Recalls for the 2001 GMC Sierra: 7
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
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. 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.
Certain cequent 90 degree 7-WAY right angle adaptors sold by distributors in tow packages for aftermarket sales to tow 5th wheel RV travel trailers. Due to incorrect wiring of the harness, the trailer lights may not operate properly. If the trailer lights are not working properly, a vehicle crash can occur.
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 can cause increased stopping distances during low-speed brake applications, which could result in a crash.
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. If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
Aftermarket pickup truck over-the-rail bedliners manufactured for installation on 1999-2004 Chevrolet silverado and GMC sierra pickup trucks. The toggle wing assembly used to attach the bedliner to the truck bed is not engaging fully in the stake pocket of the pickup truck. The bedliner can become detached from the pickup while it is motion, possibly endangering following motorists or pedestrians.
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. 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.
