CRAZY
 

Here's the story. 2005 cl55amg Bought the car in April .89 thousand miles. Has 92 know. Two days ago while driving all electricity cut out . Gear stuck n 1st . Antifreeze fluid leaks out. Message was charge battery. I let the car sit while battery charges and put some anitfreeze fluid In tank. Start car in driveway no antifreeze leaking .Message still saying charge battery. Take it out on road For about 15mn hit acceleration no problem no fluid leaking. Panal goes blk then pops on then off then on again.. Know message battery voltage to high . Later that night I move the car litterly 30 ft antifreeze starts leaking again slightly loosened cap leaking stopped..All I can say is HELP.

Water pump seizing or alternator problem.

Seems like you have two different issues . You could have a bad alternator either under charging or over charging causing these weird issues. If you have the tools put a voltmeter on the battery and see what it's doing .
