| 65000 mi | Had to replace cam and lifters. I now have metal fragments from the worn cam and lifters floating around in my engine I am extremely concerned about long term engine life due to this problem. GM wouldn't admit any problem until I found the TSB's online. |

They ran the code and suggested that I replace the gas cap which I ordered from Amazon Genuine GM Yellow cap $9) light came on again I replaced the gas cap and CEL came on again and the tech traced it to a solenoid on the fume canister which he replaced under the emissions warranty.
