This page covers 3 recalls, 12 owner complaints and NHTSA crash-test ratings for the 2012 Lincoln Navigator.
4/5 Overall
NHTSA 5-Star Safety Rating
The dominant complaint pattern for the 2012 Lincoln Navigator centers on the powertrain, with transmission behavior drawing the most reports. Owners describe the transmission unexpectedly downshifting at highway speeds, in some cases dropping into first gear, which causes a sudden and jarring loss of speed. Related electrical symptoms show up alongside these events, the speedometer going dead, a service wrench warning illuminating, and the fuel range display reading zero. One dealer diagnosis pointed to a failing molded lead frame as the underlying cause. A smaller number of reports involve suspension and tire concerns, including tires developing belt separation despite significant remaining tread, leading to noticeable shaking at highway speeds. One report mentions brake fluid loss paired with a soft pedal requiring heavy pressure to slow the vehicle, though that appears in a single complaint rather than a recurring pattern.
