CX-9 2.5T Engine Replacement

Anyone here have issues with the 2.5T? My CX-9 is currently at the dealer getting a new engine. An issue with a vibration at idle that was caused by loss of compression in one cylinder. Pretty shocked....thankfully, covered under warranty.
My dealer said I’m the first case they had, but Mazda has seen a few of these cases around. My symptoms triggered tech line to recommend a compression test.

What was the mileage on your engines?
Rough idle when in gear. It felt like a motor mount failed. That’s what I thought it was, or gummed up spark plugs.
Got my car back today. New long block. Runs great.
