Welcome! New to the forum, not so muct the BU platform. Just like any other brand or manufacturer, the BU Renegade has had its good and bad seeds. I think it tends to be highly noticed 1) because of its big brother the wrangler 2) the forums give a lot more exposure to the common problems 3) problems generally coenside with reviews of a product. For most products you only see the bad reviews.
Im on my secone renegade (wish i never would have sold my first one) and i can honestly say that I love them. They are more capable than a lot of offroad enthusiasts will lead onto.
