I WAS TOWING A 17' BOAT AND CAME TO A STOP SIGN. I PRESSED THE BRAKE PEDAL AND IT WENT TO THE FLOOR. THE YUKON DID NOT SLOW AT ALL. FORTUNATELY, NO ONE WAS COMING AND I ROLLED THROUGH THE STOP SIGN, MADE A RIGHT TURN, AND WENT DOWN A STEEPER HILL. PUMPING THE BRAKES AS I WENT HAD NO EFFECT. THE DASH SHOWED A 'SERVICE BRAKE' MESSAGE. I APPLIED THE PARKING BRAKE AND DOWN-SHIFTED, WHICH SLOWED IT ENOUGH THAT I WAS ABLE TO SWING WIDE INTO THE OPPOSING TRAFFIC LANE AND BARELY MAKE THE TURN AT THE BOTTOM OF THE HILL. I PULLED OFF TO THE SIDE OF THE ROAD WITH THE RIGHT-WHEELS ON A SOFT SHOULDER BEFORE THE VEHICLE SLOWLY CAME TO A STOP. I REFILLED THE BRAKE RESERVOIR AND HAD MY WIFE PRESS THE BRAKE PEDAL. IT WENT TO THE FLOOR AS BRAKE FLUID SHOT ONTO THE HOT EXHAUST MANIFOLD, LEAKING FROM A RUSTED JOINT WHERE THE STEEL BRAKE LINE JOINED A FLEXIBLE, BRAIDED LINE UNDER THE HOOD. THE BRAKE LINES WERE HORRIBLY RUSTED, UNLIKE ANYTHING I HAD EVER SEEN IN MY 35+ YEARS OF DRIVING AND OWNING VEHICLES (INCLUDING 20 CARS AND LIGHT TRUCKS). THIS YUKON HAS SPENT ITS ENTIRE LIFE REGISTERED IN VIRGINIA AND HAS LESS THAN 80K MILES ON IT. I CAN'T IMAGINE WHAT THEY ARE LIKE IN NORTHERN STATES. LOOKING ONLINE, I DISCOVERED THAT THIS WAS A KNOWN PROBLEM THAT THE NHTSA HAD INVESTIGATED. WHY WAS I NOT WARNED? I COULD HAVE BEEN INJURED OR KILLED, AS COULD HAVE ANOTHER MOTORIST OR PEDESTRIAN! WHEN I CALLED MY LOCAL GMC DEALER (OURISMAN OF ALEXANDRIA, VA), THE SERVICE ADVISOR CLAIMED TO BE UNAWARE OF THE PROBLEM, THE GM SERVICE BULLETINS THAT HAD BEEN ISSUED ON IT, AND THE AVAILABILITY OF THE PRE-BENT LINES AS A DISCOUNTED KIT FROM GM. HE ESTIMATED A FOUR-FIGURE LABOR BILL TO DO THE WORK, SO I AM DOING AS MUCH OF IT AS I CAN MYSELF USING NICKEL-COPPER BRAKE LINE AND A FLARING TOOL. PEOPLE ARE GOING TO DIE FROM THIS IF THE NHTSA DOES NOT FORCE GM TO DO A RECALL.

WHEN I STOP THE VEHICLE, I CAN TURN OFF THE ENGINE. IF I CONTINUE TO TURN THE KEY 90% (BUT NOT ENOUGH TO START THE ENGINE), AND LET OFF, THE GAUGES WILL DROP UP TO 5%. AFTER 5 MINUTES OF RESETTING THE INSTRUMENTS, THE GAUGES WILL RESET. HOWEVER, THE NEXT TIME I DRIVE I MIGHT BE GOING THROUGH A SCHOOL ZONE AT 40 INSTEAD OF 25, BUT MY SPEEDOMETER SAYS 80.

THERE IS A RECALL #05068 THAT DESCRIBES EXACTLY WHAT HAPPENS WHILE DRIVING MY CAR. IT OCCURS EVERY TIME I DRIVE MY CAR, EVERY TIME I ACCELERATE AND BRAKE. (2003 GMC YUKON XL). HOWEVER, GMC CLAIMS MY CAR "ISN'T EFFECTED" AND THEY REFUSE TO FIX IT. MY ISSUES ARE 1. GETTING DANGEROUS, AS THE CAR BOGS AND WON'T ACCELERATE WITHOUT A PERIOD OF HESITATION AND THEN IT GIVES TOO MUCH ACCELERATION WHICH CAN BE BAD IF I'M ON A SLIPPERY SURFACE. ALSO, THERE IS A COMMON PROBLEM ON THESE VEHICLES WHICH IS ANOTHER PROBLEM I AM EXPERIENCING: 2. MY ABS KICKS IN RANDOMLY, EVEN IF THE PAVEMENT IS TOTALLY DRY AND CLEAR. APPARENTLY, THIS IS CAUSED BY A CORRODED MOUNTING SURFACE FOR THE FRONT WHEEL SPEED SENSORS. THE CORROSION BUILDS UP CAUSING EXCESSIVE GAP BETWEEN MOUNTING SURFACE AND WHEEL SPEED SENSOR WHICH CAUSES A LOSS OF WHEEL SPEED SENSOR SIGNAL. WHEN THE ABS MODULE SEES THE LOSS OF SIGNAL IT THINKS THE VEHICLE IS SLIDING OUT OF CONTROL SO IT WILL ACTIVATE THE TRACTION CONTROL OR ABS. DESCRIPTION FROM RECALL #05068: CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT... HAZARD:THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.

Official recalls

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 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.

CERTAIN PICKUP TRUCK, VAN, AND MINI VAN CONVERSIONS EQUIPPED WITH SOUTHERN COMFORT BUILT RUNNING BOARDS THAT CONTAIN CERTAIN COURTESY LIGHTS MANUFACTURED BY AMERICAN TECHNOLOGY COMPONENTS, INC. THESE UNITS CONTAIN A COURTESY LIGHT OR LIGHTS THAT MIGHT OVERHEAT WHEN THE WIRE HARNESS IS EXPOSED TO EXCESSIVE MOISTURE AND ROAD SALT.
Consequence & remedy
Consequence: THIS OVERHEATING CONDITION CAN CAUSE THE RUNNING BOARD TO MELT OR CAUSE A FIRE.
Remedy: DEALERS WILL REPLACE THE WIRING HARNESS ON THESE RUNNING BOARDS. OWNER NOTIFICATION BEGAN MARCH 7, 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 SOUTHERN COMFORT AT 1-800-745-6096.

CERTAIN SPORT UTILITY VEHICLES FAIL TO COMPLY WITH REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 214, "SIDE IMPACT PROTECTION." THESE VEHICLES ARE BUILT WITH FOUR WELDS ON THE REAR DOOR UPPER HINGE. ON SOME OF THESE VEHICLES, ONE OR TWO OF THE WELDS MAY NOT BE TO SPECIFICATION.
Consequence & remedy
Consequence: AS A RESULT, THE DOOR STRENGTH MAY BE DEGRADED DURING A SIDE IMPACT VEHICLE CRASH.
Remedy: DEALERS WILL INSPECT THE WELDS ON THE LEFT REAR DOOR UPPER HINGE. IF A WELD IS FOUND OUT-OF-SPECIFICATION, A BOLT WILL BE INSTALLED TO SECURE THE HINGE. OWNER NOTIFICATION BEGAN FEBRUARY 17, 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 CADILLAC AT 1-800-458-8006, 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.
