2023 GMC Sierra 1500 fuel system problems

The fuel in the tank is splashing around and makes bump sound when you come to a stop and is worse when the fuel take is full and goes away the lower the tank gets. GMC has a service bulletin out PIT5161J stating this is a normal condition. This is not normal, I have never had any vehicle I have owned have a fuel tank noise let alone have felt a bump that you can feel in the seat. There is obviously something manufactured wrong and needs to be addressed.
