2001 Chevrolet Suburban Recall

On certain vehicles equipped with an 8.1L engine, the crankshaft position sensor may fail. If the sensor operates intermittently, the Service Engine Soon (SES) light may illuminate and the vehicle may run rough. In addition, the engine may stall, and if so, may re-start immediately or after a cool-down period. If the sensor becomes inoperable permanently, the engine will quit running and will not re-start. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will replace the crankshaft position sensor.

A failure of this component (engine) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

Certain vehicles were built with fuel module reservoir assemblies that contain fuel pump wires and/or connectors that may overheat under certain operating conditions. Fuel pump wires that overheat may become exposed and result in one or more conditions; 1) If the ignition circuit wire is exposed and shorts to ground, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. 2) If sufficient heat is conducted to the pass-through connector, a hole in the connector may result, which may cause the Service Engine Soon light to be illuminated during the emission system diagnostics routine. Fuel vapour (and in some limited cases liquid fuel) may leak out of the fuel tank through the hole in the connector body. 3) If the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result. Correction: Dealers will affect repairs.

A failure of this component (electrical) may increase the risk of a crash or injury.

Certain vehicles located in Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador may experience unwanted Antilock Brake System (ABS) activation and increased stopping distances during low-speed brake application (less than 16 km/h and greater than 6 km/h). This condition does not set any ABS codes nor does it illuminate the ABS warning lamp. Correction: Dealers will remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply Zinc-X to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the output voltage to ensure the wheel speed signal is within specifications.

A failure of this component (brakes) may increase the risk of a crash or injury.

Certain vehicles fail to conform to CMVSS 209, seat belt assemblies. These vehicles have a condition where one or two sensors in the driver's and front seat passengers seat belt retractors may be inoperative. The seat belt retractors will lock when the belt webbing is extracted during a crash; however the mechanism that locks the seat belt retractor when the vehicle decelerates quickly, such as during heavy braking, may not restrain the occupant as intended during a crash, and could result in injury to the occupant. Correction update: None required as no effect on vehicle safety. See recall 04-158.

A failure of this component (seats and restraints) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

Certain vehicles have an internal component in the 2nd and 3rd row outboard seat belt retractor that could be cracked. With repeated actuation of the locking mechanism, the crack could spread to the point where the seat belt would no longer lock. In a crash, increased occupant injury could result from the no-lock condition. Correction: Dealers will inspect the outboard seat belts for specific lot numbers and replace the belts if necessary. GM is enclosing an inspection procedure for the owners to use or they can have their dealers do the inspections.

A failure of this component (seats and restraints) may increase the risk of a crash or injury.

Certain vehicles may have loose or missing rear wheelhouse plugs. Under certain operating conditions, exhaust gases can flow forward and accumulate in the rear wheelhouse. These exhaust gases could flow into the passenger compartment if the wheelhouse plug is missing or loose and may cause possible illness, unconsciousness or death. Correction: Dealers will inspect for loose or missing wheelhouse plugs, and install new plugs if necessary.

A failure of this component (structure) may increase the risk of a crash or injury.
