If you have some time go through the complaints year by year and you'll spend a day reading about the AZC HVAC system . They are of poor design and literally junk, and they aren't going to help anyone out, except tell you about the updated design and let you fork over about $1200 to one of their dealers for installation/parts.
Same as the junk heated seats, with the new design about $250 each seat, it will be up to the owner to do purchase and install, unless they were covered under the recall campaign. I could go on and on, how about the oil pans that rot out because of the material used? Leaking high pressure PS hose, brokem manifold studs, front brakes/rotors on the earlier WJ's.........
