Fortunately, I have not had those kind of problems...just BAD gas mileage. I tell everyone I can "Stay away from this vehicle - it is a gas hog!" False advertising - I don't care if EPA says 32 mpg - it doesn't get it.
My Toyota Camry Hybrid gets what the sticker stays - 39-41 mpg.

This sounds interesting - wonder if they will actually contact us for a "fix?"
My 4 cyclinder could use some help - gas mileage is horrendous - and I drive very conservatively.

Sorry everyone isn't getting the gas mileage they wanted, but the culprit here in the EPA. It's the EPA who estimates mileage, and the manufacturers simply post that result. Further, if you read below the BIG NUMBERS, you'll see there is actually a broad range of mileage that you can expect to get. Just another gubmint scam.

I own a 2010 Terrain have had it since January of 2010. I would like to mention for me in the city of Chicago the fuel consumption has been what is expected I have the 2.4lt. 4cyl. and get an average of 26mpg mix city and hwy and for a long road trip to Nashville got 36 Mpg and that was my calculation not what the car displays. I was very impressed.
Now the problem I do have with the car is that like everyone else I get a rough idle and it has turned off on me a couple of times at red lights.
The cam has been replaced, oil pump, timing belt (chain), and fuel pump. after all that I still get a rough Idle and a rattling sound the dealer told me, that is how that engine should sound. It is louder than any 4 cyl diesel.
Who do I need to talk to for help? It is not normal for a car at 25k miles have this much work done to it.

Good morning bishop07,
I'm sorry to see that your Terrain has a rough idle, and that the different repairs you listed haven't helped to resolve this. If we can check in on this situation with your dealership for you, please send us the following information to socialmediagm.com: your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your involved dealership.

Appreciate your response. Minor correction to your stats - the dealer drove my car 63 miles and supposedly started it successfully 70 times. They didn't have to drive it anywhere to reproduce this problem. They used my car as a taxi and not for the purpose of replicating the problem I clearly reported. Since picking up my Terrain from this "service" appointment I have been keeping a log of every time I start the car. I record each start whether it is successful or not. From 4/11/2012 through 5/17/2012 I have attempted to start my Terrain 115 times. It failed to start on the first try 26 times. Do you still believe the dealer started the car successfully 70 times in a row? There is a problem and GM has no idea how to fix it. As for escalating the issue, I tried that - I called and wrote to GM. As a response, GM Customer Support closed the file that they opened for me in April. In their world the issue is dead. Now that I have documented 5 weeks of data I will try another GMC dealership. I have little faith it will be corrected - we'll see.

Brutal. My 2012 is 200 miles old and has stranded me twice. 2 new fuel pumps and still no successful solutions. Here comes an engineer to the dealership to try to solve my problem. I want out from under this sniper...gmc wants to keep fixing it.... Go Gm!

Good morning rtick,
Have you opened a case (71-**********) with our Customer Assistance Center on this as of yet? If not, we'd be happy to look into this further with you if you wanted to send the following information to socialmediagm.com: your name/Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your involved dealership.

hi devs1... if dealership does not inspire confidence, it is fine to try another one, but of course can be difficult to travel to a different one sometimes.
a failure-to-start that strands you is a glaring 'drivability problem', so if that's the case then after a certain # of days-in-shop/attempts-to-fix, the vehicle can be administratively lemon-lawed in many states. maybe your state has lemon-law?
either way, i believe the adage 'do not attribute to malice what can be explained by ignorance' and that a well-intentioned 'taxi driver' like the courtesy-driver or parts-driver for the dealership might not notice an occurrence of fail-to-start, especially if started fine with an immediate-retry. a technician specifically looking for starting problems would not make that mistake, however.
btw, are you using the lowest recommended octane? (87 near sea level). premium fuel is harder to ignite by definition - it makes for harder starting, and provides zero benefit for most engines, probably including the terrain's.
