Fords can be really picky about which alternator you use! Even if it’s a remanufactured Motorcraft, it’s worth it. Had a friend with an 11 Edge 3.5 that we put a aftermarket alternator in and it complained errors etc… for months till we finally swapped it out and it worked fine with the Ford part!

Pros: worked fine, worth it
Vehicle: Ford Edge

I just replaced mine with a motorcraft one from rock auto. Yeah it's pricier than reman or other brands but if it lasted 20 years and 190k, I figured that this would last just as long. Get what you pay for

Pros: expected longevity, good quality
Cons: higher price

Mileage: 190000 km

I also noticed that the alternator looks like a remanufactured unit. I’ve been reading about how these PCMs really don’t like reman units that are not built perfectly to spec. It’s best practice to replace these with only motorcraft units.

Cons: PCMs don’t like reman units

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

Pros: genuine Mazda alternator needed
Cons: aftermarket alternator bad

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.

Pros: passed smog after repair
Cons: fuel pump injector failure, evap problem, check engine light, catalytic converter failure
