Power steering completely stopped working one morning. Took the car to a mechanic to have him tell me that the rack and pinion needed to be replaced. Spent over $600 to get it fixed only for him to tell me it was not the rack/pinion that was the issue..... I replaced the fluid and that is not the problem either. I have been hearing of a lot of TL's having the same issue. I wish it was a lot easier to trouble shoot this.
