Power Train Problems of Audi Q7 - part 2

While in motion on the highway, this vehicle intermittently loses power. A warning on the dash shows "gearbox malfunction" and the vehicle goes into limp mode. Once over so the side of the road, the vehicle can be turned off, and then restarted. Once restarted, no warning lights are visible and the vehicle drives as normal. This seems to happen in the summer months rather then winter and is sporadic. Sometimes it won't happen for a month. Other times it will happen 3 times in the same trip. It is dangerous to try and get over to the side of the road in high traffic traveling 60+mph. Internet searches on issues with Audi gearbox malfunctions shows that this is a problem, but no recall has been done.

If the vehicle is in neutral gear, it cannot be placed into drive gear, unless you depress the brake. When you place this vehicle in a car wash that pushes the vehicle in the neutral gear, we are unable to shift gear to drive unless you depress the brake. Applying the brakes in a moving car wash line is dangerous. If you do not quickly change gears, the vehicle could slip the rollers and potentially cause the vehicle behind it to strike the Q7.

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 Audis, there may be pedestrian injuries or deaths.

This is a tdi version of the Q7. The high pressure fuel pump failed during normal use and sent metal parts through the fuel lines, through the fuel filter and into the combustion chambers. As a result, the engine ceased and we were left stranded in the middle of the road on a winding canyon road. The engine block was damaged; the crank shaft bent, the pistons damaged the heads and many other parts were destroyed. The car was repaired by an Audi dealer and required all new fuel components (bumper to bumper) and a new engine. The car was in the shop for over a month.
