I know the rule of thumb is if it’s running cool then it’s most likely that the thermostat needs to be replaced but this close to 210°F ?

Core Power Plays

The specs and strengths that make it shine.
Discussion on normal operating temperature for thermostats
I know the rule of thumb is if it’s running cool then it’s most likely that the thermostat needs to be replaced but this close to 210°F ?
Where is it supposed to be normally?
Update on thermostat housing replacement resolving codes
Update. They replaced this and all the codes cleared so I think there was an electrical fault.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Discussion on thermostat replacement costs varies widely
Looking online, I'm seeing less than $1000 pretty universally.
Discussion of filing complaints due to parts unavailability
I got a direct call from GM today apologizing, saying they will try to expedite the part and will see what happens.
My truck has been in the shop for 3 weeks now.
It takes a few days for them to review it and get in touch with GM but once you hear from GM, the part should be coming pretty quick.
Discussion about emissions warranty coverage
The dealership isn't answering that questions and I'm not sure why.
The emissions warranty covers specific high cost parts, not every emissions related component.
Thanks. [This is the warranty](https://www.chevrolet.com/bypass/pcf/gma-content-api/resources/sites/GMA/content/staging/MANUALS/3000/MA3212/en_US/6.0/2k17chevywm2ndPrint.pdf) and it looks like covers "Engine Coolant Temperature Sensor" on page 25 under emissions.
More likely it just needs to be removed to access covered items that do need replacing.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Discussion on the reliability of the Chevy Cruze
The Chevy Cruze, particularly the first-generation model I own, often receives a lot of criticism.
This car is accessible for anyone willing to learn basic mechanical skills.
For many, the maintenance history I’ve described might seem daunting.
Common issues with coolant leaks and thermostat housing in various models
Yes very very common prob. Replace the whole housing sensors and all.
Yes because it may be leaking when it gets up to temperature If it's cold where you are now it may not be doing it.
As others have said, it could be the head gasket/head leaking. It could also be an external coolant leak, or simply air left in the system.
Discussion on the reliability of the Chevy Trax
Buying a Chevy Trax was the worst decision I have ever made.
Mention of common criticisms regarding plastic components in cooling systems
some of those plastic thermostat housings will break and crumble if you just look at them too hard.
Common problem with 2019 Acadia thermoregulation
Sounds like it's a common problem with these cars, and the thermostat and/or temp sensor needs replaced.
Discussion on the meaning of P0128 code
P0128 doesn't mean "thermostat stuck open", it means "engine took longer to reach a preset temperature than anticipated"
Possibility of thermostat getting stuck again
The risk it can stick close again and overheat the engine.
Discussion on diagnosing temperature issues with coolant temperature sensor
My temperature gauge isn't moving an inch. My ac won't work due to their error.
More likely than not, the problem is a failed coolant temperature sensor that sits right behind the thermostat.
Various steps to troubleshoot engine temperature problems
Step 1 check coolant
Concerns about electrical issues affecting engine temperature readings
see if they'll do a warranty replacement to make sure it's not the sensor.
