Wonderful vehicle. This is my second one. Discounts off of MSRP were too good to pass up. Very capable off-road with the ability to be upfitted with over-landing gear.

Reviewed a 2023 Jeep Mojave Crew Cab 4WD on Sep 20, 2024

This is the third day of ownership. So far so good. This is my second Jeep. The first one was a Jeep Wrangler Rubicon which I had for nine years. I was looking for a truck but test drove a Mojave. I was pleasantly surprised at how much they have improved and how much I fun it was to drive. The suspension is so smooth and it’s much quieter than my old Jeep. I like the mix of truck and Jeep.
