Rod Bearing TLX v6 SH-AWD

Engine started knocking before new years, lost ability to accelerate more then like 2.5k rpm. Let it sit in driveway while waiting for dealership to open again, took to dealer and basically told “goodluck” I have to drive a car that can go maximum 70 mph (while shaking badly) and shakes at idle. Their recommendation was “don’t drive as much” or “go on any long trips” Am I crazy for thinking that a loaner would be nice? I told them write a letter saying it was safe to drive, refusal. This is just unacceptable in my opinion.
