Read about the recall, had dealer swap thermostat. Had a reason to leave right away with outside temp at 38 F. Warm air by the stop sign.
Pros: warm air
Vehicle:
Mazda
I had the same issue, in the end, the thermostat was faulty, and the dealership replaced it for free. I didn’t have any warning light on the dashboard either.
Pros: replaced for free
Cons: thermostat was faulty
I’ve had so many replacements fail in all my Nissans over the years that I just get an oem one from a dealer. Never had an oem one shit out yet.
Pros: OEM reliable, no failures
Vehicle:
Nissan
I had the same issue on my 09 Mazda 2.3L. Everything looked good on the dash, but the thermostat let too much coolant through, over cooling the engine. My CEL came on, I reset it, and it reappeared. Long drives on the freeway in cool weather was the scenario that triggered it, as the radiator is very effective at speed, and the engine isn't working hard cruising on level ground at freeway speeds. I bought the thermostat "cover" (it's the plastic assembly with the thermostat integrated in it-- PN LF70-15-170) for $57 from Amazon and installed it last November and the CEL has not reappeared.
Pros: CEL disappeared, engine cooling fixed
Part number: LF70-15-170
Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.
Pros: stable temperature, handles heavy loads

Nissan
Only an OEM Thermostat fixed it.
Pros: fixed issue

My 2021 Mazda3 Turbo has classic thermostat failure symptoms: \n\n- Erratic warm-up (sometimes stuck cold, sometimes near overheating). \n- Upper radiator hose stays lukewarm even after 20+ mins of driving (revved to 3K RPM to test). \n- Housing burns hot, but hose never gets scalding\u2014clear sign of a stuck thermostat.
Pros: erratic warm-up, stuck thermostat
Cons: sometimes near overheating

That's due to their faulty thermostat for which they don't want to assume responsibility and call it what it is - a recall.
Cons: faulty thermostat
I recently changed my thermostat due to my temp gauge occasionally dancing. The old thermostat appears to be bypassed as theres no actual thermostat in the housing. After putting on a new nissan one and oem gasket i bled the system with a overflow funnel for about 40 minutes until i stopped seeing bubble. Also using peak 50/50. Afterwards my overheating problem has gotten worse i overheat in about 10 minutes. I tried bleeding again and same results.
Cons: overheating problem worse

Nissan
Our 2022 CX-5 Premium Plus (non turbo) is going in for its 3rd thermostat replacement next week. Each time it’s been replaced at Mazda under warranty with an OEM part. Vehicle will hit 90,000 Miles this month. Does this thermostat wear seem excessive or is it normal for these? Bought brand new and it’s been the only problem, other then general maintenance
Cons: repeated failures, excessive wear
