I have a 2013 5.3 L silverado. I have previously only owned Fords. The truck has 68k on it. I have replaced the battery and the wipers so far. The computer tells me it gets 19.5 miles per gallon. It is 4 wheel drive. Have hauled my tractor and implements all over the country with it. I now have a dump trailer I pull with it. The electric seat will no longer work. I put a new switch in the seat and it still won't work. I understand it has plastic gears to operate the seat. Why would they use plastic gears?I will be dealing with this issue. It is an LT model. So far I do like the truck.
