Lincoln Navigator Problems

Check 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.

Corrosion on Battery Cable Ends

Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.

Rough Idle and/or Engine Stalling Condition

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 Recalls

Automatic 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.

Reverse Gear Engagement and/or Lighting Issues

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.

The Right Side, Second Row Seat Head Restraint May Fail

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.

We got the Navigator new. It is a wonderful truck but I'd say over the past couple of years we spent money getting few things all fixed on it. Changed four set of brakes, battery drained due of having the lights remaining on and leak in exhaust plus add we had to spend good bit on new catalytic and get emission system repairs. So far engine and tranny both have been great at 180,876 miles still...
I have a 1999 Lincoln Navigator too and I am having a problem with the lights staying on, battery drain, etc. We think we may have figured out the problem. We are finding that the rear hatch releases on its own, thereby turning the lights on and draining our battery.
