1. 2010 Toyota Corolla S was purchased from a Toyota dealer with 8 miles. Right after going off the lot, and onto the freeway, car was unstable. Even if you hold the steering wheel straight, the car wants to jump left and right randomly. Basically it is unstable. 2. car is unstable and requires more than normal concentration and more effort to drive straight, as car does not track straight. 3. vehicle was brought to dealer with approximately 185 miles. Test drove with technician, who said it veers slightly right. Alignment was done. The front was off by a bit and corrected. But rear of car was out of spec with regards to left and right toe. Basically both rear wheels facing towards the left. Toyota dealer said they are unable to repair this problem. I bring in a Toyota technical service bulletin that addresses on-center steering feel. The document requires alignment done, then power-steering ECU replaced. My ECU is then replaced at the dealership, but alignment in rear is not adjusted, since the dealer said it is not adjustable. They give me back the car with the new ECU even if rear toe is off along with total rear camber. They also say that total rear toe is correct at.38 deg, but even if left and right rear toe is off, as long as total rear toe is good, car is within Toyota specifications and tolerances. I do not agree with the statement. If left and right toes are off, then car is not aligned. Right rear toe is out of spec by.15 degrees while left rear toe is off by -.09 degrees. I take the car and drive it for 1 day and a half, and the car veers right on the freeway. If it hits a bump on a turn, it usually makes the car want to jump right. Basically proving that the rear toe is out of specifications.
