Let sit for a few hours and take another voltage reading. If it reads below about 12.3V (~75% charged), then the battery has a problem, you have a drain somewhere, or you are not charging.
Thanks SouthArk370Z I will check the battery again. i didn't check the battery voltage before but it seems that the car is consuming power while its completely off, takes the power from the battery. I replaced it two times, Ill replace it again since the battery is under warranty.

Any more suggestions much appreciated.

Thanks to all!
