The short version

General Motors, LLC reported a problem with the service brakes, hydraulic. Here is what owners need to know.

WHAT

General Motors. The brake pressure sensor assembly may leak brake fluid into the brake pressure switch and cause an electrical short-circuit.

WHY IT MATTERS

An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

WHAT TO DO

Take it to a dealer — they will replace the master cylinder pressure sensor and inspect the wire harness, replacing it, if necessary, free of charge.
