Alternator OEM KIA or OEM Mazda

The alternator on my 2019 Forte failed.

I bought a used one with 20k miles on it, an new idler and tensioner pulley for around $350. Installed it all myself.

Got some faulty alternators from autozone that were overcharging or undercharging. I just bought an oem reman from mazdaswag, (or any mazda dealership store online). Works fine now.

Garage told me the next day I need a new alternator.

I'm surprised Mazda is rated so poorly, I had a Mazda MPV for 8 years and honestly the only problem I had was the driver's side window gear was worn out, and the alternator.

I would suggest the genuine Kia one, or a professional grade like NAPA's top line or an AC-Delco. I would avoid anything that says "USA Industries" or "Duralast" on it, based on personal experience. In our shop we have had nearly 100% failure rates with those brands.
