When I drove home from work friday everything fine. When I went to start teh car today I just get clicking sound does not turn over. Radio and lights work. 2006 Sonata.

Is you check engine light on...have you check for trouble codes?

alternator bad??? causing a drained battery

check for a bad ground wire to your battery

BY WHAT YOU ARE SAYING IT SOUNDS LIKE YOU MIGHT HAVE A BELT ISSUE, WHAT I WOULD IS OPEN THE HOOD AND LOOK DOWN AND SEE IF THE BELT IS STILL THERE, IF IT IS GRAB IT AND PULL ON IT MAKE SURE IT ISN'T TO LOOSE. IF ALL IS GOOD THERE I WOULD GET THE ALTANATOR CHECKED OUT SOULD BE PUTTING OUT 14.6 VOLTS WHEN RUNNING. TRY THAT HOPE IT HELPS YOU.

You need to find the source of the leak. it hasn't overheated yet because you keep catching it and re-filling. From your description, it sounds a lot like a bad water pump seal (part of pump) but without physically looking you can't be sure of that. when the pump seal begins to fail, internal pressure while running often will drive the seal tighter against the shaft stopping the leak. as pressure drops as the engine cools, the seal relaxes and permits seepage.
With time, that will change and it will leak all the time.

The ignition relay is faulty.
Look into that.

Thanks!!

sounds like a starter

Have the charging system rechecked. It sound an AWFUL lot like an alternator not charging the battery to me.

Check battery terminals make sure they are not corroded and that the are tightly secured. If all is good the battery is at fault. Replace battery and then have charging system checked to make sure the alternator is working fine. Or you can remove the battery and have it load tested a t an Auto_zone for free.

chek the alternator
