Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2011 GMC Terrain Owner Comments

Since I first purchased the car, it has given nothing but issues, the ac went out while still under warranty, it was fixed so I thought, it broke down again and because I was unable to describe word by word, I was told it would not be covered since it was not the same issue and I no longer had the warranty. A mechanic told me that GMC installed really cheap ac compresors/unit and he has had a lot of customers with same issue. It is a shame that we pay so much money in the purchase of a vehicle and in return we get a piece of junk. I need help.

Terrain was recalled for oil consumption and would stall about 500-700 miles after oil change because oil was at least 1 quart low. The dealership fixed it with the oil consumption recall parts and put less than 15 miles after the fix, the Terrain flat out died in an intersection when attempting to go at the green light. I almost got T-boned and rear ended because I was at the end of a green light with a car behind me and I couldn't get it started before the cross traffic's light turned green. Dangerous! I called the dealership and they said to bring it back. I'm just worried because I'm reading about several people with Terrains and equinoxes having this same issue with no end in sight and the dealerships not wanting to fix this serious issue. I checked the oil when I got it off the street but the oil was not low. It has never stalled when it was good on oil....this is a brand new, dangerous problem!

Car completely shuts down and loses all power/activity after starting it up, putting gear into drive, and trying to accelerate. Wheel gets stiff and car stops moving. This first happened within a year of buying the vehicle and has happened a second time mid ownership. During these times, the car just would not start for about 30 mins to an hour. Lately and several times a week now since mid-October, the car will start but completely shut down to the point where the car is shutting down at red lights, stop signs and anywhere I have to stop. It may take 3-5 times to repeat the process of starting the car and putting it back into drive before it drives without shutting down and me making to my destination.

Noticed "check engine" light came on when I turned on the engine. Since, I just bought the car the day before, I thought may be it need an oil change. So, I drove it but it stalled when I get to the stop sign in the parking lot. I turned the engine back on, drove about 15 miles and when I got to the traffic light, I slowed down to make a right (light was green), the car stalled and locked the steering wheel! I am thankful there was no car behind me. I just do not feel safe driving that car.

I bought a 2011 black slt Terrain 4/11/11 and has had problems with the noise it makes along with the amount of gas it takes and uses which does not add up to what they are stating when promoting this vehicle. It also is very fragile. You can not lean, fall, or close the doors to hard or it will cave in or dent. I really expected this vehicle to be excellent in and out only to now want to trade it in for a Buick lacrosse or lacern. My Terrain has 5,100 miles on it. I believed I was purchasing a top of the line vehicle with all the bells and whistles and ended up paying for a lemon with no seeds inside.
