Vehicle was jerking at a red light with foot firmly on the brake. This happened at the base of a hill on a city street. I wasn't sure if the car would lurch into oncoming traffic. As it started driving again, it began to make a rattling and knocking noise. Car then dropped a huge amount of oil on concrete. It lost power in lower speed. Luckily I was able to limp home with the car. Had to have it towed to dealership as it wasn't drivable.

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.

I also have a 2012 GMC Terrain that has an oil consumption issue that has caused complete engine failure. Approximately 2.5 weeks ago the car wouldnt start. Engine would turn over but not start. I thought that it might be the fuel pump. Had it towed to my mechanic since it has 87K miles and out of warranty. So I went to check the status of the car and the first thing I was told was there was no oil when they checked it. They added 4 quarts before trying to diagnose the problem. Mind you the oil was changed 3K miles ago and oil life monitor said it had 54% life left. They ran the car for codes and the only code that came up was for the tire pressure system, also an issue with the Terrain. No issue was found with fuel pump or sensors. Spark plugs were replaced due to them being all fouled up. That didnt fix the issue so it was determined that it must be the timing chain jumped. At that point I had it towed again to the dealership I purchase it from. I was told it would be $125 to run a diagnostic. Fine. So I get a call the next day that it was indeed the timing chain. I asked the service guy what would cause this and I was told poor lubrication or low oil pressure. Thats when I started to explain that the first shop had to put 4qts of oil in bc it was bone dry. I asked about the VIN specific letter I received last year,2017, about the oil consumption issue and isnt that why there was no oil and hence causing the timing belt to jump. He answered "no". then told that upon further inspection, the valves were bent so we were now looking at 3500 to fix or 6K to replace the engine with another problemed engine. So that is when I contacted the toll free customer service line about the situation. They told me to go back to dealership and speak to the customer experience manager.

Janurary 7th 2018 my 2012 GMC Terrain ran out of oil even though it was already fixed 6 months prior for special adjustment coverage 16118 which had pistons, piston rings, timing chain etc. Fixed to repair the oil consumption issue (see adjustments 14882 and 16118. Coverage 14882 is a result of failure to correctly fix the 16118 and is a direct result of 14882 and GMC states they will cover me if this happens. GMC customer service says my VIN # is not covered under this coverage. If its the same exact issue for (model/engine) why would VIN # matter? on top of that I took my vehicle to another dealer (dealership B) as I brought my vehicle to lets call it dealership a so many times before with the same issue. Dealership B filled it with oil and sent me on my way. I told them to make sure the issue was fixed. They said they test drove it and everything is fine and they didnt do anything but put oil in it and test. On the way home Jan. 7th the same day the car starting dying on me, stalling and making popping noises and jerking wildly which is why I brought it in the first place. Dealership B knowing dealership a "fixed" this issue 6 months before so they said they would not fix it even though they know for sure this issue was caused by coverage 14882. I told dealership a this and they said they are only going with what GMC says which is that my VIN # is not covered but they were willing to split the cost with me (roughly $850, admitting partial fault, lol) I said no and then pleaded with them that I shouldnt pay anything cause im covered. They ended the conversation with the vehicle is not covered because coverage 16882 is not related in any way to 14882 but even GMC and dealership B says they are directly related. Who is lying here" I pay $450 a month for a giant SUV that sits in my garage. GMC is knowingly breaking the law, how can they do this to so many people"

This vehicle continues to restart itself after I have exited and locked the vehicle. They keys are not in the ignition, the keys are in my hand. Please put this vehicle on the recall list and make things right. This is getting ridiculous.

- Acworth, GA, USA

I parked, turned the vehicle off and exited the vehicle. The vehicle was parked for approximately an hour and a half before I re-entered the vehicle to retrieve some items from the passenger side. As I closed the door and used the key fob to lock the vehicle, it restarted itself. This has happened multiple times and the dealership tells me that it is not their issue and that it is a manufacturing issue. Please add this particular vehicle to the recall call list for this issue prior to personal injury or damages occurring.

- Acworth, GA, USA

I turned the ignition off, exited the vehicle, walked 10-20 steps from the vehicle and the vehicle restarted itself. This is a known issue with this year, make and model. Please add this particular vehicle to the recall list.

- Acworth, GA, USA

I parked my vehicle in the driveway. Upon exiting the vehicle I used the key fob to lock the vehicle, it beeped and began to walk away. As I was about 10 steps from the vehicle, it beeped again as if I hit the fob and restarted itself. It literally restarted itself. They keys were not in the ignition, they were in my hand. I was unable to unlock the vehicle using the key fob and had to manually open the door using the actual key in the door lock. I was unable to turn the vehicle off by reinserting the key in the ignition. I wiggled the shifter and the car turned off. This is the fourth the car has been running while the keys were not in the ignition and it is the second time the vehicle restarted itself without the key being in the ignition. This is clearly a manufacturing issue. What are you waiting for to add this vehicle to the recall list? property damage and personal injury will eventually occur and then I will sue GMC for damages. I am officially putting GMC on notice. Please recall this vehicle and fix this issue.

- Acworth, GA, USA

I put the vehicle in park, turned the ignition off, removed the key from the ignition and exited the vehicle. I got some items from my trunk and went about my business. I returned to my vehicle a few minutes later only to notice the lights were on and it was running. I was unable to unlock the vehicle using the key fob and had to manually unlock the door. I put the key in the ignition to turn the vehicle off again and it would not turn off. I wiggled the gear shift and it finally turned off. This is the third time this has happened. Please add my vehicle to the recall list before someone gets injured or before there is property damage.

09/08/18 I put the vehicle in park, turned the ignition off, removed the key from the ignition and exited the vehicle. I got some items from my trunk and went about my business. About 45 minutes later, I returned to my vehicle only to notice the lights were on and it was running. I was unable to unlock the vehicle using the key fob and had to manually unlock the door. I put the key in the ignition to turn the vehicle off again and it would not turn off. I wiggled the gear shift and it finally turned off. This is the second time this has happened. Please add my vehicle to the recall list as this is the exact issue that the other GMC Terrain 2012 are having.

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.

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 engine oil consumption. Timing chain failure. Pistons, rings, exhaust manifold, muffler, door regulator, wiper motor, transmission failure. Vehicle cannot be driven

- Hanson, MA, USA

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.

My 2012 GMC Terrain 2.4L is having an issue with excessive oil consumption. I am constantly having to check my oil and it gets to 1 qt or more low between my 5K oil changes. I've seen multiple complaints with this. Because of this I have a check engine light on indicating my catalytic converter may be bad. Ive had the car for about three years. It shouldn't need the catalytic converter already. My car is due for smog next month and I've akready had to repmace the intake and exhaust sensors on the engine because of the oil issue. This happens while car is in motion being driven. It is eating up oil.

2012 gms Terrain 4 cylinder flex fuel- camshaft code, cam sensors replaced, spitting and sputtering, stalled X3 and shut off, fuel consumption noted, loss of power. GMC dealership refused to perform diagnosis on my car due to my refusal to pay for ruling out the documented fuel leak recall/special coverage. My request was only to have fuel the issue looked at and ruled out, nothing further, to ensure this was not causing my problem. I reported my problems that are consistent with the noted fuel special coverage and turned away because I did not have $120 to pay if they found it was not the problem. Upon reading my issue correlates with numerous Terrain and equinox owners. I want in this action to get something done for people like myself.
