While driving there was an internal failure of the front differential which caused debris to fly out and the debris then punctured the transmission according to the diagnosis on an Audi dealership. The car jerked to a stop and would not move. If this happens at high speed it represents a sever safety risk to the occupants. The vehicle has been inspected by the manufacturer and insurance representatives as well as by a dealer. There were no warning lamps, messages or other symptoms and this happened with no warning.

My brand new car stalled in the middle of traffic; as I proceeded to step on the gas peddle after yielding -- the car completely stoped as is I hit a wall, it jerk roughly and completely stopped. At first I thought someone rear-ended me, but that wasn't the case, the car just stalled, and the "Audi Pressure Sensor" warning flashed across the screen in Bright Big Letters for a few seconds, and once the waring went away, the car turned back on. This event happened twice, about 40 days apart. My life was at risk because if I was on the expressway, the complete stop of vehicle could have cause an accident. The car completely stoped, it doesn't slow down, it just stoped roughly, very dangerous situation. I called the dealer and I have an appointment in 2 days, meanwhile I won't take the car on the expressway, or drive it if I don't have to. I'm frighted the 3rd time I won't be so lucky and someone may hit me from behind.

Driving on a two lane busy road, car started to jerk and shut down. Lost steering capability immediately, car veered toward ditch, stopped. Called 911 immediately because the road was busy and cars could not safely get around my stalled vehicle. I told 911 that I was exiting the vehicle for my safety. I could not restart the vehicle. There were no warning lamps or messages or symptoms alerting me to a problem UNTIL after the occurrence. I had no idea what was happening, and it was frightening. Never had this situation with any of my Audi's and I only have approximately 41,000 miles on it. After about 15 minutes a person stopped and was able to restart my vehicle (911) never got to me and I cautiously drove home. Called the dealer and had it serviced immediately. Diagnostics performed on it. It required a replacement of the fuel pump and fuel rail sensor. It found fuel pump control module to be shorting out. It seems that this type of issue should not be occurring on the vehicle with such low mileage.

Car is feeling jerky and shaky at the steering wheel when driving or sitting still. Very common problem on these cars. Will probably need new steering rack. This issue needs to become a recall. Very frustrating.

Vehicle has 73,000 miles and the transmission has severe juddering. Transmission jerks continually while driving at all speeds, and makes it unsafe to drive. Apparently a common problem with audi's. Fix is $6000.00, making car worthless.

As I accelerate from 0 to around 2k RPM, car jerks rapidly and then continues to fix itself to be smooth. Even on 55mph speed and I decide to press the accelerator down quite a bit, the car jerks again.

I have the a4 w/ 3.1 liter v6. Almost immediately after purchase, transmission exhibited bumpy lurching start from stop. Audi diagnose said that's symptomatic of this transmission and engine combination. Nothing could be done to prevent. Within 1st year, the car would stall and completely shut down, necessitating a re-start. Sometimes upon start, and most notably (and the example cited above) when driving at slow speed. (I suspect the stall problems described relates to the lurching transmission problem). On this incident there was no check engine light. Took to audi, they couldn't identify problem. I took to an independent -- they determined problem as fuel pump. Replaced fuel pump. Most recently the car stalled when initiating a left turn from a slow 10-15 MPH roll. As I slightly depressed accelerator, car stalled in middle of left turn -- had to re-start mid-turn to restore power steering and finish turn (turn was down a slight incline so car was able to coast). This happened around 2/15. I took it to audi, the following day. They said because there was no check engine light they couldn't diagnose. I called audi USA -- they offered no solution or database research of problem w/ other audies. A similar occurrence was 8/14 when I exited freeway and as I rolled to a stop, @10-15 MPH the car stalled. Had to be restarted. No check engine light. I may have taken to dealer but don't recall. My concern is the safety risk if this occurs with my wife driving and an oncoming car is unable to stop if the vehicle stalls in similar manner in the middle of a left turn. Could cause serious accident.

While at a complete stop and attempting to accelerate, the vehicle would jerk. The vehicle was taken to an independent mechanic where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 100,000.
