Brakes
A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.
If the vacuum powered brake assist system fails to operate, the electronic brake control module (EBCM) has a software error that can allow the loss of power brake assist. The loss of brake assist would result in extended stopping distances and more difficulty braking which can lead to a crash.
