general problems of the 2014 GMC Terrain - part 2

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.

My 2014 GMC Terrain- while driving on freeway white smoke was coming out exhuast - then a low power warning came on- I pulled off freeway to side road where the engine oil light and stop engine came on- it was towed - because of the rear main seal- it caused car to break down- several other have had this issue - there was a class action law suite for the 2010-2013- now we need 2014 and 2015 to be next- car has 80. 000 miles- engine should not be blown- I was told that bc there was over 80000 miles- nothing covered- and that my car was not made in the facitly that the problem occurred in? are they not made the same/ same parts?.

Moved car to shovel drive way. Went to move it back and my car wouldn’t start. Garage says it is the ecm garage says gm has a hold on the sale/install on f this part as there is a known issue involving all unit including my vehicle and newer. The only recall currently is for exams for 2018 GMC Terrain ecm. My car will sit at the garage indefinitely.

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.

All service was always performed on my car on schedule. I was driving from work to school to pick up the kids, and my car went silent and I had no control. Almost all the oil was gone and the timing chain had broke and destroyed my motor. I had just had the oil changed a few weeks before. Now it needs a new motor.

I purchased this vehicle in October. Had the oil changed end of October. Yesterday took it in to the shop and they told me there was no oil in it, that it burned through 5 quarts of oil in two and a half months! I search this problem and found out! that there was a class action lawsuit for 2010-2013 that was settled for this problem!!!! not the 2014. Please issue a recall the problem is the same with the 2014. I cannot afford to put a new motor in this…the mechanic said I got lucky it didn’t blow up. He said that is the only fix that can fix the burning of the oil.

The contact owns a 2014 GMC Terrain. The contact’s husband stated while driving 10 mph, the vehicle leaked all of the oil out of the engine. The contact stated that the low oil pressure warning light was illuminated. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the rear oil seal needed to be replaced. The vehicle was repaired however, the failure persisted. The manufacturer was informed of the failure, but no assistance was provided. The failure mileage was approximately 89,000.

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.

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.

On line it said that this vehicle was having problems with the timing chain which could break when driving causing damage to motor or worse yet loss of control. I had it to garage and they said the ticking noise is the timing chain. Is GMC recalling the vehicles for this?.

My check engine light would come on, the oil dipstick would be dry and multiple misfire codes happened. This went on multiple times because of oil consumption. I would pull over and call aaa to tow my car. Driving while the oil is low is damaging parts in my car, causing loss of power and can cause a fire. I have to check my oil dipstick every week to make sure it has enough oil before I drive. I'm adding oil multiple times before an oil change is needed. The oil consumption was confirmed by a GMC dealer and documented. GMC dealer inspected my car. The oil consumption started 08/10/21 and was documented again on 11/19/21 with GMC tech stating what's wrong. Oil consumption is going on with multiple GMC vehicles and GMC has not done a recall and they absolutely should have a recall.

I need my whole engine replaced due, to common oil issues with the vehicle. Thus, it has caused fuel propulsion issues, and engine trains breaking.

My GMC Terrain makes a clunking noise under the hood when I accelerate and go into a lower gear. Does it mostly going up hills but also even on flat road.

Car is burning oil excessively and the timing chain is loose putting the vehicle is reduced power mode. The timing chain was replaced at 40,000 miles and now it needs to be replaced again and the car only has 87,000 miles. I bought it with 70,000 miles on it. Someone needs to do a recall on these engines.

The timing chain broke while I was driving.

The contact owns a 2014 GMC Terrain. The contact stated while driving at various speeds, the vehicle hesitated while depressing the accelerator. The service engine warning light was illuminated. The contact had taken the vehicle to several independent mechanics and was informed that the catalytic converter needed to be replaced. The contact then took the vehicle to the dealer and it was confirmed that the catalytic converter was defective and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 140,000.

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.

For the last 6 months my vehicle has excessive oil consumption 1/4 to 1/2 quart of oil every week. When it starts up it sounds like a diesel engine. In 2019 it did the same using about a 1/2 quart every 3 weeks. We have kept an eye on it ever since as over time it has increased oil consumption and just recently found out this is a problem for many others as well. We have always kept the oil changed when due per mileage sticker and vehicle oil life indicator.

Camshaft actuator malfunction causing vechile to shut down -very unsafe. Have been told by dealer this happens to all GMC Terrains and once fixed it will happen again - should not have to pay for something that is your problem.

Driving between 40-45mgh and stabilitrak failure service and abs failure light comes on. At every bump the service lights goes on and off. Then on a smooth service the stabilitrak lights comes on until I get home. With the collision warning turned on the car also and almost frequently tends to brake on its own while driving. But here's the real problem this 2014 GMC Terrain denali car is not on the �recall� list - why? seems it's from the same car manufacturer with same issues, shouldn't it be on the same recall list.

Tl-the contact owns a 2014 GMC Terrain. The contact stated that while driving at 40 mph, oil pressure warning light illuminated. The contact veered to the shoulder of the road got out the vehicle looked down where the hood is and seen the oil flowing out the engine. Triple-a was contacted and towed the vehicle to the dealer reichard Chevrolet: 575 arlington rd, brookville, OH 45309(937) 833-4011 where it was diagnosed that the engine main seal fractured and needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and made aware of the failure informed the contact that the extended warranties expired but they would offer $100 certification for repairs. The failure mileage was approximately 109,000. Ck.

I been changing my oil every 2000 miles however engine oil stays low; several sensor malfunctioned stating that the throttle position sensor, camshaft sensor, and crankshaft sensor was bad but in fact it was the engine. While at the repair shop to replace the camshaft sensor because the vehicle wouldn't start I learned that the engine locked and had to be replaced the engine due to low to no oil in the engine but in fact I got the oil change 2-3 months ago.

The car at 80k had its engine repaired under warranty for a bad deal which then ruined pistons and etc. At 155k it did the same and powered down on the side of the road with engine issues. I was driving on the road when this happened leaving me on a curve and the engine fuming and oil pouring out under neath.

I have a 2014 GMC Terrain with 102000 approximately. I received notice that I needed to change my oil. I went about 50 miles and started making a bubbly sound. When I went to get my oil changed, the mechanic said it was so long they couldn't get some on the dip stick. I left the mechanic with 100% of oil and just drove to san antonio and it is down to 98 %. I have a 2008 chevy trailblazer and have never had this problem.

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.

My car completely shut down while turning a corner (powered off). I almost hit a tree because I was unable to turn the steering wheel. Once I applied the brake and put it into park, I was able to restart it with no apparent issue.

Was driving an car cut off an will not start was driving on a city sreet.

Was driving on a state highway. Upon taking off from a stoplight, a harsh noise came from the engine, followed by a loss of power and oil. Car was towed to a shop, was told metal shavings are in the pan anf the engine would need replacing.

My car engine light comes on and the car keeps cutting off when I stop or when I get ready to drive. I took my car to the mechanic and he is telling me is the camshaft that these cars have alot of complaints for this. My car has less than 52k miles. I don't drive my car a lot. This is horrible that this is happening so soon.

2 and a 1/2 months after I bought my 2014 GMC Terrain used. It had no oil in it. I had to put pretty much a whole new engine in that cost me $5000.

For the past two months there has been a steady increase in carbon monoxide leak in the cabin of my vehicle. Initially I thought it was something that will go away but for some months now the leak has been growing. I have to drive with my windows down just to be able to breathe in my vehicle. This vehicle have not had an accident or damage. I have kept a clean maintenance record of this vehicle. I am a disabled veteran with tbi and ptsd and the fumes from the carbon monoxide in my vehicle is causing my migraines to intensify. Please help me resolve this issue as soon as possible before I die behind the wheel one day driving in my vehicle. As soon as I turn the vehicle on, the carbon monoxide fills the cabin up.

3 years old now and still getting around 10mpg and from the first day I got it in 2014 the drive shaft is rusted and was told by the dealer that nothing is wrong with the car. I also notice that when driving at night that the head lights are not made to see street name signs I have to use the high beams to see if I have the right street when looking for the place I have to go.

I was driving my Terrain yesterday, and went to adjust my heater vent and when I bumped my ignition key, it went into the accessory position, shutting off the engine and power steering.

Drove my 2014 6 cylinder GMC Terrain with engine oil level filled for 4 cylinder before discovery of the dangerous oil level. GMC in detroit was notified in certified letter and local dealer was notified. Neither responded in writing as I requested.

I was driving home after work around 7pm going about 45-50 mph and all of a sudden my car began slowing down and I could not accelerate. This is when I realized that my car had shut off while driving. Also, my headlights turned off which I noticed immediately since it was dark outside, the computer system shut down, gas indicator went to e and the engine turned off. I was able to coast over to the right lane and as the car was slowing down my steering wheel began to lock up. Once I was fully pulled over from the traffic, I braked and put the car into park. I waited a few minutes to catch my breath on what had just happened because this could have caused a bad accident if it were more traffic. Since I was pulled over I thought I would try to restart my car. Before I restarted it, I noticed that my key ignition was still in the on position so I turned it back to take the key out and then immediately placed it back in and turned it to successfully restart the car. This is the first time that this has happened in this car. I've had it since Dec. 2013 and have a little over 15k miles. I will be contacting the GMC dealership regarding this issue since I did not see any recalls addressing this issue.
