Consumer Description

I am writing to formally express my dissatisfaction regarding a significant safety and reliability issue with my 2020 GMC Denali. Specifically, the vehicle is experiencing premature wear and imminent failure of the front ball joints. I expect the suspension components of a premium Denali-trim vehicle to last significantly longer than the 37,061 miles currently on my odometer. Industry standards typically place the lifespan of these components between 70,000 and 150,000 miles. Technical Details of the Failure: The vehicle is currently exhibiting the following symptoms of accelerated ball joint degradation: •Excessive Vertical and Lateral Play: Inspection reveals play in the right lower ball joint that exceeds the manufacturer’s maximum allowable wear specifications. The left lower Ball Joint is starting to have a small amount of play, according to the technician
