ABS sensor failed. Caused the warning lights to come on showing failure. The rear brakes locked up in an intersection as a result of sensor failure and I narrowly avoided a serious accident. This has happened twice. Each time when a sensor failed.

Breaks squeal

- Oakdale, MN, USA

Problem is the brakes. Six months after purchasing this SUV, the brakes started to squeak a little when I slowed down or stopped. It would come and go, about 2 months after, it happened more often, but I waited since I had a maintenance coming up. I took it in for maintenance about 5,000 miles, mentioned it to the service attendant and he told me they would check. I picked up my Audi I was told they did not find anything wrong with my brakes. At that time the attendant mentioned that other Q7ʻ's had something going on with the brakes, but not my Q7. I did not hear it for a couple weeks and then it started up again and off and on. Finally, it got so bad I took it in on Oct 24, 2016, they called me to tell me that they could not find anything and I insisted there was a brake problem and I was afraid that the brakes were malfunctioning, so they asked me to come in and take it for a test drive with the service attendant. We went for a drive about 2 to 3 miles and when I stopped in the parking lot at the end of the street, lagoon drive, it squeaked a little and he heard it, then we drove back and when I slowed down to make the right turn into their street to the service department, attendant heard the squeak again, so he said to leave it another day and they would check it out. Still could not find anything, but they cleaned the brakes and whatever and said I probably ride the brakes, that was that. Picked it up on Oct 26, 2016, it seemed ok for a day and then it started up again worse than ever! so took it in to service on Nov 23, 2016, checked it on Nov 28, 2016, found nothing wrong with the brakes, conclusion, I ride the brakes! spoke to the GM jeff lee and will not repair unless we pay for it! I have owned at least 20 new autos, this never happened before! frustrated and feel cheated!!! spent almost $90,000 with all the extras!

Wife was pulling into a parking space and she depressed the break pedal. The pedal went straight to the floor without stopping the vehicle. The car (Audi Q7, 2015), continued to move forward until she hit the car parked in front of her. She quickly let off the break pedal and re-applied the brakes and the car stopped; although, this could have been attributed to the impact. Luckily this happened in a parking lot; however, now she is concerned that this could happen on the road at higher speeds. She took the car to the dealership, where they told us that they called corporate Audi about the situation and that they sent experts in to evaluate the car, who found nothing wrong (I guess the experts were able to come in and evaluate the car within 12 hours, as we dropped the car off after 5pm and they told us the next day that they could not find anything wrong with the system). They stated that there was nothing they could do since they did not find anything wrong with the car. This does not change the fact that it happened.
