2021 Lincoln Navigator: Problems & Reliability
CAUTION2021 Lincoln Navigator: CAUTION — 29 owner complaints, 1.1× the Navigator median year by raw count.
CarWhere's verdict score for the 2021 is 2.10, where 1.00 is a typical Navigator year once complaints are weighted for severity and spread over time on the road. That is past the 1.60 avoid line, but with fewer than 40 lifetime complaints in the engine's count it is capped at caution. Severity drives it: 66% of those complaints report a crash, fire or injury or involve a safety-critical system (engine, powertrain, steering, brakes or fuel).
