On December 19, 2020 I made a trip in my 2015 GMC Terrain. The temperature was 16 degrees. Upon arriving home, I noticed a large puddle of fresh oil coming from the Terrain. I contacted my local mechanic and he advised to bring it to his shop. I added two quarts of oil to the Terrain and I drove the vehicle to his garage. He said he would call me after he accessed the situation. Later that day, he called and said GM had a recall on 2012, 2013, & 2014 model Terrains with this engine but not the 2015. The problem he advised was in cold weather the condensation inthe valve cover froze, causing oil pressure to climb and exit out engine main rear seal. The same place as had happened on my Terrain. The GM recall was# 14882. I called GM and sent a lletter to them. I was assigned case I was advised to take my vehicle to burdick chevrole, cicero, NY. Upon contacting burdick Chevrolet, I was advised by a service manager that burdick does not rate other mechanics work. He also stated there was no way to remove the engine and take it apart as the correct parts were inside the engine. He stated they would not do that. I then contacted GM and advised the work was all done internal of the engine and it was not able to verify the work. I was then advised there was no way I would be reimbursed for any or all of the $1648 bill because the 2015 year was not on the recall 14882. On Wednesday, February 17, 2021 after running errands, upon returning home, I again observed a large oil puddle of oil in my driveway. I called my wife and advised her of the oil puddle. She advised she was at church, approx 4 miles away. I immediately drove there and observed more oil under the Terrain. There was no oil registering on the dip stick. I added 3 quarts of oil I drove the Terrain 3 miles to the mechanics shop again. He installed another rear engine main seal.

I had a brand new motor put in my car at 73547 miles and now at 124079 I am having the same issues. They told me that they won't pay for it because the 100,000 warranty is up. The new parts that I put in my car will have a warranty, but the new motor that I put in my car went under the old power train warranty. Check engine light came on while driving to dealership to get an oil change and I had it towed right away to fm dealer.

I have been having problems with my car sense I have owned it. From day one it started with my wheels rubbing and scrubbing when in motion.I called dealership had repairs done on it for the first 7 months.I reported the problem back then to you all. Then after 3 yrs I started to feel some hesitation when sitting or taking off.then the forth year my power steering light comes on had that fixed now my engine light keeps coming on car still having some hesitation on and off. I paid to have a diagnostic test done on it by the place that does my oil change and was told that my codes where off and they were reset but 5 days later my engine light is back on, ironically right after my five years limited warranty is over and my car only have 38,490 miles to this day and it is not yet paid for. This is ridiculous, I have spent the last 5 plus years of dealing with this new lemon and all I get is another bill add to the $528.02 a month I have to pay already. This car came highly recommended by the sales person and dealership and all I can see is that these cars are being push on hard working people that just want something reliable and its wrong. This car is frustrating and stressing me out, I cant rely on it to get me through 5 more years I thought more of the GMC product and I cant take anymore of this trying to make this bad situation better on my own. GMC needs to do something about these defective cars please.

I purchased a 2015 GMC Terrain from dealer ON12/18/2014. At approximately 700 miles, car would not start. Did nothing, no grinding, clicking just would not start. Had lights, radio, fan on heater. Call thornhill and car was towed there, they could not find the issue. Approximately 2 weeks later, another cold spell and car did the same. Was towed to thornhill and was there for several days. Would not start for them either, said they could not find the problem. Fast forward to today and car is still doing the same. When temperature gets to 10 or below, will not start.

- Phoenix, AZ, USA

The manifold and the catalytic converter is cracked and emitting hazardous carbon monoxide inside the cabin of the car. For close to 2 months my husband has been driving the car like this and we have taken it to 2 mechanics and finally found the cracks. My husband has been getting sick from the carbon monoxide. It is a blessing he is still alive. According to online google searches this is a well known issue in this vehicle. The smell is strong especially when he uses the remote starter and when the car is in motion and stationary.

While pulling into a parking spot very slow the vehicle accelerated and damaged car in front there are traction marks showing the sudden acceleration. The car would not stop until the ignition was turned off. Because the cars in front were hit I placed the car in park after the ignition was turned off.

I have a 2015 terrian sle. Around 57,000 miles my terrian started burning 2+ 2+quarts of oil in between oil changes with no apparent reason, I have always kept the oil changed before it got below 7%, after noticing the oil levels dropping fast I checked it everyday. The engine light came on with my last oil change, 2 weeks ago, showing 2 bad cam sensors P0010 and P0011. I went to my mechanic only to find out that the 2.4 motors have been littered with oil leaks, timing chain problems, cam sensor issue and stalling. I paid good money for this car and I am not pleased with the continuing motor problems from GMC. If the same problem that occurred on early models is still happening, why is there not recall? I am frustrated as I have only one vehicle and the out of pocket cost is ridiculous, especially when I'm being told it's cheaper to buy a new crate motor than fix what is wrong. I have always been a fan of GMC until this. It's no wonder why everyone has switched to foreign vehicles, the ones made in the us are so cheaply made and priced 3 times there value.

- Greenwich, NY, USA

Check engine light came on, took vehicle to the dealership the same day. Was told the timing chain needed to be replaced because it was stretched. I've had the same driving habits (distance, destinations, etc) for all 4.5 years that I've had the Terrain. I've had all but 2 oil changes completed at the dealership where I purchased my car originally. I've consistently had my oil changed every time my light comes on and says it needs to be done. I had my oil changed 5 days ago, on schedule and today my engine light comes on and I'm quoted at minimum $2K for a timing chain repair. I called another GMC dealership to get a quote on the work and was told more than $3000 would be expected. Every mechanic I've talked with (at each dealership) suggested this is a known issue with GMC Terrains, equinox's, traverse's.

Burning excessive amounts of oil.

- Tinley Park, IL, USA

Smelt something burning while driving. Car started bucking and jerking. I pulled into a parking lot and noticed a puddle of oil leaking out underneath my car. No check engine light or any notification that anything was wrong. Had it towed to dealership and they told me pvc froze up and blew out rear main seal. This is the 2nd time this has happened to us this year. We own another GMC (2013 equinox) and the exact same thing happened 2 weeks earlier with it. Frustrating that GMC is aware of this defect with their engines and not willing to issue a recall to correct it. We had to pay $2500 to fix the equinox. Luckily the Terrain is still under factory warranty but with both cars we were out of a vehicle for several days. Will it happen again"?"

THE CAR KEEPS STALLING WHEN TRYING TO ACCELERATE IN REVERSE OR DRIVE AND THE CHECK ENGINE LIGHT IS ON. THIS IS PROBLEM AS I AM READING UP ON THIS SO I BELIEVE THERE IS SOME KIND OF RECALL THAT NEEDS TO HAPPEN. THIS IS [XXX].

The engine light came on after an 3 days after oil change and begin to cut off when I would accelerate. I took it to carmax and they said it was a faulty sensor which was covered by the powertrain warranty. Carmax suggested I take the car to a GMC dealer for repair. I took the car to the GMC dealer, they repaired it and 1 1/2 weeks later the engine light came on and the car was cutting off again. I went to the GMC dealer a second time and they said, "they could not duplicate my concerns, there was no problem with the car, the engine light is not on and the car was driven for 10 minutes without any issues". after driving the car for 5 days, the engine light is on again and the car is stalling. I have to accelerate over 10 - 20 miles for the car to stay on. I know that something is wrong, I have been afraid to drive because with the car cuts off on me and no one has given a reason as to why. I do not want to get hit from behind. I drive the highway with a small child daily. I am concern that this issue is not being taken seriously. Something is wrong with the car!!!

- Upper Marlboro, MD, USA

I purchased my vehicle from a dealer in June 2018, and about a month of purchasing it my vehicle has been hesitating in acceleration, at first I didn't think anything of it, but it started getting worse. Two days ago when I was driving my vehicle in the downtown area (city streets), it was bucking a lot. When I got to my destination and restarted the vehicle, I put it in reverse and proceeded to drive back but the car shuddered and then shut off completely and the malfunction indicator lamp light came on (but it didn't stay on long). Today as I was driving it continued to jerk, especially when I was driving around 20 mph or below (which I had to do because of the school zones). My vehicle shut off again as I began to pull off from dropping my child off at school, which almost caused another parent to crash in the back of me. The only way I could keep the car from shutting off again is by accelerating on the gas above 20 mph.

While driving in stop and go traffic my car stalled, after restarting it it continued to turn off after acceleration and shuddered when miles to 20 miles an hour.
