“I have a 2018 GMC Sierra 1500 that I bought new in Oct of 2018 and it now has 15,756 miles on it and was still like new at the time of failure. On May 23rd I was driving the truck when the driver suspension suddenly had an structural failure (mostly the ball joint coming out of the control arm) causing the front right side of the suspension to collapse while driving. This caused the truck to go left of center into on coming traffic resulting in a traffic accident.”

“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. …”
