I bought it used and have put over 100000 miles on it, with the majority of those being interstate miles traveling from Tennessee to Wisconsin to visit family. I have had ac problems since the beginning, starting with having to replace the wiring from the firewall to the compressor, then I had the drivers seat break (again) as I turned into a parking lot. I have put 2 radiators in it. The MIL came on within the first year I had it. I replaced an o2 sensor and thankfully it passed emissions, but MIL came on a month later with the cat code, which thankfully somehow managed to go out when I neared emission time (this went on for 2 years), so I hurried and took it in to get tested. The last time was last Dec when it went out for 2 days, I ran it through, passed, and the light came on the next day and has been on every since. I have had to put a battery in it EVERY year because something is draining it. Yes, alternator has been replaced.
This is just the tip of the iceburg with issues I have had. Add to that the fact that there were so many complaints on here and other jeep forums as well as issues that really should have prompted a recall (drivers seat...blend door...resistor wiring...) and, hence my reason for going non-jeep this time around.
