Buick sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.
The short version
General Motors LLC reported a problem with the service brakes. Here is what owners need to know.
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.
GM will notify owners, and dealers will replace the electronic brake boost module, free of charge.
