I bought a 2006 Elantra approximately a year ago with about 50,000\nclicks on it. The car performs great until recently. On 3 different\noccaisons at about a week apart I go to drive the car but it is\ncompletely dead. The keyless entry will not work...the clock is out\nand the door open ringing sound is gone . When I put the key in the\nignition absolutely nothing! Not even a clicking sound. It is a total\nloss of power. On all 3 occaisons I had my car jumpstarted and it\nfires up fine. Once the battery is charged the car runs great again\nuntil the next time this all happens again. Is it my battery? Is there\nsomething seriously wrong with my car? Any help would be much\nappreciated.
