Defective Genesis?

[Truman Gee]

My 2009 Genesis has the 4.6 V-8 with 86,000 miles. A couple of weeks ago it just started running very rough (missing) but with no obvious cause or noise. Limped it to the dealership, where it has been for almost two weeks. First they said it was a computer problem but that did not fix it. Now they say it broke the valve spring on cylinder #5 and the valve dropped down.

Has this happened to anyone else on this 4.6 engine?

Hope thay gave you a loaner. Also you may be in luck if they give you a new engine.
