In terms of safety, the 2009 Lincoln Navigator is one of the best SUVs on the market.
The 2009 Lincoln Navigator scored four stars in rollover resistance and five stars for front impact protection in crash tests conducted by the National Highway Traffic Safety Administration (NHTSA). However, Cars.com notes that the 2009 Lincoln Navigator "has not been crash tested by the Insurance Institute for Highway Safety, which has a more stringent testing process than NHTSA."
Cars.com notes that "tire pressure is always important to keep an eye on, and even more so with SUVs." ConsumerGuide offers "kudos to Lincoln for making a rearview camera available, but it's unfortunately part of a pricey option package."
On visibility, which the Lincoln Navigator 2009 has in abundance, Automotive.com comments, "once the driver gets comfortable, however, it's hard to beat the commanding view ahead. A Greyhound bus or tractor-trailer rig are about the only vehicles on the road that can obstruct the driver's forward vision in a 2009 Lincoln Navigator."
