What to check on a used 2018 Lincoln Navigator
Powertrain / transmission (20 complaints on the 2018): test-drive from cold through every gear and feel for slipping, harsh or delayed shifts and shudder; ask whether the transmission fluid has been serviced.
Engine (12 complaints on the 2018): cold-start it yourself and listen for ticking or knocking; check for oil leaks, low coolant and a lit check-engine light, and ask for oil-change records.
Electrical system (8 complaints on the 2018): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Steering (5 complaints on the 2018): check for a steering warning light, heavy or notchy steering at parking speed, and clunks over bumps.
Backup camera / back-over prevention (3 complaints on the 2018): shift into reverse several times and make sure the camera image comes up quickly and clearly.
