I have a 2013 Dodge Journey Crew AWD, and I have started to notice that the MPG reader has been off the board lately. I was averaging 15.7 miles per Gallon, and then this morning it read as 4.3 miles per Gallon. It has been really cold where I live lately, but I dont think that a change of 11.4 miles per Gallon can happen due to the colder weather. Has anyone experienced this before, and if so what was the cause? I also called the dealership, and they could not give me a starit answer. Thanks in Advance.
