I dropped my car off at the dealer this morning to check out a check engine light that self extinguished itself ... twice. The checked the code left behind and turns out it was due to low battery voltage so I need a new battery. I thought, "that's fine the car is still under warranty". Not so fast there buddy, seems that batteries are only warranted for 2 years or 24,000 miles not 3 and 36,000 like the rest of the car. the car is 30 months old with 22,000 miles on it. They'll put one in if I give them $275 but I'm sure I'll pass on that. I coulda swore the battery was covered 3/36. Oh well. I'll check the warranty book when I go to pick it up just to be sure.
