Equipment:mechanical:accessory scissor/screw/bottle jack/lift:stand

General Motors, LLC. (GM) is recalling certain 2020-2022 Buick Encore GX and 2021-2022 Chevrolet Trailblazer vehicles. The emergency jack, if not positioned as directed in the vehicle owner's manual, can fracture while in use.

Service brakes

General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.

If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.

Seats:critical fasteners

General Motors LLC (GM) is recalling certain 2020 Buick Encore GX and 2021 Chevrolet Trailblazer vehicles. The rear attachment bolts of one or both front seats may not have been installed.

If an occupied front seat is missing the rear attachment bolts, it may move during a crash, increasing risk of injury to the occupant.

20V295000 2020-05-21
Tires

General Motors LLC (GM) is recalling certain 2021 Chevrolet Trailblazer vehicles factory-equipped with optional 17-inch sport terrain tires. The certification label on these vehicles does not provide the tire size and cold tire pressure information for front and rear tires, as required. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard Number 110, "Tire Selection and Rims."

If drivers are uninformed and overinflate or underinflate their tires, this may increase the risk of a crash.
