As I was driving down the road at 55 mph hour my SUV began to shake extremely and was throttling at very high RPM's and the SUV thrash to sudden halt and continued to shake and idle very high and loud. I tried to hit the gas to get myself off the road as I was on a 2 lane highway with my 4 year old son in the car, and the engine revved and the RPM's spiked but I went not more than 15 mph, at the same time the following errors appeared on my screen: 1) service stabaili trak 2) engine power is reduced slowly I was able to safely get the car up to 35 mph and get us home safe. I did some research and seems that this is a very well known issue with GMC so I contacted GMC and was basically given the runaround. I took the car to a GMC dear today and was told it was the fuel pump that needed replaced.....

The check engine lights continually comes one and off. At first, when my husband turned on the truck and saw the check engine light we took it in and the error was for 1 coil pack. It was fine for a month, then after starting the truck again the check engine light came on, and we replaced all of the coil packs. Now when we start the truck, the check engine light may be on or off. At least once a week, when we start the truck the check engine light will be on. This issue has been reoccurring and has been going on for close to a year. The last 5 or 6 times we had it put on the machine there have been no errors found and our mechanic's baffled. Especially since the truck may stutter or become sluggish or shut off like before whenever the check engine light comes back on. If something is wrong with our vehicle but no errors are found we have no clue if there is truly something occurring and if it's causing serious damage and harm to our family. Our vehicle was manufactured in Canada and we aren't sure if there could be issues being reported in Canada that we don't know about. In addition, there are recalls that we weren't notified of but nothing pertaining to this issue.

As I was driving home from work on 2/1/18 on I94 at 72 mph, my car starting sputtering and smoking. It then started making a very loud noise and my warning light came on saying to shut off my engine. The engine shut off and I had to coast to the shoulder of the interstate. I called roadside assistance who sent a tow truck and towed me to my mechanic's garage. The mechanic looked at it the next morning and advised there was a hole in the engine block and all the oil leaked out of the hole, leaving oil all over the undercarriage of my vehicle. I filed an insurance claim, the insurance adjustor looked at it Monday and deemed it to be mechanical failure. I have 110,000 miles on the vehicle.

How do you have a recall for the same year make model but not all are included but all having the same issue? this is a serious issue and the vehicle needs to be recalled before someone get seriously hurt, especially when the vehicle is just cutting off in traffic

I have had nothing but problems with my oil consumption on my vehicle, when I first got the vehicle, it started making some noises and I didn't know what it was, until I took it in to have it looked at, it was low on oil, so I had to pay for the oil change and the fee to have it looked at, for oil consumption test, I have only had the vehicle for 1 1/2 years and the oil consumption is astronomical, seems like I have to have an oil change every 2 months and I have to add oil seems live every 1000 miles, this is a major problem, with the 2011 GMC Terrain and I think they need to recall these vehicles or fix the problem, I just go an oil change 11/2017 and was low on oil 12/2017, so I had to add oil again, until it is time to have my oil change. Now my car is leaking oil and so I have to take it in again, I have had to have my camshafts fixed 2 times, this is a problem. I am not rich, but I have to incur the charge. I still have 5 years left to pay this car off. I just wanted to voice my concern with this vehicle.

On Jan 1st it was 3F out my wife wormed up her Terrain we drove it approximately 12 miles when we started to smell something burning. Next came the engine knocking really bad. We stopped the Terrain and had it towed to the dealership found out the rear main seal blew with such force that the oil covered the muffler. This happened from the PCV being plugged and/or frozen from the cold weather. I recently found a service bulletin for that year make and model that indicates that will happen and there is a special coverage for that.(14882: Special coverage adjustment) I also received a letter from GMC about high oil consumption warranty. The Terrain may exhibit engine oil consumption. That is also a part of that 14882:adjustment now to the point I was told that this issue my wife's Terrain would be covered under the 100K/5year power train warranty our Terrain only has 71K miles on it. But the 5year are up. So GM is not taking responsibility for this issue according to both special coverage the 14882: They adjusted to 10 years or 120K miles but they are claiming even though its for that year make and model and engine and that everything that's listed is what happened to our GMC its not for our Terrain. I told them I also had a letter that they sent to us stating the oil consumption that has a adjustment of 7years 6months/120K warranty witch was part of that 14882: Special coverage they still will not take responsibility for fixing. I believe we are getting taken advantage of in this situation. They are making us pay for all repairs it may need a new engine in result of the rear seal blowing because it lost all the oil. But we would not know till the repairs start or after all repairs are made and the engine seizes. I also was told from the dealer that if we fix it and drive it down the road there is no guaranty that it will not happen again.

I received a recall letter from GMC about a knocking in the engine which just started happening in my vehicle. The recall does not show up when the dealer checked the VIN number in the computer. But before I could take my car in to be checked my engine died when I arrive at work which is 25 miles from my home. I had it towed to a GMC dearlership and was informed that my timing chain jumped and threw valve timing off causing internal engine failure.. I then had to replace the engine in a 5 year old vehicle, my warranty expired 3/2017 so this was not covered. When I called GMC I was told they may be able to cover some of the cost but since I did not replace the engine with another GMC engine which would have cost more I had to pay out of my pockets for this.

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.

"fuel sensor" issue. I took my car to GMC dealership to get the battery replaced after only 4 years and while they had it the fuel sensor went out and I could not tell how much gas I had in the car. They would not repair it because they claimed it went out on its on.

Takata recall, I thought that I had excessive oil leakage because there was no oil, when I just had a oil change the day before, but it had to be a excessive engine oil consumption, on my way from work I heard a very loud noise from my engine, and and a pop, on my dashboard was signaling oil pressure is low - stop engine, throughout the hold ordeal there was smoke coming into the car, when I was able to get to car dealer ship, I was charged $3400 to have the car fix. Then I receive a letter from GMC stating that they were doing a recall on 2012 Terrain relating to the same issue that was listed in the letter that was sent to me. They reject my reimbursement due to the fact that they saying the oil had to burning on the engine, and not excessive oil leakage, when in fact there was burning oil on my engine, which I feel cause the smoke within my vehicle, also the manager at mike anderson also said GMC rejected my claim due to the part numbers then match up to part numbers they have listed on the recall, when I view the list, it did list different number but the parts was the same, the car was in motion I was on the highway 294 going East to merrillville Indiana, which almost caused me to have a accident in which I happen to avoid.

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.
