MY 2006 AUDI A6 LOST ALL ENGINE POWER WHILE DRIVING AND THE STEERING WHEEL LOCKED UP. THIS HAPPENED ON THREE SEPARATE OCCASIONS. THE MANUFACTURER HAS REFUSED TO TAKE THE CAR BACK, DESPITE THE LIFE THREATENING SAFETY CONCERNS ASSOCIATED WITH THIS PROBLEM. I HAVE NOTICED OTHER POSTED COMPLAINTS FOR THE SAME PROBLEM. *TR
I HAVE A 2006 AUDI A6 WITH VIN NUMBER WAUDH74F96NXXXXXX. ON SEPTEMBER 21ST WHEN I WAS DRIVING THE VEHICLE IN MY OFFICE PARKING LOT, THE TRANSMISSION DROPPED DEAD WHEN VEHICLE WAS IN MOTION AND I WAS UNABLE TO MOVE THE CAR. I STOPPED THE IGNITION AND RESTARTED THE CAR AND IT CAME BACK. I HAD THE SAME ISSUE ON SEPTEMBER 26TH, AFTER PULLING OFF MY DRIVEWAY AND AFTER I WAS EXITING MY HOME THE CAR DIED AGAIN LUCKILY I WAS ON LOCAL ROAD AND THIS TIME AFTER STARTING THE CAR, I STARTED GETTING CHECK ENGINE LIGHT. I CONTACTED AUDI DEALER AND WAS ABLE TO GET APPOINTMENT ON OCTOBER 3RD. THE DEALER INFORMED ME THAT MY CAR HAD ENGINE OIL SLUDGE ISSUE AND THEY HAD TO CLEAN THE ENGINE AND IT WOULD TAKE AT LEAST A WEEK BEFORE THEY COULD GIVE ME THE CAR BACK. AFTER A WEEK DEALER INFORMED ME THAT THE VEHICLE WAS SERVICED BUT WOULD NOT GO ABOVE 20 MILES AND HOUR, DEALER HAD NEVER SEEN THE PROBLEM BEFORE AND WAS AWAITING A FIX FROM AUDI ENGINEERING. TODAY IS 16TH AND MY CAR IS AT THE DEALER FOR ALMOST 2 WEEKS NOW AND I STILL DO NOT HAVE THE VEHICLE. I CONTACTED AUDI AND OPENED A CASE, CASE NUMBER 60373673, SO FAR AUDI IS OF NO HELP. DEALER IS DOING EXCELLENT JOB OF COMMUNICATING WITH ME BUT AUDI NEEDS TO LOOK AT THE ISSUE AS IF THIS PROBLEM OCCURS ON NATIONS HIGHWAY, PEOPLE MAY GET INTO SERIOUS ACCIDENTS. *NM
