Need Advice - 2018 Yukon Denali - needs new engine

As a mechanic for many years, I had a customers car towed into my shop for a no start condition. I quickly tried cranking it over and could see almost no movement from the harmonic balancer. I told him it had probably seized but I would look into later when I had the time. It turns out the alternator was locked solid keeping the engine from turning. It's hard to believe how much torque a serpentine belt can hold without slipping! If they haven't taken a deep dive into it I wouldn't trust them. Another example of dealer dishonesty is when I took a part time job as a Napa driver after I retired and in my late seventies. The Dodge caravan I was driving started slipping in reverse and popping out of park. I told the store owner it was because the outer cable had come loose and instead was sliding out of the crimp keeping it from pushing the the shift lever on the trans but allowing it to pull it into the forward gears. The Napa owner sent it to the local Dodge dealer who told us the trans was shot AND it also needed a new engine! That's as bad as many dealers can get.
