did you get the kit from
http://www.steigerperformance.com/ or have th dealer do it?
I bought my '06 in late '06 from an independant used car dealership. The CARFAX on it showed it had been used as a rental prior to that. My firt couple of regulator replacements were handled under the 3Yr/36K factory warranty - for free. Under this warranty I had both rear windows replaced as they failed (within only a couple months of each other).
When the factory warranty was running out, I opted for the extented one offered by the Dealer were I bought it (knowing by then the windows would continue to plauge me). Since then, I've had them all done "under warranty". I did have to cough up the deductable ($100) once as it actually lasted over a year, but since then, the shop has been pretty good about waiving it. (I've had the drivers side rear replaced 6 times total) It may help that not only is this a reputable dealership, but I've purchased sevral cars over several years there.
With the last replacement, I did ask for, and was given, the failed regulator assembly. My plan is to "Stiger-ize" it before it breaks again, or the warranty expires. I can only hope the passengers side (only replaced once) will fail under warranty so that I can get a spare to fix there too...
BTW, I have installed the suctiuon cup style window shades on the rear windows even though they are heavily tinnted. I've found this helps keep the window from sliding down into the door when it breaks. I also carry a roll of clear packing tape in the parts bag in the back for those roadside repiars...
