THE GAUGES IN THE INSTRUMENT CLUSTER STOP WORKING. FIRST THE SPEEDOMETER THEN THE TACHOMETER, AND NOW THE AMP METER. ON GOING PROBLEM. DEFINATELY A SAFETY CONCERN BUT NO ONE WANTS TO ADDRESS THE ISSUE. THE DEALER WANTS 600.00 DOLLARS TO REPAIR IR BUT DOES NOT GUARANTEE IT WILL BE THE FIX. OTHER VEHICALS OF THIS YEAR AND MODEL HAVE THE SAME ISSUE.

DAYS AFTER PURCHASING THE VEHICLE, THE CHECK ENGINE LIGHT CAME ON, THE VEHICLE POWERED DOWN TAKING THE SPEED FROM 35MPH OR ABOVE TO 5-10 MILES MPH WITH OUT WARNING. THIS CONTINUOUSLY HAPPENED AS YEARS PASSED AND GM CERTIFIED REPAIR SHOP NEVER FOUND WHAT'S WRONG. UNTIL ABOUT TWO YEARS AGO, I GOOGLED ISSUE AND FOUND ITS RELATED TO ACCELERATOR PEDAL AND WIRING FROM PEDAL THAT LEADS TO ENGINE THROTTLE CONTROL, I CHANGED THROTTLE CONTROL PLUG TO NEW AND REPLACED ACCELERATOR PEDAL WITH USED PART AND WORKED FINE FOR TWO YEARS BUT HAS NOW STARTED FAILING AGAIN. I AM AFRAID OF THIS ISSUE BECAUSE I COULD BE ON FREEWAY GOING 65 MPH AND IF THESE FAIL AS THEY HAVE AND ARE, I THEN SLOW DOWN TO 5-10 MPH IN A MATTER OF SECONDS AND COULD CAUSE A SERIOUS ACCIDENT. PLEASE HELP, THERE SHOULD BE A RECALL FOR THIS. *TR

TRACTION ACTIVE APPEARS ON DISPLAY - WHILE STOPPED AT A VERY DANGEROUS INTERSECTION, I PRESSED THE ACCELERATOR ONLY TO HAVE THE TRACTION ACTIVE LIGHT APPEAR ON THE DISPLAY AND THE VEHICLE WOULD NOT MOVE. I HAD TO LET OFF THE GAS AND THEN PRESS IT AGAIN IN ORDER FOR THE VEHICLE TO MOVE. THIS IS A MAJOR SAFETY CONCERN AS I AM UNABLE TO ACCELERATE AT AN APPROPRIATE SPEED IN ORDER TO AVOID AN ACCIDENT WHILE TAKING OFF FROM A STOP. *TR
THE SPEEDOMETER MALFUNCTIONED, LEAVING THE NEEDLE STUCK AT OVER 120 MPH. I NOW HAVE NO WAY OF KNOWING HOW FAST I AM TRAVELING, PUTTING MYSELF AND OTHERS AT RISK. *AK

Official recalls
205V163000 · Seat Belts:rear/other
Apr 22, 2005
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.
04V045000 · Service Brakes, Hydraulic
Feb 4, 2004
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.
