Runs fine until pushed uphill. Loses power after downshifting several times. Foot to the floor and little response. Engine rattles when shut down.

Yep, it sounds like the turbo is shot, this is what is making noise when the engine is shut off.

That's what I was thinking. Ugh! Repair is way above my pay grade. I will keep you informed as I go.

Yep, this is a common failure with these vehicles. If you can upload images of the turbo turbine that would be great.
