Jeeps have turned into POSs since the govt bailout.takeover of Chrysler, and ultimate acquisition by FIAT.
My family purchased a Jeep Cherokke Laredo in 1988 and it ran well over 25 years and racked nearly 275K miles.
I would bet anything these new ones barely make it to 150K
Have a friend with an older Cherokee - has a lot of miles, but it also rides weird and sounds like a bucket of bolts.
I believe the only new Jeep with body on frame construction is the Wrangler.
Other Jeeps are no more rugged than any other vehicle, and may be a bit costly for their specs. Modest vehicles easily pass 150K miles, but by then they almost always have many very annoying small problems.
Most of the suv these days are creampuffs with a long turning radius, etc. A compromise between a passenger car and a 4WD. Not something that you'd want to take offroading.
