Just bought my truck last week. 2015 GMC SLE, 20" wheels 35x12.5 tires 6" fabtech lift. It doesn't happen all the time but most times while I'm turning (not turning as in changing lanes, more so turning off a street) and on the gas the traction control kicks in and the gas pedal shudders. I've been reading a lot about vibrations in the steering wheel and gas pedal when reaching a certain speed (I don't have that issue) but no so much of my issue. Anybody else have this issue with their lifted truck?
