We have had to replace this part 3 times now. Once at 50k, again at 100k, and now at 131k.

I am getting frustrated with my new car and is thinking about trading it in for another one.

While at low speeds such as 15-30 MPH under light acceleration to steady driving or deceleration, noticeable engine shake as if the transmission is hunting for a gear. I believe the problem to be either (1) poor engine mounts, or (2) a software problem in the engine Control Module. I was not sure at first if only I detected the problem, but my wife has also complained.
