What's wrong?
The fuel tank on the 2019 Mercedes-Benz G 550 is the sealed container that stores gasoline under the vehicle. It also helps manage fuel vapors and keeps fuel contained as the engine draws from the tank.
NHTSA campaign 21V564 concerns tanks that were not welded properly during manufacturing. Mercedes-Benz traced the issue to a supplier production deviation, which means the tank did not match current production specifications. If the weld area opens, fuel leaks from the tank instead of staying sealed inside it.
Owners can notice the smell of fuel or a flashing check engine light in the instrument cluster. Those signs mean the fuel system needs dealer attention, because the tank is no longer doing its basic job: holding gasoline safely.

What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the fuel tank covered by the recall. The replacement parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, since the involved vehicles remain under warranty.
