NHTSA Complaint #10872929 — 2012 AUDI Q7

PULLING OUT MAKING A LEFT TURN FROM A STOP, VEHICLE SUDDENLY HESITATED, POWER TO ENGINE WAS INTERMITTENT AND JERKY, AND ACCELERATION WAS POOR TO NONE. MANY WARNING LIGHTS CAME ON (STABILITY, TIRE PRESSURE, ANTI-LOCK, ETC.). STEERING WHEEL WAS ALSO SHAKING SLIGHTLY (POWER STEERING MOTOR?). CONDITION CONTINUED FOR ABOUT A MILE WHILE VEHICLE PROCEEDED TO HOME. TURNING VEHICLE OFF AND ON RESOLVED THE PROBLEM. ON INITIAL CALL TO DEALERSHIP I WAS TOLD "THEY DO THAT SOMETIMES; YOU NEED TO TURN OFF/ON TO REBOOT SYSTEM". AFTER TAKING FOR SERVICE FOUR DAYS LATER NO ISSUES WERE FOUND OTHER THAN SOME "MISFIRING" CODES ON DATE OF EVENT. I WAS TOLD THIS WAS NOT A SITUATION THEY'VE SEEN AND NO SERVICE BULLETINS EXISTED ON THE BEHAVIOR. AS THE INITIAL PROBLEM CONTINUED UNTIL CAR WAS TURNED OFF/ON IT SEEMS LIKELY THAT THE INITIAL INFORMATION FROM THE DEALERSHIP WAS CORRECT AND THIS IS A COMPUTER CONTROL PROBLEM. WE HAVE OWNED THE CAR SINCE NEW AND NOT EXPERIENCED THIS ISSUE BEFORE. THE CAR CURRENTLY HAS ABOUT 60K MILES ON IT. FORTUNATELY THERE WERE NO INJURIES BUT A LOSS OF POWER PULLING INTO TRAFFIC IS A VERY SERIOUS FAILURE. IF THIS IS SOMETHING THAT "HAPPENS SOMETIMES AND YOU NEED TO TURN THE VEHICLE OFF/ON TO REBOOT THE COMPUTER", IT NEEDS ATTENTION AND NEEDS TO BE RECTIFIED AS A SINGLE OCCURRENCE IS ONE TOO MANY.
