GMC Terrain 2012 — Reported problems

My car has started stalling and dying when i slow down, take off or when idling. No power when accelerated, and the smell of exhaust comes into my car. I was making a turn from a red light and my car spit, sputtered, and died right in the middle of the busy intersection. I was almost hit from the rear and another car had to go into on coming traffic to avoid T boning me. I took it to 2 different places to get a diagnosis reading and both places said it was a catalyst problem, and I was told that there was a recall about that because of engine oil clogging it up. My car has been using more oil than usual here lately and im guessing thats why. Now, im afraid to drive anywhere because I don't feel like it safe and the fact that my car doesn't run good enough to drive. I was told by more than 1 person that knows mechanics, that its a issue with the catalyst and that it had a recall on it but I never received one. This is a very concerning safety issue, and one that needs immediate attention before someone gets badly hurt (or worse) because of a bad car part . My car is literally just a lawn ornament now until I can get this issue resolved. I need my car to make a living and support my family. PLEASE, get the recall letters out and get this fixed before someone loses a life.

The engine blew. This was already the 2nd engine in the car. Oil consumption. Metal in the oil. No signs. Needs new engine

The oil is depleting every month from the vehicle. Every 2-3 weeks I have to put oil in the vehicle because the oil is being absorbed. Is there a recall on this problem.

1. The engine suddenly lost power while driving during evening rush hour and the vehicle would no longer accelerate. 2. Because the vehicle could not maintain speed, I was unable to keep up with traffic, creating a serious safety hazard that could have resulted in a major accident. 3. The vehicle has been inspected by an independent service center for diagnosis. 4. During the incident, the “Engine Power Reduced” warning indicator illuminated just before the loss of power occurred. 5. As the vehicle slowed and came to a complete stop at an intersection, it remained unresponsive. When the traffic light turned green, the vehicle would not accelerate at all.

Liftgate automatically closing and failure to remain open causing a safety hazard for anyone standing at the liftgate.

GMC Consumer Relations Subject: Structural Undercarriage Safety Defect – 2012 GMC Terrain SLE Vehicle Information: Year/Make/Model: 2012 GMC Terrain SLE VIN: [XXX] Mileage at Purchase: 148,305 Date of Purchase: [XXX] Location: Rochester, New York I am filing a complaint regarding a severe undercarriage safety defect in my 2012 GMC Terrain SLE. The rear undercarriage of this vehicle shows heavy structural corrosion on suspension brackets and mounts. The condition produces clanging noises during normal driving, and an independent licensed mechanic has refused to work on the vehicle because the suspension integrity is unsafe. When I returned the vehicle to the dealer, I observed additional brackets being attached under the rear subframe area, suggesting reinforcement of compromised structural points. This confirms that the corrosion directly affects suspension geometry, alignment, and stability. This corrosion is not cosmetic. It is advanced structural deterioration affecting the mounting points for trailing arms and lateral links. These components are critical to safe turning, stability, and control. The corrosion compromises the ability of the suspension to keep the wheels aligned, creating serious risks of loss of control or wheel separation. What makes this more alarming is that the vehicle passed a New York State safety inspection on 07/13/2025, yet within days a mechanic refused to perform unrelated service because of the undercarriage condition. This raises questions not only about inspection validity, but also about the underlying durability and corrosion.

The contact owns a 2012 GMC Terrain. The contact stated that while the vehicle was parked in the garage, the front driver's side air bag unexpectedly deployed without an impact to the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was 148,116.

I have excessive oil consumption. I noticed the issue after getting my 3000-mile oil change. The technician said I only had 1 quart of oil, which I thought was extremely low. Every 2000 miles, my oil dipstick reports abnormally low oil levels. I am concerned that when I go on an extended road trip, I will have engine issues that will leave me and my family stranded on the side of the road. The GM technician started tracking my oil consumption. He said he was doing that to prove to GM that they owe me a new engine. I didn't understand what he meant until I saw a lawsuit my vehicle was part of.

Car burns oil bad . Got an oil change and it only took 12 days to go dry with no oil

The contact owns a 2012 GMC Terrain. The contact stated that while attempting to reverse out of a parking space, upon putting shifting into reverse, the rearview camera screen turned off. The contact stated that the display screen went blank, and due to the failure, the vehicle bumped another vehicle that was also reversing. There was no warning light illuminated. The contact stated that it was a minor impact and that there was no cosmetic damage to either vehicle. The Police was not called. There were no injuries reported. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the center console display was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 68,000.

Issues with the passenger side seatbelt not pulling to lock. It's jammed off and on. Doesn't work.

I think the manifold on GMC Terrain need to be on a recall because mine already cracked.

Evap emission control leak detected As the check engine light comes on, when hooking a computer up to the car for a scan it pulls a code stating there is an evap leak. The gas cap has been replaced along with a sensor and no gas is seen leaking but you can smell gas vapors when the car is running and fuel mileage is terrible. Also the stabilitrak has been an underlying issue since owning the vehicle

It appears the timing chain is bad. The vehicle only has 84000 miles and currently the engine turns off and you just coast to a stop in the middle of driving.

The contact owns a 2012 GMC Terrain. The contact stated while driving at an undisclosed speed, the vehicle stalled with no warning light illuminated.

The contact was informed that the engine control module and the camshaft actuator solenoid were replaced. The vehicle was repaired however, the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 191,843.

I have a 2012 GMC Terrain!! I am the 2nd owner of this vehicle purchased in 2014-2015 there is an engine oil consumption issue with this vehicle that I have to add 2 quarts of oil every week!!! I have not been notified of any recalls or any information from GM in regards to the issue!!! Took it to dealer to have it checked and got told it’ll cost me over 5000 for the repairs!!! Is GM or will GM take care of this issue

Took vehicle into dealer for a recall on October 17, 2023 with the recall being [Primary]: RECALL : C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS: C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS. The dealership did an excellent job on the work providing a video to show work being done. Now this month of April, I received another check engine light stating the P0013 code stands for “Exhaust “B” Camshaft Position Actuator Circuit/Open (Bank 1).” There is not a recall from the manufacturer but according to dealership they've received a bulletin in regards to this issue. According to the dealership it will cost in excess of $500 to repair. Absolutely not true. There are a thousand videos on what causes this and even how to repair it from the same mechanics that work within these dealerships. This issue is a safety issue because if not repaired it causes damage to your engine. This code lets you know that you will start experiencing loss of power, trouble starting your vehicle, the stalling/picking up speed all at the same time. Some of these issues have been caused from the issue of the oil consumption problem associated with the Terrain's.

hello i'm writing this letter to inform you about my 2012 Terrian i have had nothing but problems with the motor and now the muffler system i have had all recalls done on this and GM is well aware of this problem i have a dealer ship to replace the timing in this motor and still uses oil and still have all the problems after the recalls have been fixed now they want me to pay over $3,000 to have new catalytic converters fixed on it now after paying $2800 for a new timing seems to me GM likes to fix the cheap stuff on these cars and make customers pay for the expensive parts must people can't afford this and junk the vehicle i will not i'm going to fight for what is right the dealer ship even told me when i took it back in to see what the code was for that GM is well aware of it and not worth putting the money into the car this is not right for customers to spend this kind of money GM needs to handle this.

My vehicle is 2012 GMC Terrain. Oil changes on my vehicle we kept up and i had no major issues with this vehicle. I had an oil change done about a month before i went to start my car and all the lights came on and my car would rumble and wouldn't stay started and was longer drivable. After towing it a service shop they stated the following: The timing chains are damaged, skipped teeth, metal debris found in oil and screen of intake and exhaust camshaft solenoids due to many oil leaks coming form engine and serious internal issues w/engine we recommend replacing the engine. Est cost, 11,061. I had no reason to think my car was in any trouble, as it was driving fine with no problems. I received no such recall letter or phone call and no mention from the dealership i bought the car from back in 2018 that this was an issue or that it was "taken care of" if I had i wouldn't have paid over $20,000. into my car. Reading several complaints online about this exact issue is all new to me. Knowing i could have been driving a vehicle and it could have started a fire in my engine is crazy to think. Because I may have been driving a car with a serious recall on it. I am at a loss right now, financially i am screwed.

hello i'm writing you today in concern of my 2012 chevy terrian i have had all the recalls done on this car and still have problems with the motor this car has a new timing chain in it and still uses oil the recall for the o2 sensors i have had fixed now the light is back on and now the complete system is bad from my understanding this is a well known problem with these cars when you spend that kind of money on a vehicle you wouldn't think there would be the same problem that was just fixed i'm writing you now my engine light is on again and it's the o2 sensor that i had just replaced under the recall i don't feel i should have to pay to have this known problem fixed now.

After I purchased the vehicle in 2 months I was losing oil. I continued to add oil as needed even after oil changes. About 1 year after purchase while traveling the engine just blew. Causing me to swerve out of traffic until I could find a place to stop. The result a blown engine which cost 4000 to rebuild

Will like car facts

My 4 cyl. AWD GMC Terrain has had excessive oil use which caused premature failure of the timing chain, loss of power/compression, blown engine, damage to exhaust manifold, cellinoids, and melted the catalytic converter. Its was a road safety, poor emissions due to failed catalytic converter. Headlights are too bright for oncoming traffic at night. Another road & safety hazard. Auto warranty is refusing to cover parts listed above caused by the timing chain and excessive oil consumption problems.

My lift gate has been failing since i bought it used from a local dealership. It's closed down on my mom's leg when she was situating luggage that she'd put in. It has tried closing on myself as well each time i opened it(4×) & when I tried to stop it by pushing up on it, it only forces itself down not up. This is very dangerous & had an old recall from GM motors due to the struts in the lift gate was faulty & made by stabilize whom had numerous lawsuits from other manufacturers due to injuries & deaths. The dealership refuses to fix it for free even though they knew the issue with it cause it was brought to their attention by their detail guy whom had it close on him as well. This a is major issue that needs addressed asap. And not at the expense of the owners but the manufacturers & dealerships that knowingly sell these autos that can be dangerous.

Wiper motor went out on me no warning

Drive side frame is rotted out which has allowed rear driver side control arm for the wheel to freely move. The passenger side is completely fine. Contacted gm and was told it has to be taken to a dealer to be diagnosed. It’s easy to see the issue I have pictures that can be provided. This car should not be rotted out frame was perfect 8 years ago with no rust and has been washed twice a week during winter to remove salt with undercarriage car wash.

Windshield wipers quit working. I can hear something, but blades don't move. I see the 2014-15 have a recall.

The timing chain is failing on my 2012 GMC Terrain. It’s dangerous to drive and it started without warning (to me). It’s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? Many thanks.

The display screen of GPS/Radio is blackout combined intermittent control button illuminating light went off( include emergency, A/C control), backup camera stopped working, turning signal lost click sound. Safety concern: 1. Emergency and A/C control buttons lost illuminating light(Causing night driving difficult.). 2. AC vent the temperature control lost visual status cause distraction of normal driving. 3. Lost Backup camera function which is supposed to be an assisted safety feature. 4. Lost turning signal click sound which leads to missing alert of turning signal malfunction. 5. Complete audio loss create unsafe for long trip driving. 6. GM doesn't provide genuine replacement part. This problem started from 2018 till now. I've contacted GM with no meaningful resolution. I visited the dealer and the only thing they could do is replace non guaranteed refurbished head unit with hefty price. I did some research online and found there are a lot of same problems happened to this vehicle and similar models of GM. After driving this vehicle for several years without incurring any accident, I realized that the losses of the some vital control functions and safety alert are actually very serious concerns and should be addressed and resolved by GM.

When I stop at the light my car shake and rocks, then the car goes into limp mode. Where the stabilitrack comes on and the engine goes into reduced mode. And I can't go over 30mps. When this happened on the freeway is the most dangerous and scary feeling ever. I've got So many new parts and put over 3,000 into the car and it still has this issue. I've been do several different mechanics and nobody can figure out what's wrong. Gm needs to look into this, it's so many forums going on for this issue.

Ball joint for wiper assembly just "pops off" while in use causing wipers to stop working. I have taken vehicle apart, fixed the issue ( reconnecting the ball joint) and issue happens again. I understand the vehicle is from 2012, but uses same part 2010-2017, which is currently a recall on 2013-2015 models. First occurrence of this issue was July 02, 2019. I brought to GMC dealer, they said they were out of the part. Since then I've not had the issue until today March 14, 2023 where I almost hit another car, due to it popping off and stopped working while in motion.

I was driving in the dark at 5 am with my 2 year old son in the down pour rain and my wipers stopped working but the motor was still running
