My Silverado 2014 is in the shop right now. Went to start the truck, it didn't wanna start, did it a couple times, then it started, but on the dash, the "theft deterrent system" light came on. Called the dealer, they said to bring it in. But guess what, when I went to take it to the dealers, the truck didn't even start, no lights, no nothing, had to have it towed. It got down to dealers, and it starts up, they told nothing was popping up on the computer. I told them about the "theft deterrent light", so they tried again and it didn't start., they said their going to check the voltage and call back tomorrow. Hate this waiting game!!!!!!! S#it!!!
