NHTSA Complaint #10575879 — 2006 GMC YUKON

THE REAR LIFTGATE WILL NOT UNLOCK OR OPEN & REAR LIFTGATE WINDOW WILL NOT UNLOCK OR OPEN. THIS IS A SIGNIFICANT SAFETY HAZARD FOR PERSONS TRAVELING IN VEHICLE, AS THERE WOULD NOT BE ANY MEANS TO EXIT THE REAR OF THE VEHICLE VIA THE REAR LIFTGATE OR REAR LIFTGATE WINDOW IN AN EMERGENCY (ESPECIALLY FOR MY CHILDREN WHO SIT IN THE 3RD ROW OF SEATS) ALL 4 STANDARD DOORS STILL LOCK/UNLOCK BOTH MANUALLY AND WITH THE REMOTE CLICKER, HOWEVER, THE REAR LIFTGATE NO LONGER UNLOCKS OR OPENS MANUALLY OR WITH THE REMOTE CLICKER. THIS DESIGN DEFECT OF THE REAR LIFTGATE AND REAR LIFTGATE WINDOW ON THE GMC YUKON IS A SERIOUS HAZARD TO THE SAFETY OF PASSENGERS. NOW THAT THE REAR LIFTGATE AND REAR LIFTGATE WINDOW IS "FROZEN" IN THE LOCKED POSITION, THERE WOULD BE NO WAY TO EXIT THE INTERIOR OF THE VEHICLE FROM THE REAR LIFTGATE OR REAR LIFTGATE WINDOW SINCE THERE ARE NO MANUAL DOOR HANDLES OR LEVERS TO OPEN THE REARLIFTGATE OR ITS WINDOW FROM THE INTERIOR OR EXTERIOR OF THE VEHICLE. PER THE MECHANICAL DIAGNOSIS, THE POOR DESIGN OF THE REAR LIFTGATE 'HOUSING BOX' SURROUNDING THE LIFTGATE CABLE MECHANISM OVERHEATS AND HAS CAUSED THE 'HOUSING BOX' AND CABLE MECHANISM TO MELT, THUS RENDERING THE REAR LIFTGATE AND REAR LIFTGATE WINDOW NON-OPERATIONAL. WITHOUT THIS FUNCTIONING CORRECTLY, THERE IS NO MEANS TO ELECTRONICALLY OR MANUALLY UNLOCK OR OPEN THE REAR LIFTGATE OR REAR LIFTGATE WINDOW, THUS CAUSING A SIGNIFICANT SAFETY HAZARD TO PASSENGERS TRAVELING IN VEHICLE. *TR
