Fuel pump assembly went out at 47k miles. It took three dealerships to finally find the part as it was on back order. No aftermarket company makes it so you have to buy OEM. It would have taken the dealership several weeks to fix it since they were behind on servicing other vehicles and also having trouble getting the part. I replaced the fuel pump myself since it is my daily and couldn't wait for dealership. I contacted Ram care about the issue and they opened up a case. They opened up a case but eventually denied reimbursement with no reason.
