Ok this is a little long but please bear with me. When I test drove the car, before I bought it, it had a vibration in the steering wheel. They promised to fix the issue. When the car sits for an hour or more I get really bad vibrations to start then it smoothes out a little bit. The vibrations will come and go while driving. The first trip in I was told it was 2 bent rims in the back. So they replaced the. As I drove off I still felt the problem. So I took the car back to them the next week. They said I had a bent from left rim. Well when I drove off I could feel the problems were still there. So I took it back a 3rd time and they told me it was a out of balanced rim on the front left rim, the one they just replaced. When I drove off I still felt it. So the next day I called in and they came and picked the car up. I got a call saying the car rides like any other TL on the lot. So I went to pick it up and we test drove the car and it showed its ugly head of a vibration again. This time they kept the car and a week later said it was flat spots on the tires. Well I talked them into replacing all 4 tires. When I picked it up the tech drove and said it felt fine and I couldn't tell. Well the next day I felt it again. So here I am still vibrates with 3 new rims, re-balancing tires and all new different brand tires and I still have a problem. I am wondering if anyone might have a clue where to go from here. It seems the temperature outside does not effect the problem. You notice the vibrations more when you are going 68 or higher. So any clues what to tell them to look at or is this natural as they say it is? Thanks!
