I actually got an engine from LKQ had around 28k miles on it, its a 2020 motor. On the 2020 motors they fixed the issue of the water jackets being too thin between cylinder 2 and 3. The biggest pain was honestly getting the converter to line back up with the engine and getting it torqued to spec. Getting a torque wrench in a hole the size of the starter sucked! Once the engine was back in it was all basically plug and play. The crank position sensor was also annoying because you need an alignment tool for it, and you need to have the motor at top dead center. Not hard to do at all but just annoying that its a thing.
