You seem very angry over a fairly trivial problem (if you can look at the big picture).
Yes, it's inconvenient.
Yes, it costs money to replace.
Yes, it sucks that Jeep gives people a hassle about replacing them for free.
But, no, it's not worth getting bent out of shape over.
It's your prerogative to "never own another Jeep/Chrysler again" because of this, but that's really a really short-sighted decision. In the grand scheme of things, a broken window regulator is (or at least should be) the least of your worries.
Wait,wait, this is too funny. One buys a New Jeep and almost immediately the Windows start dropping like flies and let me tell you during a hard rain storm this really sucks cause the whole back seat is getting wet, speakers and wiring getting all wet, plus the Helicopter sound with one window open and only 90 more miles to go ISN'T REALLY INCOVENIENT. Taking a day off work to drive 30miles to get it fixed and then being told the Flasker Bob Pinion Clip needs to be replaced for an xtra $300, ISN'T REALLY INCONVENIENT! Sitting in a waiting room for 3hrs (here it comes, wait, wait...ISN'T REALLY AN INCONVENIENT! Spending time off from work, gas money to get there and back and paying for other made up stuff COSTS MY MONEY. And that mere THOUGHT that JEEP knows about this problem but would still rather replace the Whole Regulator, Window Track and WINDOW but STILL USING THE SAME PLASTIC PART rather than simply making a metal track guide is just plain....(here it comes, wait, wait wait for it)....STUPID!!
I preparing to trade my Corvette w/only 20K miles on it for a Jeep Sahara and soon as I do, I'll pull the door panels off and check for any plastic reg guides and redsign new ones so I don't have to make my Monthly Window Appts. IMO, the engineer that designed this little plastic window guide for the LIbertys should have one of these shoved up his little tail pipe.
Shame on you Jeep!! You should be very ashamed of yourself for treating your loyal Customers this way. Shame.
