I purchased a 2016 Suburban LT 4x4 last night. Love everything about the vehicle except for the buffeting which I did not notice on my short test drive. I only noticed it when I hit the interstate and headed for my hotel (working out of town). I am supposed to take the vehicle back to the dealer on Thursday to have a leveling kit installed. I was browsing this forum last night and saw all the complaints and on the buffeting and it looks like there is no fix in sight. I have to go back out of town today so I can't take it back to the dealer. I have about a 3 hour drive so I guess I will see just how bad it is. I only have about 35 miles on it so far. I welcome any suggestions on what to do from here.
