38 Equipment problem of the 2020 GMC Terrain

Failure Date: 02/09/2024

While driving my vehicle, check engine light came on. Then, my car proceeded to flash about 4 warnings on the dash, fuel level low (had half tank of gas), engine power reduced, service esc, and service transmission. My vehicle shut itself off while driving 55 down a main highway and put itself into park. Forcing me to pull over and be stranded on the side of the road. In the way of other cars, with no way to get out of the way. I then had to shut car off, wait, and start it back it up. However, after the first time this happened, I cannot drive my vehicle more than 15 to 20 minutes without it doing this to me over and over again. To make matters worse, I am 37 weeks pregnant, and the last thing I need is to be without a car. I also had just gotten my vehicle inspected and an oil change the week before, with no issues to show. The only thing I did to my car before it did this, was remote start my vehicle, which I do every single morning and have for the little over a year I've owned this car. Also, my car has less than 60,000 miles on it!! the mechanic who is currently working on fixing this issue for me, has concluded it to be a throttle body, or the actuator of the car.

39 Equipment problem of the 2017 GMC Terrain

Failure Date: 02/01/2024

Broken rear main seal broke which causes oil leak. Almost all gm vehicles around my year have the same issue resulting in blow engine. $2000 to repair and gm told me they know of this being an issue but won’t do anything to resolve.

While turning from out of. Wheel gas station, the truck just stopped abruptly and shut off. It left me in a turning lane that curves to a stop at a stop light. I was in a dangerous spot. It was raining and dark. The burr ridge police had to come due to the position my truck was in and push me out of the lane and danger. I had it towed by aaa that night. Then had to have it towed to a mechanic. Who informed me that it was the timing chain belt.

41 Equipment problem of the 2017 GMC Terrain

Failure Date: 01/22/2024

In September of 2022 my GMC automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and pcv was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.

42 Equipment problem of the 2014 GMC Terrain

Failure Date: 01/16/2024

Vehicle started leaking oil with no indicator. Didn't realize it for at least a few days. When I smelled a burned oil smell took it to the repair shop. Was told my oil gasket blew and the engine is about shot. I also only a month earlier replaced the battery. These vehicles apparently have known battery, oil and engine issues that were known since 2010. The following class action lawsuit in missouri is pending: rachel buchholz, on behalf of herself and all others similarly situated, plaintiff, v. General motors llc, defendant. _____________________________________ our vehicle is not even at 100,000 miles! this will cost thousands of dollars to fix or we will need to purchase a new vehicle which we didn't plan on for a few years at least! this has been devastating. Please help. Lindsay popovich.

43 Equipment problem of the 2017 GMC Terrain

Failure Date: 01/15/2024

In certain makes of general motor vehicles there is a defect with the pcv system in which the system can freeze in cold temperatures which in turns causes excessive crankcase pressure in the engine, and can lead to a dangerous loss of motor power due to this defect. The dangers of this defect can be catastrophic to myself and others on the roadway as the loss of motor power can happen suddenly and can happen while the vehicle is being driven. General motors has released many service bulletins regarding this specific defect. The most recent service bulletin that was issued was gm January 2019 bulletin pip5093c, so they are aware of this dangerous problem in these vehicles. For my vehicle I have had a certified GMC dealership diagnosis the problem, and submit their findings to general motors. There were not any warning lamps, messages, lights, or symptoms signaling that there was a problem prior to the occurrence on January 15th, 2024.

44 Equipment problem of the 2022 GMC Terrain

Failure Date: 01/14/2024

45 Equipment problem of the 2012 GMC Terrain

Failure Date: 12/24/2023

My 4 cyl. Awd GMC Terrain has had excessive oil use which caused premature failure of the timing chain, loss of power/compression, blown engine, damage to exhaust manifold, cellinoids, and melted the catalytic converter. Its was a road safety, poor emissions due to failed catalytic converter. Headlights are too bright for oncoming traffic at night. Another road & safety hazard. Auto warranty is refusing to cover parts listed above caused by the timing chain and excessive oil consumption problems.

46 Equipment problem of the 2020 GMC Terrain

Failure Date: 12/18/2023

My backup camera in my 2020 vehicle has failed twice. Once was covered under manufacturer's warranty, and it then failed again 14 months later, which is not covered under warranty. As explained by the dealer, a parts warranty is 12 months if covered under manufacturer warranty and 24 months if paid for by the owner. Different warranties for the same part? additionally, there is a service bulletin out about this issue as many other owners are reporting the same issue. The camera parts are being damaged by "water intrusion". There is no rust or damage that would be contributing to this, thus it appears to be a manufacturing defect. There is no way I should have had to replace this part twice with only 40,000 miles on the vehicle. (first time at 24,000 miles, second time at 38,500 miles). I feel that the manufacturer should be fixing these as they know it is a widespread problem.

47 Equipment problem of the 2019 GMC Terrain

Failure Date: 12/18/2023

It began with showing "service brake assist" for about 2 weeks + then on Dec 18th 2023 around 10:30 as my fiancé was stopped at a stoplight and all of sudden when the light turned green she attempted to continue forward as traffic started to move only to stall stalled out before any movement could be achieve the battery was reading severely depleted and the vehicle would not function at all she was stuck in drive and could not put the vehicle in neutral or even park to even try to restart the vehicle, she could not even turn the steering wheel, roll down the windows, open the door, or anything. The only thing she was able to accomplish was opening the hood so an officer that had arrived at this time could give her a jump, the officer also proceeded to leave the negative cable on the battery terminal and disconnected the positive cable from the battery terminal which would have indicated a bad starter or depleted battery when the positive cable had been removed, which was not the case. She continued to where her appointment was and that is where I met her and took over vehicle to transport it home, driving with hazards on. I arrived at the house with no incident. Then at 4:45pm on the evening of 12/18/2023 while at the stoplight I had a similar issue occurred as I was going from a stationary position to a forward slowly accelerated speed gaining momentum where the vehicle wanted to stall out while I was stopped at a stoplight attempting to proceed forward. And then at around 10:20 pm while stopped at a stop sign a similar issue occurred as I was going from a stationary position to a forward slowly accelerated speed gaining momentum attempting to proceed forward. On Dec 19th 2023 around 10:00 am I test started the car by remote and it started up and then I turned it off, now it is showing that the battery is completely depleted at 1:26 pm.

48 Equipment problem of the 2018 GMC Terrain

Failure Date: 12/10/2023

I was driving my car December 10, 2023 when I was at a red light my truck completely shut down I could not reverse I could not put in drive I could not put in park I could not switch gears. I didn’t know what happened. I had to call a tow truck to get me home once I got home I got my car towed to a shop. Before my car was towed I contacted onstar. Onstar did a diagnosis on my car and it came back ecm which stands for electric control module. When my car was at the shop I got a tune up & the mechanic was able to start my car. Driving again on the date of December 15, 2023 it did it again and it said ecm. I was paranoid because I was on the expressway I had too get my car towed to the dealership. This is the second time that my car has did this. I keep all maintenance up on my car. I’m not understanding what’s going on. I feel like it should be a recall on this issue. It was very dangerous both times that my car stopped. Now yet again I’m waiting to see what the problem is. This is definitely a safety recall issue. I have a 2018 denali Terrain with only 71,000 miles I keep up with oil changes and maintenance on my vehicle. Who do I contact about this concerning scary situation, will it take for a person to die before this is is rectified. Someone please contact me or respond to this situation. So we can request for a recall on this serious matter.

The clips popped off or something happened and now the headliner is hanging and I can't see out the rear view mirror. It's a hazard for anyone sitting in backseat. I've had it in 2 different shops . Needs to be a recall because I've read several other people having this issue.

51 Equipment problem of the 2022 GMC Terrain

Failure Date: 08/03/2023

On Aug 3rd 2023 I was driving east on a michigan highway when the service transmission warning came across the dash then the car shut off while driving 60mph. When trying to steer the car to the side of the road I noticed the car was in park(this car is equipped with push button shift). The car shutting off made it very hard to steer. If the traffic was heavy this could have caused an accident. I do have a video of this happening.

52 Equipment problem of the 2023 GMC Terrain

Failure Date: 07/21/2023

The problem with this car that continues is that when driving over 65 miles per hour/ more or less, the driver side door rattles and shakes. It rattle and it looks like if the door wants to detach. It only happens on the driver side, not the passenger side. I put my arm on the arm rest, and my arm shakes and that is not ok. I am concern and want to know what can be done about it. I do not feel comfortable driving when this happens and its a new car, it should not have this problem. The problem started right after I purchased the car and I already took it to service it and they said it was the tires not having enough air, but that's not the case, cause it still doing it. I need to take it to service it again please advise what can be done about it and if they can find what the problem can be. Your assistance is very much appreciated. Thank you.

53 Equipment problem of the 2012 GMC Terrain

Failure Date: 07/20/2023

My lift gate has been failing since I bought it used from a local dealership. It's closed down on my mom's leg when she was situating luggage that she'd put in. It has tried closing on myself as well each time I opened it(4×) & when I tried to stop it by pushing up on it, it only forces itself down not up. This is very dangerous & had an old recall from gm motors due to the struts in the lift gate was faulty & made by stabilize whom had numerous lawsuits from other manufacturers due to injuries & deaths. The dealership refuses to fix it for free even though they knew the issue with it cause it was brought to their attention by their detail guy whom had it close on him as well. This a is major issue that needs addressed ASAP. And not at the expense of the owners but the manufacturers & dealerships that knowingly sell these autos that can be dangerous.

54 Equipment problem of the 2020 GMC Terrain

Failure Date: 07/16/2023

My 2020 Terrain is now at 33k+ miles, I have had repeated instances with my car not accelerating properly. I would be at a full stop try to start to accelerate and not move push down a little further on accelerator and start crawling forward. I would move approximately quarter mile before the vehicle would jerk and accelerate very quickly to a speed well over where it should go to. I. E. I know because I’m starting in traffic I’m not trying to take off at thirty but when the jerk happens I can be jolted to 40-45 mph. The other issue is people behind you don’t realize what’s going on and I have been hit almost twice thankfully they were able to avoid me by going around. No warning lights have come on. This last insistence not only could I not accelerate, but cruise did not want to turn on, the emergency brake didn’t want to work, and the air conditioner was loosing power. I plan on having an independent service center inspect the vehicle, my husband was able to repeat the issue so I’m sure they will also. The first incident was in may and I have had 5 but thankfully I don’t drive that much.

55 Equipment problem of the 2014 GMC Terrain

Failure Date: 07/15/2023

There's an oil consumption issue that requires you to constantly refill the engine with oil between oil changes. It's so bad that it causes buildup and eventually interferes with the timing. Causing significant, unacceptable repairs! now I'm forking out money for a constant issue that shouldn't exist! my car cut off in traffic! that's a major safety issue! I will provide costs of repair when I get the final estimate! my timing chain, tensioner and pistons may need to be replaced because of this issue!.

56 Equipment problem of the 2012 GMC Terrain

Failure Date: 06/16/2023

Drive side frame is rotted out which has allowed rear driver side control arm for the wheel to freely move. The passenger side is completely fine. Contacted gm and was told it has to be taken to a dealer to be diagnosed. It’s easy to see the issue I have pictures that can be provided. This car should not be rotted out frame was perfect 8 years ago with no rust and has been washed twice a week during winter to remove salt with undercarriage car wash.

57 Equipment problem of the 2022 GMC Terrain

Failure Date: 06/15/2023

Vehicle started stalling back in February 2023, service engine light started coming on and then we started getting a message that the sd memory card had been removed and this message has stayed on constantly along with the service engine light. I made an appointment to get the recalls fixed with the dealership that we purchased it from which is 50 miles away but was told the parts for the fuel pump and child restraints were not available at that time. They looked at the memory sensor card but could not find anything wrong and was told if the error message came back up to call them back, I know more got home and the message came back up so I called them back and they set me up with another appointment the following week. This time because the message only comes up randomly and it did not come up while I was there I was told nothing could be done but to call back when the message comes back and as soon as I got home it came up so I called them back, they made another appointment for the following week and this time the message came on when the tech drove it so they took out the sensor card and cleaned it and everything around it and said everything looks fine now but it still comes on, but was told due to them not having the parts for the fuel pump that we should take it to our closest dealership. On 6/15/2023 we took it to our local dealership and I was told they would need to order parts and the eta on it was 4 days out, they said they would call me when the parts came in, I waited until 6/22/23 and no one ever called me back so I called to check and the parts were still not in but would check on it and call me back, no one ever called and I still have not heard from anyone. The last time we took it up there the vehicle stalled, we almost got hit from behind and it kept dying and would barely start, it is now setting under my carport, we are afraid to drive it and I still have not heard from anyone. This all started in February 2023 and it is June now.

58 Equipment problem of the 2017 GMC Terrain

Failure Date: 06/10/2023

We have had many gm vehicles my husband worked at gm retired now. Our complaint is we have a GMC denali 2017 only 79000 miles on it. All upto date changes regularly all. Other like transmission oil changed all upkeep to date. Transmission needs rebuilt. We are in our 80’s and don’t beat up our cars. Replace or rebuild transmission 3500 to 4500 bucks. That is a lot of money for us. No longer covered. It shudders when you drive at any speed and feels so unsafe. Took it to gm garage and they couldn’t find anything wrong. No warning lights came on and we paid over 150 to have it checked out so with the shuddering getting worse and not feeling safe to drive we took it to a transmission shop and he took it out and said the shuddering was caused by something in the transmission. I have seen on google where gm is having a lot of problems in this area. We just need help with the repairs. Thank you. A retired gm worker lordstown, ohio donald pennington. Retired 1999 uaw 1112.

59 Equipment problem of the 2020 GMC Terrain

Failure Date: 06/04/2023

I was driving approximately 75mph on the interstate. 3 hrs into my trip I started feeling hot so I turned the a/c up. In my peripheral vision I saw orange and thought a car was beside me on fire. Immediately I realized it was my vehicle. I immediately slowed and came to a stop. I put it in park and opened the door. By the time I started to exit there were flames higher than the rear windows. A car that was behind me stopped. They said about a mile back there was a spark under the car by the rear tire. Then it went up in flames.

My vehicle keeps running extremely low in oil and not alerting me with any warning lights. My vehicle starts to shake like it is going to stall and the engine makes a rattling noise. This is a safety concern.

62 Equipment problem of the 2012 GMC Terrain

Failure Date: 05/20/2023

The timing chain is failing on my 2012 GMC Terrain. It’s dangerous to drive and it started without warning (to me). It’s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? many thanks.

63 Equipment problem of the 2018 GMC Terrain

Failure Date: 04/15/2023

Driving home from our local town 4/15/2023, the brake pedal became to hard to push down. Check engine light came on as I got to my driveway, and that is 1 mile from the main road. My kids were scared to tears as was my girlfriend. Run a scan and dtc p0557. Come to find the vacuum pump on the top drivers side of motor is the part that is bad it broke inside the valve cover. Looking up the issue and find out it is a known problem and no recall. I have kept the parts and all receipts for the repairs, I have to do myself cause the repairs are way to much for me to pay out of pocket. This is a serious issue for this car and year and GMC needs to address the issue. Why has nothing been done yet??? I am making payments on this car with no warranty for the car so I'm stuck fixing the car. But GMC knows that this is a problem and does nothing?!? I remember when american cars were good cars what happened to that time ?? and what happened to company's being responsible for the product they put out to customers? guess that time is gone, I won't buy another american car again, unless it's a old detroit built car.

64 Equipment problem of the 2020 GMC Terrain

Failure Date: 04/09/2023

On 4/10/2023, I took my vehicle to a local GMC dealership because it was stalling and didn't have any power. Upon accelerating the vehicle it would stall and take off at a high speed. The dealership has had my vehicle periodically from April 2023 and it presently sets at the dealership because they ain't getting a code, but after the dealership drove the truck for over 200 miles, they were finally able to duplicate the stalling yet are not able to diagnose the problem!! this vehicle is very dangerous to be on the road and I have almost gotten hit twice and I'm not driving the vehicle anymore at this time. I have previously reached out to you all and I would be most thankful if you could get in touch with me. Thank you.

65 Equipment problem of the 2022 GMC Terrain

Failure Date: 04/06/2023

April of 2022 I purchased this car brand new. January of 2023 this car started to have a musty/mold smell. I took it into the dealership in late February and inquired if this was a reported problem. I did as they dealership said and replaced the cabin filter. The cabin filter was black at 9,700 miles. It smelled horrible. On April 6, 2023, I took my car into the dealership to resolve this smell. It was discovered that the the cowl inside the firewall on the drivers side firewall had several holes and an incorrectly applied seam. It was also discovered that the drivers side sunroof drain was also disconnected. This was was full of mold. They replaced the entire interior of my car which took until June 28th. I expressed I did not want this car back for fear of mold, I had already been sick and had no idea why. Once I got into a dealer car, I quit coughing. The dealership cannot guarantee me that they got all of the mold in the car, it still has an odor in it. I have went through the claims process with gm and they have refused to buy back my car, based on my claim I am worried about my health. This car had $12,000 in repairs to it. I was promised verbally by the district manager of after market sales that my car would be bought back. They backed out on the deal and told me they cannot buy it back for destruction. I have great concerns about my cars safety with the mold being so large. They cannot guarantee me the mold is completely gone as told me to by the service manager. Therefore, this would include the safety of others that travel in my car, to include children and older adults. This problem started in manufacturing and was acknowledged by the dealership as such. It was a defective car when it arrived on the lot.

67 Equipment problem of the 2013 GMC Terrain

Failure Date: 01/16/2023

I have almost been in 3 accidents. My 2013 Terrain has stalled while driving. . Cut off at lights. Engine reduced while driving and massive oil leak that gas caused timing chain and engine failure. I have read other complaints, and this is sad GMC has been allowed to get away with this. These engines are dangerous and need to be replaced before someone looses their life.

68 Equipment problem of the 2017 GMC Terrain

Failure Date: 12/30/2022

The rear main seal is out, which is causing an oil leak. The intake manifold failed because the pvc system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. (pvc pipe is freezing over in cold temperatures which causes the failure of the main seal to blow out subsequently leading to additional major issues and parts failure. This issue has occurred in an overwhelming amount of vehicles. ).

69 Equipment problem of the 2020 GMC Terrain

Failure Date: 12/29/2022

My service brake assist light came on and then within seconds my vehicle then said engine power has been lowered and my vehicle pretty much shut down no steering no brakes couldn't do anything. Took it into the repair shop and my vacuum pump has shattered and now damaged my camshaft. I am aware there's been many other vehicles recalled with gm's vacuum pumps and I'm not sure why my year and model has not been included when it's doing the same thing and not to mention I have seen countless other cases of people saying same things happen to them with their GMC Terrains.

70 Equipment problem of the 2013 GMC Terrain

Failure Date: 12/27/2022

I was driving my 2013 GMC Terrain to a friends house, I stopped at a stop light, when I picked up speed, the car stalled and wouldn't get up to speed. Eventually, it did pick up speed. I went to turn into her neighborhood and the same thing happened. Trying to get to the destination, I continued into the neighborhood. I stopped at a stop sign, and when I tried to accelerate, the car died. No indicator lights were engaged. I turned the car off and waited a minute or so and turned it back on. I got to her house, and charged my battery and drove home without issue. The next day, I went to have my battery checked and they alerted me to a horrible oil leak. I had the car towed to the dealership. The next day, the dealership told me that GMC would specifically have to look at the vehicle to diagnose. I had the car towed to my trusted mechanic and he told me the rear main oil seal blew out and found a service bulletin regarding this issue #14882. I made an appointment with the dealership only to find out that this isn't covered under the bulletin, because it expired in November of 2022, and it's not covered under my warranty. The warranty company stated, "if there isn't evidence of moisture in the pcv it would be covered, but since it's a known issue and a consistent problem with the vehicle, it's not covered. " so, my only choice is to pay out of pocket for a defective part that will continue to break and cause the rear main oil seal to blow out of the car, potentially putting me and my 9 year old daughter at risk, because GMC isn't acknowledging this issue and recalling the faulty part that is the root of the problem and has been widely reported. There is also a class action lawsuit that is currently open and ongoing (case 2:22-cv-10785-mag-jjcg) which is trying to hold GMC responsible for not recalling the part sooner - when they were made aware of it - putting thousands of consumers at risk. It's also fraudulent for this information to not be disclosed at point of sale.
