I HAVE A 2003 CHEVY AVALANCHE THAT I BOUGHT NEW. IN OCTOBER 2007 MY MECHANIC REPLACED ALL 4 ROTORS AND PADS ON THE BRAKES. HE SAID THE BRAKES HAD RUSTED OUT FROM THE BACKSIDE.

I HAVE A 2003 CHEVY AVALANCHE THAT I BOUGHT NEW. IN OCTOBER 2007 MY MECHANIC REPLACED ALL 4 ROTORS AND PADS ON THE BRAKES. HE SAID THE BRAKES HAD RUSTED OUT FROM THE BACKSIDE. AT THAT TIME I PAID $390, AND THE REST WAS COVERED BY WARRANTY. ON OCTOBER 16, 2010, I WAS DRIVING FROM THE PHILADELPHIA AIRPORT TO MY HOME IN WEST CHESTER, PA. SHORTLY AFTER LEAVING THE AIRPORT, I SUDDENLY LOST ALL BRAKING POWER. THE BRAKES WERE COMPLETELY GONE. WHEN I PRESSED THE BRAKE PEDAL, NOTHING HAPPENED. I DROVE FOR MORE THAN 20 MILES THIS WAY, TO MY MECHANIC IN WEST CHESTER, ON SEVERAL ROADS WITH HEAVY TRAFFIC AND MANY STOP LIGHTS. I DID THIS BY SHIFTING GEARS AND BY TURNING THE ENGINE OFF AND ON. MY MECHANIC HAD TO FABRICATE SOME PARTS TO REPLACE THE BRAKE LINES, SINCE THESE PARTS ARE NO LONGER MADE BY GM. HE COMPLETELY REPLACED BOTH BRAKES. I PAID $394. I HAVE LEARNED ONLINE THAT SOME 110 OWNERS OF CERTAIN GM TRUCKS AND SUVS, INCLUDING THE MODEL I OWN, HAVE REPORTED THEIR VEHICLES TO THE NHTSA FOR BRAKE DEFECTS, AND THAT THERE IS AN ONGOING INVESTIGATION THAT BEGAN IN SPRING 2010. I WANT TO ADD MY COMPLAINT TO THOSE OTHERS. I THINK GM DID A SHODDY JOB MANUFACTURING THE BRAKES FOR MY 2003 AVALANCHE. IF THERE IS ANY WAY TO GET COMPENSATION FOR THIS, I AM INTERESTED. BUT AT THE VERY LEAST, I WANT THE NHTSA TO KNOW THAT MY BRAKES COMPLETELY FAILED ON A MAJOR URBAN HIGHWAY, AND THAT I BELIEVE POOR MANUFACTURING MATERIALS WERE THE CAUSE. HOPEFULLY THE REPAIRS DONE BY MY MECHANIC WILL PREVENT A RECURRENCE. BUT FOR WHAT I PAID FOR MY AVALANCHE (ABOUT $35K), I DIDN'T EXPECT ROTTEN BRAKES. *TR

PICK A PROBLEM. PIN FROM TRANSMISSION GEARS WERE TOO SHORT FROM THE MANUFACTURER, CAUSING THE TRANSMISSION TO NOT SHIFT PROPERLY. THIS REPAIR WAS DONE AT 8000 MILES. 4 QUARTS. LOW ON OIL WITHIN MONTH OF CHANGING. NO LEAKS AND NO EXPLANATION FROM THE DEALER AS TO WHERE THE OIL WENT. A/C FUNCTIONED IMPROPERLY AFTER TRUCK SURGED AT TRAFFIC LIGHT. STILL NO EXPLANATION. REMOTE ENTRY WORKS WHEN IT WANTS TO. INTERIOR LIGHTS PULSE WHEN TRUCK IDILING. HEATER MOTOR FUNCTIONS ACCORDING TO SPEED OF VEHICLE, SLOW WHEN BRAKING AND SPEEDS UP WHEN ACCELERATING. DRIVERS POWER WINDOW STOPPED FUNCTIONING AND STARTED WORKING THE EVENING BEFORE TAKING IT TO THE DEALERSHIP FOR REPAIR. POPPING NOISE FROM EXHAUST JUST AFTER STARTING AND SHUTTING OFF. FROM INSIDE THE VEHICLE WHILE RUNNING I CONTINUOUSLY HEAR COOLING FLUIDS FLOWING. SOMETIMES THE HORN DOES NOT FUNCTION WHILE THE VEHICLE IS TURNED OFF. BRAKING HAS ALWAYS BEEN A PROBLEM FROM DAY ONE. ALWAYS FEELS AS THERE ISN'T ENOUGH BRAKE PRESSURE TO STOP IN A NORMAL DISTANCE. ALONG WITH THE REMOTE ENTRY NOT WORKING THE PERSONAL PRESETS FOR DRIVER 1 MOST OF THE TIME DO NOT OPERATE WITH THE REMOTE ENTRY. I HAVE TO SELECT DRIVER 1 FROM THE INTERIOR TO ENGAGE SETTINGS. BED PLASTICS ARE FADING. BUTTONS FOR RADIO ON THE STEERING WHEEL AND RADIO ARE FLAKING. *AK

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.
Mar 17, 2004
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.
Jan 27, 2003
ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, VEHICLES, DURING A 30 DEGREE LEFT ANGLE FRONTAL IMPACT OF SUFFICIENT SEVERITY, A TEAR COULD DEVELOP IN THE MID-FRAME CROSS MEMBER AT ITS ATTACHMENT TO THE LEFT FRAME RAIL. IF THE MID-FRAME CROSS MEMBER TEARS DURING FRONTAL IMPACT AND PRODUCES A SHARP EDGE, CONTACT OF THE SHARP EDGE WITH THE FUEL TANK COULD RESULT IN A PUNCTURE OF THE FUEL TANK AND POSSIBLE FUEL LEAKAGE.
Consequence & remedy
Consequence: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL INSTALL A FUEL TANK SHIELD. OWNER NOTIFICATION BEGAN FEBRUARY 20, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.
