I have a GMC 2012 slt 1 with 2.4 cylinder car that I bought in 2011. It has 75K miles now. Recently got to know from my dealer that there is a issue with the engine oil consumption and piston needs to be replaced and was referred to a special coverage information for 2011 vehicle with similar issue but not for a 2012 vehicle - GM.oemdtc.com/3953/15285-excessive-engine-oil-consumption-2011-Chevrolet-equinox-GMC-Terrain if my 2012 car bought in 2011 is also giving the same problem as confirmed by certified GMC service dealer, then why is it not covered under GM's special coverage.

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.

I have had this car for less than a year, bought from a dealer, and I have checked the background to which there have not been any type of accident or damage from what was provided to me. It randomly started shaking uncontrollably and shutting off while I was driving. Now mind you, as a pregnant woman driving on the highway, this is not safe. My engine light turned on. Though I could have gotten in an accident, by the grace of god people moved out the way and allowed me to get off and to the side.

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.

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. I have looked online and seen that many others have had this issue of oil consumption with 2010-2013 Terrains and that there is a bulletin on it (below): GM.oemdtc.com/1893/excessive-oil-consumption-2010-2013-Buick-Chevrolet-GMC#comment-1224 I call the dealership and the GMC customer service line, check my VIN and they say there are no recalls on my car. What am I to do? this is an ongoing issue that many others have complained about in bulletins and on the website above. I feel that this issue has done its damage on the engine and is going to cost me thousands to repair.

On the 2.4L ecotec engine, the PCV orifice in the intake manifold becomes clogged which causes oil to be pulled into the engine combustion chamber and burned. This causes an excess build up of carbon inside the engine and on the spark plugs which in turn causes the vehicle to idle roughly and stall out while sitting idle, such as at a stop light. GM has issued a special coverage service bulletin (#: 14882) but only for specific VIN's. it has become known that there are many other vehicles that fall under the year groups stated by GM in their service bulletin, even if it's a VIN that they deem is safe from the problem, but they refuse to recall the vehicles even if they are affected by the known problem. This is a safety issue that causes the vehicle to die while trying to leave from a stationary position once the engine has warmed up, for example passing through an intersection after a red light.

- Virginia Beach, VA, USA

The contact owns a 2012 GMC Terrain. While driving approximately 35 mph, there was an abnormal noise coming from the engine and the vehicle started to decelerate. The contact coasted into a parking lot and noticed an oil odor around the vehicle. The contact noticed that the vehicle was leaking oil all over the parking lot. The vehicle was towed to an independent mechanic where it was diagnosed that the PCV valve was frozen and was not circulating caused by excessive pressure leaking out oil. The intake manifold and cam cover needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 11,000. The consumer requested an update of the investigation concerning the vehicle's PCV valve.

At low idle or when backing up and accelerating vehicle the engine stalls. This typically occurs after driving car for 10-15 minutes. Engine light appears. It will continue to stall unless holding down brake & accelerator at same time. Stops stalling when speed increases, but stalls on low speeds & backing up continually. Code indicates camshaft adjuster sensor. First sensor replaced. Problem occurred again immediately after leaving garage. Second sensor replaced. Problem occurred once again! mechanic thinks it could be ground wiring issue is burning up the camshaft sensors. The car is not safe to drive.

I was traveling on the toll way and went to pass a vehicle going below the speed limit. Upon acceleration (approx 53 mph), I heard a muffled pop in the engine compartment and white smoke trailed the vehicle. No warning lights went off prior and I do not recall seeing any after the "pop". I stopped the vehicle and turned off the engine, opened the hood to find flames under the engine in vicinity of the oil pan. I was unable to put out the flames and the fire consumed the vehicle. I vehicle was well maintained and have no idea what the origin of the fire was.

I have had issues with this vehicle ever since its purchase 01/2015. I took the vehicle in for service and was told the service contract would not cover my issue and that the issue was caused by lack of maintenance, which is not the case as I maintain the oil in this vehicle and even had to purchase a new battery for the vehicle recently.this car's engine repeatedly stops, especially when approaching a red light or stop sign or at the moment of acceleration. I have had to avoid many accidents due to people driving up on me because I should have been accelerating at the time but my car turned off. The battery would die on this car on a weekly basis which caused me to purchase a battery and there is still no progress in the vehicle. The motor knocks badly upon startup, especially in the mornings. The engine is very weak after an independent diagnostic check. And just last week, as I was driving on the highway at normal speeds, the muffler shield broke, fell, and began scraping against the highway. There are electrical issues as well as the lighting in the car gets dim when we are in the dark but bright when the sun is out. Also, the seatbelt for the passenger's side constantly rings sending a notification that the seatbelt needs to be latched, even when no one else or nothing else is in that seat. I fear that one day I may need that air bag and it might not work because the seatbelt appears to be faulty. Also, another issue, which is not necessarily a safety issue, but an extreme nuisance and also maybe an electrical issue is the car radio and volume will freeze at any given moment and the car has to be stopped and idle for a period of time before the radio is active and able to turn channels again. The safety issues for this car are real and I am in fear that I will get hit from behind due to the faulty engine.

- Dallas, TX, USA

Excessive oil burn with no warning of low oil until about one quart left in engine. Only check engine light came on. Yes the manual says check oil at every fill up but after owning many cars over 38 years without this problem it would seem the manual was written to protect GM. I would not have purchased the vehicle if I knew I had to put in a quart of oil every 1500 miles. Google this. Im not the only one.

Within two days' time, my 2012 GMC Terrain stalled four different times, all at low speeds. The first time was backing out of the driveway; the other three happened the following day starting up from city street intersections. My concern is being rear-ended in those situations, or beginning to make a left hand turn in front of oncoming traffic thinking you have enough time and then having the car stall. Another concern is having the stalling issue occur at higher speeds, although that never happened to me. I took the car into the dealership on that second day, and they replaced the intake camshaft position actuator solenoid valve. The problem has not repeated itself since. Thank you.

I purchased my 2012 GMC Terrain from clay cooley in irving, tx on 01/05/2015 with an extended service contract. I have had issues with this vehicle ever since. I took the vehicle in for service and was told the service contract would not cover my issue and that the issue was caused by lack of maintenance, which is not the case as I maintain the oil in this vehicle and even had to purchase a new battery for the vehicle recently. I am attaching a picture of the condition of the battery shortly after the vehicle was sold to me to where I contacted my sales agent and he advised me to check my service contract.

- Muskogee, OK, USA

Car started making rattling noise on startup. Got worse. Took to a few car places and thought it was the oil. But the oil was fine. Then the engine light came on and a second later the car shut off while I was diving down the road with my two babies!! very dangerous! ran into a friend who has the same make and model car as mine and said she had the exact same problems. Has 80K miles and has already changed the timing belt five times. Car just shuts off. Extremely dangerous! I will report this to everyone I know and warn them.
