Alternator OEM Volvo or OEM Nissan

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

The 2.4 in my 2006 S40 was stone cold reliable to 157k miles before I sold it. Needed a new alternator at about 145k but that was it. It\u2019s been 2 years and I still miss driving that car. The BEST front seats of any vehicle I\u2019ve driven or ridden in.

My old 04 Volvo Xc90 had 311k on the dash before the alternator gave up lol. Doing better than that!

I replaced mine with a Nissan Quest alternator works pretty well and is cheaper with a higher current output there is a write up in the forums for it

Those alternators are damn near bulletproof, it’s the voltage regulators that crap out. If it were me, I’d keep the OEM unit, replace the pulley, and swap out the voltage regulator while I was at it.

I went and purchased an OEM alternator from Nissan and it is still not providing power. I have triple checked all the connections on the alternator, and have verified they are running 12V when the engine is shut off.

I ended up replacing the alternator but it wasn\u2019t a genuine Nissan part and it didn\u2019t work.

So I go to get some iced coffee because Dunkin just came out with pumpkin and the car doesn't start. Sputters. So I call roadside assistance for a jump. They tell me it can't be jumped and it's probably my starter. Real kicker is I then call for a tow, tow guy shows up and jumps it???? So I HESITANTLY drive it to the dealer who determines it's a bad alternator.
