I need some advice with my 2008 GP with 37K miles on the dash. I have this high speed vibration issue going on for a few months now. The car has been to the dealer twice, yet they can't seem to find any problems with it. The vehicle has had new tires, brakes, and the RF hub replaced. No rims are bent (they're brand new too). I suspect the CV shaft, but the dealer claims they are fine. I am taking the car back to the dealer on Tuesday so they can have another look. The car shakes between 60-70mph and during hard acceleration. Also, the vehicle has had a shake between 40-50 mph since it was brand new. I complained about it early on and the dealer claimed that was a normal vehicle characteristic. Anyone here experience similar issues with their GP?
