general problems of the 2011 GMC Terrain - part 2

While driving on the highway at 45 mph, the vehicle remained running but abruptly stopped. I could have been hit from behind with serious consequences. It left me stranded on a 2 lane road unable to move out of the lane. This is a serious problem with this vehicle. Gm needs to address this problem.

Vehicle(automatic) will stall while driving, has happened multiple times on freeway. Mechanics are not discovering any issues, vehicle has regular maintenance. There has been times where the vehicle would not go into reverse and would jerk then shut off, it seems there is an issue with gears/transmission. Have researched online and there are many similar complaints of stalling vehicles while driving.

While I was driving 35-45 miles per hour the truck turned off on its own so I parked truck on the side of the road. I waited a few minutes and tried to turn vehicle on again, it turned on again and I continued driving 20-30 per hour. Then after being stopped at a red light when it turned green I stepped on the gas and there was a loud sound plus we felt like it had jumped.

The vehicle was not taken to an independent mechanic or dealer for diagnostic testing or repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

The vehicle is consuming up to 2 qts of oil every 1000 miles. The low oil level light does not illuminate, even when the oil level falls below 2 qts low.

At approximately 80,000 miles, the transmission weight plates disintegrated, fouling the controlling modules. The transmission needs to be entirely rebuilt or replaced. First scheduled transmission service for this vehicle is at 100,000 miles. This occurred during normal highway driving, stranding us.

Vehicle transmission will suddenly drop into 2nd gear while driving and refuse to shift further. This caused vehicle to suddenly drop speed on highway from 65mph to 40 mph with no prior warning. Vehicle will also suddenly drop out of manual transmission mode, also without warning or indication.

Exhaust manifold cracked between cylinders 2 and 3 upstream oxygen sensor from hot exhaust gases from the leak passing on the wires and heater element within the oxygen sensor and exhaust manifold top heat shield. Carbon monoxide leaking through floor board.

I have a 2011 GMC Terrain about 62390 miles. When I am accelerating the car jerks. I took it to the dealer they state they could not find nothing wrong. I just got the fuel pump replaced due to a recall. And now a light came on that read ac off due to high engine temp but the temperature gauge showed cold and it never went to normal after being on for 20 mins and to this day is goes to the notch right before normal. Also when the fuel is low the light does not come on. I called the dealership and they stated they have to duplicate the problem to fix it but I cant bring it in until 12/16/2016 because they are booked.

We have a 2011 GMC Terrain that is 91,000miles. This morning on the way to work, underneath the car just making a huge clicking sound. When the car slow and stop, it makes huge wheezing sound and unable to shift when trying to accelerate. We brought to the GMC dealer right away (thank god, we were close to the dealer), and they said we need to replace transmission and it costs $5,000!!!! they say the fuel line has all kind of metals particle in it, so there is no way of knowing what exactly the problem is, it's better off to replace transmission. This car is under 91,000 miles and we have to replace transmission!!! I then do more research online just to find out there are many similar complaints about GMC Terrain's transmission problems. It all went down without any warnings and the car can't even make to 100k miles. I believe gm aware of this but choose to not fixing this, leaving the consumer to deal with the problem, since it happens shortly after the warranty expired. Transmission is most important part in a car, if my car can't even make to 100k without replacing transmission, what about other parts in the car?? how am I going to put my trust in gm car in the future? we love american car and support american products, but if gm couldn't stand up and fix the problem, then we'll be forcing to get different car other than gm.

Timing chain broke while reversing out of driveway into road causing engine to stop.

It has a loud knocking sound which gets louder with the a c on.

We bought this and had it three months when the transmission went out at less that 80000 miles. It lost power and also had lost oil after just having the oil changed. Supposedly it was "dry" and also no transmission fluid. It had just been serviced and have the proof of servicing. It took us three months to find a transmission to put in it, since we were still making payments on it!! had to get a rental car for three months. It was a nightmare. We both believe that gm knows this vehicle make and model transmissions are faulty. We were very disappointed. We had owned a jimmy with 300000 miles on it. Very disappointed in this vehicle.

We bought it used in 2013 and shortly after it started have serious issues . It started with the traction control light coming on and it power down. Then it would stay running spitting and sputtering after we turned the key off . So then we received a letter stating there is a recall and take it to the dealership to have it fixed . So they fixed it or at least they said it was , so we continued to drive it and the engine light came on and stayed on so I took it back and they said it was the throttle body and catalytic convert . Then we changed those parts and it still has the engine light on and spitting and sputtering after we turn the key off.

Oil smells like gas. Head linear fell down very poor gas mileage engine runs ruff has poor acceleration.

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.

2011 GMC Terrain. Consumer writes in regards to vehicle's performance and request assistance with repair the consumer at about 6,000 miles, the vehicle started jerking when picking up speed. The jerking would usually occur while increasing speed when it would get to approximately 18-40 mph. The vehicle also stalled twice; once when backing out of a parking space, and the second time when moving forward from a parking space. When driving the car for the first 2,000 miles, the consumer stated she drove the vehicle in standard mode. Thereafter, she drove in economy mode. When the vehicle started jerking and hesitating, she stopped driving in economy mode. When the consumer arrived at the dealer, she was informed a recall was issued 6-8 weeks prior. However, the consumer never received a notice. The recall was performed and the dealer stated the problem she was experiencing was an extension of the recall issue. The vehicle did not stall anymore after the recall issue was fixed. However, the jerking did continue. The consumer returned to the dealer, but they insisted there was nothing wrong with the vehicle, as it was a normal characteristic. The consumer went to the dealership where the vehicle was leased to have them inspect it. They stated the shift adaptive learns needed to be rest. The consumer stated after leaving the dealership and driving several blocks, the jerking returned.

Vehicle continues to be checked with dealer for awfully jerky, hard hitting transmission when changing mostly in low range gears. Service department continues to say transmission operating normal? vehicle has over 17,000 miles on it and continues to be plagued with jerky transmission periodically. Hard to believe there has not been a service bulletin on this problem?.

Vehicle has been in dealers service on several occasions complaining about the jerky transmission in first/second change. When changing in the low range transmission hits real hard and jerky particularly if pulling away from a stop at a moderate speed. Service department told me it would smooth out after break in period. Dealer claims transmission is operating normal and due to it being a 6 speed causes this. Hard to believe gm cannot fix to have a smooth operation. Vehicle now has over 10,000 miles and still has the same jerky transmission at low speed.
