My 2010 Audi Q7 has a serious braking issue. When the engine is started, if you put the vehicle into drive, it will roll forward and the brake will not stop the rolling. You must wait roughly 1 minute for the vehicle to not roll. The time is shorter in the summer, and longer in the winter. The brakes do not work, and it is as if the computer has a glitch. I will depress the brake, and the vehicle will roll forward about 10 feet. This happens in both reverse and forward. My concern is that one could start the car, immediately put it into gear, and hit a pendestrian, child, or other property and not be able to stop the car unless they intuitively know to put the car in neutral or park, which most drivers will not do. I am willing to show this to an NHTSA representative. I believe this needs to be investigated and Audi needs to recall these cars for a proper fix. I called Audi's North american hotline to report this, and the receptionist did not put me in touch with a manager or a safety representative. She said the car needs to go to the shop and be repaired. My auto mechanics say they can't repair this, and it is a manufacturer problem. Audi North America staff should have taken my information, passed it to a manager, and contacted me, but they refused to, saying it was a mechanical issue with my vehicle. I have no other options but to contact NHTSA. I have owned this car since 2014, I first noticed the problem then, and adapted to this problem. I should have told you much sooner than now. I apologize. I know how to deal with this problem, but if it is in any other Audi, there may be pedestrian injuries or deaths.

I have an Audi Q7 2010. June 2013, my husband, 4 yr old son and I were driving on the freeway going with the flow of traffic. The car started shaking violently and decelerated to 20 miles per hour. My husband pushed the gas pedal over and over and the car would not speed up. Luckily no one was hurt, however we were very scared. We were able to pull to the emergency lane and make it to the Audi dealership close by. January 2014, I was heading to pick up my son from school and the car started shaking violently again- this time worse then before and came to a complete stop in the middle of traffic. The steering wheel locked up and I was stuck. The police were called because I was not in a safe place and the car had to be towed to the dealership. Dealer stated that they found fault in the fuel system, metal shavings in the fuel filter in additional to low fuel pressure. Also confirmed metal shavings in the N290 valve. They had to get authorization from germany to replace entire fuel system. July 2014- yes it happened again. This time my husband and son were headed to go on a father-son camping trip and right before they lost all cell service the car started violently shaking again and decelerated. My husband left the car in a safe place and had friend come get them. The car is a lemon. I have asked that Audi America to replace the car and they sent a technician to the dealership who replaced the fuel filter again and has decided the car is repaired and safe to drive. This is after the manager of the service department told Audi America that the car is not safe and recommended they replace the car. He said " I wouldn't let my wife drive your car". this happened to a friend of mine with an Audi Q7 and Audi had to be forced to an arbitration. She ended up with a new diesel and it happened again! she is now on her 3rd Audi. This time no diesel.

As driving onto the highway, when accelerating to get to highway speed vehicle lost power went into limp mode and was not able to accelerate. Was almost rearended by tractor trailer because of this ( had to pull onto the shoulder to get out of the way). Also the glow plug indicator light started flashing and check engine light came one. Took the car to the dealer ( Audi of fairfield ct) they found that there was a problem with the hpfp metal shavings in the fuel system and they have to replace the entire fuel system. They also said that it might be from putting gasoline instead of diesel fuel, but I am sure I have always used diesel as I kept all receipts from gasstations. They will replace the entire fuel system at no cost to me, under the warranty, but I think it is a problem that needs to be addressed! thank you
