New 2020, 3500 6.7 Cummins with new 50 gallon fuel tank keeps triggering check engine light if fuel tank gets close to 1/4 empty. Not empty! NOT displaying a fuel light!! The check engine light is coming on!! Dealership is saying that ram has installed the tank without software for the tank do the truck is thinking the truck is EMPTY! Anyone else having this issue or know of ram having a fix? Seriously considering a lawsuit. Been to dealership more than 6 times for this and other stuff and just had first oil change.
