I bought a 2018 Chevy Express 3500 Cutaway brand new. It now has 37000 miles on it and the fuel pump needs replaced. It has been at the dealership for a month now waiting for them to find the part. They actually said they don't think they make the part. Been conversing with General Motors trying to get resolution and they say that they have it at top priority to find part and send to dealership. This box truck is our business, so we have been having to pay $150/day to rent a truck. Does anyone have any ideas as to what we can do? I'm up for any advice at this point
