   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.

    My 2018 Sierra began experiencing severe shuddering while driving down the road. The dealer said it was caused by moisture getting into the transmission fluid and contaminating it. In my ownership of dozens of vehicle's this has never happened before. This formerly inexpensive minor fluid change requirement morphed into a $618.00 major surgery just to fix a problem that should have never occured. If the fluid was contaminated by moisture as the dealer explained, it's a…

    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.
