- Pasadena, MD, USA

My engine has had severe oil consumption issues. Within 2000 miles it will burn through roughly 4.5 quarts of oil. This has happened on multiple occasions, and I have taken it to the dealership multiple times for this issue.

- Marion, MD, USA

2013 GMC Terrain with 72K miles (about 5.5 years old at the time). In frigid temperatures (-15 degrees Fahrenheit), the vehicle rpms started fluctuating wildly while in idle, and would shut off entirely. The PCV port froze and lead to blowing out the rear main seal. Dealership told me it was not under warranty (despite the existing power train warranty and service bulletin 14882). Also the exhaust manifold was cracked (which should have been covered by the emissions warranty). Total repair was $2,800.

- Minneapolis, MN, USA

Car has started excessively using oil and ringing sound from engine. Roaring sound when it starts. I purchased car Sept '17, with 125K miles. Received a letter today May 8, 2020 saying this is an issue. Called GM says this service warranty has expired, but I just received letter today. Says previous owner probably received letter but that doesn't help current owner. I had previously visited a GM dealer 3 times and this was never mentioned to me. I want my repairs covered because someone dropped the ball and it wasn't me. It is not fair that I wasn't notified sooner I would have brought it in to be checked.

The car consumes oil so much you will stall out due to sensors pressure defect with the exhaust. I have spent so much money trying to fix, keep oil in it. It's not safe. It takes a full quart now every 500 to 700 miles and my car has 116K. It's been doing this for the 2 years I bought it. The stalling out with check engine indicates camshaft sensor but your just low on oil

- Winter Park, FL, USA

Started having a noise both cold and hot, had it inspected to find out the exchaust manifold is cracked broken in several areas and exchaust flex pipe is bad. Car has just over 100000 miles on it. These are around the area of the catalytic converts. GM says not under warranty I have been told this is a common problem with all 2.4 4 cylinder

- Gardner, KS, USA

My wife came home from grocery shopping, as we were emptying out the car we noticed a puddle of oil under the car. There was at least a quart of oil on the floor, I looked under the car and could see that it was the rear main seal on the engine. Then I went on the internet and found out that this is a problem on this particular engine of GM, and on most of the cars this happened to GM does not cover it. It ended up costing us $1142.44 to have it fixed. Since then I have twice taken off the intake, PCV tube and cleaned it out and found excessive moisture in them. This engine also has excessive oil consumption, there was a lawsuit against GM about this and our car is getting new rings installed. I'm hoping this will also solve the rear seal problem. This is a 2013 GMC Terrain, 2.4 liter engine.

- Wisconsin Rapids, WI, USA

I took vehicle in for a known oil consumption issue. The dealer check my oil and confirmed no active leaks. The next day a large oil leak appeared. The proximity of the two were purely coincidence. The dealer, after further review, uncovered a rear main seal failure due to a frozen PCV. This issue is documented in tsb 14882 however my vehicle's VIN is specifically excluded. Again my vehicle meets all of the requirements of tsb 14882. I am specifically looking to have the tsb expanded to include my vehicle and other similar vehicles.

I have a leaking rear main seal. This should be covered under GM bulletin 14882. I had a GM technician inspect the vehicle at glockners Chevrolet and GMC dealer in portsmouth, Ohio. He said the deal is leaking do to a clogged PCV valve. This is the very thing covered in the bulletin but they refuse to fix it because the VIN does not match. This is happening on numerous GM vehicles with this engine it should be covered under warranty. The temperature has been below freezing her for the last couple days. I drove the vehicle approximately 10 miles from work to the dealership.

- Lucasville, OH, USA

The car has oil consumption issues which is causing it to stall. My car stalled while driving in traffic which could very easily cause a bad accident GM is aware of the issue but won't fix it. I am already on my second engine do to this excessive oil consumption.

While driving on the highway, in the rear view mirror, I noticed a cloud of smoke. The vehicle then proceeded to lose acceleration, so I pulled over. Let me note that there was no previous warning light and that the oil was just changed at the end of Dec. 2019 (receipt available). Upon pulling over, the car flashed "oil pressure low - stop engine". the temperature outside was 13 and my two children where in the car; 4 and 2. not ideal conditions for the car to stop!!!. the car was towed to my home, by my insurance company. Upon examination, it was discovered that a rod went through the engine block. There was oil everywhere!! it was all over my driveway, (another note - this is the first time I have ever seen oil on my driveway from this vehicle), all over the back of my vehicle, and all over the underneath of the car. The next 24 hours we worked on finding a new engine. However, when I arrived home, there was a letter in the mail. Claim number 1900010 - berman et al V. GM. The claim stated that GM was to cover all expenses for repairs with a 2.4L engine, exhibiting engine oil consumption, due to piston ring wear. So the vehicle was then taken to a GM dealer; because the issue with the rod was determined by a jammed piston/lack of oil. After review, the dealer stated that the piston ring did not cause the rod to break. That the rear main seal went out. In one minute, no warning, the car that I have only had for three years and still owe on, blew! according to my research, there was a GM service bulletin 14482 in March 2015 for the exact same issue. I purchased my vehicle in Feb of 2017, clearly no idea. I think this is absolute bs that GM is not held accountable to repair all know issues in these vehicles! people spend their hard earned money and put their families in them with the expectations that they are purchasing a solid, safe vehicle!

On a cold 12 degree day on 1/19/2020 I was driving my 2013 GMC Terrain on a busy state highway doing the speed limit of 55 mph. Out of no where I began to smell the odor of burning oil and seen white smoke coming from the rear of my vehicle. As soon as I noticed it my car's gauges started coming on. The check engine light, a warning to for "service stabilitrak", then the warning for "engine power reduced". at the moment my car all the sudden shut off while driving down a major highway! there was no power steering and it was very hard for me steer my car into the parking lot of walmart and safely off the road. Once in the parking lot I got out of the car and checked my oil. Smoke is rolling out of the dipstick shaft. I check my oil weekly due to GM's oil consumption issues with the 2013 GMC Terrains and on 1/15/2020 the oil was at full, was of normal color and consistency when I fueled and checked it that day. So I was shocked to see that there was no oil on my dipstick and instead a milky brownish sludge on it. I sent my fiance to buy me 2 quarts of oil just to get it to the walmart service department so they could look at it since I was in the walmart parking lot. I added the oil drove it 100 yards to the service dept of walmart. The service man pulled it into the garage and then informed me a few minutes later that the rear main seal blew and oil was flowing out of it. It was not driveable so I had to have it towed to a GM dealer. The GM dealer called me this morning 1/21/2020 to inform me that the rear main seal blew due to moisture in the intake and a froze the PCV module and caused to much pressure to build up and blew the seal. The dealer quoted the repairs to be $2065.69 and informed me that the repairs are not covered under the GM service bulletin #14882 because my VIN number is not included in the service bulletin.

Rear engine seal blew according to bulletin 14882 March 2015 caused by a frozen PCV valve. Purchased the vehicle used from a GM dealership as a good used SUV. When reporting the problem, they said there was no bulletin, changed their mind, but said VIN disqualified it for repairs and said I had bad luck vehicle is unusable as it blows oil thru the seal when in operation

- Weyburn, MN, USA

Showed stability track. I was driving on the highway when it showed service stability trak then engine power reduced. It took my speed from a 65 to 35 in an instant causing me to almost crash. Then the car started to jerk as I tried to drive to find somewhere safe.

- Stone Mountain, GA, USA

My Terrain ran out of oil and had no leaking anywhere. Found out from the dealer that these vehicles have a huge problem where they are burning oil internally and need their pistons and rings replaced. Had to go in every 500 miles and have them check the oil. It was down every time I went in and they would have to add oil. I thought I was still under warranty and come to find out after finishing the oil consumption testing that I was not. The bill would have been over $5000 of which I am a single mother with a car payment for a car that is now junk. My car eventually died due to the oil problem and other common issues known to GMC. It is not fair

- South Saint Paul, MN, USA

Purchased car used from GMC dealer 88,706 miles. 1 previous owner thta purchased from GM dealer new, I purchased extra 100,000 warranty in addition. I drive about 10 miles total a day about 3 days a week to work, so I have not put many miles on it. 30 days after purchase when driving home from work got to driveway, car dumped large quantities of oil on driveway. No warning lights ever came on to indicate a problem. Diagnostics should have indicated pressure build-up. Car had hesitated a bit at the last stoplight before my house on the way home but not bad and only one time. Oil all over underside of vehicle. Towed to dealer, GM knows of the issue but my VIN is not on "the list" for the "service adjustment" not a recall but it should be.. nobody can say why. Will cover part but not all of the damage despite this being the result of a really poor engine design that is a "high oil consumption" vehicle. Is this the 70S? that should not even be a thing in 2019. The oil sludge in engine caused the PCV to freeze up in the cold temps and it blew out the rear main seal for the engine. They want $1300 from me to fix and GM is covering part of the cost. But if it is a design flaw and they knew about it, they should have fixed it before they sold it. Extended warranty will not cover this because they do not include the PCV. Likely will not ever cover anything with the engine since it is a design flaw and those are by definition pre-existing and high oil consumption that is not coming out on the ground is fouling up something. So my first payment is not even due yet and I already owe money to someone else and it is significant money that will not be easy to pay. If this had happened on the highway, I would have lost use of the vehicle at high speed and would likely have caused a crash.
