Most of the time the issue is the alternator and not the battery. Since the light is on that indicates that the fuse is ok. I would run it either back to the dealer and have them replace the alternator, or head to a parts store and ask to have the charging system tested. If the alternator is producing less then 14.2 volts under load it needs to be replaced.
Under load means with the headlights, wipers and blower motor all on.

Then it would be a wiring issue from the alternator to the computer and instrument panel. 99% of the time however the issue is the alternator. Some of these do have issue with the instrument cluster, however when that's the problem, usually all of the gauges fail.
Is this the 6 cylinder or 4 cylinder engine?
Thanks, that's the 4 cylinder engine.
This one is fairly easy, the labor guide is only looking for an hours labor to replace it. It's bolted right to the front of the engine.
lol, no problem at all. This is really a fairly easy one to change. You will probably have more issues with the belt then the alternator. Might be best to go through the wheel well to get the belt off.

You would have to purchase a new belt, but that really depends on the condition of the old belt. If the belt has cracks in it, replace it. If not no worries.
You are very welcome!
It's a real good question. I personally haven't had much luck with aftermarket alternators.
You might do better with a used one to be honest. The aftermarket and remans sometimes only put out 13 volts. That just isn't enough.
You're very welcome.

I would still have it tested and contact the dealership. Let them foot the bill if possible.
