Toyota Corolla electrical problems

AFTER REPLACING THE ALTERNATOR IN MY 2009 COROLLA IN JULY 2015. MY TIMING CHAINS AND WATER PUMP MALFUNCTIONED WHILE DRIVING ON THE HIGHWAY. I WAS UNAWARE AND SO WAS THE MECHANIC THAT THE TIMING BELTS WERE DAMAGED UNTIL AFTER THE WATER PUMP AND SERPENTINE BELT WAS REPLACED. DUE TO TIMING ISSUES FROM THE PREVIOUS MALFUNCTIONS, I AM NOW IN NEED OF A NEW MOTOR. MY VEHICLE HAS ALL REQUIRED REPAIRS OR MAINTENANCE COMPLETED AS SCHEDULED AND MY VEHICLE HAS NOT EVEN MADE IT TO 80,000 MILES.

WHEN I AM DRIVING THE VEHICLE THE RADIO/NAVIGATION SYSTEM TURNS OFF WITHOUT WARNING AND RESTARTS IN ABOUT 10 SECONDS. THIS HAPPENS A COUPLE OF TIMES A DAY. THE RADIO/NAVIGATION ALSO FREEZES AND YOU HAVE TO TURN THE CAR OFF AND BACK ON TO UNFREEZE IT. IT DOES THIS ON ALL TYPE OF ROADS, SMOOTH OR ROUGH, STRAIGHT OR CURVED. TOOK CAR TO THE DEALER SEVERAL TIMES AND THEY SAY ITS A KNOWN PROBLEM AND THEY ARE WAITING FOR A FIX FROM TOYOTA USA. AFTER THE THIRD COMPLAINT THEY SAID THEY REPLACED THE HEAD UNIT AND IN A WEEK THE PROBLEM RETURNED. I SUSPECT ITS A PROBLEM IN THE WIRING HARNESS.

7.5Y OLD COROLLA LE WITH 61,000 MILES OF GENTLE DRIVING/EXCELLENT MAINTENANCE, ALL OF A SUDDEN, THE ALTERNATOR FAILED AND THE CAR STEERING WHEEL IS LOCKED, THROWING ME INTO PANIC. I MANAGED TO PULL INTO A BANK PARKING LOT AT CHASE BANK ON 161 W SPRING CREEK PKWY, PLANO. MY PREVIOUS CAR WAS 1995 COROLLA, HAD SAME EXPERIENCE. I WOULD NEVER FEEL SAFE IN THESE VEHICLES. I FEEL THESE DENSO ALTERNATORS MAY BE DEFECTIVE AT SUCH LOW MILEAGE AND GENTLE USE. ANYONE ELSE HAVE SIMILAR ISSUE WITH DENSO ALTERNATOR [MODEL 104210-5480]?

AIRBAG LIGHT KEEPS STAY ON WHEN DRIVING, REGARDLESS OF WHERE TO DRIVE. HAVING THE VEHICLE CHECKED AT TOYOTA DEALER IN CONCORD, CA. THEY FOUND SPIRAL CABLE, LOCATED ON OR AT STEERING COLUMN, DEFECTIVE. AND IF LEFT UNFIXED, ACCORDING TO MY UNDERSTANDING, THE AIRBAG ON DRIVER SIDE POTENTIALLY UNEXPECTED DEPLOYED OR WONT DEPLOY AT ALL AT TIME OF ACCIDENT. THIS IS A SCARY SAFETY CONCERN TO ME, COSTLY BUT IT NEED TO BE FIXED AS SOON AS POSSIBLE. HOPE TOYOTA WILL COVER OR SHARE THE COST WITH ME, ~$500 AT ESTIMATE.

HORN FAILED TO HONK WHEN NEEDED. IT DID NOT WORK WHILE VEHICLE WAS IN MOTION ON A HIGHWAY, IT DID NOT WORK ON A CITY STREET, IT DID NOT WORK PARKED IN MY DRIVEWAY. THE WIRE BECAME SEPARATED AND THERE WAS A VOID, THE WIRE COVER STAYED INTACT UNTIL I REMOVED THE CONNECTOR FROM THE HORN. I HAD TO CONNECT A NEW WIRE FROM THE EXISTING WIRE AND RECONNECT TO THE HORN. ALL IS FINE NOW.

DRIVER SIDE POWER WINDOW SWITCH STARTED SMOKING AND I HAD TO TAKE IT OUT TO PREVENT A FIRE. ONE OF THE SWITCHES WOULD NOT OPERATE FREELY AND SEEMED TO GET STUCK. THOUGHT I WAS GOING TO HAVE A FIRE AND WHEN I REMOVED IT I FOUND COMPONENTS MELTED. CANNOT OPERATE WINDOW AND IT IS IN OPEN POSITION. VEHICLE WAS MOVING AT THE TIME AND I HAD TO RETURN TO HOME AND PARK SINCE SWITCH WAS SMOKING.
