New to forum. I have a 2012 Journey w/2.4L. Last Saturday my wife and I were on our way from Mesa, AZ to Colorado Springs, CO when it died going down the interstate. After stopping, it started right up again and went another 70 miles then died again. This is 5:30 PM on a Saturday so Chrysler Customer Service wasn't much help. We eventually made it to Colo Springs. The further we went the more often it died and took a little longer to restart sometimes. It was towed to Dodge dealer on Monday and Tuesday morning I got a call from the service advisor saying they had looked at the veh and performed some kind of PCM flash update, drove the vehicle and pronounced it fixed. Has anyone had a similar failure? What fixed it? I find it hard to believe that a software problem could cause it to just quit running. The check engine light was on the whole way after the initial failure. She said it was a crankshaft position sensor code, but was generated falsely. I have to go back in a week and a half and bring it back and I have absolutely no faith that it will get me home. Sorry for the long winded post.
