could be the auto start-stop engine feature which is supposed to save gas. I believe it creates extra wear on the engine and I deactivate it when I start the truck. I understand there is a way to permanently deactivate it which is available to purchase.
Great looking rig. I have a 2019 XLT Super Cab FX4. I'm going to replace the Hankooks that came with it with something a bit larger and more aggressive... what led you to pick the tires you're using?
Thanks
