I have an 06 Santa Fe which I bought new. About a year and a half ago we started experiencing battery drain when the vehicle was parked 2-3 days. We replaced the battery and the Hyundai Dealer has looked at it 4 times. They say all is normal. I have to carry a jump start pack everytime I leave town now. It seemed that it was in the alarm system but am not sure now. Any ideas out there? Yes, we have checked all the lights doors, radios..

 

OK, do a parasitic draw test and see what you working with...

Could be bum battery too... been there, done that..
