If the engine is replaced,…
If the engine is replaced, it will probably be a reman. At 95k, my 2019 siverado had a warranty engine replacement. Not a new engine, a reman. The warranty was extended 100k or 3 years. I took a 2500 mile round trip after I got it back. Drove it like I stole it. So far so good. The issue was/is the DFM. I bought one the afm/ dfm delete modules and it seems to run better. Buying the module and using it was the advice of the service department Mgr. If it gives me a problem again, it's gone. BTW, the dealership had my truck for 9-10 weeks.
