I'm new, first Jeep (2014 Grand Cherokee Overland). Love it. Hate taking it back to the dealer each week for "internal phone requires service," SD card working...sometimes, A/C not "on" during "Auto" climate control (I mean, who cares if it is 70 F in the cabin when it is 30 F outside if my breath and human moisture condenses on the windows all the time...that's what A/C is for...dehumidification), and no Uconnect successful linkage. So, great vehicle...Chrysler needs to high programmers and fewer grease monkeys!
