The Lincoln Navigator is an American full-size SUV that is out to offset the dominance of the Land Cruiser 300 Series, Lexus LX 600, and Range Rover, presenting a blend of a spacious & modern cabin, premium comfort, luxury amenities, off-road capability, and unrivalled towing capacity. However, like any other SUV, the Navigator is not immune to problems. The latest generation has tried to improve on the drawbacks of its predecessors, but some owners are still reporting common problems for different model years.
This guide covers the most commonly reported problems in the Lincoln Navigator, symptoms, causes, and practical fixes available in Kenya.
