What owners say

I had a valve drop and threw a rod thru my engine traveling at highway speeds on a busy highway. I lost engine power, power steering, and spilled oil and other chemicals onto the roadway. A thick cloud of smoke billowed from underneath and out the back of the car making it unsafe for cars traveling behind me. The dealer who has since inspected my car has stated it is a known issue that the "lifters are weak". After quite a bit of reading, it appears many other owners of the same car have experienced a multitude of issues with valves, lifters, heads, etc. Gm is aware of faulty parts but I cannot find any notice of recalls. Make/model: 2009 corvette z06; engine: ls7.

My engine experienced valve guide failure while driving which resulted in a complete loss of power and spilled oil all over the road. The entire engine was destroyed. If I had not been able to pull over safely it could have been very dangerous.

I experienced an engine failure. This resulted in a sudden and complete loss of power at an unexpected time. This occurred during a high performance driver education event at auto club speedway in fontana, ca. There was no warning before the moment the engine failed. The cause of the failure was the head of one of the exhaust valves separated from the valve stem and fell into the cylinder, destroying the cylinder head, piston and cylinder wall. The engine model in my 2009 corvette is the ls7. A google search on 'ls7 dropped valves' will fill many pages.

There was a manufacturing error made during engine build with the valve guides. They are making a noise currently. This can cause the engine to fail abruptly and consequently one could lose power (engine) and thus loose braking assist & power steering assist and can cause a crash & could be fatal.

While driving on I-275 I first experienced a muffled noise in the car that sounded like wind. The car was not holding the road as it usually does and the rear swayed a bit. Next, there was a sound like a thump. My dashboard lit up like a christmas tree with a warning that traction control was not working and that I should seek immediate repair. Next, the vehicle lost a lot of its power and decelerated rather suddenly form 70 to approx 45 MPH. Car had no energy or pep and light said engine power loss. Fortunately nobody was behind me when the deceleration occurred. I exited the expressway and was just few miles from hotel and parked it. Had it towed the next day to a dealer in tampa. Do not yet know diagnosis on the car. Will probably hear tomorrow. But it was a real shock to have this happen so suddenly and the deceleration was sudden and if car had been behind me it could have been a problem.
