The MK's have really had very few issues. Even the beloved Toyota's have had recalls. I'm waiting to hear about the warranty coverage on this. If it was because of improperly installed trailer wiring then we have cautioned on that issue. The electrical systems are rather picky as to what you can and can't do.
Well, this is true, some of the newer Corollas that have been built in the United States the last few years are turning in some disappointing recall stats. Though they're still very reliable, it makes me dubious, even though that's all I've driven since 1988. And I must say my 11-year-old Corolla, the one I will soon trade, has never had a recall. So, you see I'm kind of spoiled.
But that's a little OT, besides I've always admired the Chrysler products from a distance. In fact, I LOVE the Pacifica but am quite sure that one would eat me out of house and home. Besides, it is a little larger than I need, and quite by accident discovered the cute-ute Compass. (And, I do like the looks of Compass, especially compared to it's ugly, shorter cousin the Caliber, which I would not buy on a dare.)
But back to the Jeep, what exactly do you mean by trailer wiring, also what model years does this affect? The OP didn't mention what year he/she had.
And, it's good to know that the Jeeps, Compass specifically, have been generally trouble-free. Places like the Edmunds forums really don't talk about them much, so it's hard to glean information, other than the fact that some call them loud and lethargic, that is, and of course "fan-boy" comments are always to be taken with a grain or two of salt. Somewhere in the middle is the truth! LOL
Here's hoping relatively few of these have had electrical issues. That's one of the things a CARFAX won't reveal, is what if anything went wrong mechanically with a car.
