general problems of the 2011 GMC Terrain

SUV gets a slow down warning and it stops shuts off , it’s happened several times now I’m scared!!you wait few minutes it turns back on , mechanic said this a complain about this vehicle all the time , it has not been repaired I’m disabled with no money , I was on the highway and thank god I was on the slow lane if not I would have been killed by an eighteen wheeler. GMC is waiting for someone to die and probably address this issue.

My car wouldn’t start, later found out it was due to timing chain issue which ended up blowing up my engine. I live 40 minutes from work and am consistently driving on the interstate for at least an hour a day. Gm said there’s nothing they can do even though there’s been class action lawsuits for the engine. My car has also had oil consumption problems. I bought my car in March of 2022. The engine blew up by November 2022. I barely got my car back in September 2023. After the engine replacement, still wouldn’t turn on, over heated immediately when I did get it back. After paying $7440 for the engine replacement I had to fork over snother $650 to replace the fuel pump control module, and an engine control unit. My car overheated again just 2 weeks ago!!!!.

Was driving home from work had a half tank of gas no lights or anything came on, car just shut off was not able to start it from that point. I spoke with car lot to whom I'm making payments with and not able to get anything done with the vehicle. Now I've lost my job and I'm about to be homeless due to this mechanic problem on this vehicle.

Diagnosed with oil consumption problem, p0014 code for check engine light, showing 10 degrees on scanner, recommended timing chain alignment, my car shut off while driving it, GMC has class action lawsuit, told me my VIN was eligible for it, but will not let me submit a claim, I have owned this car for a year, constant oil changes about every 2 months.

I purchased the vehicle it ran great. Within a couple of weeks, it started stalling when I go to take off in the middle of intersections or pulling out onto a road. It will run fine I stop it idles ok and when I touch the gas pedal it will start out into the road and then just die.

The vehicle going through oil like made and stalling in the middle of intersections or pulling onto a road. This has caused other people to almost hit me or go off the road to avoid an accident. I will start out into an intersection get in the middle and it dies. Turning onto a different road this happens also in motion going at normal speeds for the road.

When inserting the gasoline pump's nozzle to refuel the vehicle, the nozzle does not lock into place during the pumping of gasoline. Vehicle owner has to manually hold the fuel dispenser's handle to refuel their vehicle during the entire 16 gallon operation. There appears to be a part missing that would control the safe automatic refueling of this vehicle, but that part is not on my vehicle.

I purchased the vehicle in March 2018. From the date of purchase, the service engine and/or change oil lights would turn on. Every time I took the vehicle to my mechanic, it needed oil. In January 2020, I got a notice from GMC about the settlement of a lawsuit regarding vehicle oil consumption. I took the vehicle to my local GMC and the manager read the "notice of approval of class action settlement and claim form" that was sent to me. The lawsuit requires GMC to pay for repairs or reimburse customers for the repairs. My vehicle had not had the necessary repairs done to it, so the manager instructed me to approve the necessary repairs and pay for them out of pocket because GMC would reimburse me. The repairs were completed on February 7, 2020. I followed all the guidelines provided to me by GMC in order to get the reimbursement. I mailed documents to them a week after the repairs were completed, months before the deadline of may 16, 2020. After waiting over a month and not getting reimbursed, I called GMC customer services (1-866-790-5600) on April 11, 2020. I was informed by GMC customer service to expect a reimbursement check for repairs and rental car fees within two weeks. After not receiving the reimbursement, I called again in June and July 2020 and given the same information-wait. This continued throughout the summer. The delay was blamed on covid-19. I called again in late September 2020, and they instructed me to email all the documents and that the check would arrive in two weeks. On September 30, 2020, I emailed all the documents to GMC. After waiting another two weeks, I called them and they again said it would come in two weeks. On November 10, 2020, I sent another email asking for the reimbursement check. A week later, I got a letter stating I did not qualify for reimbursement because the time had passed/expired.

Significant exhaust fumes accumulating inside passenger cabin during idle/stop. Volume of gases smell less while in motion but still evident. Significant reduction in engine power noticable; as well as erratic noise from the engine and extemely hesitant acceleration response.

My car shut off once while I was in idle at a red light and second time when I was backing up into a parking spot some one who was driving opposite me could have hit me when the car abruptly stopped. Luckily they were going very slow and stopped when my car stopped. The engine shuts off as well as the lights on the dash but when you put it in park and start it up again the engine starts back up and no check engine lights appear. Can you please look into this?.

Engine failure: timing chain had excessive slack causing guide to be sheared off. Timing chain guide bolt was completely stripped requiring both the timing chain and cylinder head to be replaced. Safety: the vehicle stalled while driving problem: problem was confirmed by a dealer warnings: the check engine light came on as the vehicle stalled.

The car was taken into steven lust automotive and we were told that a transfer seal needed to be replaced and that GMC was aware of the issue but would only warranty the issue if the car was produced in a certain factory. Same year same model all having same issue but produced in a different plant. Now the stabililtrac warning comes on and from research on the web this is a common issue that they are aware of also but refuse to fix. This car only has 66000 miles on it. We also contacted GMC and they told us that they are aware of the problem but will not warranty it unless is was produced at a certain factory. When the stabilitrac warning was noted I was driving down the highway and the engine just shut down. I do believe this issue is due to the excessive oil leak coming from the seal. This is the second time that I have placed this complaint. When I called to confirm that I placed the complaint no one could find it.

My car will stop while im driving and I didnt get the proper dignostics of why it was doing that, they just told me to switch my gas to premium. & then my check engine light came on . But now my engine power is in reduced and I dont unerdstand why either. I havent had this truck for a year and its been giving me problems since I got it.

Gas station pump will not stay on when refueling.

Exhaust fumes are entering the vehicle through the air vents, gets worse when idling. Seatbelt does not buckle.

I bought a used 2011 GMC Terrain with a clean carfax and 35000 miles on it. I have had nothing but problems. The car burn at least a quart of oil every 2 weeks. The constantly just cuts off when driving. GMC needs to do sometime about this before peolpe are killed.

The engine will randomly stall and shut off. There are several complaints of you google the problem. This is a serious safety hazard.

The vehicle is consuming up to 2 qts of oil every 1000 miles. The low oil level light does not illuminate, even when the oil level falls below 2 qts low.

Was sold a vehicle with multiple mechanical problems with it within the first week of purchase as well as an open recall on this vehicle.

Going to visit son, daughter in law and grandaughter in virginia from michigan. Got reduced power message with stability control light. First time was without warning on the curvy hilly pennsylvania turnpike in traffic at appx 70 mph. . Lost power on hill had no acceleration, vehicle decelerated in front of traffic. Put on hazards and worked our way over to shoulder across 2 lanes of traffic. Thank god this didn't cause a pileup of holiday travelers. Stopped vehicle, engine was misfiring, there was no throttle response. Shut off engine and restarted, power was back but check engine light is on. Continued trip, 2nd incident was about 1 hour later also without warning. Had about 5 incidents this trip.

While driving down a busy two lane road I pulled out into an intersection in an attempt to make a left hand turn when the car stalled in the middle of traffic. I turned the car off and turned it back on again and it worked. However, later that day it stalled again while it was sitting at an intersection. I brought it to the dealership for repair and they said it was not covered under warranty even though I still had one. They said there was a fuel leak at the fuel composition sensor. They replaced the sensor. Gm extended special coverage # 17097 in may 1, 2017 for 2011-2013 chevy equinox and GMC Terrains that are equipped with flex fuel due to a fuel leak at the fuel composition sensor but they did not include my 2011 model Terrain that is not equipped with flex fuel but it should have been. This issue was out of my control as it was a manufacturing defect in the fact that they placed the composition sensor below the frame exposing it to damage from road debris.

Upon entering garage,smelled odor of gas by car. . . Looked underneath,,small puddle of fuel,,closer examination found pinhole in rust patch on fuel line. . Other rust areas noticed,but this was only leak. Corrosion is to be expected. But not to the point of failure after only 4 and one half years. . Car was bought new and well maintained ,also always garage kept. Being out of warranty (of course!), I had to negoitiate with the dealer for a decent cost of the repair. . I believe inferior quality is to blame and believe this can and will happen to others,hopefully without serious consequences. . .

While driving the vehicle stalled from 35-40 mph to 5 mph. A message came on the screen " engine power reduced". Had I been on highway that would be ended in accident. Contacted gm and everyone I have been talking to them seems to be reading a script to me.

While traveling on interstate 376 west out of down town pittsburgh, PA during rush hour the service stabilitrack warning message appeared and then the reduced engine power warning came on. At the time we were traveling about 45 mph and the engine would not go any faster than 20 mph when we got the messages, we had to try to get over to the side of the road. . . . We turned off the vehicle and waited 10 minutes and it reset itself. . . It happened 3 more times on Monday 12/22 and the last time I could barely turn the steering wheel. . It turned out to be the throttle body needing replaced.

Well it appears that there are several complaints on here about the 2011 Terrain stalling. It's been happening to me off and on the past several months. I would be in traffic and it would stall, I would be at a stop light and it would stall, I would go to back out of my driveway and it would stall. I took it in and they can't find anything wrong. Well last night it finally died. Great!! I heard noise when I started the vehicle that sounded like plastic water bottles rubbing together. I had a bag in my front seat so assumed it was nothing. It bucked forward as I put it into drive and stalled. Well. . . The stalling I'd become accustomed to so I re-started. It seemed fine until I went to accelerate onto the main road. . . It bucked, started shuttering, and wouldn't go above 5 mph. I barely got it into a parking lot before it died. I counted no less than 5 similar reports on here. I live in the metro detroit area. . . Had this happened on a highway or during rush hour, I could've been killed. Someone needs to do something before GMC has yet another scandal on their hands or how many people have to be hurt, maimed, or killed before NHTSA gets involved??.

I purchased this Terrain as the 99 GMC pickup that I purchased from sheehan had 3 total brake failures and a power steering cooler fail all due to corrosion. I was afraid to drive the 99 after the 3rd total brake failure. This is when I purchased this vehicle in November 2011. Since then due to corrosion they replaced all the wheels on the vehicle and the other day I started smelling gasoline. I took the vehicle to sheehan. They found a fuel line under the vehicle leaking as it had rusted through. I asked the service person what they did to correct this problem. I was told they replace the fuel line with the same type that had just rusted through. I asked them why they did not use stainless steel. I was told they do not do that. I now do not feel comfortable of driving this vehicle. The vehicle has not even been paid off yet and only has approximately 7000 miles on it. I have begun shopping for a non-general motors vehicle as I do not feel save driving this one.

We bought it used in 2013 and shortly after it started have serious issues . It started with the traction control light coming on and it power down. Then it would stay running spitting and sputtering after we turned the key off . So then we received a letter stating there is a recall and take it to the dealership to have it fixed . So they fixed it or at least they said it was , so we continued to drive it and the engine light came on and stayed on so I took it back and they said it was the throttle body and catalytic convert . Then we changed those parts and it still has the engine light on and spitting and sputtering after we turn the key off.
