78000 miles, timing chain issue, spun rod bearings, and low compression in the engine. Oil and maintenance done on a regular basis. Check engine light did not go on, no warning signs, and did not automatically shut off, kept running. I was going 40 miles per hours on a highway, was driving and started hearing the engine sound like a tractor trailer, hearing bangs every 3/4 of a second. Hearing multiple reports on Camaro forums about this, and nothing is being done, chevy said it is an owner issue, I needed to get my entire engine replaced because of it. This is not normal for 78,000 miles on a car, but I guess that is why they brought their power train warranty down about the same time people started reporting these issues. Contacted gm directly and they said their was nothing they can do about it but make a report about it, and if they ever come around to a recall they will pay me back the cost of the prior repair.
