“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…”
