Alternator OEM KIA or Motorcraft

I had to order a motorcraft alternator which hasn't given me any problems 6 months later.

2011 Kia soul. 190k miles. No engine oil issues. Use fully synthetic that lasts about 10,000 miles per oil change. The only thing that I replaced twice was the alternator. lol

As far as replacements I've had good luck with Rock Auto Sticking to the better brands like Motorcraft, AC Delco, Remy, and Bosch.

The OEM motorcraft alternator in my focus lasted 14 years and its replacement, a Remy, lasted 6. If the difference in price between OEM and aftermarket isn't too big, and you plan on keeping the car for more than 5 more yrs, I'd go with the OEM.

I Had a 200k mile 2011 Soul and didn't have any major issues. 3k mile oil change, 3-5 yr battery change, some tire change, alternator replaced at 190k.

RockAuto does offer Motorcraft alternators and back in 2021, I purchased one for my 2016 5.0 Lariat.

Been there with a Motorcraft alt. 181K miles. She stopped charging. No batter light on the dash. I laid it to rest and paid my respects.

Go with an OEM unit by Motorcraft even if it's more expensive. Not somethin you want to do twice, learned this lesson with my Explorer. Threw on an aftermarket unit and it doesn't communicate with Ford's smart charging system correctly so it doesn't provide correct voltages as needed, therefore throwing a charging system warning constantly.

Garage told me the next day I need a new alternator.

It's a dice roll. I've had some success with them, but when I put a reman one in my Focus, it only lasted 2 weeks.
