Alternator OEM FORD or OEM Nissan

OEM. I've had to warranty and eat so much labor from faulty auto parts store starters and alternators it's unreal. They cost more, but I rarely have an issue with OEM.

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.

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.

My car started experiencing the same issue as yours. Randomly lose power, no acceleration, give jump start, two days later, the same issue. Had to have it towed to Nissan. Yes, long story short, it does need a genuine OEM Alternator and OEM Battery! For some reason, the 3rd party parts are not as effective in the product. Once placed in my Nissan, it was commented there have been no issues.

My 2005 Altima used to eat alternators. The first and second replacement were rebuilds or aftermarket, I don't remember the order. I finally paid for an OEM and that one lasted until I sold the vehicle a few years later. This is one of those parts that is better to stick with OEM replacements.

Nissan offered me around the same price for my 370z alternator replacement. I went to eBay and bout a used oem alternator from a rear ended total z with 3k miles on it for 80 bucks and changed it myself

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

I have a shitty looking Ford Focus that I maintain myself...The alternator failed and I couldn't be bothered doing the work myself so I took it to the local dealer.

I haven't had this problem with my RX8, but I had a similar problem with my Ford. Alternator was putting out 14.4V, but I still had a light. Took it to the parts store and they hooked it up to their tester. It said the Alternator was no good.

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.
