Been here awhile...
Thanks for all the help.
I bought a new battery last night and installed (yeah I know make the dealer pay but it isn't worth hours of my time)...
this morning the battery reported 12.8 after sitting 10 hours. The oem never reported that high in the morning.
bad battery....
Hopefully you have time to draft a letter to Hyundai Corporate to let them know what you had to do with your battery. I would even try to include a copy of this thread you started. Maybe this might get you your money back for the battery. Make sure you attach a copy of the receipt.
