After shopping, I was driving my sister back to her house, pull into the driveway, put the car into park, (hear it click ) engine still running, started to unload the packages, when the car started moving forward, when I got into the front seat, I place my hand on the transmission stick, to make sure it was still locked, and at that point the front of the car, raised up, and accelerated, hitting a tree in front of the house, if it wasn't for that tree, the car would have hit the house. Call Audi the next day, during the next week, Audi technical field manager, looked over the car, and found it to be operating as designed and intended, as per letter dated Oct. 5, 2006 from Audi executive office. For the record, Audi of smithtown service reps. Went above and beyond to help me with this problem, and by no means does this reflex the dealership. This problem needs to be address and corrected before someone gets serious hurt..

On 6/25/05 I purchased a new 2005 Audi A6 3.2 sedan from Audi of oakland ca and have recently become aware of a potential hazard. Audi national customer service states that the condition of my concern is common to all Audi A6 vehicles with automatic transmissions. Depending on the particular driving conditions and without warning the vehicle can temporarily fail to respond to pressure on the accelerator pedal. This usually occurs after a sharp deceleration followed by an attempt to resume speed that calls for a change of gearing. When this condition occurs there is an approximate one to two second delay when there is no engine power. After the delay the engine will lurch in to power upon finding a lower gear. The problem came to my notice when I attempted to move quickly out of an intersection with traffic bearing down from the side. It was a frightening experience as for that brief period there was no engine power and I thought that the oncoming vehicle would hit me. I have discussed this potential hazard with the dealer and with Audi national customer service. Their reply was that the response delay is ''normal operation for the vehicle'' and further that Audi does not consider a need to remedy this design defect. Since then I have tested a number of other vehicles in the same class made by other auto manufacturers and none of them have this defect. I ask that you investigate this problem and that you use your authority to make Audi fix this defect and issue a recall. Thank you for your consideration and assistance.
