I am looking at buying a 06 H3 with 92k miles on it. I been looking around and found out about the cylinder head issue and the VIN# range effected ,which this truck fall into. The truck has a check engine light on so when I did the test drive I went by Autozone and had the code checked which shows to be a O2 sensor. The truck runs and drives great so now I am not sure what to do because I was ready to go on it.
,Looking for opinions is it work it or should I walk away?

 

Run a car fax on it or check the vin# with a GM dealer to see if the head was already replaced. More than likely, it was either replaced or by this time it would already have symptoms regarding the old head. Not every 2006 H3 in the vin# range will experience the problem.
