEN TRIED IT STARTED AND ABLE TO PULL TO PARKING LOT. ONCE I STOPPED AND START AT PARKING LOT SAME ISSUE ENGINE STOOPED ITSELF , WAITED FOR 30 MINUTES THAN TRY TO START IT STARTED - I DROVE IN PARKING LOT FOR FEW YARDS AGAIN ENGINE STOOPED AND STEERING WHILE LOCKED. I TOWED TO AUDI SHOWROOM. SHOWROOM SERVICE SAYING IT'S WORKING FINE NO ISSUES. THE ONLY MY CONCERN IS THAT IF IT'S HAPPEN IN FREEWAY @ SPEED 60 MPH ENGINE STOPS THAN THINK ABOUT THE CONDITION OF ACCIDENT. LIGHT INDICATOR ON THE VEHICLE IS...

THIS HAS HAPPENED NOW SEVERAL TIMES, WHEN THE CAR COMES TO A COMPLETE STOP OR JUST ABOUT A COMPLETE STOP, THEN TRYING TO ACCELERATE THERE IS NO THROTTLE RESPONSE INSTEAD OF ACCELERATING AS EXPECTED. IS THE ABS SYSTEM CUTTING POWER TO THE ENGINE? THE CAR IS 'DEAD' FOR ABOUT TWO SECONDS AND THEN POWER IS RESTORED. I WAS ALMOST HIT BY ONCOMING TRAFFIC. REPORTEDLY, THIS IS APPARENTLY WIDELY DOCUMENTED AND ONGOING SINCE AT LEAST THE YEAR 2000, AND NOT SPECIFIC TO AUDI...WHAT IS THE NHTSA DOING ABOUT THIS??? *TR
