Brakes: the brakes do not stop the vehicle without excessive pressure to the pedal. Especially carrying a trailer with the exhaust brake & trailer brakes in effect. Takes excessive distance for vehicle to stop. Pedal must be pressed 3/4 to the floor for it to start to apply brakes. It is extremely difficult to stop this vehicle at any speed over 45mph. Have not taken to dealer, was expecting a recall but none until now. Steering: when I turn the steering wheel at low speeds such as backing into a parking spot, there’s a loud squealing noise c…

General Motors, LLC.

Consequence: An ABS system that cannot control the rear wheels independently increases the risk of a crash.

Remedy: Dealers will provide the appropriate spare tire and apply a new spare tire information label, free of charge. Owner notification letters were mailed on October 18, 2021.

The bolts that attach the brake pressure modulator valve (BPMV) assembly may not be properly tightened, which could fail to seal the two sub-assemblies and allow water intrusion.
