I once read in a nissan forum that they took in their brand new 2012 altima to dealer for repair because the heated seats were not working. YUP THREE days after getting the new car. It turned out the car had the basic non heated seats installed in the assembly line so dealer had to order the correct heated seats. Just a thought..... if the assembly line were your truck was "born" also assemmbled other vehicles with similar parts maybe there could have beenn a mix up. I wonder if it means a check engine light but on the wrong spot.
On my older 94 ranger 4X2 i could ssee the 4X4 logo and 4LO if the sun shined on it. Maybe on yourr truck there was a mixup of that spot shouldnt have a light bulb installed on that spot or if it has the wrong instrument clusterr maybe the chek engine light is on or abs
light or something else. Get a sanner and chhek forr codes to rule out a code.
