Alternator OEM Mazda or Duralast

Our 17 has 205,000km so far. Has been great. Have gone through 4 sets of rear brakes, maybe 2 front but it might only be one, had to recently replace the alternator.

2004 Limited with 310000 miles alternator went out so went to local service shop . They were able to get it in and repaired next morning other shops in the area are a week backlog.Parts we're 310.00 (Duralast alt.and Gates belt)

I went with a Duralast Gold(90A) which never gave me a issue. If I had a oscilliscope im sure it had good output.

Possibly the alternator, mine did that so I bought a brand new duralast gold alternator and it solved so many of my problems.

I’ve had two D/L Alternators. Each has lasted 3 or 4 years.

I’ve never had an issue with a Duralast starter or alternator. However, honestly, I probably wouldn’t put one on my Lexus. I’ve generally shoved them into cheaper and simpler cars.

Mazda's DO NOT like aftermarket alternator. Most don't work out of the box. You need to get a genuine Mazda alternator.

Got a remanufactures duralast alternator. Worked for about a week and the died.

My 2017 Mazda 3 touring felt like it was cursed. I had the direct high pressure fuel pump injector go out like 1.5 years after purchase. About 2k for just that repair. Thought that was the end of it until the following year where there was a persistent evap problem that nobody could find, despite clearing the code it wouldn’t pass smog. One smoke test and several hundred dollars in appointments later they found the smallest leak from one of the hoses, replaced it and passed smog. Then the check engine light saga started, at first we thought it was the battery/alrernator until after replacing both it kept happening. Turns out that was the start of my catalytic going out(76k miles exactly). Idk if it’s Stockholm syndrome but i did trade it in for a new Mazda. Hoping the curse has been lifted.

Reman alternator quality is in the toilet. Not uncommon to have to warranty an alternator once or twice.
