Customer Question

My 2010 GMC Terrain has been stalling when stopped an intersections. Last year I received a letter about possible engine problems. Is this the case and is there a recall?
JA: Is the check engine light on? Does the car stall at idle or when driving?
Customer: The car stalls at idle. The check engine light just came on.
JA: Are you fixing your Terrain yourself? What have you tried so far?
Customer: not tried anything
JA: Anything else you want the mechanic to know before I connect you?
Customer: no
JA: I'm sorry but I'm not sure we have an expert who covers what you are looking for. Maybe if you give me more details I will find you a connection to someone who can help you.
Customer: The car seems to stall at idea and the idle speed is somewhat never sometimes. I have added fuel injector cleaner and that seems to work sometimes. I have seen that this is a common problems on some of the owners' message boards.
JA: Welcome! What's going on with your GMC?
