When I stop at the light my car shake and rocks, then the car goes into limp mode. Where the stabilitrack comes on and the engine goes into reduced mode. And I can't go over 30mps. When this happened on the freeway is the most dangerous and scary feeling ever. I've got So many new parts and put over 3,000 into the car and it still has this issue. I've been do several different mechanics and nobody can figure out what's wrong. Gm needs to look into this, it's so many forums going on for this issue.

Once again, timing chain incident, this time while driving, wasn't expecting it, suddenly my Terrain steering when became stiff to turn, and happened to realize the car motor had shut off and rolling to the right, nearly hitting parked car. I tried to start vehicle, but made a whining sound, but did not start, yet check engine light was on. I had my OBD reader handy, and got p0011, p0017 codes, which tell me it was the timing chain again in this car. This very dangerous because we could of collided with a parked vehicle, if not for me struggling so hard to steer vehicle while steering wheel was stiff.

Very high oil consumption. I recommend it's the piston rings

We received a notice in the mail regarding our vehicle with our VIN #. And it mentioned our particular size engine had a recall for potential emissions part condition of degraded catalytic converter and/or oxygen sensors caused by excessive engine oil consumption affecting some vehicle from our year, make, and model. We were surprised to receive this notice because we always park in reverse and we had noticed how it was turning the curb side black coming from the tail pipe. We did receive one other notice before and took it to the dealership to have it maintenance but my honest opinion I do believe they did anything to our vehicle because it was running the same and also took it to Midas after taking it to the dealership because it ran the same. Anyhow I hope upon receiving this other notice we can actually maybe get reimbursed and actually get it fixed finally.

Vehicle began to use excessive amount of oil and idel up and down and sometimes even shuts down. After about 3 months while driving on the interstate it began to shut down while in motion. I called for someone to check the vehicle out and he arrived called someone to check the vehicle and he actually told me it seems to be the motor gone bad but he asked would I drive it back home if he followed behind. It literally scared me and my 4 children to death when it shut down while in motion with that kind of speed so I don't trust putting my children in it now. I don't think its safe at all. The vehicle I once thought was perfect for my family is turning out to be a nightmare.

My daughter was driving to a friends house. She lost all power, and the vehicle would not start back up. There was 3/4 tank of gas in it. We had it towed to a nearby shop to have it looked at. Upon the vehicle leaving it had a lot of gas on the gravel road. When it made it to the shop there was obvious fuel line issues. This vehicle has not been fixed yet, still waiting on a replacement line from a dealership. This is something that GM should have had recalled and fixed immediately. This might have been an issue that would have been fixed due to it still under a manufacturers warranty, but I do not have access to that. The shop where the work is going to get fixed at said this was covered up to 150,000 miles. If this was an issue to that mileage, it should be extended to the life of the vehicle.

The truck burns oil incredibly fast. Due to this ongoing issue, it caused the timing chain to break and we had to spend nearly $800 for engine repairs. Even after having it in the shop numerous times for the same issue, the truck still eats through oil incredibly fast and it seems to only be getting worse. I received a letter in the mail saying that there was a recall regarding this but that they would send me info through the mail on how to go about fixing this issue, but I never received anything else about the recall.

My Terrain is stalling really bad some days and sometimes no problems at all. It does it more when going into reverse, I have to keep giving gas to get backed up. It has also died on me when I slow to a stop like at a light. This is really frustrating!!

I was driving my 2012 GMC Terrain and as soon as I slowed down or stopped my car would shut off and I would have to try to restart it. Fortunately, I made it home without having to stop. As I was turning in my driveway it shut off again. Onstar suggests it may be a timing issue. Help! I took it to the dealership to get a new battery and when I got my car back the fuel sensor was not working. It was working before they got it and GMC collierville refused to fix it.I can't afford all these major repairs and will not by another if GMC does not resolve the consumer's issues.

My car oil consumption is excessive. I have repetitive codes: P0089, P0300, P0366, P228D, P0014 and the check engine light being on. Car is jerking back and forth when at a stop light. Tapping noise made also. Every 1000-1500 my car is always needing oil (at least 2 quarts) and I also have to put more than the usual amount of gas in it then when I first purchased.

2012 gms Terrain 4 cylinder flex fuel- camshaft code, cam sensors replaced, spitting and sputtering, stalled X3 and shut off, fuel consumption noted, loss of power. GMC dealership refused to perform diagnosis on my car due to my refusal to pay for ruling out the documented fuel leak recall/special coverage. My request was only to have fuel the issue looked at and ruled out, nothing further, to ensure this was not causing my problem. I reported my problems that are consistent with the noted fuel special coverage and turned away because I did not have $120 to pay if they found it was not the problem. Upon reading my issue correlates with numerous Terrain and equinox owners. I want in this action to get something done for people like myself.

As I was driving down the road at 55 mph hour my SUV began to shake extremely and was throttling at very high RPM's and the SUV thrash to sudden halt and continued to shake and idle very high and loud. I tried to hit the gas to get myself off the road as I was on a 2 lane highway with my 4 year old son in the car, and the engine revved and the RPM's spiked but I went not more than 15 mph, at the same time the following errors appeared on my screen: 1) service stabaili trak 2) engine power is reduced slowly I was able to safely get the car up to 35 mph and get us home safe. I did some research and seems that this is a very well known issue with GMC so I contacted GMC and was basically given the runaround. I took the car to a GMC dear today and was told it was the fuel pump that needed replaced.....

At low idle or when backing up and accelerating vehicle the engine stalls. This typically occurs after driving car for 10-15 minutes. Engine light appears. It will continue to stall unless holding down brake & accelerator at same time. Stops stalling when speed increases, but stalls on low speeds & backing up continually. Code indicates camshaft adjuster sensor. First sensor replaced. Problem occurred again immediately after leaving garage. Second sensor replaced. Problem occurred once again! mechanic thinks it could be ground wiring issue is burning up the camshaft sensors. The car is not safe to drive.

After stopping at mailbox the low fuel illuminated, the fuel gauge indicated empty. The tank was half full prior to the 12 mile trip home from town. Not sure when the problem occurred, because it might have taken a few minutes to pump out 8 or 9 gallons of gas, however it was on this12 mile trip home. 6 miles of highway at 55 mph and 5 miles of paved county road at 30 mph and 1 mile of gravel road at 20 mph. After the low fuel indication the engine was stopped, fuel was added from a container, and when the engine was started the fuel streamed out on the ground. The vehicle was towed to a local repair facility, because it was closer than the dealer. Gas line and clamp were replaced. The mechanic indicated the plastic gas line and plastic clamp were hanging low, and no protective cove over it.

Terrain 6-cyl

I started out driving on highway road at approximately 5:45pm traffic was moderate, my speed was about 30-35 mph. All of a sudden I heard a clunk and then alarm ding from the dash as well as message "service stabiltrak" then "reduced engine power". I was unable to go any faster than 25mph. I drove in this mode for about 2 miles in traffic, when reaching open highway (no traffic) the vehicle would not shift by itself. I had to accelerate then let off the gas, tap pedal then the vehicle would shift. I was able to do this multiple times until reaching about 45mph. I pulled off into a neighborhood, shut vehicle off to see if this would reset something, it did not. The vehicle was in this state when I arrived at the dealership service department at approximately 6:05pm. Dealership logged following on service request: 5043 found code P228C ran diag could not duplicate problem fuel psi at spec raises to spec test drove on highway did not duplicate condition found no bull on condition test drive numerous time, could not duplicate concern. Miles out 5067.
