When I bought the car, the brake rotors were warped so I had them turn them, no fee to me. 10,000k later same problem; took it the dealership; they told me it was the way I drive it. I said OK knowing that was not true. So I went and bought some from Auto Zone; 50 dollars per rotor, no big deal, still working fine.
Winter hits and there was a little bit of frost on my window from sitting outside over night, and it's morning time. I roll down the window and I hear a cracking noise, then the window falls down. Window regulator broke; took it to the dealership; 400 dollars.
Summer hits, my buddy rolls down his window passenger side, window falls down; window regulator. Ebay, 120 dollars, do it myself, not to hard, annoying though.
Same winter as the window regulator, the passenger side was blowing cold air. I recognized the problem, doing some research, and find it is very popular blend doors. So I don't fix it yet because the driver's side still worked. About 2 months later the driver's side was blowing cold air. Talked to the dealer and I tell them the problem; 960 dollars. So I went out and bought the parts for Chrysler myself, spending around 200 dollars on parts, and had a buddy put the blend doors in and new motors. He does it for 20 dollars an hour, and so he ran 200 dollars. It's a major repair; the whole dash comes off, need to add anti freeze, all that great stuff.
Now it's summer again and I went on a 12 hour round trip in it, made it home, went back out to park it after unloading my luggage, and the A/C doesn't work. I have reason to believe that it must be the dual climate controller switch, because sometimes it works then goes out, but also when it doesn't work, the heater doesn't work either, but that hasn't been proven yet.
01 grand Cherokee has been a headache. Pretty sharp looking but really a hassle as far as parts.
I owned a 98 5.9 Limited, loved it, so I bought the 01.
I also own a 94 grand Cherokee Laredo, I drive it to work; also a good truck.
