WATER LEAKING IN FRONT RIGHT FLOOR BOARD CAUSE SHORT IN ELECTRICAL SYSTEM, ALSO LEAKING IN REAR AT BATTERY AREA. DEALER HAS ADVISED THIS ALSO CAUSED THE SHORT IN THE ALTERNATOR AND BATTERY. IF BMW HAS BEEN SUED BECAUSE OF SUN ROOFS LEAKING BEFORE. MY CAR DIED IN A RAIN STORM AND IN HEAVY TRAFFIC CAUSING GREAT DANGER TO THE PASSENGERS. BMW SHOULD BE FORCED TO REPAIR THESE VEHICLES BEFORE SOMEONE IS INJURED OR KILLED. AND STOP ACTING LIKE THEY HAVE NEVER HEARD OF THIS PROBLEM BEFORE.
