My check engine light came on abt a week ago and went in to Eagle Ridge GM in Coquitlam. Bill was $207 with no plan provided to me as to how to resolve the issue. The code was P0420, which relates to the cats. (I have the Borla exhaust) Brought the car to Carter GM in North Vancouver (where I purchased) and they were way more receptive than Eagle Ridge GM to my issue. Car goes to Carter on Monday morning and I hope to be provided with some options and hopefully even some warranty coverage as the car was advertised as GM certified with performance exhaust.....We shall see....
