I bought my 2015 GMC Yukon Denali earlier this year. I have had countless problems. I have had the retractable side steps worked on, the 4-wheel drive repaired, the transmission worked on, and countless recalls. In addition, I have experienced the constant vibration and noise as well. They have attempted to repair this through replacing all 4 tires, replacing the exhaust muffler with resonator, exhaust and tailpipe, insulated parking brake cable, and securing sheet and replacing insulation between headliner and roof. None of these have solved the problem.
On a side note, since my SUV has been in the shop for weeks on end now, they have scratched my vehicle, caused paint transfer, and dirtied up the headliner with smudges and hand prints. This is unacceptable.
I never experienced so many problems with a vehicle or encountered so many rude employees. I should not be having these problems on a $74k vehicle, or any new vehicle for that matter. I regret trading in my Range Rover for this vehicle immensely. GM may be posting great profits right now, but that will change when people see past the new overhaul on the Tahoe/Yukon/Escalade and see it for what it really is- a poorly made vehicle.
