The timing chain is run by oil pressure. This engine burns so much oil that I have put in 6quarts in 1 month. If not continually checking and adding oil the vehicle stalls in traffic.
The original Engine blew a piston rod and cracked my engine in the middle of the freeway, had to have vehicle towed to a shop and whole engine replaced with a new one. This could have caused a huge accident or even caught fire. I had no previous issue or light on the engine prior to this happening. Oil had been changer regularly, Tune ups, and any additional required maintenance, The Manufacturer has not wanted to take any responsibility or assist in compensating any of the cost. I have been fighting this for well over 2 years
The contact owns a 2011 GMC Terrain. The contact stated that while driving approximately 55 MPH, the stability track control warning light illuminated. The contact stated that the vehicle jerked and hesitated. The contact was able to coast to the side of the road and the vehicle stalled. The contact attempted to restart the vehicle 2-3 times before being able to proceed driving. The contact stated that while stopped at the next traffic light, the vehicle stalled again. The vehicle was restarted however, while driving the vehicle failed to exceed 40 MPH. The contact took the vehicle to a certified mechanic who stated that the spark plug and coil needed to be replaced. The vehicle was repaired however, the failure persisted. The contact took the vehicle to another certified mechanic who diagnosed that the spark plugs needed to be replaced because sensors within the vehicle, due to the excessive oil consumption, were clogging up the pistons. The vehicle was repaired however the failure persisted. The manufacturer was made aware of the failure and informed the contact that the vehicle was not included in a recall. The contact was referred to the dealer for assistance and a case was opened. The approximate failure mileage was 170,000.
Purchased this vehicle in November 2020 and 7 months later was coming home from a trip, there was a ticking noise got louder and faster and then a pop. Took vehicle to a mechanic spun bearings and rods and crankcase was completely dry There were no leaks or evidence of oil These vehicles are known to have excessive oil consumption. I believe that the blown engine was a direct result of oil consumption
Vehicle has been burning up to 3 quarts of oil every 1,500 miles. This has been an ongoing issue for years. In 2020 a GM dealer serviced/repaired the vehicle to correct the issue; the vehicle only had approximately 60,000 miles at the time. The issue returned around 20,000 miles after the repair. Neither an instrument panel light nor a OBDII code appears when the oil is low. When the oil is low the vehicle stalls when making a turn and also jitters and jerks while idling. I am put in a dangerous situation when the vehicle stalls (especially on the freeway service roads).

Timing chain either broke or jumped track while driving and car shut off while vehicle was in motion. Had to have it towed home and will not start ever since. I hear alot of complaint with this type of motor with oil use and timing with results of destroying engine completely and not having money to fix after paying alot of money for this vehicle. GM needs to take responsibility for their faulty 2.4l ecotec motor and issue a recall to those affected by this faulty engine. I was driving a busy street in my home town when the car just shut off while in motion. Lost all power to the vehicle and could have crashed or been hit or worse been seriously injured or fatally injured. Please take responsibility and fix the problems created by faulty equipment! I had purchased from used lot and broke down same month I bought it and has been sitting outside my house ever since over a year
The engine locked up while driving on the interstate rendering it inoperable and undrivable. There were no warning signs (ie. leaks, noises, overheating, etc.). The vehicle now needs an entirely new or used engine and is unrepairable.
Service stabilitrak pops up, engine goes into reduced power mode. Third time happening and dealership has done nothing to fix it besides charge me money. Car has 96k miles at this point and I-€™ve spent more money to fix it than it-€™s worth.
Due to a faulty PCV design my vehicle experienced a rear main seal failure. It was externally cold. The same as in bulletin 14882. GMC states that my vehicle is not covered.
Car randomly shuts off while driving it doesn't matter if I am on the highway or driving through the city, also engine power reduced mode. Throws random codes even after codes have been serviced. We have been dealing with this issue for close to 2 years with no resolve. After further investigation we have found there are multiple complaints of this exact issue.
My vehicle had been having to common oil consumption meaning I checked the oil every time I got fuel. This last time I went to check the oil level the dipstick was under so much pressure it shot twenty feet into the air when the hood opened. I then drove the vehicle from the gas station back home and this time took the oil fill cap off and when I turned the cap a quarter turn it blew off into the air followed by burning hot oil droplets and steam. When I run the vehicle for any amount of time the oil drain back system builds more pressure then the cooling system eventually causing the vehicle to stall under load such as when taking off from a stop. When the vehicle does stall it will take from 2-10 minuets to restart.
Excessive engine oil consumption about a quaker of oil every 2000 miles. This vehicle was bought from a non GMC as used certified with 145450 miles date 01/18/2019. By then then vehicles was classified as recall. With especial coverage warranty from GMC please see bulletin number 15285A. I reach out to GM customer engagement center of ca, but they refused to pay for diagnoses fees and repairs, quote the vehicle is over 120000. I had also made a complain to the better business bureau. I would like GMC pay for diagnoses and repairs to a certified local GMC dealership. Thank you for you help respectfully, customer

The contact owns a 2011 GMC Terrain. The contact stated that her vehicle would fail to start up after multiple attempts with an unknown engine warning light illuminated on the dashboard. Due to the failure, the contact had the vehicle towed to an independent mechanic who was unable to diagnose the failure but stated that the failure was likely caused by a defect inside the engine. Neither the dealer nor the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 115,497.
Purchased a 2011 GMC Terrain in may with 94K miles. W?hen change oiil light came on, took to a GMC dealer to have it serviced. Drove it home about 50 miles, parked in garage and 4 days later started it. Engine made a weird noise so I turned it off. Would not start again and had it towed to a local garage who tells me the timing chain broke and bent all the valve stems and damaged the heads. The vehicle is financed so I'm making payments on a worthless SUV that now needs a new engine at a cost of about 7500.00.
On 08/05/2020 I was sold this vehicle with a cracked manifold. Upon replacement of the manifold it was discovered that two manifold bolts were seared on the engine block side. After consulting my mechanic and another, I was advised that 1) to repair the engine has to be lifted as the space between the firewall and the engine is too small to make repairs without lifting the engine ( manufacture defect). Further, it was advised to me that completely sealing the manifold could lead to a fire in the catalytic converter because ' these engines run hot'. as I expressed that this vehicles 'antifreeze' level is not stable as I have experienced with other vehicles. In other words this vehicle burns up antifreeze quicker than I've seen occur in other vehicles. After researching the topic it was discovered by consumer reports that these vehicles have major defective engines with repairs to manifold being notorious. And to have to have the engine lifted each time is unreasonably costly. And I no longer feel safe driving this vehicle if a defective engine runs hot and there's a risk of fire. This is exacerbated by the fact of the tiny space between the engine and firewall within the vehicle.
Engine had to be replaced at 84,000 miles. States on docs at time of replacement timing chain and cam worn due to low oil.has warranty but for replacing due to 'oil consumption ' but service manager refuses to write that although he has stated it.GM refuses to help
