Alternator OEM Mazda or OEM BMW

Please, genuine alternators are only like $30 more and you won't suffer these issues. And also they last.

I went and got a Mazda one off of Moss bc I was sick of AutoZone remanned ones blowing up. It's plenty nice for stock electrical load

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.

Had the same issue a few months back. Put in a new alternator and it’s been perfect since.

You need to try using a OEM REMAN or OEM NEW alternator. Aftermarket items can really affect BSD.

Have been burned by aftermarket alternators. I'll spend the money for an OEM every time.

My 540i at 141k started eating me alive, Alternator blew up

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.
