2008 GMC Yukon Hybrid

MY TRUCK ACCELERATES AND ABRUPTLY STOPS WHILE SLOWING DOWN UNDER 20 MPH. UNDER 20 MPH THE ENGINE IS SUPPOSE TO SWITCH OVER TO CONNECT TO HYBRID BATTERY SYSTEM. SOMETIMES THE VEHICLE ABRUPTLY STOPS WHILE TURNING OR SOMETIMES THE CAR CUTS ALL THE WAY OFF. I PURCHASED THE VEHICLE IN 2010 AND I HAVE REPORTED THIS PROBLEM SINCE 2013. OVERTIME I TOOK THE VEHICLE BACK TO THE DEALER AND THEY WOULD TELL ME THAT THEY COULDN'T DUPLICATE THE PROBLEM. I RECENTLY HAD MAJOR ENGINE PROBLEMS INVOLVING THE LIFTERS ACCORDING TO THEIR DIAGNOSTIC MACHINE. THE COST WAS 6000 TO REPAIR. AFTER REPAIRING THE LIFTERS THE CAR STILL HAS THE SPONTANEOUS ACCELERATING AND STOPPING ISSUES.WE WERE TOLD BY THE SERVICE MANAGER AT CHEVROLET THAT WE SHOULD "JUST DUMP THE VEHICLE AND THEY HAD A HYBRID IN THE BACK THEY HAD OVER A MONTH AND THEY CAN'T FIGURE OUT WHATS WRONG WITH IT". I PAID OVER 38,000 FOR THIS TRUCK AT THEIR DEALER SHIP. IVE INVESTED THOUSANDS IN REPAIR COSTS. I WON'T SELL IT BECAUSE I KNOW IT HAS SAFETY HAZARDS. I DRIVE WITH CAUTION BECAUSE I DON'T KNOW WHEN TO EXPECT THE CAR TO ACCELERATE.

SOMETIMES WHEN I COME TO A STOP MY VEHICLE GOES INTO THE AUTOSTOP MODE, BUT WHEN I GO TO ACCELERATE IT DOESN'T COME OUT OF AUTOSTOP AND JERKS REALLY HARD THEN STALLS OUT. ONCE I PUT THE VEHICLE IN PARK AND RESTART IT, IT CRANKS RIGHT UP BUT THE CHECK ENGINE LIGHT COMES ON AND STAYS ON FOR ABOUT A DAY AND THEN GOES OFF ON IT'S OWN. I HAVE TAKEN THE VEHICLE TO GMC DEALERSHIP TWICE AND PAID OUT ABOUT $700 FOR REPAIRS THAT DID NOT SOLVE THE PROBLEM. THE DEALERSHIP CLAIMS TO NOT BE ABLE TO FIND ANY CODES EVEN WITH THE CHECK ENGINE LIGHT ON. I HAVE BEEN CLOSE TO BEING HIT FROM THE BACK ON AT LEAST 3 OCCASIONS BECAUSE THE VEHICLE INITIALLY MOVES SLOWLY BEFORE JERKING AND STALLING. PLEASE HELP MYSELF AND OTHERS WITH THIS SIMILAR PROBLEM GET HELP BECAUSE OBVIOUSLY THE DEALERSHIP ISN'T CONCERNED WITH OUR SAFETY AS WELL AS OUR CHILDREN.

75% OF THE ELECTRIC DOOR LOCKS ON THE ABOVE DESCRIBED GMC YUKON, INCLUDING BOTH REAR DOOR LOCKS HAVE FAILED IN THE LOCKED POSITION. THIS FAILURE MAKES IT DIFFICULT/IMPOSSIBLE TO OPEN THE DOORS - ESPECIALLY THE REAR DOORS. BECAUSE THE CAR HAS ONLY ONE EXTERIOR DOOR LOCK; IN ORDER TO OPEN THE INTERIOR MANUAL REAR DOOR LATCHES IN AN EMERGENCY, ONE MUST TRY TO CLIMB OVER/BETWEEN THE FRONT SEATS (THE HEAD RESTS ARE NO LONGER REMOVABLE) - A STRETCH OF 4'4" FROM THE EDGE OF THE FRONT SEAT TO THE LATCH WHICH IS LOCATED AT THE REAR OF THE REAR DOOR. SHOULD ONE ATTEMPT TO ACCESS THESE LOCKS THROUGH THE REAR TAILGATE, IT IS A LONG REACH OF 6' 6" OVER THE THIRD ROW SEATS. IN AN EMERGENCY SITUATION, THE ABOVE DESCRIBED FAILURE, CAN EASILY TRAP INFANTS AND CHILDREN IN THE BACK OF THE CAR, CREATING AN A SERIOUS HEALTH AND SAFETY PROBLEM. *TR

TL* THE CONTACT OWNS A 2008 GMC YUKON DENALI HYBRID. THE CONTACT STATED THAT WHILE DRIVING 15 MPH, HE APPLIED THE BRAKES BUT NOTICED THAT THE VEHICLE HAD INDEPENDENTLY CONVERTED FROM THE GASOLINE MODE TO ELECTRICAL HYBRID MODE. THE VEHICLE THEN STALLED BUT REGAINED POWER ONCE THE VEHICLE WAS AT A COMPLETE STOP. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION BUT THEY COULD NOT DIAGNOSE THE CAUSE OF FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 40,000.
