A friend of mine had the alternator on her 2003 Hyundai Santa Fe go out last week. For some unknown reason she had the vehicle towed to the local Chevy dealership to have it fixed. She did however buy the part at Advance instead of using the GM part. She told me today they charged around $210 labor. Having replaced a few alternators that sounds extremely high to me. Even if you give them an hour's labor as a diagnostic fee it should take a trained mechanic less than twenty minutes to replace the part. I can't imagine "book time" could be more than an hour. Can any mechanics give me an idea of how much time the guidebook gives to replace this? Also, I told her if she ever has a problem like this again to call me and I'll fix it for nothing instead of her getting killed like this.
