Never heard of the oil pump problem either. Well of course the machine shop is going to say that, because they don't want any chance of a comeback whatsoever; on the other hand, the dealer is not going to be paid by the factory for throwing away perfectly good piston rings, and I can't see any reason to hone such low mileage cylinders. If you put in NEW rings, then yes, I'd hone probably. But the original rings, pistons and cylinder walls are old friends and very well acquainted.
Ring groove is merely a matter of placement. The ring sits in a groove in the piston. I presume a mechanic would not be so stupid as to not vary the notch in the ring grooves so they don't line up top to bottom, or at least check that.
If you're asking: could a mechanic make a mistake re-assembling my engine, the answer is SURE.

Well if you are loaded with extra cash one can suggest doing some serious engine work but if not and just wanting a little more out of your expectations do what I did.Magna-Flow exhaust and Airraid air intake unit. Low temp thermostat and new platinum plugs slightly off spark. AMAZING. Under a thousand bucks and worth every dime.
