I purchased a 2014 Audi A6 2.0T Quattro premium plus on November 15, 2024 with 99,141 miles. I got the 14 day dealership extended warranty, which covered powertrain systems. After 3 days of driving exactly 103 miles the oil light came on my dashboard telling me that the oil was low. I immediately brought it back to the dealership and their mechanic look at it, he said there was nothing wrong and changed the oil so it should be good now. I drove it another 3 days 136 miles this time, and the oil light came on once again. Brought it back a 2nd time to the dealership’s mechanic. After about a week, we heard back and they told us he still couldn’t find anything wrong, but agreed that for some reason, the engine is consuming oil more than it should be. At this point we go to an actual Audi dealership where they tell us that the pistons and turbo were the problem so they would have to rip apart the engine and seal everything back up. At the time we purchased the vehicle on top of the 14 day dealership warranty we also purchased an extended warranty by a company called integrity warranty LLC. Our warranty company decided that they were not going to cover the cost of the parts and labor in order to fix my Audi, because they said it was a pre-existing issue prior to us purchasing the vehicle which we had not heard of before, or even seen on the Carfax report. On February 25 I was driving at night 25 mph and I came to a red light stopped my car and began smelling a very strange smell. Saw a lot of smoke coming from the exhaust in the back, the dashboard lights began flickering, the steering wheel start to shake, and then the car just shut down. Now I am without a vehicle, the dealership will not help us, the warranty company will not help us, and I now have to purchase a new car while still making payments on the Audi that doesn’t work.

I have recently purchased my 2014 Audi A6 in Honolulu at JN Autogroup. After just a couple days of driving the vehicle I have noticed that the car started to smell like gas in and out of the vehicle. The smell is very potent and very sensible throughout every second of driving and I am reporting this because this could be very hazardous and I may not know if it could catch on fire with the amount of fumes that is lingering around. To the point where as I am driving it is making me dizzy. I have researched about issues for these cars with the same year, make and model and I have read that there was a recall on the fuel line leak but i don’t know why my car wasn’t included in this recall base of the data I have pulled up on the Audi recall center. I’m not sure if it has been recalled but the problem for sure wasn’t solved with my vehicle. On the other hand, I have also noticed that the reverse camera on this vehicle goes for a split second on the dash whenever in reverse then suddenly blacks out the entire screen. I am thinking that the wiring or some kind of harness that operates the reverse camera is not done properly by the factory that causes malfunctions within the system. In conclusion, these are two of the reasons why I am completing this incident report because I feel that these are two hazardous features that is important for not just myself but the community and people that surrounds me whenever I am on the road behind the wheel. It is important for this to be resolved because the company of this vehicle advertises all these features and sells this product but there is an issue with the product and I want it to be looked upon and not swept under the rug because I am not only speaking for myself but for the many thousands and thousands of these car owners that is on the road today who are having the same issue as I do. I’d appreciate your service if this can be fixed, thank you!

IN THE SUMMER MONTHS, MY 2014 AUDI A6 DEVELOPS FUEL-LIKE FUMES FILLING THE CABIN AND TRUNK. THE FUMES BECOME MORE INTENSE/PRONOUNCED WHEN I ACCELERATE FROM A STOP OR WHEN MOVING THROUGH TRAFFIC. SEVERAL TIMES IN 2019, MY AUDI HESITATED THEN STOPPED TWICE IN TRAFFIC. ONCE ON A CITY ROAD AND THE OTHER TIME ON THE LEFT LANE OF A HIGHWAY. AUDI SERVICE DIAGNOSED A GAS PUMP ISSUE. HOWEVER, A REPLACEMENT GAS PUMP DID NOT FULLY PREVENT GAS FUMES FROM DEVELOPING IN THE CAR. I BELIEVE THIS IS RELATED TO NHTSA CAMPAIGN ID 17V781000/VOLKSWAGEN 20AR. BUT, I'VE BEEN TOLD OTHERWISE FROM THE DEALERSHIP AND YOUR SITE. *TR
