It's horrible. Takes off slow, burning smells under the hood, light on front passenger side not working at all. Changed light twice, still not working. Stays on for a couple of days then goes off.

O2 sensor light on and currently came back on after converter was replaced. Very annoying and irritating. Cannot pinpoint exactly what is causing the emissions to fail. Want to fix problem because worried will eventually ruin new catalytic converter. GM needs to man up and admit there is a problem with these cars.

Inconvenient, diminished gas mileage. Dealership says covered by warranty, don't know if GM or extended.
