2021 Chevrolet Silverado suspension problems

The failure pattern owners describe
Owners describe two categories of suspension issues: catastrophic failures and unresolved noise.
Ball joint and control arm failures are the most serious. Multiple owners report front suspension ball joints separating or fracturing at highway speeds (37,000 to 98,000 miles), causing the vehicle to pull hard to one side or lose steering control entirely. In one case, the wheel folded underneath the truck after a ball joint failed; in another, a driver lost control at 43 mph after a "Brake Failure" message appeared—the underlying cause was a fractured upper ball joint. One owner reported complete structural failure of both front control arms at highway speed, resulting in over $4,000 in damage. No warning lights preceded these failures.
Shock absorbers are leaking fluid. One owner reported both front shocks leaking; a replacement passenger-side shock installed on 11/28/23 leaked so badly it pooled in the driveway the same day.
A persistent clunking noise from the rear suspension troubled another owner starting at 1,020 miles. Despite two dealer visits and tickets sent to GM, the source went undiagnosed—a TSB existed for 2020 models but not 2021s. One owner also reported violent bouncing and pitching over bumps from day one of ownership, causing loss of control on rough roads.
These are unverified consumer reports filed with NHTSA.
