The coolant will crystallize over time, Dexcool has just a 5 year lifespan. The thermostat will fail because of that . In my experience it’s the simple things that cause problems most of the time.
It’s just my opinion from 60 years experience working in cars , the beauty is that you can take it or leave it, but bear in mind we’ve been diagnoseing HHR issues since 2015.

The temperature movement tells me the ECT sensor is not in good working order. It tells the ECM information and that can tell the engine not to start.
