2005 CADILLAC DEVILLE Electronic Stability Control Esc Problems

I WAS HIT HEAD-ON. THE IGNITION TURNED OFF AFTER BEING HIT AND THE SEAT- BELTS DID NOT DEPLOY. I STOPPED AND MY HAND WAS ON THE HORN BUT THE PERSON DID NOT SLOW DOWN OR STOP.I WAS ON A CITY STREET.I WAS HURT AND HAD NECK SURGERY. GM IS TELLING ME THEY WILL LOOK BACK INTO IT AFTER DENIAL THAT WAS IT DUE TO THE RECALL. THEY SOLD THE CAR AS SALVAGE WHEN THE INSURANCE TOTALED IT. THE CAR WAS THEN SOLD WITH A SALVAGE TITLE. THEY REPLACED THE IGNITION AFTER TELLING ME MY ACCIDENT INJURIES WAS NOT DUE TO THE RECALL.

DRIVING MY DAUGHTER FROM SCHOOL ON I 95 IN CONNECTICUT NEAR STAMFORD AT APPROXIMATELY 12 MIDNIGHT, AND NOTED CHIMES RELATED TO SAFETY ALERTS FOLLOWING A PARTICULAR STRONG BUMP IN THE ROAD. FIRST ALERT WAS THAT THE ABS AND SUSPENSION SYSTEM WAS INACTIVE, NEXT AIRBAG WAS NOT FUNCTIONING AND THEN ELECTRICAL CHARGE WAS LOW. ATTEMPTED TO FIND A SAFE PLACE TO STOP THE CAR; EVENTUALLY ALL WARNING LIGHTS CAME ON AND ALL SYSTEMS IN THE CAR BEGAN TO FAIL - COULD NOT OPEN WINDOWS, COULD NOT CONTACT ONSTAR, LIGHTS INSIDE THE CAR, SPEEDOMETER, HAZARD LIGHTS, TURN SIGNALS AND THE HEADLAMPS. EVENTUALLY USED STREET LIGHTS TO GUIDE US TO EXIT ON I 287 IN WHITE PLAINS, NY. ONCE WE FOUND A SAFE SPOT OFF THE ROAD, WE TURNED OFF THE CAR, BECAUSE WE DID NOT KNOW WHAT THE ISSUE WAS (?ENGINE, ?FIRE RISK, ?WOULD POWER STEERING / BRAKES FAIL NEXT). CAR TOWED...
