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, compromising the vehicle's stability, control, and overall safety. This defect can potentially lead to accidents, injuries, or even fatalities, both for the occupants of the Audi S6 and other road users. Financial and Non-Financial Consequences: The repeated failure of motor and transmission mounts has imposed significant financial and non-financial burdens on me as an owner. The cost of multiple replacements and repairs is high and unreasonable for a vehicle of this caliber. Moreover, the frequent breakdowns have caused significant inconvenience, as I have had to endure extended periods of vehicle downtime, repeated trips to the service center, and associated expenses for towing and alternative transportation. Request for Resolution: Considering the seriousness of this matter, I request that AUDI USA i INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATIO

NHTSA ID 11526318 · filed Jun 10, 2023

Camshaft Actuator, Camshaft positioner, Camshaft sensors. No warning or dash lights, car abruptly stopped on Highway while traveling 65mph 15 hours after Audi replaced replaced both fuel pumps and oil screen recall fix. Inspection of entire vehicle was done at time of recall fix and fuel pumps replaced. This is the second time in 30k miles that the camshaft components failed without warning. This is a major job and very expensive. Why hasn't this issue been recalled?? This is a safety hazard and a public safety issue. This could have caused a fatal accident while I was driving my family the store.

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 shorted out which is causing the power steering to be manual steering and problems with suspension when lifting. I'm mainly concerned with the power steering going out with under 70k miles and it takes a lot of effort to drive this. I shouldn't be driving the car right now, but I have not choice at the moment.

While driving, received notification of a suspension fault. Was able to drive vehicle home, and found code for suspension C104600. Cleared code, and didn't see it return. Car sat a few days, and next time it was driven, received cascade of MIL warnings for suspension auto leveling failure, auto leveling headlights, adaptive cruise, lane keeping, and auto braking. Console advised to keep speed below 35 MPH. Had to quickly exit the road as result. Limped vehicle home on side roads, found codes across multiple systems. Suspension would not raise, and all coda would immediately return upon clearing. Vehicle was evaluated by local shop, and diagnostics show failed suspension air compressor and relay.

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 REPLACED 18 MONTHS AGO, I SUSPECT SOMETHING ELSE IS GOING ON.

I WAS DRIVING BEHIND AN AUDI S6 (ONE OF THE NEWER MODELS WITH FULL LED LIGHTING) AT NIGHT. I FOUND ITS LED BRAKE LIGHTS BLINDINGLY BRIGHT. THE DRIVING LIGHTS ARE VERY BRIGHT BY THEMSELVES, BUT THEY'RE BORDERLINE TOLERABLE, HOWEVER BRAKE LIGHTS WHEN THEY COME ON ARE EXTREMELY BRIGHT - I COULD NOT LOOK AT THAT CAR WHEN DRIVING BEHIND IT, IT WAS TOO PAINFUL TO LOOK AT. I HAD TO TAKE MY EYES OFF THAT CAR AND OFF THE ROAD AHEAD OF ME AS A RESULT OF THIS FOR EXTENDED PERIODS OF TIME. I COULD NOT HAVE THOSE TAILLIGHTS WITHIN MY FIELD OF VISION, THEY HURT EVEN WHEN I TRIED TO LOOK AWAY FROM THAT AUDI. I DO NOT FEEL SAFE DRIVING BEHIND NEW AUDIS AND OTHER CARS THAT USE EXTREMELY BRIGHT LED TAILLIGHTS. I COULD HAVE CRASHED BECAUSE WHEN I WAS SLOWING DOWN BEHIND THAT AUDI THAT LIT UP ITS TAILLIGHTS WHEN BRAKING I COULD NOT LOOK AHEAD ON THE ROAD AND AT THE CAR. I HAD TO BRAKE BLINDLY WHILE BRIEFLY LOOKING UP FOR A MILLISECOND OR TWO (AND SUFFERING EYE PAIN) NOW AND THEN TO ENSURE I WASN'T GOING TO CRASH INTO IT. I WAS NOT ABLE TO CONSTANTLY MAINTAIN THE AUDI IN FRONT OF ME WITHIN FIELD OF SIGHT DUE TO SEVERE EYE PAIN IT CAUSED ME. IS THERE A LAW THAT MANDATES A SAFE LIGHT OUTPUT BY THE HEADLIGHTS? BECAUSE I FIND LED TAILLIGHTS IN GENERAL PAINFULLY BRIGHT TO VARYING DEGREE AMONGST DIFFERENT CARMAKERS, WITH AUDI HAVING THE MOST SEVERELY PAINFUL BRIGHTNESS (SIMILAR TO LOOKING AT THE SUN). *TR
