Chevrolet Silverado 1500 Recalls

On certain light duty trucks equipped with 4-wheel disc brakes, the Antilock Brake System (ABS) motor contains 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. The base brakes would remain fully functional, but the Dynamic Rear Proportioning (DRP) system, which optimizes front to rear brake balance, would become inoperative, increasing the likelihood of a crash.

Certain light duty pickup trucks and sport utility vehicles have a clearance between the front right-hand brake pipe and the body cross sill that could decrease to the point of allowing contact. If contact occurs and the brake pipe becomes damaged, there can be a loss of brake fluid and pressure. The brake warning lamp will be activated when the brake fluid lever reaches the indicator limit. 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.

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. 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 also require an increase in the applied brake pedal effort to achieve the same vehicle deceleration.

On these extended cab, 4-wheel drive pickup trucks, the steering gear to frame attachment bolts were not properly tightened. Over time, these bolts can loosen, allowing the steering gear to move, resulting in an unresponsive steering feel and noise to the driver. If this condition is ignored, the bolts can wear or fatigue to the point of breaking or the bolts can back out. If all the bolts break or back out, the steering gear will separate from the frame, resulting in a loss of steering control.

Certain 2-wheel drive pickup trucks fail to comply with requirements of Federal Motor Vehicle Safety Standard No. 120, "Tire Selection and Rims for Motor Vehicles other than Passenger Cars." The problem was caused by a computer error that resulted in the certification label listing tire size and inflation pressure information that differ from the tire size and the inflation pressure information for the tires on the vehicle. If the vehicle owner or someone servicing the vehicle inflates the tires according to the pressure specified on the label versus the appropriate pressure for the tires, the tires could be under-inflated or over-inflated depending on the tires mounted on the vehicle. If the tires are under-inflated, it could reduce the tread life of the tire, and the tire could degrade to a point of allowing sudden air loss. If the tires are over-inflated, it could reduce the tread life of the tire and increase susceptibility to road hazard damage. If sudden air loss or a road haz...

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. Additionally, if there is cargo on the tailgate the cargo may fall off if the support cables fracture.

General Motors, LLC (GM) is recalling certain 2020-2023 Cadillac CT4 and CT5; 2021-2023 Buick Envision; and 2022-2023 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

General Motors, LLC (GM) is recalling certain 2022 Chevrolet Silverado 1500 vehicles. The sensing diagnostic module (SDM) was left in manufacturing mode and not activated at the assembly plant prior to shipment. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

General Motors (GM) has decided that certain 2022 model year Chevrolet Silverado, and GMC Sierra vehicles equipped with an accessory sport bar. The accessory sport bar contains a high-mounted brake light that may not function. In addition, it may block the vehicle's existing high-mounted brake light. As such, these vehicles may fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 108, "lamps, reflective devices, and associated equipment."

General Motors (GM) is recalling certain 2019-2021 GMC Sierra 1500 and Silverado 1500 vehicles equipped with certain accessory road tires and a 17" spare tire. The 17" spare tire provided with the vehicle is not compatible for use with the accessory wheels, which can cause the anti-lock brake system (ABS) to not function properly under certain conditions.
