“5 times in the last 6 months the glow plug indicator light has come on and the vehicle experienced a loss of power. Twice the car completely broke down, twice Audi could not replicate the error code, the last time this happened I had just picked up the car from Audi after it was repaired. The glow plug light came on and it went into limp mode where I experienced a loss of power as I was getting on the freeway, almost got hit as I couldn't accelerate past 35 MPH.”

“My vehicle completely shut down while I was driving it 60 MPH behind a semi truck and between two cement barriers. I have it on video, it is one of my problems I had with my car to say the least. It happened once more while I was not moving, had it in the Audi dealer for the second time. After I brought it home, it wouldn't shut down. I also have that on video. The videos are too large to upload, but everyone that drives an Audi should see these. I am glad I am alive to tell my story.”

“After buying my new 2015 Audi Q7 on 9/27/14, I started experiencing hesitations when pulling out into traffic from dead stops. The very first time it happened I was in the median of a 4-lane highway waiting to turn left into traffic. I pressed the accelerator it started into the lane of traffic then stopped. I sat there for about 2-3 seconds before it took off. I expected to get hit. It wasn't the gas nor me. I have been driving for 38 years and driven over 20 vehicles and have never experienced this before. …”

“Per Audi dealership and fidelity warranty, cleaning of the secondary air ports are not considered essential enough to be covered by the extended warranty. I was given the reasoning that cleaning is not considered a failure of parts; and therefore, does not meet warranty coverage requirements, although it does illuminate the check engine light and is deemed critical by the Audi technician.”

“The car constantly needs to get oil. It is unreal that I went for a top off and the next day the oil light is on. The car has always been serviced by the dealer's service center, however no sense is made about this problem. The tail pipes show black that gives proof of oil burning no signs of oil leakage over the hood. I think this is a hazard that could only be after the damage is done. I have had to get oil put into the car thrice within the same week.”
