2006 Hummer H3 All Wheel Drive Automatic 31000 miles
3.5. 5 cyl. Vortec engine. While standing by my car I heard a small pop and a tingling sound and then found what appeared to be an exhaust bolt head lying underneath my car. Can't find where the head came from but am positive thats what it was. Bolt head letters appear to say 9.8 on head. What are the chances that I will have have an exhaust leak one of these days if I don't replace? Hummer dealer is 75 miles away even though still has warranty. Thanks much.
have the same problem?
