2021 Mazda CX-30 Owner Comments
Mazda refuses to put decent batteries in their vehicle. Mechanic even said Mazda batteries are only made in mexico to cut costs, hence OEM batteries are weak and have battery drain problems.
My battery was gone in just 5 months of car being new. This is absolutely bull crap.

I went to start my CX-30 in the late morning of 1/18/2024 and well, it wouldn't. Seemed to have a dead battery. Got a jump start from AAA, their jump box said the car was charging so it appeared to be the battery.
From a fan site for this model, there seems to be 2 factors for this. One is a 'cheap' quality and capacity battery. The original is only 520 Cold Cranking Amps (CCA). Second is draining issues that can run down the battery, I guess for safety, convenience and a dash cam I have hooked up full time sucks up a lot of juice. The original battery was installed at the factory in August 2021, I had bought the car in September 2021.
As no longer under the 3 year/36,000 mile warranty (has 38,500) a replacement battery was on me. I replaced the battery with a much better NAPA one, with 650 CCA. Hopefully this will never be an issue again. My point is that an original battery should last 4-5 years, not even 2.5 years. It is an annoying issue, glad it happened at home and not in some isolated or hazardous place.
