Thought my battery (only 7 months old, in my 2002 Santa Fe) was faulty. Looks like there is an electrical issue. I had a problem with locking the car (kept unlocking). Now the battery is drained in 2 days of little driving. The radio kept turning on spontaneously and the windows wouldnt respond to go down the first try. It seems like there is something upsetting the entire electrical system. Got any answers??? I need to direct a 'local' to the problem rather than pay a heap for them to look and look and look!
