Example complaints

“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.”

NHTSA complaint #11270534, filed 2019-10, 64,000 miles

“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. …”

“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. …”

“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.”

NHTSA complaint #11256706, filed 2019-09, 65,000 miles

“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. …”
