This started happening in the last 2 mos. My MMI started acting up, it first displayed radio not installed, then it would stall and not show anything on screen, then it came back on to regular showing but then went out again and displaying radio not installed. Then at one point I was able to play my CDs but not my radio. Then finally the complete system went out, now the screen only shows the MMI logo and will not turn on and cant not be reset. So as this has happen, my fuel tank area started to drips tiny drops of gas only happens when I drove it, so now it is leaking even more fuel so I have it sitting in drive way until I get it into the shop. While its been sitting in the drive way for the last 2 weeks, I would occasionally start it but this last time I started it my battery went dead and it started leaking even more gas after I got it jumped. …
there is a gas odor that is overwhelming when the truck starts. the gas mix with oil fumes will cause headaches because the odor comes into the vents of the truck and does not stop until after the truck is turned off. when the vehicle is turned off there is a hissing sound in the engine that does not stop until after 15min the engine stays off. There is no overheating but the engine is hotter then most trucks when running.
The vehicle is leaking fuel like it did before the recall in 2016. Fuel puddle under car after sitting for 3 minutes huge safety problem. The recall was done 9 years after the car was sold and it's been 9 years since the recall was done and the problem came back, meaning it was never actually fixed, since it lasted the exact same time it took to break the first time.
Heard a loud "pop" then there was a strong smell of fuel coming from the engine compartments in my 2007 Audi Q7 3.6l fsi while I was driving. I stopped the vehicle and shut off the engine and did some investigation and found the leak was coming from the injector and the fuel rail. The vehicle was in motion on a busy street when this leak occurred. Thankfully a someone noticed and notified me that I was leaking something which turn out to be fuel. I was able to fix the problem with occurred on 01/19/2017 by buying a injector seal kit from the dealer. . Unfortunately I had another injector fail on me on 01/28/2017. Did some research and found there's a recall for the 2011-2015 model of the Q7. My wife uses this vehicle for her needs with 4 children inside. This is copied from the recall done with the similar issue in the newer model. …
Dear NHTSA team. My vehicle demonstrated a fuel smell in September 2020. I alerted Audi that I believed it was covered under either 20w9 or 20bj. They said it was not. I took it to a private repair shop that charged me $71 to diagnose the problem. The repair shop (team previously worked for Audi) shared that the problem was covered under a recall. I then took the car into the dealer and Audi fixed it under the recall. I sought reimbursement of my diagnosis fee of $71 for over three months. Audi failed to respond on multiple occasions when I first raised the issue, and later when I sought reimbursement. Finally, on 12/16/20 I was advised that Audi would not reimburse the diagnosis fee notwithstanding the repair was covered under the recall. They also allowed the unsafe situation to continue for weeks by refusing to repair under the recall. …
Large fuel leak in the engine compartment: while starting the vehicle in a parking lot, the engine was difficult to start but then started. The driver began to depart by backing out of the parking space, then a strong gasoline smell was present, as the two front windows were rolled down. The front passenger noticed liquid flowing out from under the front of the vehicle on the passenger side while the car moved forward by about 2-3 parking spaces. The driver immediately stopped, shut down the engine and investigated. The strong smelling liquid appears to be gasoline leaking from under the engine compartment. The vehicle was parked on the spot as the two occupants evacuated the vehicle. While outside, the sound of gasoline splashing down could be heard. A tow truck was called, and the vehicle was towed to the nearest dealership. …
