2009 GMC Yukon Hybrid

ALL THREE OF MY DOOR LOCKS NO LONGER LOCK ELECTRONICALLY. THEY MUST BE LOCKED MANUALLY. I HAVE TWO CHILDREN AND THIS IS A MAJOR SAFETY CONCERN. MANY COMPLAINTS HAVE BEEN FILED TO GM INDICATING THAT THIS IS A MANUFACTURING ERROR. MY CAR HAS 85000 MILES AND MANY THAT HAVE COMPLAINED HAVE FAR LESS. THIS IS CLEARLY AN ISSUE THAT SHOULD BE RECALLED. I REACHED OUT TO GM WITH NO SOLUTION OFFERED OTHER THAN THEM BASICALLY SAYING I AM ON MY OWN. THEY DID OFFER TO HELP ME FIND A LOCAL DEALER I COULD SHELL OUT MY MONEY TO. PLEASE HELP. THIS ISSUE OCCURS WHEN THE CAR IS AT REST AND IN MOTION.

UPON BEING STOPPED AT A LIGHT AT A MAIN INTERSECTION AND THEN MAKING A LEFT HAND TURN, THE VEHICLE SHUT DOWN AND THE CHECK ENGINE LIGHT CAME ON THE PANEL. WE WERE ABLE TO COAST TO THE SIDE OF THE ROAD. AFTER A FEW MINUTES, THE VEHICLE STARTED UP FOR ABOUT 2MILES THEN SHUT OFF AGAIN. THE DEALER WAS NOT ABLE TO REPLICATE AND SAID NO ISSUES FOUND. THEY GAVE US THE VEHICLE BACK ONLY TO HAVE THE SAME ISSUE 5 DAYS LATER IN WHICH THE VEHICLE WAS TOWED BACK TO THE DEALER. DIAGNOSTICS THEN SHOWED A NEW BATTERY WAS NEEDED (?) AND A SEALANT RESEALED. WELL, A FEW DAYS LATER (LESS THAN A WEEK) IT HAPPENED AGAIN. THE DEALER HAS SINCE HAD THE VEHICLE, CLAIMING NOTHING IS WRONG AND HAS NOT BEEN ABLE TO REPLICATE. (ALL INSTANCES WERE DURING CONSTANT RAINFALL AND THE VEHICLE BEING DRIVEN AT LEAST 15-20MINUTES IN THE RAIN. ) WE BOUGHT THE VEHICLE USED, BOUGHT A WARRANTY AND ARE NOW STUCK WITH TRADING IN THE VEHICLE!! *TR

3 OF THE 4 DOOR LOCKS FAILED TO WORK AS INTENDED, I.E., WITH FOB AND HAD TO BE MANUALLY MANIPULATED TO OPEN DOORS. ONE DOOR COULD BE OPENED WITH KEY. ONE DOOR COULD ONLY BE OPENED IF LOCK WAS PULLED UP MANUALLY - IT WOULD LOCK AUTOMATICALLY, BUT TOOK MANUAL INTERVENTION TO GET THE LOCK IN THE UN-LOCK POSITION. UNLESS THERE WAS AN ADULT IN THIS POSITION TO OPEN THE LOCK, THE DOOR COULD NOT BE ACCESSED FROM THE OUTSIDE. THIS WAS A REAR PASSENGER DOOR AND CAUSED GREAT CONCERN WHEN CHILDREN WERE IN THE CAR. I HAVE HAD THE 3 LOCKS REPLACED AT A GREAT DOLLAR COST, BUT COULD NOT IN GOOD CONSCIENCE HAVE CHILDREN IN THE REAR SEAT WITHOUT HAVING IT DONE. I HAVE REQUESTED REIMBURSEMENT FROM GMC AS I DO NOT BELIEVE A 75% FAILURE RATE ON DOOR LOCKS IS ACCEPTABLE SAFE PERFORMANCE OF THIS VEHICLE. *TR

WHILE DRIVING ON THE HIGHWAY BETWEEN 65-70 MILES AN HOUR MY VEHICLES CHECK ENGINE LIGHT CAME ON AND LA MESSAGE OF ENGINE POWER REDUCED APPEARED. THE VEHICLE LOSS POWER BUT I WAS ABLE TO MAKE IT TO THE SHOULDER SAFELY. THE CAR WOULD NOT TURN ON AND I HAD TO CAL AAA TO TAKE MY CARE TO THE DEALER. THE DEALER SAID THAT THE VALVE BODY INTERNALLY SHORTED THE MEMORY CIRCUIT AND THE CRANKSHAFT SENSOR SHORTED. THE DEALER SAID THAT THEY FOUND THE HARNESS FOR THE CRANKSHAFT HAD MELTED AND SHORTED OUT THE SENSORS. THEY REPAIRED THE HARNESS, REPLACED THE SHORTED OUT SENSOR AND REPLACED THE VALVEBODY/TCM. DO NOT KNOW WHAT CAUSED THE VALVE BODY TO SHORT AND CAUSE THE CRANKSHAFT SENSOR TO MELT. *TR

I GOT TO SHOULDER SAFELY; TOWED TO GMC DEALER - RESULT HYBRID FAULT CODE BUT NO CAUSE DETERMINED.
