Very Noisy Engine - Rattling Sound on Start Up - G

Stay away from the 4 cylinder. I have a 2011 Terrain with the 4 cylinder engine and i know that it is just a matter of time before the engine goes. It rattles on crank up, sounds like metal scraping against metal. Transmission jumps on occasion and the gas mileage is very much exaggerated by GM. It does not get near the mileage that they state in their bulletin on the Terrain. I would not recommend this vehicle to a friend.

Bought the 2011 Terrain used last month with 39k miles. It has stalled numerous times in traffic and check engine light is always on. I had to the GM service department and they can't figure it out. It uses 4 quarts of oil in 2k miles. GM tells me that is normal under their standards. I just pray this doesn't cause an accident with my kids in the back. GM prefers to not acknowledge this death trap.

Must be one of the most dangerous cars on the road. It WILL stall and leave you stranded on highway, intersection, or a parking lot. And you won't be able to get it restarted. It mysteriously loses oil and will require expensive repairs to get it started again with no guarantee the stalling will stop. You get no warning. GMC won't acknowledge the problem even though service departments have the replace parts packaged and ready as though they know the engine should be recalled. Will be donating the car to the local fire department to do car burning training rather than reselling. I couldn't sleep knowing I sold the car to someone who could die in it.

Where is the gas mileage?

We purchased a 4 cyl Terrain earlier this year. We like the vehicle overall but are very disappointed with the 21.6 MPG average over the first 9000 miles of driving. Most of the driving is on the freeway. Even on a long trip the best ever on a tank of gas was 23.5mpg. The main reason for us selecting the Terrain over other SUVs was the advertised mileage. We really feel we were scammed. I know that the EPA mileage to be questionable but to exaggerate the numbers by over 33% is almost criminal. Of course the salesman sold us on the 32 MPG but after talking to the service techs they tell me that there is no way that this vehicle can get more that 23 to 24 MPG. Of course now that we ha

On the three years I have had my car. I've had to fire air bag wiring. Told was not covered. I've replaced the manifold, catalytic converter, there was a oil consumption issue, this past week I replaced the thermostat and water pump. The backup camera hasn't worked great since the fixed the consumption issue. Didn't know the navigation was suppose to work with onstar until I read comments. Can't trade in because resale value is poor. I've pumped in over 6,000 dollars this car and the dealer had the nerve to say today. Think it's time to trade in. The only reason the consumption issue was fixed is my husband complained to GMC because the dealer wasn't listening.
