The first time it happened was right after the first oil change. We had left the dealer and had driven about an hour and a half when it lit up. Scrolling through the screens we discovered our fuel filters were at 8% but nothing else alarming. I checked my email for more information but there was no warning email. Looking at the manual, I was relieved to see that as long as it wasn't blinking it was ok to drive. About that time, our salesman called to ask if we were pleased with the service. Of course, the light was now off and he had no great words of wisdom and wasn't able to tell me anything I didn't already know.
The next time it came on I actually received an email stating ! POWERTRAIN...your vehicle needs servicing. I called the dealership nearest us and explained what had happened. The service manager laughed and said the light has nothing to do with the powertrain, it is most likely an emissions issue. He was more than happy to look at it but could not fit us in until the following Tuesday. Unfortunately, we were leaving the following Monday. He again assured me it was fine to drive as long as it wasn't blinking. I thanked him and made plans for the next town.
The young man I had set up the appointment with met me as I pulled in. I went over what was happening, gave him the email and also a new email I had just received that morning stating everything was good. He was friendly and confident but concerned that the light was not on. He had a service tech go over it both for the engine light and the email I received in regards to the powertrain. As we earlier concurred, they were unable to find anything wrong. Lamar told me to bring it back as soon as the light came on again. I agreed and a few days later, Thursday afternoon to be exact, I pulled back into service. He worked his magic and pulled the code from the system. Turns out the code referenced the air suspension. I had our dogs with me and it was late in the afternoon so I agreed to bring it back in the morning.
The next morning he let me know he had done some research on it and was pretty sure one of the modules was having a communication issue. He would have his tech dig into it. I caught the shuttle back to the hotel and the dogs and I had a mostly uneventful day. About 1 o'clock I called him to make sure he hadn't forgotten about me. Close to 5, I called him again but this time to let him know Brad would be there to pick it up. His crew would drive by the dealership on their way back to the hotel so it made sense to have him dropped off rather than me picked up. This is when he let me know there is another truck there having the same symptoms as ours. It has been in and out of there a few times. Apparently, a different service guy and tech have been working on it and now have a request out to Chrysler. He went on to say that instead of working on both trucks, they would continue to work on the first one until they have a solution and then have us bring ours back. I told him I much appreciated not being the guinea pig but hoped that a solution would be on the not so distant horizon. He seemed an optimistic fellow and that by Monday afternoon they should know how to proceed and what parts to order.
Monday has come and gone without a solution. Lamar has kept in touch with me and given updates on what they have done with the other truck. He still seems very optimistic...
UPDATE: FEB 5, 2017
A software update was done on our truck. It has been about 3 weeks without the light coming on.
I suppose you will now have to wait for Part 2...
