I own a 2024 Chevrolet Silverado EV WT equipped with the OEM soft tonneau cover. The original cover and its warranty replacement have both failed in the same way. The cover material appears to shrink over time so that the side flaps will no longer reach and stay attached to the Velcro along the bed rails. At highway speeds the cover flaps and “balloons” upward, and the Velcro strips will not stay connected even when properly installed and tightened. The dealer has already replaced the cover once under warranty, but the replacement has the same problems. This suggests a design or materials defe…

On 1/20/26, we purchased a ‘24 Chevy Silverado EV from a Chevrolet dealership. 2 days later, on 1/22/26, while my husband was driving on the interstate, the tonneau cover partially detached and flew backwards lifting upwards and flapping violently. One of the metal crossbars detached completely from the tonneau cover and flew off the truck, and a second crossbar began to tear away. The cover was flapping forcefully which created a highly unstable and dangerous condition. My husband pulled over on the side of the interstate to remove the tonneau cover to prevent it from fully detaching. He pla…

Oct 2, 2025Steering
Under heavy acceleration the vehicle swerves from lane to lane and the operator is unable to counter the steering. The behavior continues until the acceleration is halted. The vehicle was grounded due to it being deemed unsafe by the originating dealership technician and repairs were attempted but were unsuccessful. The dealership had another vehicle like mine in inventory so they tested that one and found the same erratic behavior but rather than deeming it to be a problem they declared the steering issue it to be normal for that model. This is section 4 of the attached dealership service rep…
