“I have a fuel leakage on the lower right side of my vehicle and as soon as I park the vehicle I can feel the fuel smell all around my vehicle. I have given my vehicle to authorized Audi dealer (bell Audi,edison) and they never said anything about the recall going on Audi vehicles”
NHTSA complaint #11299100, filed 2020-01, 58,000 miles“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. …”
NHTSA complaint #11337269, filed 2020-07, 50,500 miles“There is a fuel smell inside the car and in the garage where it is parked. In stop and go traffic moving at 5-10 miles per hour, the smell is very noticeable inside the car.”
NHTSA complaint #10822716, filed 2016-01, 40,000 miles“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. …”
NHTSA complaint #11464964, filed 2022-05“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. …”
