The only other option is not use it. I don't see how a G-Tech or a phone charger are drawing to much juice. Obviously GM has to much stuff on that fuse, as I seriously doubt there is something wrong with our cars.

 

I had the same problem and the dealer says it happens sometimes, and that the stock pplugs short out internally, so they put a new one in and its perfect... says it happens mostly if people use the cigarette lighter itslef... which i dont, i only use it to charge my phone

 

I only use it to charge my phone too. Oh well, dumb electronics.
