2006 GMC Sierra 2500

I WAS BACKING OUT OF MY DRIVEWAY (DOWN HILL SLOPE) AND LOST POWER STEERING AND BRAKING IN MY 2006 GMC 2500HD DIESEL TRUCK. I PUT THE TRANSMISSION IN NEUTRAL AND DEPLOYED THE EMERGENCY BRAKE TO STOP. THE MECHANIC DETERMINED THE POWER STEERING PUMP HAD FAILED AND THIS RESULTED IN THE HYDRO BOOST FAILURE WITH SUBSEQUENT BRAKE LOSS. AFTER REPLACING THE POWER STEERING PUMP THE POWER STEERING LINES SPLIT TWO WEEKS LATER. *TR

WHILE BRAKING AT LOW SPEEDS AND COMING TO A FULL STOP, TRUCK LURCHES FORWARD AND BRAKE PEDAL GOES DOWN 1/8 OF AN INCH. DRIVER MUST USE MORE BRAKE TO STOP TRUCK ( THIS IS WITH NO LOAD IN TRUCK AT ALL, ONLY PASSENGER ). ALSO WHILE STOPPED AND TURNING THE WHEEL LEFT OR RIGHT TO PARK, STEERING WHEEL LOOSES POWER STEERING UNTIL BRAKE IS RELEASED AND TRUCK STARTS ROLLING. HAD TRUCK LOOKED AT TWICE BEFORE AT DEALER FOR SAME PROBLEM ( ONCE AT 32,000 AND AGAIN AT 35,000 ) AND WAS TOLD, AS LONG AS NO HARD CODES OR FAILURES ARE FOUND, THEY WERE UNABLE TO ADDRESS THE ISSUE. *JB

TRUCK WAS PARKED IN GARAGE ON A FRIDAY NIGHT, WITH NO PROBLEMS. STARTED TRUCK SATURDAY AM TO BACK OUT OF THE GARAGE TO HOOK UP A TRAILER. I PUT THE TRUCK IN REVERSE, THEN DISCOVERED IT WOULDN'T STEER AND IT WOULDN'T STOP. NEARLY TOOK OUT THE SIDE OF THE GARAGE DOOR WITH THE MIRROR, NOT TO MENTION, NEARLY RUNNING OVER ONE OF MY KIDS! I HAD TO ENGAGE THE EMERGENCY BRAKE IN ORDER TO GET THE VEHICLE TO STOP - HALF IN AND HALF OUT OF THE GARAGE. I SHUT THE TRUCK OFF AND RESTARTED IT, BUT NOTHING CHANGED. CALLED A FLATBED TRUCK TO TAKE THE TRUCK TO THE DEALERSHIP. POWER STEERING PUMP HAD FAILED AND THEY REPLACED IT. I'M VERY LUCKY THAT I WASN'T PULLING THE TRAILER WHEN THIS HAPPENED, AS I COULD HAVE BEEN KILLED, OR KILLED SOMEONE ELSE. VERY SCARY SITUATION. THERE HAD BEEN NO TROUBLE WITH THE BRAKES OR STEERING LEADING UP TO THIS INCIDENT - IT WAS JUST BOOM - IT HAPPENED. I PURCHASED THIS DIESEL TRUCK NEW, AND HAVE HAD THE DEALERSHIP DO ALL SCHEDULED MAINTENANCE. IT HAS NEVER BEEN INVOLVED IN ANY ACCIDENT, AND IT IS KEPT INSIDE A GARAGE WHEN NOT IN USE. *TR

TL*THE CONTACT OWNS A 2006 GMC SIERRA 2500. THE FLY WHEEL, WHICH RUNS WITH THE TRANSMISSION AND HELPS CHANGE GEARS HAS HAD TO BE REPLACED THREE TIMES WITHIN TWO YEARS. WHILE DRIVING APPROXIMATELY 10 MPH DURING THE FIRST FAILURE, THERE WAS A LOUD CLICKING NOISE AND IT BECAME LOUDER OVER TIME. THE DEALER STATED THE VEHICLE WAS OPERATING NORMALLY. A FEW WEEKS LATER, THE NOISE WAS MUCH LOUDER; HOWEVER, A DIFFERENT DEALER 2 HOURS AWAY DIAGNOSED THE VEHICLE AND STATED THAT THE FLY WHEEL FAILED. AFTER BEING REPAIRED 24,000 MILES AND A YEAR LATER, THE FAILURE RECURRED. THE FLY WHEEL WAS REPLACED AGAIN AND LASTED 5 MONTHS BEFORE IT FAILED. THE POWER STEERING SHAFT ALSO NEEDED TO BE REPLACED DUE TO IT BEING WORN OUT AND FAILED AGAIN NINE MONTHS LATER. THE FAILURE MILEAGE WAS 22,800 AND THE CURRENT MILEAGE WAS 55,000. UPDATED 06/08/09 *BF THE POWER STEERING GEAR WAS LEAKING DUE TO LEAKING GEAR ASSEMBLY, THE HVAC BLOWER WAS INOPERATIVE, THE FLYWHEEL WAS CRACKED. THE DEALER REPLACED THE STRIPPED AND BROKEN EXHAUST STUDS. UPDATED 06/18/09.*JB

TL*THE CONTACT OWNS A 2006 GMC SIERRA 2500. WHILE ATTEMPTING TO EXIT A PARALLEL PARKED POSITION, THE POWER STEERING FAILED. THE STEERING WHEEL WAS ONLY ABLE TO BE TURNED ONE QUARTER TURN IN EITHER DIRECTION. THE VEHICLE WAS TAKEN TO A SERVICE DEALER ON THREE OCCASION, WHERE THEY WERE UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. THE MANUFACTURER STATED THAT WITHOUT A RECALL THEY ARE UNABLE TO REPAIR IT. THE FAILURE MILEAGE WAS 650 AND THE CURRENT MILEAGE WAS 3745.

DT*: THE CONTACT STATED WHILE ATTEMPTING TO EXIT A PARALLEL PARKED POSITION, THE POWER STEERING FAILED. THE STEERING WHEEL WAS ONLY ABLE TO BE TURNED ONE QUARTER TURN IN EITHER DIRECTION. THE VEHICLE WAS TAKEN TO A SERVICE DEALER, WHERE THEY WERE UNABLE TO DETERMINE THE CAUSE OF THE PROBLEM. THE MANUFACTURER WAS ALSO NOTIFIED. UPDATED 08/27/07 *TR

VEHICLE- 2006 GMC SIERRA 2500HD 4X4 DURAMAX/ALLISON THERE IS A VERY NOTICEABLE CLUNK/LOOSENESS IN THE STEERING. I HAVE GREASED/LUBRICATED THE WHOLE STEERING MECHANISM WITH NO REDUCTION IN THE PROBLEM. MY FEAR IS THE LOOSENESS WILL RESULT IN A COMPLETE FAILURE OR LOSS OF STEERING. PRIOR TO THAT I FEAR POOR DRIVING/MANEUVER ABILITY WHILE THIS ISSUE PERSIST. *JB

DT*: THE CONTACT STATED THE VEHICLE'S HYDROBOOST WAS TOO SMALL FOR THE TRUCK AND MADE TOO MUCH NOISE WHEN THE BRAKES OR STEERING WERE USED. THE DEALER DETERMINED THE VEHICLE HAS NO PROBLEMS, BUT THE CONTACT EXPRESSED THERE WILL BE DIFFICULTY DOING TOWING WORK PARTICULARLY GOING UPHILL AND DOWNHILL. THE VEHICLE IS ONLY TWO MONTHS OLD AND HAS BEEN DEMONSTRATING THIS PROBLEM SINCE THE BEGINNING OF THE SECOND MONTH.
