THE LETTER STATED THAT THE MANUFACTURER EXTENDED THE WARRANTY TO SEVEN YEARS FROM THE DATE THAT THE VEHICLE WAS IN SERVICE OR 70,000 MILES. THE CONTACT EXCEEDED THE EXTENDED WARRANTY AND THE DEALER WILL NOT REPAIR THE INSTRUMENT CLUSTER UNDER THE WARRANTY; HOWEVER, THE MANUFACTURER SHOULD BE RESPONSIBLE FOR THE REPAIRS SINCE THIS WAS A KNOWN SAFETY ISSUE. THE FAILURE MILEAGE WAS 55,000.

NO ACCIDENT YET. SMELLED GAS SO I LOOKED UNDER 2003 TAHOE FOR LEAKS AND NOTICED FILLER NECK PLUS FUEL LINES ALONG WITH BRAKE LINES WITH EXTREME RUST. I UNDERSTAND RUST FORMS ON ALL METALS. BUT THIS IS SOMETHING YOU SHOULD FIND ON TWENTY YEAR OR OLDER VEHICLES. I AM A LICENSED APR. AND RUN A QUALITY SHOP AND HAVE WORK ON VEHICLES FOR A LIVING FOR OVER THIRTY YEARS AND ONLY SEE THIS ON SUBSTANDARD OR LOW GRADE MATERIALS. SO WHY DO THESE LINES HAVE THIS PROBLEM? THIS IS A SAFETY ISSUE THAT REALLY SHOULD BE ADDRESSED. I'VE SEEN OTHER MANUFACTURERS RECALL MUCH LESS PROBLEMS WHY NOT THIS. IF YOU PRICE OUT THESE PIECES FOR REPLACEMENT YOU OR YOUR COSTUMER BETTER BE SITTING DOWN. PARTS ARE NORMALLY IN STOCK. WE ALL KNOW THEY ONLY STOCK WHAT'S SELLS REGULARLY.

405V163000 · 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.

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.

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.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings
On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues: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.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t
