2009 CADILLAC DTS Unknown Or Other Problems

CANT BRING DRIVER OR PASSENGER SEATS UP OR DOWN RESULTING IN UNCOMFORTABLE DRIVING POSITION IN DRIVE, NEUTRAL, PARK, ALL GEARS. DISTANCE SENSORS MALFUNCTION FREQUENTLY WHEN GOING INTO REVERSE.

LANE DEPARTURE SYSTEM HAS GONE OUT TWO TIMES IN LESS THAN 45,000 MILES. THIS IS A SYSTEM TO WARN YOU WHEN YOU CROSS OVER INTO ANOTHER LANE.

VEHICLE LOCKS ITSELF. "CHECKED" THREE TIMES PREVIOUSLY, NOTHING FOUND. THEN BACK PASSENGER SIDE LOCK FAULTY & REPLACED. ON 6/2/15 I TOOK MY CAT TO THE VET, REMOVED THE KEYS FROM THE IGNITION, DID NOT LOCK THE DOOR, PLACED THE KEYS ON THE CAT CARRIER, CLOSED THE DRIVER'S DOOR, WALKED AROUND TO PASSENGER SIDE TO GET THE CAT. BEFORE I COULD OPEN PASSENGER DOOR, CAR LOCKED ITSELF. WITNESSES 6-8 PEOPLE, INCLUDING MYSELF, TRYING TO EITHER BREAK A WINDOW OR PICK THE LOCK. CITRUS HTS CA. FIRE DEPT. CALLED. THE BACK DRIVER'S 'SIDE WINDOW WAS BROKEN WITH A TOOL I HAVE NEVER SEEN BEFORE. ALARM DID NOT GO OFF. NEITHER THE DOOR BUTTONS, THE DOOR UNLOCK RELAY SWITCH NOR THE DOOR HANDLES WOULD WORK MANUALLY. AFTER THE GLASS WAS BROKEN OUT AND AFTER THE 3RD TIME TRYING THE KEY, DOOR UNLOCKED/ALARM WENT OFF. FIRE DEPT SAID NOT TO DRIVE THE CAR UNLESS...
