 The Nav. system is a total disaster to the point of being a danger to use.The seats are like concrete and the passenger seat does not articulate. the remote start has no range and works maybe one out of ten tries. The Hwy Mpg is about the same as my 400 hp 2012 Ram 5.7 Hemi PU and worse than the 5.3 v8 Envoy we traded in.The tire pressure monitor has no gage. No oil pressure gage or volt meter? What is this 1959? Dome lights put out about 2 watts and the factory hitch looks like it was put in with a chain saw. Radar cruise control or the manual resume takes a week to regain the loss of speed. We just returned from a 2000 mile trip in this brand new car and my wife and I have never hated a car more. I have owned at least 25 new cars in my life and have never been so disappointed. I do not care how much it cost. This turd is gone!
