On April 12 I exited my drive onto the 55 mph highway in front of my house when suddenly the car began to shudder. I jammed the gas to get up to speed to prevent oncoming cars from hitting me which made the problem much worse. It was violently shuddering and wouldn-??t accelerate. I took my foot off the gas which stopped the shaking. I gassed it slowly and I could accelerate to speed much slower than I would have liked. It wasn-??t smooth. One half mile later it suddenly and violently began again. Taking my foot off the gas it smoothed out and I could accelerate again. I changed plans and went to the service garage to see what the problem was. It seems the problem is a known issue that hasn-??t been addressed. I-??m glad there were no cars coming from the opposite direction which could have impacted the drivers side while I was floundering out of my drive. I will enclose the garages assessment.

Transmission intermittently would stay in 5th gear and not shift -- limp home mode. Dealership replaced output shaft sensor and turbine sensor, and this resolved the problem.

While driving last week my wife noticed that when turning into a parking spot the steering stiffened up and had to make a sudden stop as to not hit the vehicle to her left. I checked the car out and noticed it is mostly affected at low speed while making turns either left or right this had no warning and could be very dangerous.it is just luck that a walker or jogger were not on the streets at the time.this needs immediate attention I will attempt at repair myself as it is out of warranty possible rack and pinion also transmission slippage at times.

Car would jerk going interstate speed of 70mph. Felt like it was going into neutral and back in to gear. Did this about four times and I mean it is hard, will scare you to death if your in the car. After it did this about four time over an hour, the traction control and service light came on and stayed on the rest of the trip. This is a used car I just bought, so im not sure if it will continue to do this. But I am afraid to drive it on the interstate now.
