"Extremely bumpy ride on the slightest bump in the road. Well known problem with Yukons after 5-6 yrs. Happened in August 2024. Replaced all 4 shocks and struts"

Anonymous A., NY (2018 GMC Yukon Denali 6.2-L V8)

""Both front shocks froze up and the ride became too stiff to even drive the vehicle. It was an emergency situation that cost $3,900+ to repair. Not happy at all about it for no better ride than this vehicle has. Hydrodynamic suspension is overrated by 100%.""

Other/unsure

"I had it winterized with after market parts. In Alaska it's required if I didn't want my SUV to freeze. They consisted of three heaters in the engine compartment. The engine started heating up so I took it to the local dealer. The block heater was leaking antifreeze. They replaced it with a GM part and all is good"
