2003 Kia Sorento Cruise Control Problems

WHILE DRIVING ON HIGHWAY APPROX 55MPH THE CAR JUST POWER. DEAD GAS PEDAL. HAD TO GET OVER TO SHOULDER BUT COULD NOT DUE TO THE STEERING LOCKING UP AND THE CAR SHUTTING DOWN. I GOT ASSISTANCE FROM PASSERBY WHO GO ME OVER TO SHOULDER. I STARTED UP THE CAR AND IT STARTED UP AND RAN WITH NO ISSUE. SUDDEN SHUT DOWM OF ENGINE IS VERY DANGEROUS. ONCE I GOT HOME AND HAD THE CAR CHECKED THE MECHANIC COULD NOT DUPLICATE THE INCIDENT IN ORDER TO MAKE REPAIRS. THIS HAPPENED 2 MORE TIMES AND ONLY HAPPENS TO ME ON HIGHWAY DRIVING. NEVER IN CITY DRIVING.

CRANKSHAFT PULLEY BOLT SHEERED OFF AND THEN THE PULLEY FELL OFF BUSTING THE POWER STEERING PULL COMPLETELY OFF. MAKING ME ALMOST LOOSE CONTROL AND FLYING OFF THE FREEWAY AT 60MPH WITH MY CHILD WITH ME, VERY SCARY. CAR WAS STILL UNDER WARRANTY BUT BECAUSE IT WAS THE BOLT THAT BROKE THE BOLT WAS NOT COVERED BY WARRANTY WORK. REPLACED ALL BY MANUFACTURE ON JULY 16TH 2012. COSTING $1,300. THIS LAST WEEK ON FATHERS DAY MY HUSBAND WAS DRIVING THE CAR TO GET HIS DAUGHTER AND THE BOLT SHEERED OFF AGAIN AND IT IS LESS THEN 12 MONTHS SINCE THIS HAPPENED BUT BECAUSE THE WARRANTY IS 12 MONTHS OR 12,000 MILES, WE WERE 1,000 MILES OVER AND NOW THE DEALERSHIP SAYS ITS OUR PROBLEM AND NOW WE HAVE TO BUY A WHOLE NEW ENGINE THIS TIME. OUR CAR WAS FIXED BY PORTLAND KIA AND NOW ITS AT WASHINGTON KIA, WASHINGTON KIA IS SAYING THAT PORTLAND DID IT INCORRECTLY AND THEY SHOULD MAKE THIS RIGHT BUT PORTLAND KIA IS NOT TAKING ANY FAULT FOR OVER TORQUING THE BOLD WITH 130 POUNDS OF A TORQUE. *TR
