well i have 35,000km on the eco diesel and its finally in the shop. we have had a string of -30 to -40C weather here lately and a list of things started happening. starting with my DEF tank ceasing to consume DEF. which was hard to tell at first till it kicked on a message saying service def tank, followed by a electronic throttle control message an hour after that. which i found left me with only first gear and a maximum speed of 60km/hr. parked it for the night and everything went back to normal the next day except the check engine light and lack of def consumption. made a service appointment for it to go in and the day before it made it in, it put me back into what i guess is limp mode (1 gear?),ETC light back on. i was told by service tech today that my air intake valves that control air amount froze up. and they found a bunch of water and ice in there so engine and turbo was not getting proper air...!!!! then they told me that its because i dont have a front end cover and if i did buy one that it would fix all future problems..so is chrysler now designing trucks that require additional spending so they can run properly in cold weather?? are these trucks not "extreme cold weather tested"?? has anyone else had any cold weather/snow issues with theres? i cant help but feel that if the cover is the fix then it should be covered as a warranty item lol as it should be mandatory to include them in first sale of these trucks.
