I've owned my 2006 Azera Limited for two months, but it's mostly been at the dealership for a mysterious electrical problem. If the car sits for more than 5-6 days, the battery is as dead as can be. The dealership found no problems and finally replaced the battery. After 8 days of non-use, everything's dead again. The Hyundai mechanics are at a total loss as everything tests okay. They are asking corporate for an "expert" to help out. I don't even have over 200 miles on this car. Does anyone have any ideas? I've suggested a faulty alternator diode or computer, but testing shows everything positively in acceptable condition. Do I have a lemon? Any suggestions?
