Example complaints

“Broken or missing exhaust manifold bolts causing exhaust leaks. Potential for carbon monoxide leaks into the driving compartment. Upon researching on the internet this seems to be a very common and expensive problem. With GM engines from 1999 to around 2007. Just found this problem on my 1999 silverado on 5/20/16. I have owned this truck since day one and have an excellent service record at a well know dealership. Vehicle was stationary when the problem was diagnosed.”
NHTSA complaint #10870216, filed 2016-05, 120,000 miles“This truck has had an exhaust tic for many years. I just thought it was a lifter noise when in all reality while changing spark plug and wires about 2 months back I found the broken exhaust manifold bolts. Upon further research on the web I found this is an issue on 80% of these GM trucks. I think there should be a recall because of possible carbon monoxide poisoning while operating these vehicles and the emission problems encountered. Thank you for your attention to this issue.”
