Well, got the vehicle back today and inquired as to why the check engine light came on. They claim that these newer trucks are very sensitive and the light possibly came on due to the recall. If this is the case, that's total BS in my opinion. I asked the tech if it's possible GM is sending a signal to these vehicles to throw the engine light to get people into the dealership to get these recalls taken care of since most people probably don't bother. It would be crazy for GM to do this type of thing but if someone sees a check engine light, normally that would be cause for alarm.
