   Issue: On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump.

Safety Risk: A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct you to take your vehicle to a dealer to reprogram the electronic brake control module.
