TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT WAS TOWING A BOAT AND DISCOVERED THERE WAS TRANSFER CASE OIL SPLATTERED ALL OVER THE BOAT. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR FACILITY WHERE HE WAS INFORMED THAT THERE WAS A HOLE IN THE TRANSFER CASE. A NEW TRANSFER CASE AND PUMP HOUSING WERE INSTALLED AT THE INDEPENDENT REPAIR FACILITY. THE FAILURE DID NOT RECUR. THE FAILURE AND CURRENT MILEAGES WERE 82,000.

MY HUSBAND WAS DRIVING OUR 2004 GMC SIERRA PICKUP ON HIGHWAY 101 IN THE CENTRAL COAST OF CALIFORNIA. WHILE DRIVING AT 65 MPH A BOLT FELL OUT OF THE STEERING COLUMN LEAVING HIM WITH ABSOLUTELY NO STEERING. HE CRASHED INTO A GUARDRAIL WHICH STOPPED THE VEHICLE. THE STEERING WHEEL SPINS AROUND LIKE A ROULETTE WHEEL AND CLEARLY IS NOT ATTACHED TO ANY PART OF THE STEERING COLUMN. THE RESPONDING TOW TRUCK DRIVER CLAIMED HE HAS NEVER SEEN A STEERING WHEEL LIKE THIS - NOT EVEN ON A VEHICLE THAT HAS BEEN WRECKED. *TR

THERE'S EITHER SOMETHING WRONG WITH THERE PARTS OR THEY WAY THEY BUILD THERE VEHICLES. I'VE OWNED SEVERAL GM VEHICLES AND THIS IS THE FIRST TIME I'VE HAVE MULTIPLE PROBLEMS.*TR

I RECEIVED A LETTER FROM GM STATING MY VEHICLES INSTRUMENT CLUSTER MAY GIVE FALSE READINGS. IF YOUR VEHICLE IS DOING THIS, TAKE THIS LETTER TO YOUR GM DEALER AND THEY WILL FIX THE PROBLEM IF IT'S NOT THEN YOU DON'T NEED TO. IT ALSO STATED THAT THE WARRANTY FOR THIS IS 70,000 MILES AND THEY WOULD NOT REPLACE THE CLUSTER IF IT WAS NOT GIVING FALSE READINGS. AT 93,721 MY FUEL GAUGE STARTED MALFUNCTIONING, AND AT 94,066 MILES MY SPEEDOMETER READING WAS OVER 120MPH, AND I WAS NOT EVEN MOVING. NOW WHEN I DRIVE THROUGH A SCHOOL ZONE OR NEIGHBORHOOD I HAVE NO IDEA HOW FAST I'M GOING. I DIDN'T EVEN HAVE 100,000 MILES ON THE VEHICLE WHEN THESE PROBLEMS STARTED HAPPENING. WHEN I TOOK MY VEHICLE IN TO GET IT FIXED UNDER THE WARRANTY THEY TOLD ME IT WAS OUT OF WARRANTY AND WOULD NOT COVER THE PARTS. SO MUCH FOR GMC PROFESSIONAL GRADE. THE LOGO THEY USE WHEN SELLING THERE VEHICLES ON TV. I HAVE SAVED PICTURES ON MY CELL PHONE SHOWING THE ACTUAL MILEAGE WHEN THESE FALSE READINGS OCCURRED. *TR

I OWN A 2004 GMC SIERRA 1500 THAT IS CURRENTLY BEING REPAIRED FOR CRACKS IN BOTH ENGINE HEADS. THE TRUCK HAS 90,000 MILES ON IT AND I HAVE KEPT UP ON ALL NECESSARY MAINTENANCE. THE PROBLEM BEGAN APPROX. 2 MONTHS AGO WHEN I NOTED A KNOCKING SOUND AFTER STARTING THE TRUCK COLD. THE KNOCKING WOULD DISSIPATE AFTER THE TRUCK WARMED UP. I WAS TOLD THE SOUND WAS CAUSED FROM DIRTY LIFTERS AND NOT TO BE CONCERNED AS LONG AS SOUND DISSIPATED AFTER IT WAS WARM. UPON HAVING MY OIL CHANGED 2 DAYS AGO, COOLANT WAS NOTED IN THE OIL. (HINTS THE KNOCKING) THE HEADS WERE PULLED AND BOTH WERE CRACKED AROUND WHERE THE HEADS BOLT TO THE BLOCK. IN TALKING TO THE MECHANIC, THE CAST THEY USED WHEN MAKING THE HEADS WAS BAD. APPARENTLY AROUND THE BOLT HOLES, THE ALUMINUM IS THIN. GMC HOWEVER ACCEPTED MILLIONS OF THESE AND ARE STILL USING THEM TODAY. THE REPAIR IS COSTING ME $3,400.00. *TR

WHILE DRIVING NOTICED THAT I WAS GOING FASTER THAN THE SPEEDOMETER SAID. FELT LIKE I WAS GOING AT LEAST 80 WHEN THE SPEEDOMETER SAID 45 MPH. KEPT WATCHING AND WHEN I CAME TO A STOP THE METER WOULD READ BELOW ZERO. TRIED RESTARTING THE TRUCK AND IT RESET TO ZERO BUT WHILE HOLDING A SET SPEED THE METER WOULD CONTINUOUSLY DROP. NEXT DAY WORKED FINE. 2 DAYS LATER I NOTICED THE METER DROP OFF AGAIN. WHEN I SHUT THE TRUCK OFF THIS TIME IT GOT STUCK AT 30MPH. DROVE FOR A LITTLE WHILE AND TRIED SHUTTING IT OFF AND STARTING IT AGAIN THIS TIME IT STAYED AT ZERO. IT TOLD THE WIFE NOT TO DRIVE IT UNTIL IT IS FIXED. I DON'T WANT HER IN THERE WITH MY CHILD IF THERE WAS A WRECK DUE TO NOT KNOWING WHAT SPEED THE TRUCK IS REALLY GOING. *TR
