If the alternator is OEM, replace it, because is close to the exhaust manifold, it will fail sooner than later.
Pros: engineered through
Cons: weakness for heat

After getting mine rebuilt 3 times and still having the same problem, I ended up getting a Bosch factory rebuilt one. Cost-wise I don’t think it was significantly more than one rebuilt by a shonky auto electrician and in the long run would have been cheaper.
Pros: cheaper in the long run
Cons: rebuilt multiple times
Had the same issue a few months back. Put in a new alternator and it’s been perfect since.
Pros: perfect since

check the charging at the battery while the car is running about 2000 or 2200 rpm with multimeter. The alternator should be charging at 14 volts (give or take a little)
Pros: charging at 14 volts
Cons: false readings at idle
Vehicle:
Volkswagen Jetta
Mine was my alternator. Never had battery issues but once I replaced it with a new bosch all the electrical gremlins the car had went away.
Pros: electrical gremlins went away
I just replaced the one from my 1996 Passat Tdi. 326k miles on it. The alternator still works too!
Pros: alternator still works
Vehicle:
Volkswagen Passat
Mileage: 326000 km
My v6 03 avalon xls alternator replacement, parts and all was under $300
Vehicle:
Toyota Avalon
Mine has 69K miles. I've owned it for 4 years. Replaced the alternator and MAF sensor after failures. Keyless entry works only sporadically on the driver's door (lock switch already replaced - latch mechanism needs to be replaced, but for $$$).
Cons: alternator, MAF sensor failures

Mileage: 111042 km
ended up going with a Bosch remanufactured alternator. Installed it today, went super smooth, charged up the battery as I was installing it, got everything buttoned up and started it up. Battery light still on, voltage is at around 11.9 and dropping. Will randomly jump up to 14.4 volts, no correlation with revving the engine or putting a load on the electrical system.
Pros: smooth install
Cons: battery light still on
Vehicle:
Nissan Murano
RX is garbage, use the lucas one
Cons: RX is garbage
