general problems of the 2008 Lincoln Navigator

The brake booster vacuum hose attached to the intake manifold fitting swelled over time and was close to detaching from the intake manifold fitting. This condition could allow the hose to detach from the fitting during an engine backfire, resulting in loss of power brake assist and increased brake pedal effort. As a result, stopping distance may increase and potentially result in a crash.

The brakes do not always function. Pedal goes down to floor. Brought to Lincolns attention last April, June and July. We have notes and letters with heather carlyle from Lincoln motor company.
