Engine Shut Off Without Warning problems of the 2011 GMC Terrain

I was driving and my vehicle totally shut down. I had stopped to make a right hand turn. As soon as my turn was complete; it shut down. And would not restart I had to have it towed home. Previosly to this it would stall, and I would have to put it in nuetral to restart it. Then next day I had it towed to be seviced thinking it was the fuel pump. Got the call from mechanic telling me the problem is the timing chain broke and has caused serious engine damage. . . . . . Piston and valves torn all up. . . . . Obviously a huge problem with this vehicle model. I have read so many complaints about this issue in regards to this model. My Terrain only has a little over 100,000 miles on it. I have to pay $5,000. To have a rebuilt motor put in it. . . . . . Shame on GMC for putting so many of us customers in danger of being seriously injured. And causing us to pay for this problem; that this vehicle obviously has. I'm sure the mechanic shops love seeing us towing our junk Terrains come rolling in. They are making some serious money on rebuilding motors that should never be having these problems. . . . Come on with recalls please. . . I can't afford this extra expense.

Abs light is on even after fixing the supposed problem. System stabilitrak constantly on. Excessive use of oil. 2 to 3 quartz every 2 weeks. Reduced engine power comes up on dash and no matter how fast I am going (15 mph or 80 mph on a highway) it doesnt matter my car will slow down or just shut off. Also happens when I have to hit braked hard, slow down or accelerate from a stopped position. I am also using a lot of gas.

Tl the contact owns a 2011 GMC Terrain. While driving approximately 25 mph, the vehicle shut down and the reduced engine power indicator illuminated. The dealer and manufacturer were not made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 83,000.

While driving message read reduced engine power lost all power could not control the steering wheel! then the car shut down and continued to roll down the highway . Almost got hit by other cars from behind. Very frightening for me I almost got a panic attack. I managed to stop the car on the shoulder of the road with half of the car still blocking other cars . Car will not start. The battery is new . I have done research on social media and there's thousands of gm customers who have or are facing the same issues. Is this another cover up by gm that's continuously ignoring this problem and the consumers are paying thousands of dollars in this repair. I was told I need repairs that will cost $4000 dollars on a 2011 GMC Terrain car I got a year ago. This is ridiculous. Who is fighting for the consumers?.

The engine or fuel system show a severe malfunction. When at a stop light, the rpm's drop so much that it shuts down sometimes, some others, it barely stays on. I called the dealership and told me that it was not a warranty covered repair and that I had to pay for the diagnostic plus whatever was wrong to repair (parts and/or labor). All of the sudden, now the "stability trac" check light goes on an off without apparent cause. I feel like I'm driving a vehicle from the 1950's. It's a great looking comfortable SUV, but very disappointed with performance and fuel consumption.
