I'm new to the forum and new to the sonic, as I just bought my 2012 Sonic LTZ a couple weeks ago. When I test drove it, it seemed to drive just fine, although I wasn't really pushing it. After purchasing the car I noticed a jerking when trying to pick up speed and a very slow acceleration. Also, that it wouldn't really pull a hill. Going uphill I couldn't pick up speed with my foot on the floor. A friend of mine has a '14 and said his turbo went out and his did the same thing, until he had the turbo replaced. I took it back to the dealer and told them what it was doing. Luckily it was still under warranty and they ended up replacing the plugs and coil pack. The jerking isn't there anymore, but it seems to be lacking power. Not sure if it is just the car, as I'm not used to a small car, or there could be something wrong. I'm sure there is probably a thread on here where somebody has had the same issue, but I couldn't seem to find it. It is a 2012 LTZ with the 1.4 turbo and 6 speed manual transmission. No codes are in the system either. Any suggestions would be a help.
