2002 GMC Yukon Xl Problems

The contact owns a 2002 GMC Yukon XL. The contact stated while driving approximately 70 MPH, the contact started to slow for traffic and depressed the brake, and felt no braking. The contact had to depress the brake pedal to the floorboard. The contact stated that the brake warning light was illuminated. The contact was able to safely stop and drove the vehicle to his residence. The contact had taken the vehicle to a local dealer who diagnosed that there was a fractured parking brake spring. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 189,000.

AS VEHICLE COMES TO A SLOW STOP THE BRAKES FEEL AS IF THE RELEASE AND STILL ROLL ALSO WHEN PULLING INTO A DRIVEWAY OR PARKING SPOT THIS HAS HAPPED OFTEN.

WAS DRIVING APPROX 60MPH ON NEWLY PAVED 4 LANE HIGHWAY (US 31). VEHICLE BEGAN TO MAKE A NOISE AND THEN SHAKE. FRONT DRIVER'S SIDE TIRE WAS COMPLETELY DESTROYED WITH APPROX 80% OF THE TREAD AND BELT SEPARATED FROM THE TIRE AND NUMEROUS HOLES IN THE TIRE. MANY SHARP STEEL PRONG ENDS WERE STICKING OUT OF THE TIRE AND THE SEPARATED TREAD/BELT. DESTROYED THE WHEEL WELL COVERING. 2002 YUKON XL. TIRES HAD BEEN INSTALLED IN MARCH 2008. WHEN LOOKING AT THE FRONT PASSENGER SIDE TIRE, IT HAD NUMEROUS LARGE CRACKS FROM THE TREAD EXTENDING INTO THE SIDEWALL. TO AVOID HAVING ANOTHER BLOWOUT/SEPARATION, QUICKLY REPLACED THAT TIRE AND RETURNED BOTH TO THE DEALER WHERE PURCHASED. HAVING THE DEALER CONTACT COOPER AND INSPECT THE REAR 2 TIRES AS WELL (VISUAL INSPECTION DID NOT SHOW THE TREAD/SIDEWALL CRACKS). *TR

(1) NONE (2) PULLED OUT ON HWY AT NORMAL SPEED, LOUD WINING, AND LOUD POP.TRANSMISSION FAILED, LEFT WITH ONLY 2ND AND 3RD GEAR.(3) CALLED TRANSMISSION SHOP AND THEY DESCRIBED IN DETAIL THE FLAW THAT CAUSED FAILURE. THEY INFORMED ME THAT THIS WAS QUITE COMMON IN THIS MODEL. I FEEL THAT THIS SHOULD BE REPORTED AS A RECALL, TO CORRECT THIS DEFECT.

I SWERVED TO MISS A DEER AND I HIT A TREE RUNNING 47 MPH AND MY AIR BAGS DIDN'T DEPLOY AND NO ONE CAN TELL ME WHY. MY HUSBAND AND I WERE VERY LUCKY BUT WHY DIDN'T THE AIR BAGS DEPLOY? MY HUSBAND WAS OUT OF WORK FOR 5 MONTHS DUE TO TORN LIGAMENTS IN HIS SHOULDERS AND STILL HAS TO HAVE SURGERY.

TL* THE CONTACT OWNS A 2002 GMC YUKON XL. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 30 MPH, THE ENGINE STALLED WITHOUT WARNING. THE VEHICLE RESTARTED AFTER EIGHT ATTEMPTS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE CRANKSHAFT POSITION SENSOR WAS FAULTY. THERE WAS A RECALL ISSUED FOR THE 2001 GMC YUKON MODEL UNDER NHTSA CAMPAIGN ID NUMBER 07V521000 (ENGINE AND ENGINE COOLING). THE VEHICLE WAS CURRENTLY BEING REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 62,700.

PURCHASED A NEW 2002 GMC YUKON XL, AT ABOUT 6800 MILES THE STEERING DEVELOPED A RATTLE, DEALER UNDER WARRANTY REGREASED THE STEERING SHAFT, THIS HELPED FOR A ABOUT A YEAR AND IT STARTED AGAIN. DEALER RE-GREASED WITH WHAT THEY SAID WAS A NEW GREASE THAT SHOULD SOLVE THE RATTLE PROBLEM. IT HAS STARTED THE RATTLE AGAIN AND ONLY HAS 38000 MILES. I UNDERSTAND THERE IS A REDESIGNED STEERING SHAFT THAT SOLVES THIS RATTLE PROBLEM. HERE IS THE BULLETIN TO SOLVE THE POOR SHAFT DESIGN, SHOULD BE A RECALL BUT LOOKS LIKE GM IS ONLY REPLACING ON A CASE BY CASE ISSUE WAITING FOR YOUR WARRANTY TO BE OUT, AT WHICH TIME THEY CHARGE YOU FOR THE POOR DESIGN STEERING SHAFT.

DT*: THE CONTACT STATED IN NOVEMBER WHEN THE VEHICLE WAS TAKEN TO THE DEALERSHIP FOR ROUTINE SERVICE, THE DEALERSHIP NOTICED THE REAR ROTORS WERE HITTING THE INSIDE OF THE BACKING PLATES INSIDE THE HUB. ALSO, THE ROTORS WERE RUSTED. THE FRONT END WAS ALSO OBSERVED TO BE SHAKING. THE DEALERSHIP DETERMINED THE SHAKING WAS NORMAL 4X4 CHARACTERISTICS; HOWEVER THE DEALERSHIP INSTALLED A LUBE KIT THAT GOES ON THE STEERING COLUMN UNDERNEATH THE HOOD. THE SHAKING RETURNED AND THE DEALERSHIP INFORMED THE CONTACT THE LUBE KIT WAS NO LONGER A REMEDY FOR THIS SHAKING PROBLEM. THERE WAS NOT ANOTHER REMEDY OFFERED.

BROKEN EXHAUST MANIFOLD STUDS ARE CAUSING ENVIRONMENTAL HAZARD AND MAY LEAD TO FAILED CATALYTIC CONVERTER AND OTHER ENGINE PROBLEMS. THIS IS A MANUFACTURING DEFECT THAT SHOULD BE RECALLED, AS IT RENDERS THE VEHICLE EITHER UNUSABLE OR UNABLE TO PASS ENVIRONMENTAL TESTING. *TR

VEHICLE RAN OUT OF GAS, FUEL GAUGE READ 1/4 TANK

I SWERVED TO MISS A DEER AND I HIT A TREE RUNNING 47 MPH AND MY AIR BAGS DIDN'T DEPLOY AND NO ONE CAN TELL ME WHY. MY HUSBAND AND I WERE VERY LUCKY BUT WHY DIDN'T THE AIR BAGS DEPLOY? MY HUSBAND WAS OUT OF WORK FOR 5 MONTHS DUE TO TORN LIGAMENTS IN HIS SHOULDERS AND STILL HAS TO HAVE SURGERY.

WE PURCHASED THE 2002 YUKON FROM MCGUIRE DEALERSHIP IN NJ ITS BEEN CARED FOR TAKEN TO THE DEALERSHIP FAITHFULLY DRIVEN BY MY 50 YEAR OLD FATHER, WHEN FIRST DRIVING HE NOTICED THE PEDAL VIBRATING RAPIDLY DURING NORMAL BRAKE APPLICATIONS. THE ABS CONTROL VALVE WAS THE CULPRIT ALONG WITH A RUSTY WHEEL SENSOR. IT WAS REPLACED AT THE DEALER AND AFTER 5 YEARS THE FRAME OF THE TRUCK IS RUSTING AND ROTTING ALONG WITH SUSPENSION PARTS AND MOST OF ALL THE BRAKES. WE CAME CLOSE TO CRASHING ONE DAY WHEN THE PEDAL WENT STRAIGHT TO THE FLOOR, WE TAKE IT TO THE LOCAL FIRESTONE AND THEY TELL US ALL THE BRAKE LINES ARE RUSTED OUT ALONG WITH THE MASTER CYLINDER. WE REPLACED THE LINES AND MASTER CYLINDER WITH A HEFTY PRICE TAG. WE GET THE CAR BACK 3 DAYS LATER PEDAL GOES TO THE FLOOR AGAIN, BACK AT THE MECHANIC BOTH REAR CALIPERS ARE RUSTED AND LEAKING. WE REPLACED ALL 4 CALIPERS AND THE PROBLEM STOPPED BUT NOW THE FRAME IS RUSTING AND THE ABS IS STILL VIBRATING BADLY. LONG STORY SHORT GM NEEDS TO BE HELD ACCOUNTABLE FOR SELLING SUCH CHEAP CRAPPY TRUCKS, WE CAME CLOSE A FEW TIMES TO CRASHING, AND I FEEL SORRY FOR THE PEOPLE THAT HAVE LOST THEIR LIVES DUE TO THE NEGLIGENCE OF THE EMPLOYEES OF GM. *TR

DT*: THE CONTACT STATED WHILE TRAVELING 75 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE RESTARTED AND THE MANUFACTURER WAS ALERTED. UPDATED 11/9/2006 - THE VEHICLE STALLED THREE TIMES IN ONE DAY AND ANOTHER TIME ABOUT 16 MONTHS AGO. THE CONSUMER WAS TOLD BY A SERVICE MANAGER THAT THE PROBLEM WAS WITH A COMPUTER RING IN THE KEY SWITCH ASSEMBLY. *NM

WE ARE NOW REPLACING THE BUSHING IN THE STEERING COLUMN FOR THE SECOND TIME WITH LESS THAN 42,000 MILES. THIS COMPONENT WAS REPLACED ORIGINALLY AT 28,000 MILES AND HAS FAILED AGAIN. WITH THIS FAILURE HAS CAUSED LEFT WHEEL BEARING TO GO OUT. AT 58,000 MILE THE RIGHT WHEEL BEARING IS NOW IN NEED OF REPAIR, SHOULD HAVE GOTTEN THE EXTENDED WARRANTY, NONE OF THIS IS COVERED AFTER 36,000 MILES. ALSO, THE REAR AIR WILL EITHER BLOW COLD UNTIL THE THERMASTAT IS CHANGE TO THE RED SETTING COMPLETELY. WHEN TAKEN IN WITH THE INITIAL FAILURE OF THE STEERING COLUMN, I WAS TOLD THAT THE SETTING WORKED FINE BUT WOULD BE NOTED INCASE OF LATER FAILURE SO IT MIGHT BE COVERED UNDER WARRANTY.*AK

2002 GMC YUKON XL REAR TAILGATE GLASS FAILED/BROKEN HINGE DUE TO POOR DESIGN. THIS RESULTS IN THE REAR GLASS HELD ON BY ONE HINGE INSTEAD OF TWO. REAR GLASS DOES NOT CLOSE PROPERLY AND IS AT RISK TO DETACH FROM VEHICLE. MANY OWNERS OF THIS VEHICLE (AND SISTER VEHICLES TAHOE AND SUBURBAN) HAVE EXPERIENCED THIS DEFECT. GM FAILS TO ACKNOWLEDGE OR ASSUME RESPONSIBILITY. *TR

BOTH HEATED REARVIEW MIRRORS CRACK SIDE NEXT TO CAR AT HEATING ELEMENT AND THEN THE CRACK MOVES ACROSS THE MIRROR. *NM

GMC 2002, YUKON: THE REACTION SUNSHELL BROKEN INSIDE OF TRANSMISSION. ONLY 64,000 MILES. 1) NO EVENT LEADING TO FAILURE: CALLED GMC PETERSON IN GURNEE ILLINOIS, GMC KNOWS OF THIS PROBLEM AND IN FACT CHANGED THE DESIGN OF THE SUNSHELL YET WILL NOT RECOVER MY COST. I NOW LIVE IN MINNESOTA AND GMC HERE IS DOING THE TRANSMISSION FIX. 2) FAILURE AND CONSEQUENCES: COULD BE EXTREMELY SERIOUS IF DRIVING ON A BUSY HIGHWAY. LOSS OF POWER AND ACCELERATION COULD CAUSE AN ACCIDENT. 3) CORRECT FAILURE: GMC IS DOING NOTHING TO CORRECT THIS FAILURE THAT I KNOW OF. CUSTOMERS ARE BEING TOLD THAT THIS IS A RARE OCCURRENCE. HOWEVER, AFTER TALKING WITH GURNEE PETERSON GMC ILLINOIS AND VALLEY GMC FROM WACONIA MINNESOTA, THIS REPAIR IS NOT UNCOMMON AND IS OCCURRING EVERY COUPLE OF MONTHS. I FEEL THIS WARRANTS A CORRECTIVE ACTION. *NM

DURING ACCELERATION, TRANSMISSION LURCH AND SLIP OCCURRED CAUSING ENGINE TO OVER-REV RESULTING IN THE LOSS OF THIRD GEAR, FORTH GEAR, AND REVERSE. CAUSE WAS A MECHANICAL FAILURE INSIDE TRANSMISSION @ ONLY 46K MILES. TRANSMISSION RE-BUILD WAS NECESSARY. *NM

KNOCKING NOISE IS HEARD COMING FROM THE FRONT OF THE VEHICLE AND IS FELT AS A "CLUNK" THROUGH THE STEERING WHEEL. HAPPENS WHEN PARALLEL PARKING....TIGHT, SLOW TURNS IN REVERSE. FEELS LIKE GEARS IN THE DIFFERENTIAL ARE STICKING AND LURCHING. IT HAS BEEN HAPPENING ON AND OFF FOR A LONG TIME. *TR

EVENTS LEADING UP TO THE FAILURE: 2002 YUKON 73,000 MILES. NO PREVIOUS EVENTS LEADING UP TO THE PROBLEM. FAILURE/CONSEQUENCES: 2002 YUKON: I STARTED MY CAR AND ABS LIGHT STAYED ON. WHILE DRIVING, I COULD FEEL AN ABNORMAL VIBRATION THROUGHOUT MY CAR. (WITH MY TWO SMALL CHILDREN, WE PULLED OFF TO THE SIDE OF THE ROAD ON THE RIGHT OF WAY. I CUT OFF MY CAR (REMOVED KEY OUT OF IGNITION) AND THE CAR SOUNDED LIKE IT WAS STILL ON. CORRECT THE PROBLEM: I CALLED MY GMC DEALER IN AUSTIN TEXAS WHERE I HAD PURCHASED THE VEHICLE AND THE SERVICE MANAGER TOLD ME THAT HE HAS SEEN MANY INCIDENTS SUCH AS THIS. HE INDICATED THAT IF I LEFT THE ABS MOTOR RUNNING, THAT MY BATTERY WOULD DIE AND/OR THE MOTOR WOULD RUIN. SO, HE INSTRUCTED ME TO RAISE THE HOOD AND REMOVE THE 60AMP ABS FUSE. BY DOING SO, THE VIBRATION/MOTOR STOPPED. HE SAID TO BRING IT INTO THE GARAGE FOR SERVICE. HIS INITIAL GUESS WAS THAT IT WAS THE ABS MODULE OR EBCM NEEDED TO BE REPLACED. BECAUSE MY VEHICLE WAS NO LONGER IN WARRANTY, HE ESTIMATED THAT IT COULD COST ANYWHERE BETWEEN $1100.00-1900.00 DOLLARS. I HAVE DONE RESEARCH ON THE INTERNET AND THERE ARE MANY 1999-2004 GM SUVS AND TRUCKS WHICH HAVE EXPERIENCED THIS PROBLEM. I AM REQUESTING THAT A RECALL BE PLACED FOR THESE MODULES. *TR

2002 YUKON. STEERING PART ISSUE. REPLACED TWICE IN TWO YEARS, LUBRICATED PRIOR TO THAT. BEEN IN SHOP FOR SAME THING 4 TIMES OR MORE FOR SAME ISSUE. WHEN MANUFACTURER CONTACTED ABOUT THIS AFTER THE FOURTH TIME IN THE SHOP FOR SAME ISSUE....STATED "IF STAYS FIXED FOR A YEAR, SERVICE DEPARTMENT DOING THEIR JOB AND NOT GM'S PROBLEM....NO PERMANENT RESOLUTION" MANUFACTURER REQ# 1-375628602. IF THIS PERSISTS, COULD CAUSE MAJOR ACCIDENT/INJURIES. *JB

I REALIZE THIS MAY NOT SEEM LIKE A SAFETY ISSUE; BUT BEAR WITH ME. WE HAVE A YUKON XL GMC 2002 MODEL. WE HAVE HAD THE CARPET REPLACED 3 TIMES!! THERE IS A DEFECT IN THE CARPET ON THIS MODEL. IT SHEDS, NOT A LITTLE HAND FULLS. IF YOU ROLL THE WINDOW DOWN "FUZZ" FROM THE CARPET IS FLYING EVERYWHERE. AFTER DISCUSSION WITH ANNE MARIE EXECUTIVE FOR GMC, I LEARNED THAT 2002, 2003, AND SOON TO BE 2004 CARPET IS LIKE THIS. THIS WILL CAUSE AN ACCIDENT COUNT ON IT. YOU ARE SO CAUGHT OFF GUARD AT THE FLYING CARPET. PLEASE JUST LOOK INTO THIS MATTER. I RECEIVED AN ANSWER OF THAT IS JUST THE WAY IT IS AND WE DON'T HAVE TO CHANGE IT.
