And assuming that the alternator is the issue, hope you get an oem good part or a used one, on nissan altimas/maxima Remans are bad.
I did one on my Wife's 2011 Nissan Quest with the same engine as the Pathfinder.
Original one lasted around 130k miles, so can't really complain.
The one on the Quest wasn't great, but I think I got it done in about 4-5 hours.
Had to pull the lower bumper splash shield, and the passenger fender liner.
Then I unbolted the ac compressor and let it drop down (was able to leave all the refrigerant hoses connected so that was a plus).
The upper bolt was a pain to get to, probably the worst part of the job!
With it unbolted there was just barely room to get it out through the wheel well. If you had it positioned just right it would slip through the opening between the subframe and the frame rail.
Nissan use to be good
The alternator quit on my 2020 Nissan Sentra, and there were NO aftermarket options for it. The dealership wanted $900, JUST for the alternator, so I can actually believe their price.
Had one do this on me and it was the alternator.
I've gone through 3 Nissan Value Advantage Alternators (through the Infiniti dealership - warranty) for my Q. All Infiniti offers for my year (2015) are Remanufactured Alternators. I'm tired of Remans.
I bought a remanufactured alternator from Autozone and it did not work. I then bought an amazon alternator. It went out 2 weeks later. I then bought the OEM Nissan alternator. I've not had a problem since (6 months)
The voltage regulator on the alternator is bad.
November of 2023 I had to replace the alternator. I purchased an aftermarket and had a mechanic friend install it for me. 6 weeks later it started acting up again and left me stranded. The battery tested good, alternator was bad. I returned the alternator and was warranted a second one. Roughly 2 months later, the battery light comes on while I am out of town. I pulled into a local parts store and had it tested. Battery tested fine. Alternator tested bad. The Nissan dealership says it is the alternator. But since I had not used a factory alternator that was the problem. Apparently the aftermarket alternators can not handle the load and are not set up properly.
Z1 Offroad has an OEM Nissan remanufactured for a good price, that's I what I went with.
