2008 Chevrolet Tahoe latches/locks/linkages problems

“PASSENGER SIDE DOOR LOCK STARTED HAVING PROBLEMS. WOULD WORK OCCASIONALLY. NOW, IT WON'T WORK AT ALL. HAS TO BE MANUALLY PULLED UP TO UNLOCK AND PUSHED DOWN TO LOCK. I NOTICED OVER 450 COMPLAINTS FROM OTHERS ABOUT THE ACTUATORS GOING OUT ON THEIRS TOO. SEEMS TO BE A PROBLEM. *TR”

“TL* THE CONTACT OWNS A 2008 CHEVROLET TAHOE HYBRID. THE CONTACT STATED THAT THE REAR HATCH DOOR FAILED TO UNLOCK. THE FAILURE RECURRED ON SEVERAL OCCASIONS. ON A SEPARATE OCCASION, WHILE DRIVING AT APPROXIMATELY 20 MPH, THE VEHICLE STALLED CAUSING ANOTHER VEHICLE TO CRASH INTO THE REAR OF THE CONTACT'S VEHICLE. A POLICE REPORT WAS FILED AND THERE WERE NO INJURIES REPORTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 117,475.”

“TL* THE CONTACT OWNS A 2008 CHEVROLET TAHOE. THE CONTACT STATED THAT THE FRONT DRIVER AND PASSENGER SIDE EXTERIOR DOOR HANDLES WERE FRACTURED. IN ADDITION, THE CHROME PEELED OFF OF THE FRONT PASSENGER SIDE INTERIOR DOOR HANDLE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER TWICE AND THE EXTERIOR DOOR HANDLE WAS REPLACED EACH TIME. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE VIN WAS UNAVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000. RK”

“REAR DOOR LOCKS (ACTUATORS) STOPPED WORKING. FIRST PASSENGER REAR LOCK FAILED TO OPEN OR CLOSE. THIS HAPPENED AFTER WARRANTY COVERAGE HAD ENDED. AFTER SOME RESEARCH I HAVE FOUND OUT THAT THIS IS A WIDESPREAD GM ISSUE ESPECIALLY WITH 2008-09 GM SUV TYPE OF VEHICLES. MY UNDERSTANDING IS THAT THE ACTUATOR MOTOR FAILS. IT IS ALSO MY UNDERSTANDING THAT THIS ELECTRICAL FAILURE IS DUE TO A VERY INEXPENSIVE ELECTRICAL ACTUATOR IS USED FOR THE LOCKING MECHANISM. THIS IS A REAL SAFETY ISSUE AND I AM WONDERING WHEN GM WILL BE HELD ACCOUNTABLE. *TR”

“A FEW YEARS AGO ALL THREE DOOR LOCKS WENT AT THE SAME TIME ON MY 2008 TAHOE. I TOLD MY DEALER THIS SEEMS VERY UNUSUAL. ASKED IF THERE IS A RECALL AND HE SHRUGGED HIS SHOULDERS. I AM NOT SURE OF THE EXACT DATE OTHER THAN TO TELL YOU IT WAS A FEW YEARS AGO. A FEW MONTHS AGO LEFT BLINKER WONT WORK. TOOK TO DEALER AGAIN. SAID TO BRING IT BACK AS THEY NEEDED MORE TIME TO WORK ON IT AND THINK I NEEDED AN ENTIRE NEW FUSE BOX. SATURDAY OCT. 5, 2013 HEADLIGHTS CAME ON WHILE PARKED IN PARKING LOT. NEXT DAY IT WAS TOTALLY DEAD. TRIED CHARGING IT AND HEADLIGHTS CAME ON AND WOULD NOT SHUT OFF. HAD TO DISCONNECT FUSES AND BATTERY. WEIRD MESSAGES KEEP POPPING UP ON DASHBOARD SUCH AS CHECK TIRE PRESSURE. IT WILL SAY REAR BUT ACTUALLY IT IS THE FRONT. SOMETIMES IT ISN'T ANY TIRE THAT IS LOW. CALLED CHEVY CUSTOMER SERVICE AND ASKED WHY THERE IS NO RECALL AND THEY SAID IT IS YOUR RESPONSIBILITY TO DO SO. I RESEARCHED EDMUNDS.COM AND FOUND 454 MESSAGES FROM PEOPLE WHO HAVE THE SAME ELECTRICAL PROBLEMS. CHEVY SAID TO CONTACT YOU. *TR”

“REAR PASSENGER DOOR ELECTRIC LOCK ACTUATOR FAILED RESULTING IN NO WAY TO OPEN THE DOOR WITHOUT MANUALLY UNLOCKING IT FROM THE INSIDE. IN THE EVEN OF AN EMERGENCY, THERE WOULD BE NO WAY TO OPEN THE DOOR FROM OUTSIDE OF THE VEHICLE OR FROM THE LOCK SWITCH ON THE DRIVER DOOR. IN ADDITION, THERE IS NO KEY LOCK ON THIS DOOR FROM THE OUTSIDE. I HAVE LEARNED THAT THIS IS A VERY COMMON PROBLEM ON 2008 CHEVROLETS, WHICH HAS COST CONSUMERS A HUGE AMOUNT OF MONEY IN ADDITION TO SUBJECTING THEM TO SERIOUS SAFETY CONCERNS. I WAS THE VICTIM OF A THEFT WHEN A PASSENGER DID NOT MANUALLY LOCK THE DOOR AND SEVERAL DAYS LATER WHEN I WAS PARKED IN A PARKING GARAGE SOMEONE ENTERED MY VEHICLE AND STOLE PERSONAL PROPERTY. THIS WOULD NOT HAVE OCCURRED IF THE LOCK ACTUATOR HAD FUNCTIONED PROPERLY AND LOCKED THE DOOR WHEN I LOCKED THE OTHERS. TO DATE, CHEVROLET HAS ACKNOWLEDGED THIS ISSUE BUT REFUSED TO DO ANYTHING TO CORRECT IT WITHOUT AN APPROXIMATE CHARGE OF $300 - $400 PER DOOR. *TR”
