. . . consumers, many of whom are loyal GM customers, say they're disappointed that there isn't a fix for the problems.

I had not heard about this earlier. Wonder how many engines are affected?

Sounds like a specific piston ring design used in some engines, but not all. The "fix" is a replacement short-block by GM. I suspect this is being done in some cases, as opposed to buying back the vehicle.

I'm curious whether any FReepers have had this specific engine knock experience & how it was dealt with by GM.

Engines made in Mexico???
