Canuck SHO
We purchased our SHO, and we finally took it on a road trip to Flagstaff last weekend. The car has a distinct high frequency vibration that is centered around 67 MPH. You can feel it starting about 50 MPH, but it is worst at 67. The dealer's response is "it's a performance vehicle and it is normal." I can tell you after 4 hours of driving, I was ready to get out from behind the wheel. It is most noticeable in the steering wheel, but you can feel through out the car. To me it feels like a driveshaft is out of ballance.
Has anyone else had the same issue? The car is a 2011 and only has 1400 miles on it...

LOL, that has to be a joke, right........

Find another dealer who isn't into so much 'comedy'.
