Cons

  • The EPA-estimated annual fuel cost is $4,000.

  • NHTSA ratings listed here are 4 stars for frontal crash performance and 3 stars for rollover performance; other safety ratings are not provided.

Alternatives

For a Jeep pickup comparison, consider the 2027 Jeep Gladiator 4WD. Shoppers considering a Jeep SUV can also look at the 2027 Jeep Grand Cherokee 2WD or the 2027 Jeep Grand Cherokee 4WD. The listed alternatives are different model years or vehicle families, so these facts do not support a direct fuel-economy comparison.
