Anyone know if cv joint falls under powertrain warranty (from what i read it does, but is there limits to what is covered?) I have a 2018 GT awd w/ about 41K, just had engine replaced due to cylinder head issue, had overheating light come on again last Friday. had it towed in to dealer. They sent video from mechanic showing inner cv joint leaked around the seal of the boot, somehow shot grease/lubricant on the water pump belt, caused it to come off. (if it's not one thing, it's another).
