You may want to follow this thread. It's all about various issues but there is extensive talk about the recall.EGF3 said:I just received notice that my 2011 LTZ 2.4L is being recalled due to an emission issue. They claim the camshaft position actuator solenoid may stick, causing rough idle, stalling at low throttle, illumination of the malfunction light and poor driveability. The dealer will reprogram the engine control module and replace the camshaft actuator solenoid valves. I know many have complained about some of these issues so it's good GM is finally trying to fix the issue.
