This vehicle has major engine problems. It stalls, bucks shakes violently when stopping at a traffic light or stop sign. It does this when put in reverse. It was so bad that the engine and transmission was replaced. 2 days after that it was doing the exact same thing. It's a defect in the engine design that I found out between 2010 and 2015 GMC terrains. This thing stalls on the highway, loses power. Goes into reduced power mode check engine light comes on. Burns oil like it's drinking it. This thing is going to get somebody killed. I did research and found at least 50 other people complain about the exact same thing. People were changing sensors and everything else on the engine with no help whatsoever. It's a defect in GMC's engine design on these models.

I bought my used 2014 GMC Terrain in September of 2021 from a GMC dealership. Not long after owning it, I checked the dipstick and the oil was too low to register. I then take it to the dealership for investigation where they tell me we need to perform an oil consumption test. After the first check in after 1,000 miles they said it was within its normal consumption levels and to come back in another thousand miles. A few days later I decided to check the dipstick again for myself to see the oil level was below the dipstick again. Since then I took it to another dealership where they once again performed an oil consumption test and said that my car did have a problem as it was consuming around 2 quarts for every 1,500 miles. Not wanting to pay exorbitant prices for them to repair it I have just been checking the oil level every 500 miles and filling it back up. I have heard numerous problems that occur when the oil gets too low such as permanent engine damage, stalling, and more. I am aware of this issue but many are not and it could cause very serious accidents for those who also have this problem

I have had the same oil consumption and car stalling problems as everyone else. When the oil gets low after a few hundred miles, it stalls out when starting from a stopped position. It goes through a quart of oil at less than 1,000 miles. Add me to the list that says they need to recall the 2014 Terrains since they have the same problem as the 2011 to 2013 Terrains that were recalled.

February 3, 2022 I noticed a slight stutter in my 2014 GMC Terrain (approximately 111,346 miles) when accelerating after stopping at a stop sign. When stopped at the next stop sign the stutter happened again, and I aborted an attempt to make a left hand turn onto a 2 lane highway. Once the highway was safe again to make a left turn I attempted the turn, and the car died in the middle of the highway. There were no check engine lights, or other warning lights on at the time of the stutter, or when the car died. I was able to restart the car (no warning lights once restarted) and continue driving to my destination to drop my child off at school, and return home. Upon arriving home I researched the issue, and found similar complaints regarding the same issue of 2014 Terrains either stalling while driving, or having complete engine failure while traveling highway speeds. Upon further research I also found numerous complaints regarding unusual oil consumption. In 5 days I added 5 qts of oil, and took it to a repair shop February 10, 2022 where they added 4 quarts of oil and diagnosed a rear main seal (again no check engine light, or oil pressurewarning light). Bottom of my car is currently covered in oil from the massive leak. I purchased the vehicle used, and have changed the oil on the recommended schedule with 5-30 synthetic blend oil.

Around 76k miles the vehicle started to stall, the engine completely stopped while in drive. The vehicle was burning oil and had terrible gas milage prior to stalling incidents. The first time it stalled was at an intersection with a traffic light, when we went to slow down the engine completely shut down. My infant daughter was in the car with me and it was terrifying. We would have been hit had the light not been turning red. After that we recognized that it typically stalled after starting the car and attempting to accelerate. At times it happened when pulling out of a parking lot onto a busy street and I would loose engine power. This was extremely scary due to not being able to get out of the way of oncoming traffic. I had to put my flashers on and roll to the side of the road where I could restart the car. The engine ran really loud and rough when the issue first started and even after repairs the engine is still loud when first starting from cold. After time the issue persisted and I noticed that after the first start and stall if I revved the engined hard it did not stall a second or third time. Prior to that there were times the vehicle stalled 2-3 times after first start. The first time I took it to a garage (79k) there was a check engine light on and they diagnosed a sensor that needed to be changed. The problem persisted after the sensor was changed. I contacted another local garage who said there are known engine issues with this make and model and they wouldn't touch it and suggested taking it to the dealer. The dealer said they are familiar with this issue and the engine needed to be rebuilt for $4500. This was quite a shock given the car only had 88k miles on it at the time we contacted the dealer. After the dealer repairs the engine no longer stalls. Recalls on this model only go through 2013. The date on my radio resets to October 13, 2013 when the battery is disconnected so it seems this issue is persisting in models not included in the lawsuit.
