Got the dreaded light at 2100 miles. Took it to dealership last Tuesday. They came back and didn't even show me a code but the repair slip showed that they reflashed the PCM. Drove it home then yesterday the light came on again yesterday. DAMN and I told them last week I had a +2K mile trip this Wed. Took it to dealer and got an appointment for Monday first thing!! This shouldn't be happening on a brand new truck. Also noticed that after this check engine light the remote start function doesn't work correctly, truck starts then shuts off when you unlock the doors.
