A buddy of mine has a '10 GMC Terrain, and it's surging when he decellerates. He said it's a surge of about 1000rpm. It's definitely a problem! The vehicle is still under warranty, but when he brought it in to the dealer they said the problem was hardly noticeable (if at all), and they didn't fix it. I told him to bring it back and make them fix it, and don't leave until they take the vehicle and give him a loner. I was just wondering what the problem could be, so he might have a little more ammo. on his next visit to the dealer. Thanks in advance.
