I'd say to change out the coolant, and transmission fluid. DO NOT GET A TRANSMISSION FLUSH!!! Just get a place to change out the transmission filter, and top off the transmission fluid.
Cons: DO NOT FLUSH
Vehicle:
Mazda 6
Yes I had low coolant in my brand new CX-30 and had to top it off 2-3 times with the FL22 fluid (factory OEM). I think some air is left in the system that gets out over time. Since then no issue with the coolant level
Pros: no issue since
Cons: low coolant initially
Vehicle:
Mazda
Mileage: 94000 km
Part number: FL 22
I had my AC condenser replaced and looked at it in the parking lot and confirmed it was full of coolant, drove home, and it was low. I ordered and added some OEM coolant at home. It's been fine ever since
Pros: fine ever since
Cons: coolant was low

Mileage: 57900 km
This is normal. Mazda master tech. I work on these everyday. Every oil change they need to be topped off. The coolant evaporates from the bottle pretty quick.
Pros: coolant evaporates quickly
Vehicle:
Mazda 3
You're not supposed to add tap water... distilled water is fine for emergencies, but always top up with coolant whenever possible
Pros: distilled water for emergencies
Cons: not tap water

My 2017 CX-9 and it has a coolant leak from the back of the block by the manifold and the shop I took it to said to take it to a dealer.
Cons: coolant leak

I recently changed the coolant in my 2020 CX-5 with genuine Mazda prediluted FL22. The reason I change the coolant is corrosion protection. The corrosion inhibitors in coolant deplete with both time and mileage. Many aftermarket coolants may not be formulated with the identical corrosion protection chemical strategy found in the Mazda FL22 coolant. Using an aftermarket coolant is a risk I am not willing to take. My cooling system remains safe from corrosion. Using my schedule I will not have coolant and internal corrosion issues for as long as I own my car. Peace of mind is worth it to me.
Pros: corrosion protection, peace of mind

I noticed a coolant leak the other week and bang - this was the exact issue.
Cons: coolant leak
Vehicle:

Mileage: 135000 km
Last time I priced FL 22 at the Mazda dealer it was about the same as AutoZone I was surprised I thought it would be considerably more.
Pros: same price as AutoZone
Part number: FL 22
