“I am writing to formally lodge a complaint regarding the persistent and premature failure of motor and transmission mounts on the 2014 Audi S6, manufactured and sold by [Automaker Company Name]. This issue has resulted in significant inconvenience and financial burden and, more importantly, poses profound safety implications for the passengers and drivers of affected vehicles. Background: I own a 2014 Audi S6 with Vehicle Identification Number (VIN): [XXX]. Since purchasing the vehicle in 2018, I have experienced repeated failures of the motor and transmission mounts at alarmingly low mileage intervals. The motor mounts have been malfunctioning and requiring replacement approximately every 20,000 miles. This recurring issue has not only resulted in significant expenses but also raised serious concerns about the overall safety and reliability of the vehicle. Safety Implications: The failure of motor and transmission mounts has severe safety implications for the passengers and drivers of the affected vehicles. When these crucial components fail prematurely, they can cause sudden and unexpected movements and vibrations in the engine and transmission systems,…”

“I was driving hit a puddle of water, then all the sudden my power steering went out. I took it in to get looked at, and I'm being told it will cost several thousand dollars to fix the power steering. In addition, this vehicle has air in the suspension, but it now makes sounds when it lifts and takes a longer period of time to lift than normal. Something is effected in my suspension, as well. My vehicle only has 67,689 miles on it, and it should not be having power steering problems from driving through a puddle of water. Lastly, after calling in to Audi, they did a search for the warranty, and Audi did add an extended warranty on the power steering of 125,000 miles or 10 years, which ever occurs first. This means they know about the power steering issue, and with my car being just over 10 years old, the power steering is not covered. I also know a friend who has a 2015 S6 Audi with just under 125,000 miles on it. It happened to him, as well. I will let him know he needs to report the issue, because there is a clear power steering or electrical problem. I have no power steering as of now, and to me, this is a safety issue. I believe something electrical got…”

“MY TURBO CHARGERS BLEW DUE TO OIL STARVATION WHILE DRIVING ABOUT 45MPH IN THE CITY WHILE DRIVING STRAIGHT.”
Steering
2 reports
“POWER STEERING SYSTEM COMPLETELY FAILED ON NUMEROUS OCCASIONS. 18 MONTHS AGO, POWER STEERING FAILED AND WHOLE POWER-STEERING SYSTEM WAS REPLACED BY DEALER UNDER WARRANTY. NOW, 1 MONTH AGO, POWER STEERING COMPLETELY FAILED AGAIN, FOR TWO DAYS, AND THEN RESUMED NORMAL OPERATION ONCE I LEFT SNOW COUNTY (I DON'T KNOW IF THE COLD HAD ANYTHING TO DO WITH IT, DESPITE THE FACT THAT THE SYSTEM IS ELECTRIC-ASSISTED, NOT HYDRAULIC). I TOOK VEHICLE TO MY LOCAL DEALER THAT REPLACED POWER STEERING SYSTEM 18 MONTHS AGO, AND NOW THEY CLAIM THERE IS NOTHING WRONG - BUT THEY SUGGESTED I COULD REPLACE THE WHOLE POWER STEERING MODULE AGAIN FOR $5700, SINCE THE CAR IS NO LONGER UNDER WARRANTY. ON BOTH OCCASIONS, POWER STEERING FAILED, THEN RESUMED, AND THEN FAILED IN A REPEATED MANNER EVERY 30 SECONDS OR SO, WHILE ALSO SOMETIMES REMAINING BROKEN FOR MINUTES AT A TIME. BEHAVIOR DID NOT SEEM TO BE RELATED TO VEHICLE MOTION. I CALLED AUDI OF AMERICA, AND THEY SAY THERE IS LITTLE THAT CAN BE DONE, YET THEY CLAIM THEY'LL TALK TO THE DEALER AND GET BACK TO ME. CONVERSATION DID NOT SOUND HOPEFUL, AND WHEN THE PROPOSED SOLUTION FROM THE DEALER WAS TO REPLACE THE EXACT SAME MODULE THAT WAS…”

“TURBO FAILURE - CAR STALLED WHILE SLOWING ON A MAJOR INTERSTATE, CAUSING MULTIPLE NEAR-COLLISIONS. AUDI IS AWARE OF THE ISSUE AND THE DANGERS OF THE FAILURE, BUT HAS NOT ISSUED A RECALL, EVEN THOUGH THEY HAVE ISSUED MULTIPLE TECHNICAL SERVICE BULLETINS REGARDING THE ISSUE AND ADMITTING TO FAULTY PARTS CAUSING THE FAILURE. IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS INJURED OR WORSE DUE TO LOSING CONTROL OF THE VEHICLES ACCELERATION AND USE OF ENGINE.”
