Issue: On certain vehicles, the electronic brake boost may not work properly when there is a partial or full loss of vacuum-brake assist. As a result, the vehicle may not meet the stopping-distance requirements of Canadian regulations. Safety Risk: An increase in stopping distance could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to update the electronic brake control module (EBCM) software.
