There's really no right answer to that I think it comes down to the dealer you deal with.
In my personal experience, dealerships will do anything to avoid honoring a waranty. Not just Jeeps...Kia, GM. They have their little tricks to f@#k you over. Here's a perfect example: We bought a 2008 Kia Sedona with all the bells and whistles. We bought it because of 2 reasons. 0% financing and the 5 year/100k bumper to bumper waranty.
2.5 years and 50k later the A/C stopped working. They recharged it (at a cost to us) and it still didn't work. we took it back for waranty and they said that if it was defective, they would cover it under the waranty, but the test (pressure test) to see if it was defective was not covered and that would cost us $700 weather it was defective or not.
BTW, I would never buy a Kia again based on the problems and poor service we had with this van.
