We took the Hummer in for oil change and because the engine light was on. Now they say a cylinder head is leaking. We have brought the Hummer in several times with the engine light on and they have never found a problem.
Now (after the warranty is expired) they find that the cylinder head is leaking and have a $3,200 repair recommended. I have now seen many posts similar to mine, is this a recurring problem with the 5-cylinder engine on Hummers?
