The contact owns a 2014 GMC Terrain. The contact stated that the oil gauge failed to display when the oil level was low. The contact heard a rattling noise coming from underneath the hood of the vehicle. The check engine warning light was illuminated. The contact stated that oil had to be added between 800 - 1,000 miles. The contact took the vehicle to a certified mechanic who replaced the PCV valve however, the failure persisted. The vehicle then displayed a timing chain code. The contact took the vehicle to two different dealers who diagnosed the vehicle and determined that the piston rings had failed. The contact was informed that the timing chain, pistons, and pistons rings needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 68,500.
2014 GMC Terrain engine complaints
Page 3 of 5: complaints 41 to 70 of 130, newest first, as owners wrote them.
Issue of timing chain failure. After 100,000 miles of use during which time no engine warning lights of any kind were observed the timing chain broke disabling the vehicle & resulting in dealer repair estimates upwards of $10,000.
My car had been needing at least 2quarts of oil in between oil changes which I have done every 3000 miles. The timing chain is bad which is caused by excessive oil consumption. The service power steering and stability track light comes on it its messing with the transmission until I disconnect the battery and reset it, and it also leaked inside my glove an f the passenger floorboards
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.
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
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.
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.
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.
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.
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?
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 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.
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.
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?
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.
The engine is burning oil. Losing oil quickly and no leak. Wiper motor shot. 90k miles on vehicle
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.
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.
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.
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 engine is burning oil. Losing oil quickly and no leak.
Timing chain actuators diagnosed problem by dealer . Car hesitating, stalling out while driving.
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.
While driving on the interstate in below freezing weather the low oil pressure light illuminated directing me to stop the vehicle immediately. After waiting 2 hours in freezing temperatures I was able to get vehicle towed to a mechanic and the rear main oil seal had blow out due to a blocked pcv valve. This is a know issue up to 2013 gmc terrains and mine is 2014. Pictures from the special coverage bulletin 14882 looks like identical part still used in the 2014.
Tl* the contact called on behalf of his daughter who owns a 2014 gmc terrain. The contact stated that while his daughter was driving 60 MPH, without warning, the rear main seal fractured causing oil to leak from the vehicle. The vehicle was towed to the residence. The vehicle was not diagnosed nor repaired. The contact, a certified mechanic, inspected the vehicle and noticed the oil leaking from the rear main seal. Tom davis chevrolet buick (2831 n 16th st, parsons, ks 67357, (620) 860-0751) was contacted and informed of the failure. The contact was informed that the VIN was not under recall. The manufacturer was notified of the failure however, no further assistance was provided. The failure mileage was approximately 106,000.
While driving on highway at approximately 70 MPH, on low temperature day (~10*f), smoke began emitting from bottom of vehicle with pungent smell. The vehicle was immediately pulled over and shut off. There was oil covering the entire undercarriage. The oil was present substantially on the exhaust system, allowing for potential of fire if vehicle continued driving. The rear main seal was leaking and required to be towed home then to dealer at later date for repair. The repair and associated remedies followed tsb 19-na-021 but were not warrantied as the vehicle's VIN did not fall under the associated bulletin's guidelines. All repairs and remedies were identical to previous reported failures of above listed bulletin.
Left my house on a very cold morning (below 10 degrees) and while I was driving and my engine started making a very loud clattering noise. Low power message displayed on the dash and several lights displayed. Nothing prior to the noise. Immediately pulled in and parked my vehicle. I had the codes ran, checked the oil and it had none! The vehicle was checked out and the pcv valve failed/froze causing combustion in the engine and blew out the rear main seal. According to service bulletin 14882 this was an issue on the 2010-2013 gmc terrains and 2010-2014 chevrolet equinox (which is basically the same thing) a recall was issued. My vehicle is a 2014 (who's to say when the engine was not built in 2013?) and it doesn't appear the issue was fixed on the 2014s which is going to cost me approximately $3000 to fix. When the rear main seal blew (or started leaking) it coated the whole underside of my vehicle which could have cause me to wreck or catch fire. I had to have my vehicle towed since I was several miles from home.
Car is experiencing oil consumption at a high rate. I looked into his and I guess is very common. And I guess gm won't do anything about it. What do I do now? Do I junk it and take a loss as the motor is now making noise . There has got to be something to do.
During cold temperatures (14 degrees) my pcv valve failed to work while sitting at a read light while I was driving home from work on a city street resulting in my rear main seal blowing. This was an issue on the 2010-2013 gmc terrains and other gm vehicles as noted in the service bulletin 14882. My car is a 2014 and clearly the issue has not been resolved which has cost me nearly $3000 in repairs. Luckily I was close to home but this issue could've left me stranded in below freezing temperatures. This issue also caused oil to leak everywhere and could've resulted in a fire. My car was smoking and smelled as though something was burning.
