I purchased this in March of 2025. 2 or 3 weeks after I bought this I took it to an oil lube shop and they said there was not any oil on the.dip stick. Also I started noticing the car being jerky while driving and when shutting it off it sputters. I took it to Max motors, a GMC dealer for a diagnostic check because it uses a quart of oil a week. They told me the high pressure fuel pump is bad and the piston rings were no good. This was on the 18th of June. I had taken it to the dealer I bought it from and complained about the problems, but he wouldn't do anything about it . The warranty was good at that time. Max motors told me it would cost me about $5000 to fix it which I don't have. I read that there was a recall on these cars with a 2.4L engine for these problems.

Other years of this vehicle have recalls for the catalytic converter. My check engine came on and it said it could be that or the O2 sensors. O2 sensors have been replaced and the check engine light is back on.

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.

I'm having issues with my GMC Terrain when I start it. It always starts but it's like it keeps trying to start or is having issues getting enough fuel to get it to idle normal. Sometimes it only lasts a second or two and other times I have to push the gas pedal to get it to idle normally.

Driving one day on a beginning winter morning cr had ran perfectly fine and up-to-date on oil changes previously of six months of buying it then car started to automatically shut itself off every two minutes when driving down the road not knowing that the fuel fumes admitted from the engine do not have a large enough outlet causing my main oil seal to burst and blow my intake and there is no guarantee that this will not be fixed after getting repaired due to not being able to modify the original design.

Earlier this month while driving, our gmc terrain began shuddering while in line at a drive-through. A few days later while driving, it died at a stoplight, and when restarted, immediately displayed a warning that there was reduced power due to an oil issue. We were not due for an oil change. We had the vehicle towed to a body shop who informed us that it was leaking oil drastically and had a leak in the rear main seal. We were told it was due to the cold weather and that we were the third gmc terrain he had seen in 24 hours with the same issue. We had to take it to a larger shop for the repair work, which totalled $2,407.33 to repair. The shop said the pcv system froze and caused the rear main seal to blow out. They also told us there were multiple other gmc terrains with the same issue. I later learned that gmc had to issue a special coverage adjustment for the exact same issue for terrains from 2010-2013. This was the exact same issue. The special coverage notes that "gmc terrain vehicle may experience a frozen pcv system during cold weather operation. This may increase crankcase pressure leading to a rear seal oil leak." the part number they required to be replaced was the same part number we had replaced.
