Smell of exhaust while driving. Noticed engine made a ticking sound which went away after engine got warm. Brought vehicle into a service center and a diagnosis of a cracked exhaust was made. Have noticed many other trailblazer and rnvoy owners complaints of exact same issue. Because of the nature of carbon monoxide poisoning in the cab I am entering this into the safety complaint database.

2005 gmc envoy xl - my car has died on me while going down the road on five different occasions. It has been to the dealer twice now, and they say they can't find anything wrong. I feel very unsafe driving this car, and I am afraid my family or someone else could get hurt. Looking online, I have found other envoys have done the same thing. One time it did lead to a death. I am hoping my complaint may be the one needed to do something about this dangerous problem. Each time someone has taken their vehicle in for this problem they get the same response I have gotten, nothing done!! My vehicle is still under warranty and I will continue to take it back in hoping they will find the problem. Please investigate this. It's very scary to be going down the road and your car just dying on you for no reason.
