Seeking advice on lifter and cam issues on the 5.3L engines with AFM for a 2009 Silverado
Out of nowhere my truck begins to make a hissing sound from under the hood and then my stabilitrac light comes, quickly followed by the service traction system light and engine light is blinking. I stopped truck immediately. Let it set for a minute, cranked it back up and it sounded normal for the first few seconds then it made the same noise and all the same warning lights came on. Had it towed to local dealership and now after 3 days they are telling me I have a collapsed lifter and worn cam....a repair to the tune of $3900. I'm literally only 55 days outside of the 5 year powertrain warranty. Seen a few forums indicating this is an issue and just seeking for guidance. I've contacted GM directly and awaiting to hear back, but in the interim it appears this is an issue and would like feed back from others experiencing the same issue. Any leverage or luck with getting GM to warranty the repair?
