2019 Regal Tourx
I have changed the engine in my car. The old one blew at 200,000 miles. The replacement engine has 70,000 miles on it. I went to fire it up for the first time and 28 codes have popped up and no power steering. Has anyone else gone through this?
 
I'm curious what caused the catastrophic failure @ 200k?

What are the codes?
