I HAVE HAD SEVERAL ISSUES WITH MY 2003 CHEVORLET AVALANCHE Z71 ONLY 62,000 MILES. MY PROBLEMS STARTED AROUND 8,000 MILES WITH THE REAR BRAKES GOING BAD. I HAVE REPLACED THE FRONT AND REAR BRAKES FOUR (4) TIMES SINCE I HAVE OWNED IT. THE ABS SPEED SENSORS HAVE BEEN REPLACED ONCE AND NEED REPLACED AGAIN. THE SPEEDOMETER IS STUCK AT 120 MPH, THE U JOINTS HAVE BEEN REPLACED AND NOW THE TRANSMISSION HAS GONE OUT. I FEEL THAT CHEVORLET SHOULD FIX THESE PROBLEMS UNDER A WARRANTY/RECALL. *TR

I WAS DRIVING DOWN HWY 316 AND BEGAN APPROACHING A RED LIGHT. WHEN I ATTEMPTED TO BEGIN STOPPING FOR THE RED LIGHT, MY BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR AND THE BRAKES DIDN'T SEEM TO BE WORKING. LUCKILY I WAS ABLE TO SAFELY PULL OFF THE RIGHT SIDE OF THE ROAD AND WAS ABLE TO AVOID HITTING ANY OTHER VEHICLES OR OBJECTS. I THEN PULLED INTO AN EMPTY PARKING LOT ABOUT 50 FEET AWAY. WHEN I GOT OUT OF MY VEHICLE AND STARTING LOOKING AROUND I COULD SEE FLUID DRIPPING ON THE GROUND NEXT TO THE DRIVER SIDE FRONT WHEEL. I THEN WAS ABLE TO FIND THAT THE FLUID WAS BRAKE FLUID AND IT WAS COMING FROM A PINHOLE SIZED LEAK IN THE STAINLESS STEEL BRAKE LINE COMING FROM THE MASTER CYLINDER AND GOING TO THE ABS SYSTEM. AFTER CLOSER INSPECTION I HAVE DISCOVERED THAT ALL MY STEEL BRAKE LINES ARE SEVERELY RUSTED. THERE WERE NO WARNING SIGNS, LIGHTS, BONGS, OR BEEPS UNTIL AFTER MY BRAKES FAILED.MY BRAKES WOULD BARELY WORK,THE PEDAL WOULD GO TO THE FLOOR AND I WOULD ONLY BE ABLE TO SLOW MY VEHICLE DOWN ENOUGH TO SHIFT INTO NEUTRAL AND THEN SHIFT INTO PARK TO COMPLETELY STOP. I CONSIDER MYSELF AND MY FAMILY EXTREMELY FORTUNATE THAT WE WERE ABLE TO AVOID A CRASH AND WERE NOT HARMED OR DIDN'T HARM ANYONE ELSE. AFTER THIS OCCURRED I STARTING DOING RESEARCH ON THE INTERNET AND DISCOVERED THAT THIS HAS BECOME A MAJOR ISSUE WITH CHEVROLET VEHICLES IN THE SALT BED STATES. I LIVE IN GEORGIA, BUT MY CHEVY AVALANCHE IS FROM A SALT BED STATE AND WAS ONLY RECENTLY BROUGHT TO GA. *TR

THIS IS THE SECOND COMPLAINT THAT I WILL BE GIVING IN REGARDS TO THE BRAKE LINE ON MY CHEVY AVALANCHE AS PER COMPLAINT NUMBER: 10430307. I TOOK MY TRUCK TO A GMC/CHEVY DEALERSHIP TO HAVE THE BRAKE LINE REPLACE WHICH COST 600.00. NOT EVEN A WEEK AFTER BRINGING THE TRUCK HOME, I START UP THE TRUCK, PUT IT INTO REVERSE AND AS I START MOVING BACKWARDS AND APPLY THE BRAKES, THE BRAKE PEDAL GOES TO THE FLOOR AND A LOUD POP IS HEARD. UPON INSPECTION, BRAKE FLUID WAS POURING OUT FROM UNDER THE DRIVER SIDE AGAIN AND NOW I WILL HAVE TO RETURN IN THE TRUCK TO THE DEALERSHIP. GMC DID NOT OFFER ANY HELP TO REPAIR/REPLACE THE BRAKE LINES THE LAST TIME AND IT IS UNKNOWN AS OF NOW IF THEY WILL THIS TIME. IT WAS NOT EVEN ONE WEEK AND THE BRAKE LINES GAVE OUT YET AGAIN EVEN AFTER JUST BEING FIXED. SOMEONE MUST HOLD GM ACCOUNTABLE FOR THIS BEFORE MORE PEOPLE GET HURT OR WORSE DUE TO FAULTY MATERIALS USED ON THESE VEHICLES. *TR

OCTOBER 14, 2011: MY FAMILY AND I WERE BACKING OUT FROM OUR HOME WHEN WE LOST PRESSURE IN THE BRAKE PEDAL. UPON VISUAL INSPECTION UNDER THE DRIVERSIDE DOOR, BRAKE FLUID WAS FLOWING FREELY ONTO THE ROAD. A CLOSER LOOK REVEALED THAT THE BRAKE LINES WERE SEVERELY CORRODED AND THAT THEY HAD RUPTURED WHEN PRESSURE WAS APPLIED TO THE BRAKES. AS I PULLED MY TRUCK BACK INTO THE DRIVEWAY, IT TOOK 10-15 FT JUST TO BRING THE TRUCK TO A COMPLETE STOP USING THE EMERGENCY BRAKE AND I DID NOT EVEN GET UP TO 3 MPH. I AM VERY CONCERNED AS TO WHAT COULD OF HAPPENED TO MY FAMILY AND I WERE TRAVELING DOWN THE ROAD AT 45 MPH OR FASTER AND WENT TO BRAKE AND THE LINE RUPTURED NOT TO MENTION ANYONE ELSE I WOULD OF CRASHED INTO. I DID SOME RESEARCH ONLINE AND HAVE DISCOVERED THAT THERE IS A CURRENT INVESTIGATION (NHTSA ACTION NUMBER :EA11001) THAT IS PENDING FINAL RESULTS. PLEASE ADD MY OWN EXPERIENCE TO YOUR GROWING LIST OF ISSUES WITH GM'S MANUFACTURING/INSTALLATION OF BRAKE LINE. IT IS APPARENT THAT THIS ISSUE IS NOT ONE THAT HAS AFFECTED A SMALL PERCENTAGE OF BUYERS. I STRONGLY ASK THAT SOMEONE PLEASE FIGURE OUT THE CORRECTIVE ACTION FOR GM TO TAKE THAT DOES NOT NEGATIVELY AFFECT THE CUSTOMERS BOTH ETHICALLY AND FINANCIALLY. *TR

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.
