Lincoln Navigator ProblemsCheck Engine Light Due to a PCV System Vacuum Leak
A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.
In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

Lincoln Navigator RecallsAutomatic Transmission Shifts To First Gear Unexpectedly
The vehicle's automatic transmission may shift unexpectedly and suddenly into first gear while driving, which can result in a loss of vehicle control, sudden slowing of the vehicle and possible transmission damage. Dealers will reprogram the powertrain control module with updated software free of charge to resolve the concern.
Certain vehicles may have been assembled with a transmission range sensor (TRS) that was calibrated out of specification for reverse gear. If this condition exists, the transmission may not properly engage reverse gear and/or if reverse gear does engage, the "R" indicator on the dash or the backup lamps may not illuminate. These conditions increase the risk of a crash or a pedestrian being struck due to the vehicle's not signaling it is in reverse. Dealers will inspect and replace the transmission range sensor as necessary to correct this concern. The Ford recall number is 12C23.
These vehicles may have inadequate welds on the head restraint support brackets for the second row, right side seat. In the event of a crash, the head restraint may not provide adequate protection, increasing the risk of personal injury. Dealers will replace the head restraints as necessary to correct this concern. The Ford recall number is 12C22.
