some GM trucks have issues with heat soak on the starter where the starter actually doesnt work at all when the engine is hot. Let them cool off for a few hours and they fire right up again. Replacing the starter does nothing. Its an engine design flaw

Some GM engines would heat soak the starter when hot, making restarting harder on the starter motor. I believe the LS3 still had that problem, but it was worse in older V8 GM vehicles.
I'm a GM technician and these starters fail just as often as regular starters except they are 200% more expensive.
The starters on the V8 trucks are made of paper mache.
Mom had an Envoy XUV for 10 years, only issue in that period was the starter, gauge cluster stepper motor, and the divider window motor. I had a Trailblazer SS for four years, would still have it if I hadn't sold it to buy my house, but in that time I did front hubs, steering wheel position sensor and a pass side wheel speed sensor. That was it. ZERO other issues.
