ENGINE LIGHT AND REDUCE ENGINE POWER AND START LOOSING SPEED. AFTER TURNED OFF FOR A FEW MINUTES WORK FINE. THIS YEAR IN AN HOUR RIDE HAVE TO STOP AT LEAST 20 TIMES. COMPUTER CODES STATED NEED TO CHANGE THROTTLE BODY. LAST WEEK I CHANGE IT AND AGAIN THE SAME PROBLEM. *TR

KEY IGNITION SWITCH IS LOOSE AND CAR WILL SHUT OFF WHILE OPERATING, KEY CAN BE PULLED OUT OF IGNITION WHILE RUNNING. IF VEHICLE SHUTS OFF WHILE OPERATING THEN YOU LOOSE CONTROL OF BRAKES, STEERING, AND ELECTRICAL SYSTEMS. GM IS DENYING THERE IS A PROBLEM. MY VEHICLE IS PROOF THAT THE PROBLEM EXISTS AND THE CHEVY AVALANCHE 2003 HAS A PROBLEM. *TR

I BELIEVE THE SAME PROBLEM WITH THE GM KEY/IGNITION SWITCH IS MORE COMMON THEN WHAT IS BEING REPORTED. THE AVALANCHE 2003 HAS HAD THE SAME LOOSE IGNITION SWITCH FOR YEARS. OUR KEY SYSTEM HAS TO BE JIGGLED AND FORCED TO THE START POSITION 80 PERCENT OF THE TIME. THE IGNITION SWITCH WILL ALSO MOVE THE OFF POSITION WHILE THE VEHICLE IS MOVING AND THE KEY WILL FALL OUT.

THE VEHICLE WAS STOPPED AT A 2-WAY STOP. UPON TURNING RIGHT, MY FOOT WENT FROM THE BRAKE TO THE GAS PEDAL AND GOT HOOKED ON A PIECE OF METAL EXTENDING FROM THE ARM OF THE ACCELERATOR. THIS CAUSED MY FOOT TO BE TRAPPED BELOW THE BRAKE PEDAL BUT ATTACHED TO THE GAS PEDAL. THE VEHICLE SPUN BACK AND FORTH WHILE TRYING TO GET MY FOOT OFF THE ACCELERATOR. I HIT A TRUCK COMING FROM THE OPPOSITE DIRECTION FROM WHICH I WAS TURNING PINNING IT TO THE GUARD RAIL. ALTHOUGH BOTH TRUCKS HAD STOPPED, THE TIRES ON MY TRUCK WERE STILL SPINNING BECAUSE MY FOOT WAS STILL HOOKED ON THE ACCELERATOR AND WEDGE BELOW THE BRAKE PEDAL. ONLY AFTER I TURNED THE KEY OFF COULD I PUT THE TRUCK IN PARK. IN ORDER TO GET OUT OF MY TRUCK I HAD TO UNLACE MY SHOE AND PULL MY FOOT OUT, THEN PRY IT OFF THE SIDE OF THE ACCELERATOR, LEAVING A HOLE IN THE SIDE OF MY SHOE. *TR

TL*THE CONTACT OWNS A 2003 CHEVROLET AVALANCHE 1500. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 65 MPH, THE SPEEDOMETER SEEMED TO BE DEFECTIVE. THE SPEEDOMETER FAILED PERIODICALLY WHICH CAUSED THE CRUISE CONTROL TO FAIL. THE VEHICLE HAD NOT BEEN INSPECTED BUT THE DEALER, WHEN CALLED, STATED THAT THE CONTACT WOULD BE RESPONSIBLE FOR ANY REPAIR EXPENSES. THE CONTACT CALLED THE MANUFACTURER WHO OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 130,000. THE CURRENT MILEAGE WAS APPROXIMATELY 155,000.

LAST YEAR IN MY 2003 AVALANCHE I WAS CRUISING ON AN INTERSTATE HIGHWAY AND I NOTICED MY SPEEDOMETER START TO MOVE BACKWARDS UNTIL IT READ ABOUT 25 MPH, HOWEVER, I WASN'T SLOWING DOWN. IT WAS VERY CONCERNING TO ME, SO I FIRST PULLED OVER TO LOOK UNDER THE HOOD, BUT I FOUND NOTHING. CURRENTLY THE SPEEDO DOES NOT OPERATE AT ALL, BUT I WENT THROUGH A FEW MONTHS WHERE IT WOULD START TO WORK PARTIALLY AFTER ABOUT AN HOUR OF DRIVING. THIS IS UNACCEPTABLE THAT SO MANY PEOPLE ARE EXPERIENCING THE EXACT SAME PROBLEM. OBVIOUSLY THIS PART WAS SUPPLIED BY GM IN LARGE NUMBERS OF FAULTY PARTS, AND REGARDLESS OF MILEAGE I BELIEVE I SHOULD BE COMPENSATED TO FIX THE SPEEDO. I HAD NO MAINTENANCE CONTROL OVER THE LIFE OF THE ELECTRONICS, AND IT'S NOT LIKE IF I HAD CHANGED THE OIL MORE REGULARLY I WOULDN'T HAVE HAD THIS PROBLEM. CHEVY'S ARE TOO GOOD OF TRUCKS TO HAVE THIS KIND OF PROBLEM ON SO MANY OF THEIR TRUCKS. I'M SERIOUSLY CONSIDERING MOVING BACK TO A FORD TRUCK BECAUSE I OWNED A '95 BRONCO THAT HAD 248K MILES AND NEVER HAD AN ELECTRONIC PROBLEM. *TR

I HAVE A 2003 CHEVROLET AVALANCHE THAT WAS PURCHASED NEW IN JANUARY 2003. IT CURRENTLY HAS 110,000 MILES ON IT, BUT SINCE ABOUT 40,000 MILES THE SPEEDOMETER HAS BEEN ACTING UP. IT IS REAL JERKY WHEN MOVING AND STICKS ON SPEEDS. CURRENTLY, IT IS PARKED AND ON 100. YOU NEVER KNOW WHEN IT WILL WORK CORRECTLY - SOMETIMES IT DOES. *AK

TL* - THE CONTACT CALLED REGARDING THE 2003 CHEVROLET AVALANCHE. THE CONTACT STATED THAT THE SPEEDOMETER WAS FAULTY. HE WAS TRAVELING AT 70 MPH AND WITHOUT ACCELERATING THE VEHICLE THE SPEEDOMETER WENT TO 120 MPH. THE CONTACT STATED THAT WHEN HE TURNED THE VEHICLE OFF THE SPEEDOMETER REMAINED AT 40 MPH. THE CONTACT TOOK THE VEHICLE TO A CHEVROLET DEALER , AND THE VEHICLE WAS DIAGNOSED AS NEEDING A NEW SPEEDOMETER CLUSTER. THE FAILURE MILEAGE WAS 40000 AND THE CURRENT MILEAGE WAS 45000.*AK

Mileage: 40,000

STARTED TO NOTICE A TWITCH IN THE SPEEDOMETER READING ABOUT A MONTH AGO. PROGRESSIVELY BECAME WORSE TO THE POINT THAT IT READS FASTER AND FASTER AND DOES NOT GO BACK DOWN TO ZERO. NOW IT IS PRESENTLY STUCK PAST 140 MPH. *JB

I HAVE BEEN HAVING ERRONEOUS SPEEDOMETER PROBLEMS WITH MY VEHICLE FOR ABOUT 2 YEARS NOW. THE SPEEDOMETER HAS A MIND OF ITS OWN. IT WILL BE WORKING FINE, AND THEN GO ERRONEOUS. IT WILL GET STUCK AT 60 MPH OR HIGHER. SOMETIMES IT IS EVEN 120! THIS SEEMS TO OCCUR MORE WHEN IT IS RAINING. I HAVE FOUND THAT IF I REMOVE THE NEGATIVE TERMINAL FROM THE BATTERY AND RESET THE COMPUTER, IT BEGINS WORKING AGAIN. I NEVER KNOW HOW FAST I AM GOING WHICH CAN BE VERY DANGEROUS. *JB
