The official notice
Defect
On certain vehicles equipped with a 5.4L 3-valve engine, the brake booster vacuum supply hose attached to the intake manifold fitting may swell over time and lose retention force. This could allow the hose to become detached from the fitting during an intake manifold backfire. Should this occur, the driver would only have a few brake applications with power booster assist before the vacuum reserve is depleted. When this happens, foundation brake function would be retained, but will require increased pedal effort. Extended stopping distances may result in a vehicle crash, causing property damage, and/or personal injury or death..
Safety Risk
No risk description available.
Remedy
Dealers will replace the vacuum hose.
