I have a 2015 LT Suburban as well. We have had multiple sets of Wheels and Tires (20" and 22") all balanced and still have a terrible vibration in the rear (feel it in the seat) when we approach and pass 70 mph. It seems to change with the road surfaces but it is always there. We bought our Suburban used with just under 50,000 miles and never test drove it on the highway. This issue has been present since day one. Has anybody heard of any updates or possible fixes?

 

Welcome to the forum.

U-joints, drive shaft, wheel bearings.

 

Thank You,

Are any of these warrantied or part of the original vibration problems mentioned above? In other words is this something GM will take care of or help take care of or will this all fall in my lap?

 

Should be covered under the 3/36 or the 5/50 powertrain warranty if they still have that.

I am having these same issues with my Tahoe. The vibration makes it very uncomfortable with my family in the car, and towing our Skis. Has anyone found any resources in fixing this issue through dealer warranty?
