What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2014 Audi S7, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
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
The contact owns a 2014 Audi S7. The contact stated while driving approximately 30 MPH, the vehicle inadvertently stopped. Additionally, the vehicle was leaking an excessive amount of oil. There was an EPC warning light illuminated. The vehicle was towed to the local dealer however, the mechanic was unable to determine the cause of the failure. The contact related the failure to NHTSA Campaign Number: 22V178000 (Engine and Engine Cooling). The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 118,000.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
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.
System malfunction acc and breaking guard

TURBO FAILURE DUE TO OIL SCREEN GETTING CLOGGED UP.
WE LEASED AN AUDI S7 WHICH WE WERE NOT MADE AWARE OF HAVING A FUEL LINE ISSUE AT ANY TIME DURING THE TRANSACTION. THE DEALERSHIP MENTIONED THEY WERE DETAILING THE CAR AND GETTING IT READY FOR US. WHEN WE WENT INTO THE GARAGE TO SEE THE CAR, IT WAS NOT BEING DETAILED, BUT THE BACK SEATS WERE REMOVED AND GAS WAS BEING SIPHONED FROM THE VEHICLE. WE WERE SHOCKED AND ASKED THE SERVICE TECHNICIANS WHAT THE HECK THEY WERE DOING. WE WERE TOLD THAT THEY WERE PERFORMING SERVICE TO MAKE SURE THE VEHICLE RUNS WELL. THIS WAS VERY DECEPTIVE BUT SINCE WE HAD ALREADY SIGNED THE CONTRACT, WE GAVE THEM THE BENEFIT OF THE DOUBT. THE CAR HAS SMELLED LIKE GASOLINE INSIDE THE CABIN SINCE WE LEASED IT. IT HAS MADE MYSELF, WIFE, AND OTHER FAMILY AND FRIENDS NAUSEOUS ON NUMEROUS OCCASIONS. I REPORTED THIS TO THE KEYES AUDI DEALERSHIP SEVERAL TIMES AND ALL THEY COULD TELL ME WAS TO WAIT FOR THE SMELL TO GO AWAY. THIS IS NOT ACCEPTABLE, BUT SINCE I HAD BEEN TRAVELING AND NOT USING THE CAR MUCH IT WASN'T A MAJOR PRIORITY UNTIL RECENTLY. A COUPLE OF WEEKS AGO, I NOTIFIED AUDI CORPORATE REGARDING MY SERIOUS CONCERN AND THEY TOLD ME TO TAKE THE CAR INTO THE DEALERSHIP FOR SERVICE. WE DID THIS, AND THE SERVICE CONSULTANT TOLD MY WIFE AND I THEY HAD REPLACED THE FUEL LINE PRIOR TO OUR LEASING OF THE VEHICLE BUT THAT THEY "MAY HAVE" REPLACED A FUEL PUMP THE DAY WE PICKED THE VEHICLE UP AND THAT GASOLINE MIGHT BE ON THE SEATS SINCE THAT'S WHERE THE PUMP IS LOCATED. I PROCEEDED TO ASK HIM HOW IT'S POSSIBLE THAT A FUEL PUMP ON A BRAND NEW CAR GOES BAD ALL OF A SUDDEN AND SPILLS GAS ON MY SEATS AND HE TOLD ME IT HAPPENS ALL OF THE TIME. LUDICROUS. MY WIFE AND I ARE EXTREMELY UNCOMFORTABLE AND FEEL VERY UNSAFE IN A HIGH END VEHICLE THAT SHOULD NOT HAVE ANY ISSUES WITH FUEL LINES/PUMPS OR ANYTHING RELATED. MY WIFE AND I ARE APPALLED AND ARE WILLING TO TAKE LEGAL ACTION. WHATEVER IT TAKES TO FEEL SAFE AGAIN. *TR

Powertrain (other)

From owner reports, verbatim
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.
TURBO WHEEL SHEARED OFF THE SHAFT AND STALLED THE CAR WHILE DRIVING AT < 5MPH IN PARKING LOT. UNABLE TO THEN START CAR AND MOVE IT - NEEDED TO BE PUSHED TO ONE SIDE TO AWAIT THE TOW TRUCK. THERE WERE NO SYMPTOMS OR WARNINGS OR CEL PRIOR TO THE FAILURE. OTHERS HAVE REPORTED SAME FAILURE AT HIGHER SPEEDS OR EVEN ON HIGHWAYS. THIS FAILURE MODE IS DANGEROUS AND COULD RESULT IN LOSS OF VEHICLE CONTROL. AUDI SHOULD BE PERFORMING A RECALL ON THIS FOR ALL THE VEHICLES THEY INSTALL THIS ENGINE MODEL INTO. I WAS ONLY RECENTLY MADE AWARE OF THE ABILITY TO REPORT THIS ISSUE HERE, HENCE THE DELAY IN MY DOING SO.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
