In terms of safety, the 2010 Lincoln Navigator is one of the best SUVs on the market, though as with any SUV, rollover safety is a concern.
The 2010 Lincoln Navigator scores three stars for two-wheel-drive and four stars for four-wheel-drive models in rollover resistance and five stars for front impact protection in crash tests conducted by the National Highway Traffic Safety Administration (NHTSA). However, as Cars.com points out, the Insurance Institute for Highway Safety (IIHS), which "has a more stringent testing process than NHTSA," hasn't tested the 2010 Lincoln Navigator.
ConsumerGuide praises the available rearview camera package, but is disappointed that it's part of a "pricey option package." The rearview camera is just an aid to the Navigator's otherwise excellent visibility, especially the "commanding view ahead," says Automotive.com. Cars.com likes the tire pressure monitoring system, noting that it's important to stay on top of with any car, and "even more so with SUVs."
