Even though Consumer Reports typically hates Jeeps because they are far from a normal vehicle, they rated the 2007+ models very highly in reliability. I have owned 2 Chryslers ('98 Sebring convertibles) prior to my Jeep, and they both fared very well in reliability. Sure, they needed some work once they went past the 8-10 year / 100,000 mile mark, but what vehicle doesn't? Any vehicle you buy will spend time in the shop at some point, but Jeeps are far from being 1980's Hyundai's, Audi's, or Yugo's. Beware of broad generalizations.
