I have the 5.7 hemi in it. It's been a solid motor. Hauls a 3 place Moto trailer really easy.
A $10 seal on a transmission plug leaked, rear discs got chewed up rather quickly and the oil pressure sensor needed replacing last year. Also the clip that holds the sun visor needs to be replaced. A pressure sprayer will get passed sun roof seal - but rain hasn't got in yet. Tie rods were replaced last year. Edit: lower control arm bushings need to be replaced.
It's an AWD model, so the mileage is a bit lower than the standard 2wd model. When I got it, it was pretty consistently returning 22-24 mpg. Pulling a trailer with full size bikes brought it down to 18.5.
I've done a couple mods and put wider, 22" rubber on it. It's dropped to around 20 now. Still 18.5 with the trailer.
I've been thinking of getting a car top carrier for it. Then I could keep dirty, oily MX gear outside of the car.
