Thermostat OEM Mazda or Duralast
I got a duralast part from autozone with a lifetime warranty for 25 bucks. My jeep has been been running well for the last year since the change to the duralast part
Pros: running well, lifetime warranty

Always buy the Mazda OEM branded thermostat from any local or online Mazda factory parts retailer, this is not the item you want to save a couple bucks on, no matter how much you trust that ‘other’ brand.
Pros: reliable, quality
Vehicle:
Mazda
Make sure you use a Mazda OEM thermostat. I wouldn’t trust anything but OEM for those.
Pros: reliable, trustworthy
Cons: non-OEM not trusted
Vehicle:

I will say I went through several OEM stats and finally put a duralast in and it's been in now 5 years no problems.
Pros: no problems, 5 years reliability
Vehicle:

Buy an OEM thermostat from Mazda. The aftermarket ones are sometimes not identical.
Pros: OEM quality, identical fit

I use duralast on my last 3 vehicles no problem.
Pros: no problem
They kept it for another day and were obviously able to replicate the fault and replaced the Thermostat as they thought it was sticking causing the Temps to fluctuate.
Pros: Thermostat replaced
Cons: sticking, causing fluctuation
Vehicle:
Mazda
Mileage: 89000 km
Thermostat failed multiple times
Cons: failed multiple times

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
Vehicle:
Kia Sorento
I just had the code P0126 on my 2021 mazda cx-30 with 20,000 miles. Seems to be the same issue
Cons: code P0126
Vehicle:
Mazda
Mileage: 20000 km
