I don't think a Chevy dealer is going to honor the warranty. I checked with a dealer who has helped me out in the past. I have to check my cars plate to see the date of manufacture. The clock on the warranty may have started slightly before 2009. At any rate, anyone following the manufacturer's service schedule is risking severe engine damage. That will be taken up with Chevy's CEO after my repairs are done. I would tell anyone to have their belts changed at 50 to 60k despite what the manual says.
