i have had this car for 6 months but i don't use the car during the week but when i go and use it for the weekend the battery is completely dead and i have to jump start it ,i thought it maybe the climate control ,but it cant be that because i noticed the fuse was missing and that was for the climate control ,ive disconnected the radio ,but still the same problem ,could it be the alarm .

 

bring it to vatozone for them to check the charging system for free to rule out the alternator and battery. if those check out you will have to perform a draw test to see what is causing the battery drain from sitting

 

As the other post said, get the battery and alternator tested. I had this happen with dodge, the battery was not holding a charge, but if driven every day would start. You will need to look up vampire drains. You can look up how to put a multimeter on a disconnected battery and see how much power is being drawn. Note you may have to wait 30 min after stopping the car to make sure all electronics are shut down.
You can then have a friend pull a fuse one at time, see if voltage drops. If not replace and try another. That at least may tell you where the problem is.
Check simple things like vanity lights and trunk light are turning off.
