Filling this vehicle with diesel fuel per the manufacturer's user manual instructions results in a fuel leak centered between the rear wheels from somewhere at the top of the fuel tank. This has occurred during almost all fuel fill-up stops over the last year. The local dealer could not find the problem. A similar issue occurred with the 2021 diesel Yukon which has the same fuel tank as verified by part number. This was quietly remedied under warranty by the manufacturer.
