Since day 1 of purchasing new,to current date, there is vibration at idle. There is vibration at highway speeds of 60 MPH plus. It has been to the dealer 5 times for testing. This is a known problem with thousands of vehicles. Gm says it meets their specifications. The dealer balanced the tires 3 times, no luck. The dealer replaced the tires, same issue. I am told the vibration at idle is normal. This problem is distracting when driving. I have been dealing with gm and the dealer for 7 months with no resolve.

This happens every day, so ignore the date I entered below. I have videos but the file is too large to download.
