Car hesitates erratically and unpredictably when accelerating most noticeably from a dead stop, and at slow speeds while turning. attempting to accelerate from a stop to cross a street in busy traffic the car will just sit unresponsive for seconds and barely accelerate and then unpredictably accelerate. due to the vehicle being the r-line, it drifts all over the road. i have had 4 wheel alignments on the car with only 6400 miles on it.
