2009 LEXUS IS 250 Electrical System Problems

MELTING DASHBOARD RECALL. I HAVE A 2009 LEXUS IS 250 MELTING CHIPPED DASHBOARD AND DOORS. IT'S VERY HARD TO SEE WHILE DRIVING DUE TO THE FACT THAT THE DASHBOARD CAUSES A GLARE IN THE WINDOW. ALSO THE SMELL OF MELTING PLASTIC DASH IS SICKENING. I HAVE RECENTLY TAKEN MY CAR TO A LEXUS DEALERSHIP TO HAVE SEWELL REPLACE THE AIRBAGS EVERY SINCE THEN MY NAVIGATION SYSTEM HAS BEEN MAKING WEIRD NOISES AND NOW IT'S COMPLETELY NOT WORKING BLACK SCREEN AND THE BUTTONS ON THE SIDE IS NOT WORKING. TO MAKE MATTERS WORSE MY AC IS ON AND I CAN'T TURN OFF BECAUSE OF THE BUTTONS ARE NOT WORKING. VERY FRUSTRATING AND I'M FREEZING.

A YEAR OR SO AGO MY CAR STARTED OVERHEATING. I STOPPED AND THE CAR SHUT OFF. THE COMPUTER SYSTEM FROZE AND SAID CHECKING SYSTEM AND SHOWED A DRAWING OF A CAR FRAME AND WHAT I GUESS IS THE HEAT SOURCE. I TOOK MY CAR TO THE MECHANIC AND HE REPLACED THE WATER PUMP. IT HAD CRACKED AND BOILED OVER AND EVER SINCE I HAVE HAD NOTHING BUT PROBLEMS. I'VE REPLACED THE ALTERNATOR, THE BATTERY, AND MY NAVIGATION SYSTEM IS BLANK AND COMPLETELY DOESN'T WORK. NOR DO THE BUTTONS AROUND IT. THE MOTHERBOARD IS FRIED. ALSO SOMETIMES WHEN I'M DRIVING AT NIGHT MY HEADLIGHTS TURN OFF IN THE PITCH BLACK DRIVING DOWN THE ROAD. MY DASHBOARD IS MELTING AND SINCE I'M A REALTOR WHO PUTS A LOT OF MILES ON HER CAR, I'M UNDERWATER. I'M EITHER GOING TO HAVE A HEAT STROKE DRIVING THAT SAUNA AROUND (THE HEAT IS STUCK ON)...
