I had the same thing happen with my 2006 Tucson -- after replacing the battery I would again have problems starting the car or the battery would just die -- eventually I was told it was the radio draining the battery even when the car and radio were off!!! The dealer replaced my stereo system with a new one and I have been fine since! Hope this helps ;)
