I took my truck to the dealership because of my issues and they said they had many trucks going in with the same issue but there was no fix to it. The issues Popping Noise Heard On Hard Turns and/or Going Over Speed Bumps, Creaking Noise While Turning Wheel Left and/or Right, Clicking Noise Heard On Slow Sharp Turns.Also when you go over a bump the truck makes a spring loud noise to the point that the whole truck bounces. shifter is also very hard when you try to change gears.

On 22 December 2020, I received a 2021 GMC Sierra 1500 SLT X31 Truck. The day that I drove it I notice that the Truck was riding as though it had a low Tire issue. It was riding bouncy. I had no low tire light. I checked the Tire Pressure and they all was over inflated. I brought the pressure back to range, but the Truck was riding the same over rough and bumpy roads that the rear end of the Vehicle was shifting from side too side when you hit a bumpy or on rough roads. it felt like the rear end was coming off the ground very frighten. I called GM they assigned a case number and I took the Truck to Three dealership with the same answer that all bolts were tighten to Spec. Ok I get that, but did not address the problem that the truck is doing. I am not comfortable driving this truck especially when you have no I deal when your terrain will change and the back end of y0our Vehicle moves from side to sider on you.
