NHTSA complaint #10378859, filed 2011-01, 60,000 miles“The exhaust manifold on my 2005 Gmc envoy xl slt is cracked. I have researched and discovered many of these Gmc envoy and chevy trailblazers have this same incident occurring.”
NHTSA complaint #10301722, filed 2010-01, 82,000 miles“I have owned my 2005 envoy xl since june of 2006. Once, I passed 36,000 miles, I started experience lots of issues with my vehicle. I started hearing a knocking noise in the rear when I would turn on the AC and the steering was off somewhat. I had the steering fixed for around $400 but the knocking was going to cost around the same amount. Less then 10,000 miles later, the knocking noise is more persistent and is related to issues with the fuel pump. My gas hand will move to empty when I fill the tank up and will not move forward for days at a time. …”
NHTSA complaint #10264028, filed 2009-04, 38,000 miles“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.”
