This vehicle has pumped through 5-7 quarts of oil appx every 500 miles. I know that this is not normal. Car was overhauled, the trans was basically rebuilt, with new components.problem with oil evaporating at very low mileage still an issue. ** leaks*** or symptoms aside of diminishing oil every said set of miles. Very frustrating issue that hasn't been resolved.

The catalytic converter makes loud popping noises on passenger front side. Now is misfiring in cylinder 1 and also has unexpected gained speed without any gas peddle pushed. GM extended the catalytic converter warranty to 200,000 miles due to converter problems. But my VIN they say isn't included. My car is a V6. My sister was the previous owner she said she never received any recall information. The website shows no open recalls but the work wasn't completed since she purchased in 2007. GM website doesn't help at all.
