MY SPEEDOMETER QUIT WORKING. THIS IS A KNOWN DEFECT WITH THE 2004 AVALANCHE. OTHER THINGS THAT HAVE WENT WRONG ARE THE GAS GAUGE DOESN'T WORK. THIS TO ME IS A BIG SAFETY ISSUE. YOU CANT TELL HOW FAST YOU ARE GOING. *TR

THE LOCAL DEALER, RYAN CHEVROLET, INFORMED ME THAT GM WOULD HAVE FIXED IT PRIOR TO 72,000 MILES. I FOUND THIS OUT AFTER 85,000 MILES. *TR

NOW IT STICKS AT VARIOUS SPEEDS AND STAYS THAT WAY. IT HAS GONE PAST 120 MPH. GM REALLY NEEDS TO LOOK AT THIS PROBLEM AND FIX IT. THIS IS A SERIOUS SAFETY ISSUE.

SPEEDOMETER STOPS WORKING, STICKS OR READS TOO LOW OR TOO HIGH. VERY DANGEROUS. *TR
ON CERTAIN TRUCKS EQUIPPED WITH AN 8.1L V8 (RPO L8-VIN G) ENGINE HAVE A CONDITION IN WHICH THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP MAY FRACTURE RESULTING IN INADEQUATE RETENTION OF THE DAMPER.
Consequence & remedy
Consequence: IF THE DAMPER COMES LOOSE, A FUEL LEAK MAY RESULT. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 31, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC TRUCKS AT 1-866-996-9463.
ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION. APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.
Consequence & remedy
Consequence: A LAP PORTION OF THE SEAT BELT ROUTING THAT IS NOT LOW AND SNUG ON THE HIPS CAN ALLOW THE LAP BELT TO RIDE UP ON AN OCCUPANT'S ABDOMEN INSTEAD OF FITTING LOW AROUND THEIR HIPBONES, AND THEREFORE, CAN EXPOSE THEM TO MORE RISK OF ABDOMINAL AND INTERNAL ORGAN INJURY.
Remedy: DEALERS WILL CUT OPEN THE GUIDE LOOP, REMOVE A PORTION OF THE LOOP, AND THEN THE REMAINING TWO SIDES SHOULD BE FOLDED OVER AND SECURED WITH A RETAINER FREE OF CHARGE. THE RECALL BEGAN ON JULY 21, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR HUMMER AT 1-800-732-5493.
CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
Consequence & remedy
Consequence: IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT AND A CRASH MAY OCCUR WITHOUT PRIOR WARNING.
Remedy: DEALERS WILL TEST THE HYDRO-BOOST ASSEMBLY FOR FUNCTIONAL OPERATION OF THE TWO-FUNCTION VALVE. IF THE HYDRO-BOOST ASSEMBLY FAILS THE TEST, DEALERS WILL REPLACE THE ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON MARCH 23, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC TRUCKS AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493.
ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE GALVANIZED STEEL TAILGATE SUPPORT CABLES THAT RETAIN THE TAILGATE IN THE FULL OPEN (HORIZONTAL) POSITION MAY CORRODE, WEAKEN, AND EVENTUALLY FRACTURE. IF BOTH CABLES FRACTURED, THE TAILGATE WOULD SUDDENLY DROP AND STRIKE THE TOP SURFACE OF THE REAR BUMPER.
Consequence & remedy
Consequence: ANYONE SITTING OR STANDING ON THE HORIZONTAL SURFACE OF THE TAILGATE WHEN BOTH CABLES FRACTURED COULD BE INJURED BY FALLING FROM THE TAILGATE. ON VEHICLES THAT HAVE HAD THE BUMPER REMOVED, THE TAILGATE MAY DROP EVEN LOWER. ADDITIONALLY, IF THERE IS CARGO ON THE TAILGATE THE CARGO MAY FALL OFF IF THE SUPPORT CABLES FRACTURE.
Remedy: DEALERS WILL REPLACE THE CABLES. INTERIM OWNER NOTIFICATION BEGAN ON APRIL 7, 20004. THE RECALL BEGAN ON SEPTEMBER 24, 2004, WHEN REPLACEMENT PARTS WERE AVAILABLE, AND WILL CONTINUE THROUGH OCTOBER 29, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463, OR VISIT WWW.MYGMLINK.COM, AND ENTER YOUR VEHICLE IDENTIFICATION NUMBER.
CERTAIN SPORT UTILITY VEHICLES, PICKUP TRUCKS, AND PASSENGER VANS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, ?PASSENGER CAR BRAKE SYSTEMS.? SOME OF THESE VEHICLES WERE PRODUCED WITH AN OUT-OF-SPECIFICATION BRAKE HYDRO-BOOST HOUSING RELIEF VALVE BORE.
Consequence & remedy
Consequence: CONSEQUENTLY, THE VALVE O-RING SEAL MAY FRACTURE. STEERING EFFORTS MAY BE SLIGHTLY INCREASED WHILE BRAKING OR PARKING. UNDER CERTAIN DRIVING CONDITIONS, A FRACTURED SEAL MAY REQUIRE A SLIGHT INCREASE IN THE APPLIED BRAKE PEDAL EFFORT TO ACHIEVE THE SAME VEHICLE DECELERATION RATE AS PRIOR TO THE SEAT FRACTURE.
Remedy: DEALERS ARE TO REPLACE THE HYDRO-BOOST RELIEF VALVE. THE RECALL BEGAN ON JUNE 18, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339; CHEVROLET AT 1-800-630-2438; GMC AT 1-866-996-9463; OR HUMMER AT 1-866-486-6376.
