Alternator OEM FORD or OEM KIA
I had lots of issues with a ‘96 4.6 Cobra. Back and forth between battery, alternator issues. Maybe, six months between issues. Finally replaced the alternator with new, not reman and changed the battery at the same time. That lasted for the next three years that I owned the car and was still fine when I sold the car.
Pros: new alternator lasted
Cons: alternator issues
Vehicle:
Ford
I had a similar problem with my 08 mustang GT. The alternator burnt through the cord going from it to the battery. Bought a remanufactured alternator and replaced it. Still didn't work. Traded it in for another remanufactured. Still didn't work. Finally returned that one and bought a brand new one. Works fine 6 years later and no problems.
Pros: new unit works fine
Cons: reman units didn't work
Vehicle:
Ford Mustang
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.
Pros: bought used alternator
Cons: alternator failed
Vehicle:
Kia
Mileage: 32187 km
I have experienced my share of faulty Ford alternators from the chain stores. I now get OEM from Ford. Yes, they are expensive but I have better things to do than replace month old alternators constantly.
Pros: better than chain store alternators
Cons: expensive
Did they put in an OEM ford alternator? Fords switched to their “smart charging” system and its a little more complicated than your average alternator diagnosis.

Newer ford alternators essentially “talk” to the pcm. Cheap aftermarket alternators do not do well on these cars. Replace the alternator with a better quality alternator
Pros: better quality alternator
Cons: cheap aftermarket alternators
Vehicle:
Ford
Had issues with every single Ford alt I replaced (from autozone, Napa, Oriellys) didn’t matter. Only had luck with either dealer parts or from a local rebuilder.
Pros: dealer parts worked
Cons: aftermarket parts failed
I once went through 3 alternators in 2 days from the Ford dealer on one job.
Cons: multiple alternators failed
Vehicle:
Ford
Go with a new OEM. I had a Ford E250 I put a remanufactured one in and it lasted like 2000 miles and gave out.
Cons: lasted only 2000 miles
Vehicle:
Ford
Mileage: 3218 km
I had one during college... For a V6 it wasn't particularly quick and handled a lot bigger than it was. In three years it ate five alternators and the intake runner control box was notorious for failing (killing what little power it had).
Pros: sounded good with exhaust
Cons: ate five alternators
