I WAS DRIVING MY DAUGHTER HOME FROM TUTORING WHEN I REALIZED THE SPEEDOMETER DOES NOT WORK PROPERLY. I HAPPENED TO BE ON THE INTERSTATE AT THE TIME SO I KEPT UP WITH THE OTHER CARS, BUT GOING DOWN THE STREETS TO OUR HOUSE IN THE DARK MADE ME UNCOMFORTABLE. SOMETIMES IT STICKS AT ZERO AND OTHER TIMES IT MAXS OUT AT 120 MPH. THE DEALER I CALLED SAID THIS WAS A COMMON PROBLEM AND WOULD COST ABOUT $600+ TO FIX AND ALSO IT WOULD TAKE A FEW DAYS. *NM

THE WINDOW HINGE ON THE REAR WINDOW OF MY 2003 GMC YUKON BECAME DISCONNECTED FROM THE WINDOW. THIS HAS BEEN USED VERY RARELY, AND THE VEHICLE IS ALWAYS GARAGED. IT SEEMS LIKE A MANUFACTURER DEFECT, OR DESIGN FLAW...NOT SOMETHING THAT FAILED BECAUSE OF NORMAL WEAR AND TEAR. WITHOUT REPAIR, THIS COULD LEAD TO WINDOW SEPARATION AND HARM TO OTHER VEHICLES FOLLOWING ME ON THE HIGHWAY. *JB

MY 2003 GMC YUKON DENALI HAD JUST OVER 63,000 MILES ON THE ODOMETER. I AM THE ORIGINAL OWNER OF THE VEHICLE. THE MAJORITY OF THE DRIVING HAS BEEN ON PAVED ROADS/HIGHWAYS. THE HUB ASSEMBLIES (BOTH SIDES) BEGAN MAKING A NOISE IN MARCH OF 2006. SINCE THE VEHICLE WAS OUT OF WARRANTY, I TOOK IT TO A LOCAL CERTIFIED AUTO REPAIR FACILITY AND HAD THEM LOOK AT IT. THEY TOLD ME THAT BOTH FRONT WHEEL HUB ASSEMBLIES WERE IN IMMEDIATE NEED OF REPLACEMENT AND THAT THERE WAS A DANGER IN DRIVING THE VEHICLE. I HAD THE WORK DONE ON MARCH 22, 2006. TO THE BEST OF MY KNOWLEDGE THE FAILED PARTS ARE STILL AVAILABLE. I CONTACTED THE BBB WHO, IN TURN, REFERRED ME TO THE GMC CUSTOMER SERVICE OFFICE. AFTER CONTACTING THESE PEOPLE THEY FILE A REPORT #1-408898915. THEY INDICATED TO ME THAT GMC WOULD DO NOTHING FOR ME DUE TO THE FACTS THAT THE VEHICLE WAS OUT OF WARRANTY AND THAT I HAD NOT USED A GMC DEALER FOR THE REPAIR WORK. THE REPAIRS WERE #613.59. THE DEALER WOULD HAVE CHARGED ME APPROXIMATELY $1,000 FOR THIS SAME WORK. THEY DID GIVE ME THE ADDRESS OF THE GMC DIVISIONAL OFFICE IN MICHIGAN AND SUGGESTED THAT I CONTACT THEM TO SEE IF THEY WILL DO ANYTHING FOR ME. I WILL DO THIS, BUT I HAVE NOT DONE THIS YET AS I DO NOT ANTICIPATE A POSITIVE RESULT FROM MY EFFORTS. I FEEL THAT THIS IS A DEFECT OF THE PARTS AND/OR VEHICLE. ESPECIALLY SINCE BOTH THE BRAKES AND THE TIRES OUT LASTED THE WHEEL ASSEMBLIES. THERE SHOULD BE AN "IMPLIED WARRANTY" THAT MAJOR COMPONENTS LIKE THESE HAVE A LIFE EXPECTANCY THAT EXCEEDS THE WRITTEN WARRANTY. *NM

I HAD JUST GOTTEN OFF THE INTERSTATE FROM A 4 HOUR DRIVE AND HEARD A AWFUL GRINDING NOISE COMING FROM THE FRONT PASSENGER SIDE OF THE VEHICLE. IT SOUNDED LIKE "METAL AGAINST METAL".

I HAD JUST GOTTEN OFF THE INTERSTATE FROM A 4 HOUR DRIVE AND HEARD A AWFUL GRINDING NOISE COMING FROM THE FRONT PASSENGER SIDE OF THE VEHICLE. IT SOUNDED LIKE "METAL AGAINST METAL". AT FIRST I THOUGHT IT WAS A BRAKE PAD, BUT THE PADS APPEARED TO BE FINE. I PARKED IT THAT NIGHT AND ON SUNDAY MORNING (6/6/2005) DROVE IT TO THE DEALERSHIP AND ASKED THEM TO CALL IN THE MORNING. THE DEALERSHIP CALLED ME MONDAY MORNING AND SAID THAT THE FRONT WHEEL BEARING HAD GONE BAD. IN MY DISCUSSION WITH THE SERVICE MANAGER, HE INDICATED THAT THIS IS A COMMON PROBLEM WITH THE SURBURBANS, ENVOY'S AND YUKONS. MY CONCERN IS THAT HOW MUCH LONGER WOULD I DRIVEN BEFORE THE BEARING TOTALLY BUNED UP AND CAUSED THE LOSS OF STEERING? I HAD THE WHEEL BEARING ASSEMBLY REPLACED AT A $494.70 EXPENSE TO ME AND IT IS CURRENTLY DRIVING FINE. THE VEHICLE HAD 46,369 MILES ON IT AT THE TIME OF FAILURE. *NM

WHEN THE VEHICLE'S IGNITION IS IN THE ACCESSORY POSITION THE TRANSMISSION CAN BE SHIFTED INTO REVERSE, NEUTRAL, DRIVE, ETC. WITHOUT THE BRAKE PEDAL BEING PRESSED. MY 3 YEAR OLD WAS SITTING IN MY LAP IN THE DRIVERS SEAT IN A PARKING LOT LISTENING TO THE RADIO IN ACCESSORY MODE HE PULLED THE GEAR SELECTOR DOWN INTO NEUTRAL AND THE CAR BEGAN TO ROLL. THINKING THAT THIS WAS NOT POSSIBLE, I TOOK THE VEHICLE INTO THE DEALERSHIP. THEIR REPLY, "OH THAT'S WEIRD, I DIDN'T KNOW IT WOULD DO THAT". NO FIX, JUST, "WE WILL LOOK INTO IT". *JB
