I don't know any shop that can diag, order and replace a motor before the 30 day out of service clock runs out and it becomes a lemon and that's before covid, now forget it. Then its WHOLE NEW TRUCK time.Will never happen. Manufacture isn’t gonna give every customer with a brand-new vehicle that needs an engine a new car. I’ve seen that before where I work and they tell customers to kick rocks. If the engines are available that’s what they’re gonna do is replace it and pretty much tell you to be on your way.
If you want to deal then sure, ask for a warranty forever and a new engine or whatever, but 99% of the time you are better of making them eat the truck under lemon law and getting a new truck.
