I have a 2017 GMC Yukon Denali I have experience the rough ride the bumpiness and I kept taking it back and they kept telling me it was tires I said this is more than tires please check this out they finally decided to tell me that the shocks were locking up and $3300 to replace 4 shocks.
after getting on the Internet and find out it's not just the shock but the suspension. GMC has known about this for years. This is an ongoing problem for them. This is an expensive endeavor after paying $70,000 for a car 3 years ago as my retirement car I find it this is totally unacceptable. not sure, if i want to keep this car. The car is in the shop mow October 2020. Not sure how to handle this one.
