Engine and Engine Cooling

Model year 2001

On certain pickup trucks equipped with an 8.1L V8 engine, the crankshaft position can operate intermittently or fail completely. If the sensor operates intermittently, the SEs light may illuminate and the vehicle may run rough. The engine may stall, and if so, may re-start immediately or after a cool down period.

Consequence:

If the sensor becomes completely inoperative, the engine will quit running and will not re-start. Either of these failures can increase the risk of a crash.

Remedy:

Dealers will replace the crankshaft position sensor free of charge. The recall began on December 18, 2007. Owners may contact Chevrolet at 1-800-630-2438 and GMC at 1-866-996-9463.

Air Bags › Frontal

Model year 2005

Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved. Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction.

Consequence:

If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.

Remedy:

Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, General Motors (GM) will repurchase these vehicles in accordance with the terms stated in GM's letter to owners. The recall began on November 6, 2006. Owners should contact GM at 1-877-477-1022 to begin the process of repurchasing their vehicle.

Wheels › Rim

Model year 2006

Certain sport utility vehicles and trucks fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 110, "tire selection and rims." These vehicles have an incomplete tire rim designation on the certification/tire label located on the driver's door edge. In addition, the label may also be missing the tire load rating on the label. Although this information is not required by the standard, if a tire of a lesser load rating is installed, the tire may not be able to sustain the loads encountered during use.

Consequence:

If a customer replaces a wheel and only relies on the rim size designation that is indicated on the label, a wheel that is of a different rim contour designation may be installed. It may be difficult or impossible to mount the tire on a wheel with the wrong contour. If the tire is mounted on the wheel with the wrong contour, the wheel and tire may not perform as intended, which could increase the risk of a crash.

Remedy:

A label that will correct the label originally installed will be mailed to consumers along with installation instructions. The customer will have the option for dealers to install the label. The recall begaon on November 7, 2006. Owners should contact Cadillac at 1-866-982-2239, Chevrolet at 1-800-630-2438, and GMC trucks at 1-866-996-9463.

Structure › Body › Tailgate › Hinge and Attachments

Model years 1999–2000

Certain pickup trucks have galvanized-braided-steel tailgate support cables used to support the tailgate in the full open (horizontal) position. Over time these cables can corrode and fracture when loads are applied to them.

Consequence:

If one cable fractures, the remaining cable may retain the tailgate in a horizontal position. If both cables fracture, the tailgate would drop and strike the top surface of the rear bumper. If anyone is sitting or standing on the horizontal surface of the tailgate when both cables fractured, they could fall and be injured. On vehicles without a bumper, the tailgate may drop to a lower position.

Remedy:

Dealers will replace the galvanized support cables with stainless steel support cables. In addition, dealers are to inspect the tailgate hinge and replace it, if necessary. The recall is expected to begin during April 2006. Owners may contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Equipment › Other › Labels

Model year 2006

Certain trucks and sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 110, "tire selection and rims." These vehicles were shipped with tire and loading information labels listing an inacccurate vehicle capacity weight.

Consequence:

A misprinted label could lead to improper vehicle loading specifications or tire inflation which could result in a tire failure, increasing the risk of a crash.

Remedy:

Owners will be provided with corrected labels and installation instructions. At the customer's option, a dealer can install the label for them. The recall began on March 31, 2006. Owners may contact Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Hummer at 1-800-732-5493, Pontiac at 1-800-620-7668, Saturn at 1-800-972-8876, or Isuzu at 1-800-255-6727.

Steering › Hydraulic Power Assist › Hose, Piping, and Connections

Model years 2005–2006

Certain passenger vehicles may have been built with a power steering hose that is not to specification. Under extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid.

Consequence:

If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine parts, an engine compartment fire could occur.

Remedy:

Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on October 14, 2005. Owners may contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Isuzu at 1-800-255-6727, or Hummer at 1-800-732-5493.

Service Brakes, Hydraulic › Antilock/Traction Control/Electronic Limited Slip

Model years 1999–2002

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, West Virginia, Wisconsin and the District of Columbia only.

Consequence:

This can cause increased stopping distances during low-speed brake applications, which could result in a crash.

Remedy:

Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The recall began September 22, 2005. Owners may contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Seat Belts › Rear/Other

Model years 2003–2005

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:

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.

Parking Brake

Model years 1999–2005

On certain pickup trucks equipped with manual transmissions and built with either PBR parking brake systems or TRW parking brake systems, the parking brake friction linings may wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.

Consequence:

If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.

Remedy:

Dealers will install a low-force spring clip retainer for vehicles equipped with a PBR parking brake system. On vehicles equipped with the TRW parking brake system, dealers will install a redesigned parking brake cable assembly. The recall began on July 29, 2005. Owners may contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Power Train › Manual Transmission › Shift Pattern Indicator

Model year 2005

Certain sport utility vehicles equipped with an automatic transmission, fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 102, "transmission shift lever sequence, starter interlock and transmission braking effect." Under certain vehicle starting conditions, the shift lever position indicator located in the instrument panel cluster may not illuminate. If the shift lever position indicator does not illuminate, the driver may not know which gear the vehicle is in.

Consequence:

The vehicle may move in an unintended direction resulting in possible injury to others outside of the vehicle.

Remedy:

Dealers will reprogram the instrument panel cluster free of charge. The recall began on February 14, 2005. Owners may contact Cadillac at 1-866-982-2339, Chevrolet at 1-800-630-2438, and GMC at 1-866-996-9463.

Service Brakes, Hydraulic

Model years 2004–2005

Certain trucks, sport utility vehicles, and vans equipped with bosch hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.

Consequence:

If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. The presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.

Remedy:

Dealers will test the hydro-boost assembly for functional operation of the two-function valve. If the hydro-boost assembly fails the test, dealers will replace the assembly free of charge. The recall began on March 23, 2005. Owners may contact Chevrolet at 1-800-630-2438, GMC trucks at 1-866-996-9463 and Hummer at 1-800-732-5493.

Seat Belts › Front › Anchorage

Model years 2003–2004

Certain extended and regular cab pickup trucks and cargo vans converted to compressed natural gas (CNG) fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 225, 'child restraint anchorage systems.' These vehicles have one seating position, the center rear seat, equipped with child restraint lower anchorages.

Consequence:

The standard requires child seat lower anchorages in two seating positions for vehicles with three rear seating positions. The standard cab and cargo van vehicles, which only have front seating positions, have an air bag off switch to disable the front passenger air bag and do not have child restraint lower anchorages in the passenger seat. The standard requires passenger seat child seat lower anchorages in vehicles with an air bag off switch. However, the standard does not require vehicles with only front seating positions to have lower anchorage provisions if the vehicle is not equipped with an air bag off switch.

Remedy:

To bring the standard cab and cargo van vehicles into compliance, dealers will inject epoxy into the air bag off switch to prevent air bag activation, relocate the switch behind the instrument panel and then install a cover over the resulting opening. The sun visor label and owner's manual will also be changed. The correction for the extended cab vehicle will consist of changing the front passenger seat to a seat that has child restraint lower anchorages. The recall began on September 9, 2004. Owners should contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Structure › Body › Tailgate › Hinge and Attachments

Model years 2000–2004

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:

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.

Service Brakes, Hydraulic

Model years 2003–2004

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:

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.

Fuel System, Other › Delivery

Model year 2002

Some 2WD and 4WD pickup trucks, converted to either dedicated or bi-fuel compressed natural gas (CNG) fuel usage, were assembled with a throttle cable that can contact and rub through the flexible pressurized fuel line creating a pinhole leak of natural gas to the atmosphere.

Consequence:

A strong odor of natural gas may be detected from inside the vehicle, possibly accompanied by a hissing noise. If the natural gas were accidentally ignited, serious injury could result.

Remedy:

Dealers will secure the throttle cable to eliminate the possibility of contact with the CNG fuel line. The CNG fuel line, throttle cable, and cruise control cable are also to be inspected and replaced if necessary. Owner notification began on December 11, 2003. Owners should contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Visibility › Windshield

Model year 2003

Certain pickup trucks fail to conform to Federal Motor Vehicle Safety Standard No. 212, "windshield mounting." Some of these vehicles lack a continuous urethane bonding bead between the body surface and the windshield.

Consequence:

In vehicles with this condition, the windshield may not be retained in accordance with the safety standard during a vehicle crash.

Remedy:

Dealers will remove, reseal, and reinstall the windshield. Owner notification began on January 28, 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.

Air Bags › Frontal › Sensor/Control Module-Inactive

Model year 2000

On certain pickup and utility trucks, some of these vehicles have an air bag sensing diagnostic module (SDM) which contains an anomaly that could result in the driver and passenger's air bag failing to deploy during certain frontal crashes.

Consequence:

In a vehicle crash, front seat occupants may receive more severe injuries.

Remedy:

Dealers will recalibrate the SDM on the affected vehicles. Owner notification began August 28, 2002. 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.

Service Brakes, Hydraulic › Foundation Components › Hoses, Lines/Piping, and Fittings

Model years 1999–2000

Vehicle description: light duty pickup trucks and sport utility vehicles. Some of these vehicles have a clearance condition between the front right-hand brake pipe and the body cross sill that could decrease to the point of allowing contact during the life of the vehicle. If contact occurs and the brake pipe becomes damaged, in half of the brake system there can be a loss of brake fluid and pressure. The brake warning lamp will be activated when the brake fluid level reaches the indicator limit.

Consequence:

During braking, the pedal will be lower than normal and stopping distances will be longer. If this occurs when stopping distance is limited, a crash could occur.

Remedy:

Dealers will inspect the front right-hand brake pipe for wear. If there are signs of wear, this section of the brake pipe will be replaced with a new designed brake pipe section. If there are not signs of wear on the brake pipe, the dealer will install a spacer clip to ensure sufficient clearance between the brake pipe and the body cross sill.

Service Brakes, Hydraulic › Antilock/Traction Control/Electronic Limited Slip

Model year 2000

Vehicle description: light duty pickup trucks equipped with 4-wheel disc brakes. Some of these vehicles have an antilock brake system (ABS) motor containing an out-of-specification spring clip. This clip could allow the motor bearing to become misaligned. If misalignment occurs, eventually the ABS would be non-functional.

Consequence:

The base brakes would remain fully functional, but the dynamic rear proportioning (DRP) system, which optimizes front to rear brake balance, would become inoperative.

Remedy:

Dealers will replace the brake pressure module valve assembly.

Steering › Gear Box (Other Than Rack and Pinion)

Model year 1999

Vehicle description: extended cab 4-wheel drive pickup trucks. Some of these vehicles have a lower than specified torque on all three of the steering gear to frame attachment bolts. The bolts can loosen over time allowing the steering gear to move. This loosening can result in some unresponsive steering feel and some noise to the driver.

Consequence:

If this condition is ignored, the steering gear to frame can wear and/or fatigue the attaching bolts to the point of breakage or the bolts backing out. If all the bolts break or back out, the steering gear would separate from the frame resulting in a loss of steering control.

Remedy:

Dealers will retorque the steering gear to frame bolts to proper specifications.

Visibility › Windshield Wiper/Washer

Model years 1995–1996

Vehicle description: light duty pickup trucks and sport utility vehicles, 2 and 4-wheel drive. Solder joints near the wiring harness connector can crack causing the windshield wipers to work intermittently.

Consequence:

This condition can result in inoperative wipers, reducing a driver's visibility, and increasing the risk of a vehicle crash.

Remedy:

Dealers will replace the wiper motor circuit board and cover.

Vehicle Speed Control

Model years 1995–1996

These vehicles were assembled with the throttle cable contacting the dash mat which could bind the throttle. This does not meet with the maximum return times required by Federal Motor Vehicle Safety Standard No. 124, "accelerator control systems."

Consequence:

Consequence of non-compliance: the engine speed may not return to idle increasing the potential for a vehicle accident.

Remedy:

Dealers will inspect for adequate throttle cable to dash mat clearance, and if there is insufficient clearance, cut out a portion of the dash mat to provide proper clearance.

Seat Belts › Front

Model year 1995

These vehicles were built with front seat belt systems with no energy management loops and may not meet the head injury criteria requirements of FMVSS No. 208, "occupant crash protection."

Consequence:

In the event of a vehicle crash, the occupants of these seats may not be properly restrained.

Remedy:

Dealers will replace the retractor portion of the seat belt assembly(s) with one having the newly designed energy-management twin-loop system.

Filed by General Motors, LLC

Seat Belts › Front

Model year 1995

If both the lap-belt and shoulder-belt energy management loops on the front seat belt assemblies release at or near the same time, acceleration forces can cause the buckle release mechanism to activate and allow the buckle to separate from the latch.

Consequence:

If the buckle released, the system would fail to provide adequate occupant restraint protection.

Remedy:

Dealers will remove the stitching that creates the energy management loop in the shoulder belt(s).

Power Train › Automatic Transmission

Model year 1995

The transmission shift-cable lock clip can back out of its installed position resulting in a loss of cable adjustment. When the shift lever is placed in the "park" position, the "park" indicator light may not illuminate.

Consequence:

The vehicle can move unintentionally if the driver does not notice that the indicator light is not on and does not apply the parking brake.

Remedy:

Dealers will adjust the shift cable and install a lock clip.

Power Train › Automatic Transmission › Cooling Unit and Lines

Model year 1995

Due to a thin case casting, an external transmission leak can occur.

Consequence:

This condition can cause transmission oil to sprayonto the exhaust system and result in a possible vehicle fire.

Remedy:

Dealers will inspect the transmission case assembly for the involved case casting. If the assembly is involved, the transmission will be replaced.
