“'takata recall' just bought a 2007 z06 corvette and lately I've been seeing a lot of complaints about the valve stems breaking and causing catastrophic engine failture causing the power steering and breaks to fail so now I have to pay 5000.00 + to get it serviced and every 10k miles do the same thing because the valve stem and guides get hot and start to wiggle”

Luckily nobody was hurt but if I had been on a highway in the middle lane someone could have lost their life including me. From the second I realized the car was losing power to the point the engine shut off was a matter of 5 seconds maybe. …”

“I was concerned about excessive valve train noise and after reading several corvette forum threads about improperly machined heads by GM's supplier linamar, and that numerous vehicles have had valves drop and ruin the engines, I took my car with 27000 miles on it to a corvette specialty shop to have my valve guide clearance tested. I had (2) intake valve guides outside of service specifications, (4) exhaust valve guides outside of service specifications, and a combination of (10) other intake and exhaust valve guides at or near the maximum outside of service specifications. …”
