NHTSA Complaint #11707083 — 2020 CHEVROLET SILVERADO 2500

I am filing a safety and health complaint regarding a known rear window water intrusion defect on my 2020 Chevrolet Silverado 2500 with approximately 56,000 miles. Despite the severity of the issue, the dealership has refused to provide a permanent repair. This defect is widely documented and has resulted in a recall in Canada, yet no recall exists in the United States—despite significantly more of these vehicles being sold here. The inconsistency in recall coverage is deeply concerning. My vehicle experiences substantial water intrusion that has saturated the rear headliner, rear seat area, and carpeting. This creates a serious health concern, particularly for rear-seat passengers, including children. Prolonged moisture intrusion creates a high likelihood of mold growth beneath interior components, which General Motors has failed to address. There is also a serious safety risk. The rear sliding window heater module is mounted directly to the rear window. It is well known that when this module is exposed to moisture from the leak, it can cause the rear window to shatter or explode. The dealership has acknowledged this risk. A rear window shattering while occupants are in the vehicle could result in serious injury. When covered under bumper-to-bumper warranty, the dealership’s only solution is a “reseal” of the rear window. This is not a permanent repair, and many owners report repeated failures after resealing. This issue is easily verified through widespread consumer complaints. These trucks are expensive vehicles, and owners should not be forced to accept temporary fixes for a defect that presents clear health and safety risks. I respectfully request that NHTSA investigate this issue and take appropriate action.
