I would like to know if any of you having this same problem ever found the solution?? I just got my 2014 Silverado that has remote start. (fob only as far as I know. If there is an app, I’m not familiar with it yet ). Most of the time the remote start works just fine, but randomly it wont. Today as I was walking to the truck I heard the very fast bump of the starter like someone mentioned above. After that I tried unlocking then lock/start multiple times and it didn’t attempt again. Started the truck and no CEL. Any help is appreciated
