All Warranty information is clearly available, nothing is hidden, that would be illegal? I take it your mechanic does not work for GM so why not ask them for additional information, in certain circumstances they could even do the work and get paid!I've been told by my mechanic that GM has a "hidden" warranty that covers a turbocharger failure up to 100,000 miles regardless of the year of the vehicle. I have a 2011 Cruze with 90K miles that I bought used and my mechanic said there is oil in the inlet that is a sign of imminent failure. Not sure if anyone else has heard of this warranty. Just trying to get as much info as I can before contact GM so I don't sound too much like a goof.hmy: Thanks!
