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
Been running a duralast in mine for about a year no problems.
Pros: no problems

The only good thing about buying a duralast is it'll be the last alternator that you have to *PAY* for. But it def will *NOT* be the last alternator you install in the truck. Lol
Pros: last alternator you pay
Cons: frequent alternator install
Right on schedule, about 7 months later, that reman also went out and I decided to pay more to get the Duralast Gold which is all new. That one lasted about a year and a half but then the bearings went out on it, but I don't think that issue was the alternator's fault because after I replaced it, I found out the Harmonic Balancer had lost its integrity and was wobbling a little. Again, not sure what caused what (did the bearings put extra pressure on the aging balancer or did the balancer go out and damage the alternator?), but all I can say is that since replacing the harmonic balancer and using the Duralast Gold alternator, I have not had any issues for over 2 years now.
Pros: lasted a year and a half
Cons: bearings went out
Vehicle:
Toyota
I bought a Duralast for my ‘99 E55 a few years ago. It didn’t work so I pulled the rectifier off of it, put it on the original one, which put out at 14.2 v back in the car. I returned the Duralast one after I made the old rectifier look like new. The shaft rotation on the Duralast felt gritty, too.
Cons: didn’t work, shaft rotation gritty
Duralast = Duramightlast. They're just overpriced cheap rebuilt cores.
Cons: overpriced, cheap rebuilt cores
All I could recommend is stop buying the autozone/duralast alternators. Buy a good brand, ie Denso, Delco, Motorcraft, etc. and return the duralast one outright for cash in hand.
Pros: return for cash
Cons: prone to premature failure
Duralast..... if you want to get really good at changing them.
Cons: changing them
