Guess I'm one of the lucky 0.2%. I got the letter last quarter, and they used a camera to look inside the engine to confirm the issue. I've had to wait almost six weeks for the parts to come in, but tomorrow I drop off my car for a full piston and valve replacement. It's a day labor, and they say the engine will be running like new once they're done. With 108k on my car, I'm looking forward to it!
