Our 08 Acadia is now having issues when we use the remote start. When you remote start and then go to unlock it with the key fob it will not unlock. I tried both key fobs and same thing. I even went back into the DIC and set everything up to factory specs but it still does the same thing. 
I've ruled out the engine oil, that isn't a contributing factor.
Has anyone else had issues with their GM product with remote start or key fob for that matter?
