I was blessed with the check engine light on a 2 month old Trail Boss. So disappointed with GM at this point. My 2014 GMC was a money pit and this is off to bad start. Yes, it is under warranty but 3700 miles is terrible. No idea what it is yet, but dealer wants me to schedule appointment and drop off. Why?? New truck and going down same path as previous. I post this out of frustration to GM considering I thought I could leave the previous money pit . Yes, this will be warranty but it is a sign of more to come. I hope other are having better experiences with GM

I am having the same issue and have not found a solution. Mechanic couldn't duplicate even though the engine run 1 to 2 marks past 210 with normal driving. Changed: water pump, thermostat, radiator based on internet searches and still overheats. AC is ice cold. Does anyone know if the dual radiator fans should run at different speeds as the truck exceeds 210 degree? Mine are staying at a low speed
