This is the third alternator that I have replaced in the last 100k miles I have driven the car. It's about 4 or 5 hours to remove and replace and requires removing a tire, the wheel well and unmounting the AC pump to drop the alternator out the bottom.

I had one alternator go on me and the dealer had replaced it free of charge. The rebuilt alternator went bad on me a few months later. I replaced that one myself with a new alternator I got online. To change out the alternator you have to disconnect a pulley and detach the A/C pump so that it will fit out of the bottom. Also for ease of repair you have to remove the front passenger tire and wheel well guard. About a 4 or 5 hour project.
