What's wrong?
The fuel tank shell on 2021 Chevrolet Tahoe and Yukon vehicles is the outer body of the gasoline tank. It holds fuel under the vehicle and keeps liquid fuel and fuel vapors contained as the tank expands, contracts, and moves with normal driving. Adhesive between shell layers helps those layers stay bonded and sealed.
On the recalled vehicles, the supplier missed adhesive during a short production window. Without that bond between the tank shell layers, the fuel tank assembly can separate enough to leak gasoline. Replacement tanks were built outside the suspect production window, so the dealer repair uses a tank shell that has the proper adhesive bond.
Owners can notice a fuel odor near the vehicle. Treat that smell as the warning sign, especially after parking or after a drive, because it indicates fuel or vapor is escaping from the tank area.

What happens at the repair
At the dealer, a Chevrolet technician replaces the fuel tank assembly covered by recall 21V064. Parts and labor are free under the recall. The replacement addresses fuel tanks that are missing adhesive between layers of the tank shell, a condition tied to fuel leakage in the filing. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because all covered vehicles are under warranty. Ask the service desk how warranty coverage applies to prior repair paperwork.
