My 2010 Terrain had been been intermittent dash warnings for “Service StabiliTrac” and “Engine Power Reduced” which would force the engine to reduce the speed itself down to about 30 MPH. After turning off car and restarting, warnings would go away. Yesterday, while driving on a secondary road, with no check engine light on, the engine stalled while traveling at approx 35 MPH. I was able to drop the vehicle into neutral and coast onto a side street, while also attempting to restart the engine. I was able to pull over without causing an accident. After letting the car sit for a few minutes I attempted to restart the engine, but only got a strange noise from the area of the upper cylinders. At his point the check engine light was now on. While waiting for a tow truck, and independent mechanic pulled up to ask if I needed help. After listening to the noice from the upper engine he asked if he could get tools and look in the engine. I said yes. He quickly pulled parts off the upper engine and opened and removed the upper cylinder cover. This revealed that the timing chain had no tension, as well as shards of shattered plastic all over the place, in and around the upper cylinders. After pointing this out he put everything back together and suggested I contact the dealership I got the vehicle from, which I have done already. He then stated that it appears that the engine would need to be replaced or rebuilt, due to catastrophic engine failure. He said my quick thinking of putting the vehicle into neutral probably avoided causing an accident and allowed me to get myself to a safe spot before stopping the vehicle. He also stated that this particular GM motor is known for catastrophic failure, which GM has failed or refused to acknowledge

I bought my 2010 GMC Terrain SLE at 160,000. It had a rough start up but the dealer said it was because it was an older car and been sitting for a while. The rough start up never stopped even after replacing the catalytic converter because of code P0420. The mechanic informed of this specific vehicle oil composition so I was consistently checking the oil. A month after the NEW catalytic converter was installed. I stalled out on the interstate with traffic going 65 mph minimum, the wheel locked and I was almost rear ended. I take the vehicle to an automotive shop and I need a new timing chain with numerous new codes. P0325 P0326 P0327 P0016 P0017 P0014.

Vehicle has consistently run low/out of oil, and oil would need to be added weekly to maintain levels. After asking/checking for recalls, nothing was found. Two weeks ago the vehicle kept stalling when driving. Mechanic found that timing chain had stretched causing engine damage. This is the same as reported in the federal safety agency #10053269.

I was getting gas, fiiled up, when I got back into car, didn't want to start, really had to hit gas pedal, very scary, that happened 3 times after getting gas, another time I was at stop light, and it just stalled, engine completely stopped, hard start up again, so I decided for safety reasons taking it to dealership, it's still there as of 11/20/2017, but wanted to get this out there, I think maybe this is ongoing issue with certain models of gmc, and feel maybe it will be a recall issue if enough people report issues as such as these. I thank god I wasn't driving and this happened, def a safety concern gmc needs to address.

I I changed it. It stalled repeatedly and we had it repaired recently. We also had the oil checked and replaced so gm could track the oil consumption. Unfortunately a month later the car would not start sitting in the driveway, so we had it towed in to a gm dealer. They said the timing chain is busted and they need to pull the engine because there is metal in the oil pan so our oil test is worthless. The mechanic said not changing the oil or low oil levels may have caused the timing chain problem. The estimated cost to fix the current problem is at least $2,300. I'm going to contact a lawyer and see what can be done because this car should have been recalled.
