NHTSA complaint #11244766, filed 2019-08, 124,000 miles“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.”
