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

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.

Two months into owning the car, my turbo failed. Car was towed to dealership and are trying to charge me 11,000$. 2 weeks into owning vehicle. Noticed oil level at minimum. Call dealer and was advised to add oil. Never was told to come into service to have it checked. Upon further investigation, I had found out first week of august about recall. While and prior to purchasing. Dealership never informed me about any safety recalls. Previous owner had put on some aftermarket parts, which have nothing to do with faulty manufacture part. Oil strainer in turbo had failed and caused turbo failure. Dealer personnel have stated -??There is nothing we can do for you. Your car is not eligible for a recall repair.-?? Whilst Audi of America had stated that it is a manufacturing fault and they should repair and inspect. My car has been at the dealership for over a month, has not been touched, nor inspected for this. Was told today 08/17/2022 to return the loaner they had given me and -??pick up my car-?? which is not operational at all. Have tried to reach out to the dealership numerous times, and am not received any calls back until today 08/17/2022 to retrieve my car. I have been treated rudely, and have been lied to and misinformed by Audi of Naperville Illinois since the day I purchased. Was verbally told my car was certified with warranty, but now all of a sudden, there is no certification. Sales man Amin had sold me the car. Was told by numerous Audi dealerships this car should not have been on the market. General manager Michael Margas has not been willing to compromise or come with a solution. Only solution was to give me 18 thousand for my car to trade in and a 900$ payment a month on another car which is 300 dollars more than what I have. He had also tried to give me a 1000$ -??good will-?? to repair the parts. Also was told car was serviced 2 weeks prior to purchasing. Last service was December of 2018. I have the service records printed, recall incomp..

The turbo failed while driving the car at normal speed trying to enter freeway. Luckily I was able to get the car to the side of the road safely. The vehicle has always been serviced by Audi on prescribed intervals. After researching, I found a TSB on the oil screens that feed the turbos. The dealer (Audi Miramar, San Diego) told me this is not/was not a required repair and quoted me $16k to replace the turbos and replace the faulty screen. I ended up taking the car to another authorized Audi repair center and got them repaired for $9k. Audi needs to address this before someone has an accident.

EPC light and Engine light keep coming on and causing the car to go into limp mode while driving on highway at 55+ mph. This has happened three times. Each time I have taken the car back to Audi Marietta Jim Ellis. Each time I have paid thousands of dollars to remedy the problem. But other issues with the car engine keep arising. I have replaced the entire suspension at 60k miles... and Air struts at 70k. Engine mounts, Transmission mounts, replaced the battery twice. Dealership can not understand why the components are wearing out prematurely. The car is a safety issue and at this point I am fearful when I have to drive the car. This car is a lemon! But Audi will not buy the car back.

During a 500 mile road trip from ia to mo I experienced the first symptom. I was about 5 hours into the trip, cruise was set at about 70mph. All of the sudden a 'shudder' went through the car, like the car completely lost all power for a moment. Gets your attention in a hurry! I checked all the gauges, and there were no errors and everything appeared in order. We were about 15-20 minutes from the destination, so we decided to see if we would have any trouble making it. We made it the rest of the way down without incident. The next day we had to drive back to ia. In general the car drove okay. Although we did experience the shudder about 4 time on the trip home. I was surprised that we made it, based on the first shudder. Once I got home I decided to inspect the turbos, as they have a failure history in these cars. I used a borescope to check the turbos. The passenger side turbo had oil in the intake, indicating oil was leaking from the turbo compressor seal. There was also slight scraping of the compressor blades on the housing, indicating the initial stages of failure. The car was parked until I could get a chance to pull everything apart. This weekend I pulled the car apart. I found a plugged turbo oil screen buried deep in the vee of the engine. The original oil screen was deformed in the direction of oil flow, indicating the restriction to flow that it had created. I have attached pictures of the existing oil screen and a brand new oil screen held up to a light. This is to indicate the level of blockage on the original screen. Car had 91,828 miles when it was scoped. I have owned 16 Audi's over the years, 9 with turbos. This is my first turbo failure ever. I have taken many of the cars up around 200K miles, with a few surpassing it before being traded.

My specific year model 2014 as well as all 4.0tt models 2013-2014 have a well known issue in which, by faulty design, the oil supply to the turbos is restricted therefor causing the turbos to fail. The flawed design is in relation to the oil screen that clogs and starves the turbos of oil and causing failure. Audi has since began installing a revised version of this screen to alleviate these issues in models after2016. But they have ordered a recall for year models 2013-2016. Even with service intervals cut in half(oil changes at 5,000 miles instead of 10,000 miles) it is still a very common issue. When the turbos fail the engine is unable to run and can pose a serious danger to the driver as well as other motorists on the road. Not only is this a real and serious safety hazard, the cost of the repairs to replace the turbos(due to a design flaw) is upwards of $6,000 conservatively. Audi has released an extended warranty to cover the repairs of the oil separator to 100,000 miles, but this only addresses part of the problem. Many times by the time the oil separator is flagged by the ECU, the damage to the turbos is already done. On top of that if the turbos fail due to the oil separator or due to the oil screen clogging, the only repairs and costs covered under the extended warranty are for the oil separator itself. For example, if my oil screen clogs(which leads to no cel) or if my oil separator fails in turn causing to turbos to fail, the only thing covered by warranty is the oil separator. The extended warranty also is also only allowed to be used after the item has failed and not preventatively. If these items were to be covered and replace preventatively the turbos would no longer be failing due to this issue. This is a very well known issue in the Audi 4.0 community. Through Audi forums and facebook groups it is apparent this is not a small issue.

Suspension was replaced at 40,000 miles do to normal wear and tear. That was Audi excuse. Suspension was replaced again at 63,000 miles. Engine mounts and transmission mounts were replaced at 63,000. Now at 75,000 miles, engine camshaft has failed and almost caused me to lose control of the car. Oil is changed every 3K miles and all maintenance is up to date and always done on time or before required. Car always smell like gas. Inspection found no issues. At this point, I am concerned with the safety of myself and my family because this car is a daily driver. I have contacted Audi of usa for assistance. But Audi is unresponsive. I have all service records but unable to upload due to file size restrictions.

The turbo charger bearings broke and destroyed the entire engine. The car only has 64,000 miles on it, I have since heard of many other people having this problem. The estimated repair bill from the Audi dealer was $48,000, yes that's not a typo, $48,000 is way more than the car is even worth. We still owe $30,000 on a car that is essentially worthless without a running engine and is too expensive to fix. I believe Audi should do something about this since this is a known issue.

Turbo failure - car stalled while slowing on a major road. 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.
