2015 AUDI Q7 Electrical System Problems

STARTED EXPERIENCING ELECTRICAL PROBLEMS WITH MY CAR. DISCOVERED ABOUT 6 INCHES OF STANDING WATER IN MY SPARE TIRE COMPARTMENT, ALSO WHERE MOST ELECTRICAL IS HOUSED. WATER FROM RAIN STORMS HAD SOMEHOW LEAKED INTO THIS COMPARTMENT. WAS TOLD IT WAS FROM SUNROOF DRAIN TUBES NOT WORKING PROPERLY.

2 YEARS AGO, WHEN MY BABY WAS 2, MY CAR LOCKED ITSELF BEFORE I WENT TO THE FRONT TO START DRIVING (THE CAR WAS PARKED). AUDIS HAVE A FEATURE THAT KNOWS WHEN THE KEY IS INSIDE AND DOES NOT TO LOCK ITSELF. THIS FEATURE WORKS 99% OF THE TIME, BUT FOR ME, OUT OF THE 3 TIMES THAT IT FAILED IN THE 2 YEARS I'VE HAD IT, 2 TIMES THE CAR LOCKED MY BABIES INSIDE THE HOT CAR AUTOMATICALLY. THE SECOND TIME HAPPENED A FEW DAYS AGO WITH MY 1 1/2 YEAR OLD, LIKE LAST TIME, AT NOON WHEN THE CAR WAS OFF AND 100 DEGREES OUTSIDE. TWICE 911 HAD TO BE CALLED TO GET THEM OUT.THE FIRST TIME THEY RAN A DIAGNOSTIC AND THEY SAID EVERYTHING SEEMED FINE. I FIGURED IT WAS A GLITCH. THIS TIME THEY WANT TO OFFER ME ANOTHER CAR, BUT I HAVE TO PAY MORE...
