2008 Pontiac G6 2.2L 4-cyl. Catalytic converter failure. I purchased the car in July-2008 specifically because I took a new job that would require a lengthy commute until the wife and I could relocate closer to my job. I have driven approximately 176 miles round trip daily between July-2008 and July-2010. At 90K miles, the check engine lamp came on. The local GM dealership informed that the catalytic converter had failed. They converter was replaced by the dealer on 7/29/2010 at a cost of $787 - including labor. 85% of the mileage was interstate miles, and the remainder was incurred on state highway or local neighborhood streets. Interstate driving was the typical 70-75 mph, and did not abuse or put my foot into it otherwise.
