I have this problem too, mostly at lower speeds like you cltsig, but I have a question. Did anyone on this thread not test drive the vehicle before they bought it? I did and didn't notice it. I feel like it was a few weeks or even a month before I noticed it. Everyone who borrows and drives my Yukon says its the nicest ride, smoothest ride, most refined ride they have ever experienced. I'm always shocked because deep down I'm embarrassed when I hand over the keys. I feel like I should apologize in advance for the ride... but I don't... almost like an experiment to see if they notice it. No one ever complains, but they only drive it for a few hours.
It's my wife's daily driver and it took her 6 months to say "is it just me or has the ride gotten harsh? I feel like ear pressure or something" That's when I decided to google it and found this thread.
I'm curious......Did everyone else not notice it for a while too? I really feel I wouldn't have bought this vehicle if I had noticed the ride issues.
Thanks
