Engine Burning Oil problems of the 2012 GMC Terrain - part 1

My husband started the Terrain, backed out of garage & it died. It started again then. He was driving it 10 miles from our home & when driving on highway in the country, the car would not accelerate over 20 mph even as he pressed down the accelerator. When he reached his destination. He shut off the car & tried to restart it to move it & it started. Couple days later, it started to move in garage however when wanting to remove it from garage, the car would not start. Hasn't since. I was ckg oil periodically & when needed so there was still oil in it. Towed it to dealer & told us the timing chain was bad. Same as what GMC & chevy 2011 & 2012 cars are dealing with. Bad oil consumption. GMC nor our dealership who sold us this car 2 years ago will back their product. They shouldn't have sold is this car in the first place since there was already a law suit against Chevrolet & GMC for this problem. I still owe money on this car & no one will help with this dilemma.

While backing out of driveway, the engine stopped without warning and vehicle would not restart. After being towed for service, we learned there was almost no oil left, causing the timing chains to fail and the engine was damaged beyond repair. We had driven the vehicle less than 12 hours prior and there were no warning lights such as low oil, check engine, etc. The vehicle has just under 78,000 miles on it and should have been 1,200 miles and 2 months from needing an oil change. This model year vehicle is known to be equipped with faulty piston ring assemblies which lead to excessive oil consumption. Additionally, there is no oil pressure sensor to alert the driver to the low oil; consequently, this misleads the owner into operating the vehicle with inadequate oil levels and causing engine damage. Complete engine failure can occur suddenly, creating an enormous safety hazard; we are lucky we were not driving at highway speeds or in heavy traffic at the time it occurred. Gm issued a special coverage adjustment, but it was not nearly adequate to cover the extent of damage that can and does occur as a result of this defect, leaving many drivers stuck with unreliable, unsafe vehicles or astronomically expensive repairs.

I just found out that this vehicle has a recall concerning oil consumption. I just found out about this issue. I want to know what could be done to have my vehicle repaired.

Car is burning excessive amount of oil. Now the engine has seized up.

Engine failure due to oil consumption no check oil light came on. Happens with no warning.

Pistons are bad and dealership at 16400 w colfax Ave,golden CO 80401 refuses to replace and oil consumption is to much. This problem has been going on for to long I was told by management after I paid for a high pressure fuel pump replacement if the problem was still there it would be fixed at no charge to me. Since then the manager quit and there is all differant staff and I have tried the corporate office still not resolved the only thing left is small claims court with a cap at $7000. I do not want to go to court if I really do not have to but if necessary I already have the paperwork to file. The dealership had my vehicle for over two weeks running diagnostics with no answer I asked them to check the pressure coming from the oil cap when you remove it. Nothing they just replaced the high pressure fuel pump and the problem is still there this vehicle is not safe to drive and can cause a wreck if not fixed. Loses power and gas pedal hits the floor I had to pay for a rental car the whole time the dealership had my vehicle because they said they would get us a loner vehicle and that never happened this will be my last attempt to resolve this matter out of court.

Me and my wife own a 2012 GMC Terrain 2. 4l engine. Oil consumption is 1 quart every 500 miles the dealership located at 16400 w colfax Ave golden CO had are vehicle for two weeks running diagnostics tests and using a on board computer hooked up to the vehicle with no answer for why the vehicle was losing power and gas pedal going to the floor with no codes pulling up as they mimicked the problem with a on board computer hooked up to the vehicle while a gm tech test drove the Terrain this is a major problem for driving on the highway its like going 45 mph on the highway and slamming on you'r brakes then the vehicle kicks back into gear. My wife is a nurse and needs her vehicle to get to and from work especially with covid-19 if she cant make it to work people could die covid is nothing to play around with and nurses are not allowed to call in while covid is going on this problem with this Terrain needs to be investigated if a gm certified tech does not know what is going on with this vehicle who would.

I received an oil change at the dealership, within less than a thousand miles I checked my oil and it was completly dry,no oil on the dipstick at all. I added 2 quarts of oil during that weekend and then went to dealership the next day. When I went to dealership they told me my oil was about . 5 quart overfilled after having an oil change 1000 miles prior, adding 2 quarts of oil additionally and only returning to have them check it a day later. So leaving the dealership I was told to drive 1000 miles then return to have them check it. After 1000 miles unreturned again and they told me my oil was too low. They then told me to drive another 1000 miles and return once again for another check at which time they again filled my oil to the recommended amount. I'm only st about 500 miles into the 2nd check after driving 1000 miles and I checked my oil at home this weekend and it's already low. Very frustrated because if I wasnt checking it, and I was doing what inwas supposed to by getting oil changes then it seems like in less than 500 I'd be low and likely blow my engine if I continue driving not worrying about checking cause I should have plenty of oil given I had recently had an oil change and was well within the limits before needing to return for my next service. During the first waiting period to drive 1000 miles my car started knocking in the engine, was just dieing when I would take my foot off break to accelerate and overall was running very rough. Recently was told some of the codes that were coming up when I had it hooked up for the check engine light being on, that the codes could be related to the oil consumption and problems it was causing for rest of car.

At 77,894 miles, & about 3,000 miles into previous oil change, the car shut off while my wife was driving with our children in the car and stopped in the middle of the road. Several attempts to re-start the engine were unsuccessful. Prior to this there was no warning signs of issues such as check engine light, odd noise, etc. The car did not allow time for the vehicle to drift off the main road and created a risk of potential collision with other vehicles. Luckily this occurred in a residential area and not on the highway a few minutes earlier. We had the vehicle towed to my certified mechanic and upon inspection identified there was no oil in the car. There is no sign of oil leakage, and the oil had been changed and topped off less than 3000 miles prior to this. Approx. 2 years prior, we receiving the bulletin & took the vehicle to the GMC dealer, coral springs auto mall to conduct a oil consumption test. The service advisor checked the dipstick upon my return as instructed 2000 miles later & advised it "appeared" that my car did not have the issue. Remembering this instance, 2 years later, while still within the special coverage warranty parameters, I had the car towed back to coral springs auto mall GMC for the repair. I am now being told by both the service manager and GMC customer care agent that since I did not bring the vehicle in sooner, they will not honor the coverage, however they do have record of the inspection on 06/06/17 but the advisor did not update the ticket with results. I am also told that based on loyalty with the dealer, they could honor the coverage, however since I do not service my car there, I have no loyalty in order for them to honor the claim and repair the vehicle. They quoted $5,800 to replace an engine they know to be faulty. Due to "lack of lubrication" caused by excessive oil consumption the engine has significant internal damage.

The contact owns a 2012 GMC Terrain. The contact stated that the check engine warning indicator was flashing and remained illuminated. The vehicle was taken to a certified independent mechanic where it was diagnosed that the sensors needed to be checked due to excessive oil burning. The contact requested the diagnosis in writing. The dealer was not contacted. The manufacturer was notified of the failure. The failure mileage was not available.

Oil consumption is out of control! when I bought the SUV used at 63k I could hear within 65k I need oil just from the sound of the engine. I bought a 5 qt at wal-mart because there was less than a quart on the stick. I got and oil change prior on 8-13-19 mechanic showed I was low already at 66k and wasn't due for another till 72,780 I'm at 72k and engine needs oil! hope the class action lawsuit abides to my complaint.

The vehicle has excessive oil consumption. I have to keep adding motor oil a couple weeks after doing oil change.

The truck burns oil incredibly fast. Due to this ongoing issue, it caused the timing chain to break and we had to spend nearly $800 for engine repairs. Even after having it in the shop numerous times for the same issue, the truck still eats through oil incredibly fast and it seems to only be getting worse. I received a letter in the mail saying that there was a recall regarding this but that they would send me info through the mail on how to go about fixing this issue, but I never received anything else about the recall.

Massive oil consumption!! ever si fr the purchase of the vehicle there has been massive oil consumption leak. Taken back to the dealer for service to take care of the problem, they claim they don’t see a problem! this car has been oil leaking and also draining oil somewhere to the engine causing also power rain engine issues and also contact oil light on. Reported to GMC as well and corporate, no response! this vehicle has cut off and lost power because of oil consumption on highway with my children in the car! I have been emailing with no avail! this matter needs to be rectified immediately! it is a death trap!.

High oil consumption. No leaks under car. I've to add 3 quarter of oil every week.

Vehicle was obviously burning excessive oil. Took it to a gm dealership and was told it was a non issue. Now the vehicle is past the gm max mileage for their recall (they won't take responsibility)!and has developed a white white frothy residue on oil cap, dip stick. (piston rings and/or gasket failure). Will never buy a gm product again!.

This engine burns through oil at an accelerated rate. My car has 48,000 miles on it and the engine is almost dead. The car stalls or shuts off when stopped at a red light, stop sign etc.

Tl the contact owns a 2012 GMC Terrain. The contact purchased the vehicle used. Both the dealer and the manufacturer did not inform the contact that there was a special recall on the vehicle regarding excessive oil consumption caused by an oil ring malfunction. The malfunction caused the engine to seize. The vehicle was taken to carbone Buick GMC of utica (5700 hoatio st, utica, NY 13502, (888) 471-8416) who stated that the vehicle had 2,000 miles over the 100,000 mile limit to be covered under the special recall. The dealer, after checking with the manufacturer, offered to pay for one third of the cost to replace the engine. The repair would cost $4,000. The vehicle remained at the dealer and had not been repaired. The contact was referred by his state's attorney general's office to NHTSA. The failure mileage was 122,000.

My car consumes oil in between oil changes, catalytic converter has gone bad which should not be happening in a 2012, and rear passenger door electrical failure. They have been recalled in other areas for the oil consumption and catalytic converter but not for my specific VIN number. GMC needs to recall the Terrains to fix the oil consumption, catalytic converter issue, and the rear passenger doors. The oil consumption and catalytic converter are two major issues that should be fixed immediately by GMC since they know it is an issue with that year.

Have a serious oil consumption problem have to have oil changed every 500 miles, it starts to shake when start up it turns off keep getting camshaft codes also got misfire code.

The camshaft position actuator solenoid on my vehicle failed as I was crossing an intersection, almost causing an accident. From my research, this is a very, very common occurence in these engines that gm has known about since 2010. It is the result of a defective part and oil consumption issues. Gm issued a voluntary recall for the same exact part in the 2011 Terrain models, yet did not issue any recalls for the 2012 models, even though it is the exact same part and the exact same motor. This is a serious safety issue that causes the engine to lose power at a critical time - when the driver attempts to accelerate. I have no doubt that this issue has caused accidents based on my experience when the failure occured.

2. 4 ecotec engines excessive oil consumption affects thousands of GMC/chevy consumers vehicles 2011-2013. Although in final stages of class action, GMC continues to deny the serious nature of the problem. Oil indicator does not illuminate, engines blown, failed catalytic converters, rear main seals, timing chains and more. Not only a huge financial impact for owners but also a serious safety issue. GMC suggests a piston ring failure but only offers resolution to very few owners. Please consider a recall on these vehicles. You will find more information here: https://topclassactions. .

I have owned my 2012 GMC Terrain for almost two years. In that time have had to have several repairs done. My check engine light comes on and every time it does the dealership finds a new issue. I was advised by the dealership that there was a recall for my engine. However, will not take care of the issue with out an oil consumption test and charging me each time they put in oil. The vehicle runs hard and makes a lot of noise. I have already put in several thousands in repairs since I purchased the vehicle and would just like the vehicle to run correctly.

Excessive oil consumption at less than 65,000 miles, warning lights do not activate to indicate a problem. Next the timing chain broke and was repaired, now the catalytic converter needs replacement. All result of oil consumption and is a widely known issue affecting thousands of 2010-2013 GMC Terrains in the us but GMC will not help or take recall action. A class action lawsuit is underway, but it won't be approved until oct 2019 (state of FL), two others on a stay (IL and CA) until FL is finalized. I purchased my vehicle used with a salvage title. The oil problem is in no way connected with the salvage title (rear end damage, and certified by state as safe). GMC mailed me a special coverage letter dated may 2017 but they won't honor it because I did not purchase from a GMC dealer or have my routine maintenance at GMC service. In fact when I received the letter I followed the instructions and contacted a local GMC service but they called me back telling me they are cancelling the appointment because when they looked up my VIN and saw it is a salvage title. I told them I have the letter from gm dated may 2017 but they told me I should not have received the letter, that I don't qualify. The letter reads in part: "GMC is providing owners with additional protection for the condition, if this condition occurs within 7 years and 6 months or 120000 miles the condition will be repaired at no charge. .

Gm used faulty piston rings resulting in excessive oil consumption. This resulted in blown engines. This vehicle also does not have a oil gauge or low oil light to warn the consumer of the know oil consumption issue. I was driving home and the engine started to ping as I got to the driveway. I turned off the engine, and it would not start again. I took it to gm and they said the engine was blown. See #16118-special coverage-excessive engine oil consumption- (Jan 28,2020) gm was sued, but are denying most claims. See Terrain-equinox oil consumption recall group on facebook. The engine blew due to the oil leaking out of the pistons.

Excessive oil consumption, ecotec 2. 4 engine.

After owning this car for over 4 years we are just now finding out that general motors has issued what they call special bulletins on the excessive oil consumption problem we have been having. We first started noticing the problem in February of 2018 when the car started vibrating, shaking, and stalling while driving. I took the car to firestone to have the oil checked and the car was shaking so bad that they refused to even look at it for fear of being held liable for damages. Come to find out that my car only had about 1. 5 quarts of oil in it and after the oil was changed it began riding smooth again. However we noticed after about 6 weeks it was low on oil again. Basically we ended up having to get a oil change every 6-7 weeks or at least add a quart of oil to the car ever 3 weeks. Now we've come to find out that special bulletins(bulletin #16118 or 14882) have been issued on this problem with my Terrain. My problem is no letter or contact was ever sent to notify me of this issue. My car has been to the local GMC dealer on multiple occasions and I would like to know why I was never notified about this problem or these bulletins. The problem I have now is after reading the bulletin we've come to find out that my car may be out of the warranty phase. I currently have 132,000 miles on it and the tsp says 7 1/2 years or 120,000 miles. If we had been made aware of the tsp we would have surely taken it to the dealership to have it check. Better yet, when my car was at the dealership for a fuel line problem or repair of the moon roof we would have expected to be notified of any tsp's then. I strongly feel that this excessive oil consumption issue with my car should be fixed, as it had less than 120,000 miles on it when the problem first started occurring over a year and 1/2 ago and we were never notified in a timely fashion.

Vehicle check engine light came on at 50,000 miles, would not pass inspection. Computer did not show what problem was. Car would cut off in drive in idle. Car would shake. Mechanics put in new parts and battery for more than $1200. Still was not fixed. Mechanic went to a dealership to inquire if they had seen this problem. At the dealership it was discovered that many of the parts that would cause the problem were on recall. Gm had not posted these recalls or notified me, the owner. After inspecting the car they said there was too much wrong to repair and the entire engine would need to be replaced. They said I would need to drive 2000 miles to check oil consumption. They never made us aware there may be problem with the oil consumption. I am 68 yrs old and walk with a walker. I am in the hospital often. The mechanics said they would drive the car as much as they thought necessary to determine oil consumption. While driving the vehicle in charlotte nc the car started smoking and caught fire. The driver forced his way out but had that been me, I probably would have died due to my handicap. I have now been without a vehicle for over a month. I have contacted gm but they are slow for any resolution. I asked for a loaner vehicle but was told they couldn't do that now.

Purchased 2012 GMC Terrain. Started running poorly and eventually check engine light came on. Was unable to get an inspection sticker so I took it to gm dealer. I was told that I needed timing chain replaced. $1800. I then asked if it could have anything to do with the recal letter l recieived that specified excessive oil consumption. The dealer advised me it had nothing to do with timing chain. I refused to pay and took it to my own mechanic. He found lack of oil and sludge in my engine. After flushing it out and putting new oil in the check engine light went off. I then took it back to gm and requested oil consumption test. The dealer determined that my vehicle burned 1 quart of oil at 1000 miles. The vehicle failed the consumption test. They now have advised me that they are replacing pistons, rings and timing chain. Very frustrated that I was lied to about this issue and have spent alot of money out of pocket that was totally not needed to be spent.

I bought my vehicle brand new and have records of every maintenance done in a timely manner. On 03/31/2017, I drove 38 miles to a furniture store with my 11 month old baby and wife. When I returned to my car, it would not start. When I turn the car on, it clicks but no power goes to the engine. There was no engine light on and no indication that something was wrong with the vehicle. I ended up towing it to a GMC dealership. They did inspection and advised the timing chain broke and had a chain effect braking rods in the engine. They also mentioned something about the engine oil burning. I was advised by the gm dealers that the whole engine will need to be replaced and advised my warranty expired on 1/14/2017. I contacted gm customer service and have opened a case file but I am not sure if they will do anything to assist me. I did some research online and it appears multiple customers who have owned GMC Terrain have had similar issues. If the timing chain broke while I was driving, it is quite possible there might have been a fatality and I or my family might not be alive today.

The contact owns a 2012 GMC Terrain. The contact stated that the vehicle operated abnormally. The dealer diagnosed that the malfunction was due to excessive oil consumption. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 105,649.

The vehicle has excessive oil consumption. I have to add 3 qts between every oil change to bring it back to the correct level. I know when it needs this because the valve train gets very loud as it is starved for lubrication. It also will have irregular rpm levels from time to time as well as hard starts. Vehicle has 40k miles on it. I have been having to do this for the last 10-12k miles until I heard of this bulletin.

Excessive oil consumption 3k miles 2 quarters of oil consumption.

Excessive engine oil consumption 2 quarters per every 3000 miles. Vehicle is now 71k miles I changed the oil 3 weeks ago and it was missing 2. 5 quarters of oil I have driven the car around 800 miles after the oil change and is half way on the deep stick am afraid if I keep driving it for 3 to 4k miles it will be very low on oil again and I purchased this car 7 months ago fro the dealership and it had 55k miles at the time I always noticed to be low of motor oil and I thought it was normal but it's getting worse by the time going by. I think is too soon to be burning motor oil at those low miles.

Oil consumption issue: I realized about 3 months ago that my car engine would shake a bit on start up and during idle. I took it into the dealership for a diagnostic test and was told that there was very little oil in the car and that it was burnt. I was very surprised because I have never had an issue like this before. So we got an oil change and that was that. Engine still shook on idle and during startup. 5000 miles later I realize that it is time for an oil change and check the dip stick and find that nothing appears on it, indicating that it is short at least 1. 25 quarts. I fill it up with 0. 5 quarts and still nothing on the dip stick. . Read more...
