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.

Upon having 3 consecutive oil changes, my car suddenly began to burn oil (no leaks) after the first oil change upon driving less than 900 miles. Then the second oil change did the same thing upon driving under 300 miles. It actually ran out of oil totally. I added oil as instructed by the car, and it burn the oil withing 250 miles of driving. I took it to the dealer, who acknowledge that this model and year had the wrong engine put in the vehicle. They would need to replace the entire engine at my cost, with possible reimbursement to me. Not acceptable, since they acknowledged the defect. Oil continues to burn at a very high rate and potential cause additional engine problems while driving.

Takata recall I've noticed on most of the complaints I see that the Audi A4 has a problem of jerking after it is isolating in traffic. My car jerks after sitting still in traffic, and then once I press to accelerate the car jerks. Could you please fix this problem on the Audi A4? I took it to the dealer and twice and they say that there isn't a problem.
