Rating 4.0

I had the same exact car with same exact problem. I changed the thermostat once and it fixed it for about a year. The issue came back and I changed again and it fixed it again... So I'd say get an OEM one if you can.

Pros: fixed it for a year
Cons: issue came back
Vehicle: Honda Civic

OEM Mazda Thermostat

Some of the newer Mazda Skyactives have thermostat issues, but it's a minor problem (only symptom is taking longer to warm up) and Mazda extended the warranty on them. It's the only issue I've brought the car to the dealer for on my 21 Mazda 3 without roughly 50k on it.

Pros: minor problem, extended warranty
Cons: thermostat issues
Vehicle: Mazda
Mileage: 50000 km

Rating 3.0

I have the ‘19 CX-5, live in NH. Seems normal to me, when it’s below zero outside and the at idle, it should not be hot. Warm after 5-10 yes, but not warm as it would be after driving for 10 minutes.

Pros: Warm after 5-10
Cons: not hot at idle

Common for the thermostat and/or coolant control valve to fail on newer Mazda 3s. It's not a big deal but you might have more coolant loss and it takes longer to warm up.

Pros: not a big deal
Cons: coolant loss, longer warm
Vehicle: Mazda 3

I just got this fixed at the dealer on my 21. Its the thermostat. They put in over a million bad ones and don't want to own it with a recall so they sent out a TSB. There's also an extended warranty for all the cars for this part/labor.

Pros: fixed at dealer, extended warranty
Cons: defective part, no recall
