Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Engine
7 reports
“The ECU control module Is a known problem with this car by a great amount of owners. It is such a problem that the car part is on back order for weeks at a time. The biggest issue about this is that the car just randomly doesn’t turn on and randomly shuts down on the roads, freeways and even U turns. It can potentially lead to critical injuries”
Forward collision avoidance
3 reports
“The adaptive cruise control and Brake asist features are only working occasionally. Some times it switches on and off DURING traffic while the car is moving. This is a severe saftey issue IMO and needs to be taken care of by Audi.”
Lane departure
2 reports
“Acc audi breaking guard fault lane assistance malfunction.”
Fuel/propulsion system
2 reports
“TURBO FAILURE DUE TO OIL SCREEN GETTING CLOGGED UP.”
Power train
2 reports
“DRIVING ON THE HIGHWAY DURING A ROAD TRIP FROM FLORIDA TO WISCONSIN, OUR ENGINE STALLED WHILE COMING TO A STOP. WE MANAGED TO GET IT TO AN AUDI DEALER AND IT WAS DETERMINED BOTH TURBOCHARGERS WERE BROKEN. BOTH SHAFTS HAD SNAPPED AND THE CAR WAS UN-DRIVABLE LEAVING US STRANDED IN GEORGIA. THIS IS A DESIGN ISSUE FOR THE 4.0T ENGINES AND VW/AUDI HAS REFUSED TO IMPLEMENT A FIX BESIDE THE OIL SCREEN BAND-AID. THE OIL SCREEN, SINCE IT IS NOT SERVICEABLE, WILL SLOWLY ACCUMULATE DEBRIS AND RESTRICT OIL FLOW TO THE TURBOS AND CAUSE THEM TO BE STARVED OF OIL. SIMPLY REMOVING THIS OIL SCREEN WOULD BE A SUITABLE FIX BUT AUDI HAS REFUSED TO ACKNOWLEDGE THEIR DESIGN IS FAULTY. THIS FAILURE COULD BE EXTREMELY DANGEROUS IF THEY WERE TO CAUSE THE VEHICLE TO STALL AT SPEED OR WORSE, HAVE THE ENGINE IGNITE DO TO THE MENTAL ON METAL GRINDING OF THE TURBO TURBINE. PLEASE HELP US.”
