The vehicle steering wheel shudders at speeds from 40-55mph. The steering wheel shudders at 2-second intervals and is constant between those speeds. At first, I thought it might be one of the safety systems. It is not. This is unsafe and GM should be held responsible.

Noticed a scraping noise after new, recommended tires installed on my stock truck. Checked the door label to ensure correct tires installed, they were, returned to the tire facility and they recommended I ask a repair facility to investigate. Found that the tires are rubbing the upper control arm when fully turned left or right (both sides affected). Went online to discover that this is a common issue with the 2018 and similar GMC Sierra and Chevy Silverado trucks. This is a safety issue caused by a design deficiency. Two things can happen. One, the tire can fail. Two, the upper control arm could fail, causing the vehicle to be uncontrollable. This could be fixed by restricting the extreme left and right travel in the steering system or redesigning and replacing the upper control arm so it doesn-??t interfere with the tire. This is an unacceptable safety issue caused by a design deficiency and needs to be addressed by NTSB now.

The contact owns a 2018 GMC Sierra 1500. The contact stated that while driving at an undetermined speed, the vehicle was shaking while shifting gears. The contact stated while shifting from four cylinders to eight cylinders, the rear-end was shaking violently. The hood latch warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the tires needed to be replaced. The tires were replaced three times however, the failure persisted. The manufacturer was not contacted. The failure mileage was approximately 50,000.
