Recalls for the 2020 Chevrolet Silverado 1500: 12
The transmission control valve may fail and cause the rear wheels to lock up. Rear wheel lock up increases the risk of a crash.
The transmission control valve may fail and cause the rear wheels to lock-up. Rear wheel lock-up can increase the risk of a crash.
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. An ABS system that does not function properly can increase the risk of a crash.
The affected tires were cured for too long during production. Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
The seat belt brackets may not be secured to the seat frame in the front-row center seating position. If a seat-belt bracket is not secured, the seat belt may not properly restrain an occupant in the front-row center seat position, increasing the risk of injury in a crash.
The vehicles may have been manufactured with Continental tires that were overcured. Overcured tires may experience a carcass break in the sidewall resulting in a sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. Either condition increases the risk of a crash.
One of the driveshaft joints may not have been properly welded, causing the driveshaft to separate while the vehicle is moving. If the driveshaft separates, there may be a loss of propulsion, increasing the risk of crash.
General Motors, LLC. The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment. If the diffuser separates from the inflator during deployment, RRAB performance may be degraded, increasing the risk of injury in a crash.
The bolts used to attach the front and/or rear brake calipers may have not been heat treated and may break under load. Broken caliper bolts can reduce brake performance or interfere with wheel rotation and increase the risk of a crash.
The battery positive (B+) cable rings may have been manufactured with excessive glue, potentially causing an intermittent electrical connection between the B+ cable and alternator. An intermittent electrical connection between the B+ battery cable and the alternator could cause the vehicle to stall, increasing the risk of a crash.
The fuel pump may be missing a pressure regulator, allowing for over-pressurization of the fuel system. Over-pressurization can crack the fuel pump and cause leaks, increasing the risk of a fire in the presence of an ignition source.
When the front seat belt pretensioners deploy, hot gas may vent through an opening in the pretensioner bracket, possibly igniting the carpet. A vehicle fire could result if materials ignite inside the vehicle.
