SOURCE: radiator leak
if you want to make sure you can put some soap bubles on the hose and see where the leak has actually taken place as a first step in diagnostic.
just pour the soap on the top and you can see (not inside the radiator), once it blows then there is your leakage.
either the radiator itself is the prob or the hose

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

The central locking system is controlled by the ecu, simply a common fault, disconnect the passenger door terminal to the lock and see what happens if the other doors lock normally then this confirms that there could be a fault in the wiring loom or relay if the doors unlock after locking then its a ecu problem. See an auto electrician
Regarding the water consunption what colour is the oil hope its not cream, radiator cap may need replacing as it could be blowing the water out, if the reseviour bottle is always full then this confirms it..Hope this helps you out

Could be the overflow canister or a seal in the front of the engine. Have the system pressure tested to be sure of the origin.
