Against all advise I took my 2011 Ram Diesel in to the Valencia auto nation service department , ugh! They were right! I had an engine light come on and the code said it was the thermostat, so I called the service department to se if it was covered under the 100k power train warranty , they told me the only way they could tell if it was covered was to connect the vehicle to their diagnostic computer ( there is the lie) and it would cost 140$ to do this 10 second operation. (Huge rip off because my test unit had already confirmed the problem) then they tell me that it is not covered under warranty and it will cost me $550 to have it fixed. Thermostats cost less than 25 bucks. These people are rip off artists plain and simple! A word of advise, always call the warranty center at Chrysler and check on what is covered. My 5 year or 100k mile warranty is so limited that is is almost assured that I will never have anything that is covered fail. Shame on you Chrysler and auto nation ! You are what is wrong with this country!!
