While backing up, image of rear view and overhead camera froze. Image showed a clear area behind car and I continued to back. I backed several more yards and hit thick underbrush before I realized the image was not accurate. I cut off car and restarted and image still froze. There was no damage from contact with brush but there was a large tree within 2 feet of the car's rear.

Cpsc: While being driven by my brother-in-law with my sister as a passenger, my 2017 Audi Q7 caught fire and was engulfed in flames in a matter of seconds. The fire was proceeded by a sound, and the fire seemed to come from front passenger side. It was not struck by anything and did not run over anything. The consumer stated the vehicle was previously repaired due to a fuel leak.

Pre-sense sytstem nearly caused accident on two occasions where there was no reason for it to stop the car. First time was at 75mph, on calif. 46, 4 lanes divided, westbound about 25 miles West of I5, level stretch of road, clear weather, no vehicle ahead in either lane and no oncoming traffic. Car suddenly cut fuel and braked to a stop. I was in right lane and ended up on shoulder. Fortunately, no traffic close behind or I might have been rear-ended. Audi dealer could find nothing wrong and had no explanation. System has four settings: Early, medium, late and off. Dealer set system to "late". when I asked if I should turn it off, I realized there was no way dealer would advise me to do so because of potential liability. Second incident two months later. At night, on ventura blvd. In sherman oaks, ca, at corner of kester ave., westbound at night, pulled into left-turn lane. Initiated left turn because oncoming traffic was a very safe distance, far away. Pre-sense system activated and stopped my car in the first lane of oncoming traffic. Because the next oncoming vehicle was in the second (right) lane, it did not impact my car. Had that vehicle been in the first lane, I would have been struck at 35-40mph broadside. There was absolutely no reason for the system to stop the car. I pulled over after completing the turn and turned the pre-sense system "off". this system is clearly not ready for deployment in vehicles. Rather than avoiding an accident, the system nearly caused an accident the only two times it ever activated on my vehicle.

Our Q7 is less than a year old. I smell gas when I park the car even after a short drive of about 3 miles. The idi service had said that this was related to vacuum pump and fixed it last week. I still smell gas and I am concerned with safety. I saw previous models have been recalled due to potential fire due to gas leak and I am worried that this might be the case with 2018 models as well.

After a short drive in hot Texas, I parked my car to pick up my daughter. Came back out to an empty lot and chatted with another parent in front of the car. While doing so my sunroof "exploded", nothing landed on it, and we were far from the road or any buildings. Needless to say had we been in the car and driving it would have been a huge safety concern, there was tiny pieces of class everywhere. And it said a loud noise when it happened, and I am sure that would have created issues driving 60 mph, which I did 10 minutes earlier.

When moving the car in reverse from overnight parking in my garage, the brakes squeal excessively. This sound does not occur when braking while moving in a forward direction. The car stops appropriately, but the sound it quite loud in reverse braking mode. The sunroof creeks and pops during city driving and highway driving. I just read an article on consumerreports.com about exploding sunroof problems and I'm concern that this could happen due to lack of reporting and manufacturers not taking ownership of the defect. Popping sounds coming from my sunroof have me concerned about my panoramic sunroof exploding during travel in the vehicle

Water leaks into the passenger cabin on the passenger side front floor from under the dash and puddles on the floor. The battery is located just under the floor where the puddling occurs. Audi claims this is "normal" unless I turn off A/C when going through a car wash or rain! this is a mold and electrical short hazard as water can drip down into the battery compartment. According to Audi, this happens on all Q7's per my work order receipt. This issue happens in rain, or while going through a car wash with the car running and A/C turned on and operating. Vehicle was out of service 14 days while trying to figure this out at dealership.
