I know I've seen a post on this forum before about the vibrations when accelerating around 50-60. Did anyone find a definitive reason for it? It doesn't usually start up until the car is good and warm (driven about 20 miles on the highway, usually). We replaced one of the CV joints (driver's side) and it didn't help at all. In fact, it's progressivly getting worse. We just bought the 07 a month ago and have put about $500 into it already. Ball joint, tie rods (then had it re-aligned), bent rim, then the check engine light came on. It was the cam sensors and then the actuator. Those have all been fixed and now we're still dealing with the vibration. Any advice or experience would be very helpful! It's a great looking car and I'm really excited to drive it more once we get all this fixed. It has about 90k miles on it and we bought it privately, for what it's worth (not that I'll ever do THAT again ).
