I had the same issue and throwing a bad thermostat error code. I had the thermostat replaced and it kept happening. He said the thermostats out there are crap and they’ve had to change some 3 times. He did recommend getting a Mopar thermostat if I could. It was replaced and I’ve had no issues.

Pros: no issues
Cons: kept happening, thermostats are crap

The OE version is the only one that works. Knock off t-stats will generally last a few weeks to a few months. The OE thermostat has been updated, pops at 203 degrees and lasts much longer than anything else. An OE thermostat seems to fail open. Whereas the knock-offs fail shut.

Pros: lasts much longer, fails open
Cons: last a few weeks, fail shut

I warranty my shitty duralast thermostat (I hate duralast but when I gotta get to work the next day it works in a pinch it works) now after a 5 am swap I’m good to go

Pros: works in a pinch
Cons: shitty quality

I’ve changed mine once already recently (it was a duralast thermostat because I’m stupid, that might be the current issue) and it’s still acting similar and trending towards overheating at 60+ mph even with the radiator fans on high. The radiator in lines are frigid after it’s been running at mid/high temps and the radiator out lines are hot

Cons: trending towards overheating, acting similar

I'd advise taking that Duralast thermostat out and installing either an OEM unit or a unit from a trusted brand (such as Stant). If the Duralast gets stuck in a closed position, the SUV will overheat. If it gets stuck in an open position, the engine won't reach operating temp, and you'll have issues such as running rich. Duralast has a nickname we techs refer to: Duracrap or Dura-doesn't-last.

Cons: gets stuck, engine overheating, poor reliability
