SUSPENSION
Owners of the 2020 Chevrolet Blazer report issues primarily related to the suspension, specifically involving the ball joint and control arm on the left side seizing, which can lead to axle shaft snapping and wheel misalignment.

Complaints highlight that these problems can manifest early, with one vehicle having only 1,300 miles. The described issues pose significant safety risks, including potential loss of control and vehicle non-drivability.
