This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
On three separate occasions, the vehicle did not stop when the brake pedal was pushed at highway driving speeds. This does not happen all the time. Car has been towed to Audi dealership twice, yet they find nothing wrong with the vehicle because the diagnostic tests that they are running rely on the computer, which is defective to begin with and not recording the necessary failure (codes) for when the brakes fail on the vehicle. We have no choice but to continue driving the per Audi dealership (open road / Audi manhattan) until lease end.
When braking the car vibrates, sometimes so violently that it is unsafe to keep applying the brakes to control the speed of the vehicle. Currently the vehicle has been in service since June 27, 2015 and has been driven 21,000 miles. However, this vibration has been noticed early in the life of the car. Originally, I thought the vibration was due to the road surface or condition, but I have come to realize that this problem is a vehicle fault. In the most recent incident we were driving from payson, Arizona to mesa, Arizona using the vehicle cruise control. On this road, us 87, there are a few inclines of about 6% that run for 2 to 3 miles. As the car gained speed going down the incline the cruise control would apply the brakes and extreme shuddering and vibration of the vehicle occurred. To maintain a safe speed we eventually reverted to engine braking to control a safe speed. This highway is very well maintained and I am certain that the road conditions did not contribute the the violent shuddering of the vehicle. My wife and I have been retired for several years and we have not driven this vehicle hard or had any emergency stops. The vibration is present, to a lesser degree, at slower speeds and varies considerably day to day. I have owned two Lexus' prior to the A8L. Both the LS400 and LS430 were driven 120,000+ miles without a brake problem or vibration during braking. The pads may have been replaced once, but the rotors never had a problem.
I was driving on a Suburban city street in a straight line with no cars or any other obstructions ahead of me or behind me. Without warning, the car engaged its emergency braking throwing my daughter and me forward violently into our seat belts. When I fell back, the dashboard was showing me a proximity warning but again nothing was anywhere near our car. The servicing dealer said they didn't find any error codes and so there was nothing they could do. This hasn't happened again (yet) but the cameras all around the car that engage for parking and in reverse are constantly going out and/or the vehicle mmi system randomly retracts into the dash while driving.
The brake and gas pedals are too close. I consistently hit the brake while accelerating. They need to be spaced farther apart, and the brake pedal moved to the left. There are comments all over the internet about this problem and Audi service says there is no fix. I have large feet and have never had this problem with any other car manufacturer. I need the NHTSA to get involved before someone gets hurt. This is a very big defect that needs to be fixed.
