I didn't purchase it, but for having had to wait to take delivery due to the airbag recall, FCA said they would upgrade my standard warranty to a 10-year, and then it turned out to be a lifetime, full coverage warranty. So as long as as they don't try to do a lemon law buyback, I probably won't be selling my Compass for a long, long time.
That said, they say it's better to save the $ you'd spend on an extended warranty and set it aside or invest for when you'll need to do repairs. This is Jeep, though... knowing what I know now I'm very glad I have full coverage. I'm sure I'll be using it down the road.
