ELECTRICAL SYSTEM, LATCHES/LOCKS/LINKAGES
I HAVE A 2009 GMC SIERRA 2500 WITH 70,000 MILES. AT 39,200 MILES, THE ACTUATOR ON THE FRONT DRIVERS SIDE DOOR LOCK FAILED. THEN AT ABOUT 46,000 MILES THE ACTUATOR ON THE REAR DRIVERS SIDE DOOR LOCK FAILED. MY DOOR LOCKS NO LONGER AUTOMATICALLY LOCK AND UNLOCK WHICH CREATES A SAFETY HAZARD, PARTICULARLY IN THE CASE OF THE REAR DOOR LOCK BECAUSE IT CANNOT BE LOCKED OR UNLOCKED BY THE DRIVER WITHOUT EXITING THE VEHICLE AND CRAWLING THROUGH FROM THE PASSENGER SIDE. IF YOU DON'T MANUALLY LOCK THE REAR DOOR, A YOUNG CHILD COULD OPEN THE UNLOCKED DOOR WHILE THE VEHICLE IS IN MOTION; BUT IF YOU MANUALLY LOCK THE REAR DOOR, YOU CANNOT GET A CHILD OUT QUICKLY IN THE EVENT OF AN ACCIDENT BECAUSE IT IS IMPOSSIBLE TO ACCESS THE LOCK WITHOUT CRAWLING THROUGH FROM THE PASSENGER SIDE. DOOR LOCK ACTUATOR FAILURES SEEM TO BE A COMMON PROBLEM ON 2009 GENERAL MOTORS TRUCKS. MY FATHER ALSO HAS A 2009 GMC SIERRA 2500, AND ONE OF THE FRONT DOOR LOCK ACTUATORS FAILED ON IT. I HAD A 2009 CHEVROLET SILVERADO 3500 TRUCK FOR USE BY MY STAFF AND ONE OF THE REAR DOOR LOCK ACTUATORS FAILED ON IT. A FRIEND HAS A 2009 CHEVROLET SILVERADO 1500, AND ONE FRONT AND ONE REAR DOOR LOCK ACTUATOR FAILED ON HIS VEHICLE. AND, A GOOGLE SEARCH LED ME TO MANY POSTINGS AND COMPLAINTS RELATED TO DOOR LOCK ACTUATOR FAILURES ON 2009 GENERAL MOTORS TRUCKS AND SUVS. I HAVE BEEN UNABLE TO CONVINCE MY GM DEALER TO CORRECT THIS DEFECT - THEIR ESTIMATED COST TO REPLACE THE TWO ACTUATORS IS APPROXIMATELY $800.00 WHICH I SIMPLY CANNOT AFFORD TO PAY. *TR

SERVICE BRAKES
2007 GMC SIERRA CLASSIC WITH APPROXIMATELY 54,000 MILES WAS BEING DRIVEN INTO A GARAGE TO HAVE WHEELS BALANCED. AS THE TECHNICIAN APPLIED THE BRAKES ENTERING THE GARAGE, THE BRAKE LINES ON THE FRONT DRIVERS SIDE OF THE VEHICLE RUPTURED AND THE BRAKE PEDDLE WENT TO THE FLOOR. BRAKE FLUID POURED OUT ONTO THE FLOOR AND THE BRAKES BECAME COMPLETELY UNUSABLE. IF THIS HAD HAPPENED A FEW HOURS EARLIER IN THE DAY AS I WAS TRAVELING ON STEEP MOUNTAIN HIGHWAYS IN WEST VIRGINIA I HAVE NO DOUBT AN ACCIDENT AND PROBABLE FATALITY WOULD HAVE OCCURRED. ALL RECOMMENDED MAINTENANCE HAD BEEN PERFORMED AT THE GM DEALER WHERE THE TRUCK WAS PURCHASED AND NO WARNINGS FROM GM WERE GIVEN THAT THE BRAKE LINES WERE SHOWING ANY SIGNS OF WEAR OR THAT A COMPLETE BRAKE FAILURE LIKE THIS COULD HAPPEN. *TR

SERVICE BRAKES
I WAS DRIVING IN A 40 MPH STREET WHEN I NOTICED THE TRAFFIC SIGNAL WAS ABOUT TO TURN RED WHEN I APPLIED THE BRAKES THE PEDAL WHEN DOWN TO THE FLOOR I LOST ALL BRAKES I SLOWED DOWN BY DOWN SHIFTING THE TRANSMISSION AND APPLYING THE EMERGENCY BRAKE. WHEN I PULLED OVER THERE WAS BRAKE FLUID LEAKING ALL OVER UNDER DRIVERS SIDE DOOR. UPON INSPECTION I NOTICED THE BRAKE LINES RUSTED OUT AND LOST ALL FLUID. I COULD HAVE BEEN KILLED THERE WAS NO WARNING. I NEEDED TO HAVE MY BRAKE LINES REPLACED I BELIEVE THIS IS A START OF SOMETHING BAD IF GM DOESN'T ACT ON THIS PROBLEM. *TR

SEATS
IF YOU RAISE THE REAR SEAT HEAD RESTRAINTS, THEY EASILY GO BACK DOWN. THERE IS NO LOCKING IN A HIGHER POSITION. ALSO THEY DO NOT GO UP HIGH ENOUGH TO SUPPORT AN ADULT OR SOMEONE ABOUT 5FT 6IN OR HIGHER. THERE IS ALSO NO HEAD RESTRAINT IN THE MIDDLE BACK SEAT. I AM VERY CONCERNED THESE ISSUES COULD CAUSE SERIOUS INJURY TO REAR SEAT OCCUPANTS IN AN ACCIDENT. *TR

SERVICE BRAKES
I WAS TAKING MY 4 YR OLD TO SCHOOL THIS MORNING WITH HIS 1 YR OLD SISTER WHEN THE BRAKES COMPLETELY FAILED. UPON APPROACHING A RED STOPLIGHT AT 30 MILES PER HOUR WITH THREE CARS STOPPED AHEAD OF ME I PRESSED THE BRAKE PEDAL AND IT WENT COMPLETELY TO THE FLOOR. I PULLED GEARSHIFT TO THE LOW POSITION AND SWERVED INTO THE VACANT LEFT HAND TURNING LANE TO AVOID THE CARS STOPPED AT THE LIGHT. THEN TURNED HARD RIGHT AS TO NOT ENTER THE BUSY INTERSECTION IN FRONT OF ME WITH NO AVAIL. SOMEHOW WE WERE NOT HIT BY ANOTHER VEHICLE. AT THAT TIME I PULLED VEHICLE OVER TO THE SHOULDER OF THE ROAD WHICH ENDED ABRUPTLY AND TURNED INTO A GRASSY AREA OF A BASEBALL FIELD WHERE THE VEHICLE FINALLY CAME TO A STOP.GM STATES THAT IF THERE IS A BRAKE LINE FAILURE THE VEHICLE STILL HAS BRAKING ABILITY. I CAN TELL YOU FIRST HAND THAT IS A TOTALLY FALSE STATEMENT. MY VEHICLE DASH DID NOT DISPLAY ANY PROBLEM PRIOR TO THIS INCIDENT. WHEN VEHICLE WAS TOW TO MY HOME I PUT KEY IN THE IGNITION TO CHECK MY MILEAGE AND NOW A BRAKE FAILURE MESSAGE IS DISPLAYED.I AM VERY ANGRY WITH GM FOR NOT NOTIFYING ME OF THIS PROBLEM AND NEVER HAD ANY IDEA THERE WAS AN ON GOING ISSUE UNTIL TODAY. MYSELF AND MY TWO CHILDREN COULD HAVE BEEN KILLED TODAY BECAUSE OF THIS NEGLECT. PLEASE DO SOMETHING TO RECTIFY THIS PROBLEM BECAUSE MANY MORE GM VEHICLE WILL HAVE THIS PROBLEM AND INNOCENT PEOPLE AND THEIR FAMILIES WILL BE HURT OR EVEN DIE. *TR

SERVICE BRAKES
I WAS ON MY WAY HOME FROM AN EVENT THIS PAST SATURDAY HEADING TO DROP OFF MY SON. AFTER DROPPING HIM OFF I CONTINUED HOME. I WAS TRAVELING ABOUT 35 MPH WHEN THE LIGHT TURNED RED AND I DEPRESSED THE BRAKE AND WAS TERRIFIED WHEN IT WENT DOWN TO THE FLOOR. ALTHOUGH I HAVE AS ABLE TO COME TO A STOP WITHOUT INCIDENT I HAVE AS STILL TERRIFIED. I AM A DISABLED VETERAN WITH A HEART CONDITION AND COULD HAVE HAD A HEART ATTACK. I HAD MY TRUCK LOOKED AT BY MY CERTIFIED MECHANIC AND HE TOLD ME THAT MY BRAKE LINE RUPTURED DUE TO RUST AND IT WILL COST ME AROUND $1000.00 FOR REPAIRS. I HAVE HAD MANY MANY CARS AND TRUCKS IN MY LIFETIME AND NEVER EVER EXPERIENCED ANY PROBLEMS OF THIS NATURE. IT SEEMS TO ME THE MANUFACTURE WOULD ALLOW FOR THESE NORTHERN CONDITIONS WITH THE PARTS THEY USE IN PRODUCTION. *TR

EXTERIOR LIGHTING
FROM DAY ONE THE HEADLIGHTS ON OUR 2014 GMC SIERRA 1500 VEHICLE ARE USELESS. THE DO NOT LIGHT UP AT ALL AND IS A VERY BAD SAFETY HAZARD FOR ALL. WE CAN DRIVE DOWN THE ROAD ON HIGH BEAM AND NO ONE WILL FLASH US AT ALL. WE HAVE NOTIFIED THE DEALER AND GMC AND SEEM TO GET NO WHERE. THEY SAID THERE HAS BEEN A LOT OF COMPLAINTS FOR BAD VISABILITY WITH THE NEW SHUTTER HEADLIGHTS BUT GMC SAYS THEY LOOK PRETTY. WELL PRETTY DOES NOT HELP BEING ABLE TO SEE. I HAVE READ PAGES OF COMPLAINTS ABOUT HOW ANYONE THAT PURCHASED A 2014 GMC SIERRA 1500 CANNOT SEE AT NIGHT WHILE DRIVING AND AGAIN THIS IS A SERIOUS SAFETY HAZARD. THE 2014 GMC SIERRS 3500 HAS THE REGULAR HEADLIGHTS, WHY CANT THE 1500 HAVE THESE?? WE PAID $43,000 FOR THIS PICKUP AND CANT DRIVE IT AT NIGHT FOR THE FEAR OF HITTING ANIMALS, PEOPLE WALKING ETC. GMC SAYS OH WELL YOU BOUGHT IT YOUR FAULT, BUT WHO TAKES A TRIAL RIDE AT NIGHT?? IF WE COULD WE WOULD TRADE VEHICLE IN FOR A CHEVY, THEIR 2014 HAS REGULAR HEADLIGHTS. AGAIN I AM NOT THE ONLY ONE THAT IS HAVING HEADLIGHT PROBLEMS PLEASE SEARCH FOR COMPLAINTS ON THIS MATTER AND YOU WELL SEE HOW MANY PEOPLE ARE COMPLAINING AND GMC IS NOT TAKING THIS SERIOUS AT ALL!! IF WE CRASH AT NIGHT DUE TO OUR LIGHTS, WHICH WHERE WE LIVE IN NORTHERN MAINE, WE WILL DEFINITELY BE PUTTING SOME LAWYERS IN ON THIS MATTER AND GOING AFTER SOMEONE FOR NOT ADDRESSING THIS SAFETY HAZARD. *TR

AIR BAGS, STEERING
POWER STEERING STOPS WORKING ON SLOW RIGHT HAND TURNS. I SOMETIMES NEED TO BACK UP IN ORDER TO COMPLETE THE TURN. I ALSO END UP CROSSING INTO ONCOMING LANES IF NO TRAFFIC IS COMEING TOWARDS ME. IF THERE IS TRAFFIC I NEED TO STOP IN THE MIDDLE OF THE TURN UNTIL THE TRAFFIC CLEARS. THE "CHECK AIRBAG" LIGHT CAME ON AT 85000 MILES AFTER THE BATTERY DISCHARGED FROM THE VEHICLE SITTING TO LONG WITHOUT BEING DRIVEN. *TR
