If you can buy an aftermarket warranty with a low deductible, it is not a bad purchase. Yes they get expensive at higher mileage but are not terrible to work on in my opinion. Common things I see at my shop with these are leaking water pumps (they are plastic and the plastic breaks, and they leak, they make an aftermarket metal one) injectors fail. Carbon build up on intake valves. Crankcase vent valve on the valve cover fail all the time. If you buy it, change the oil every 5k miles, full synthetic. Never go 10k! The engine will sludge up really bad overtime. I’ve seen it so many times.
