It's not just their reputation . My son-in-law is a master mechanic and a Jeep was my 2nd choice but he told me he would refuse to work on it if I purchased it. they have so many problems.Maybe some time ago but I don't think that's the case over the last few years.
I came from 4-door Wrangler that I specifically built how I wanted it (just like the Tesla) and had delivered in 5.5 weeks. Unfortunately I totaled it 27 months later but in that time I had zero issues with it. Just like on these forums there are tons of complaints about reliability and major issues all over the numerous Jeep sites. Unfortunately for Jeep this is their reputation so people cling on to that notion without really knowing anything. Hopefully the Model 3 can continue it's good reputation and spread to the masses
