Okay i have a dumb car question....in late February I found out that my car needed to have the (short block) engine replaced on my car which is only 3 1/2 years old. They took the top part of the engine off so they could send pics to Hyundai to make sure it was covered by the Hyundai 100,000 mile warranty (which, thank God, it was.) So the car hasn't been started since late February. They got the engine in yesterday and put it in yesterday. However, they emailed me and said that the battery no longer holds a charge and said it was cost $360! to replace the battery. Should it be my responsibility to replace the battery or should it be theirs since i didn't have a problem with it before and they never started the car since late February? Also, this originally started in February with an oil change and in the list of items they checked, the battery was one that was checked as being ok.
