Took our first road trip in the RAM this past weekend. It was about a 2 hour drive to the lake and it went well. The only thing I did "out of the norm" was turn on the tow/haul mode when I got into the hilly/twisties, which made it a joy to drive. The next day, the check engine light came on. While the light was on, I noticed that the ECO never came on. After dinner, the light went out and ECO would activate. Then the next day on the drive home that CE light was on for the entire trip and ECO never came on. Obviously theres some connection between the two....but its back to the dealership...AGAIN.
Anyone had this problem pop up?
