Gmc Terrain problems

The GMC Terrain is a crossover SUV by American manufacturer General Motors under its GMC marque. Sharing its platform with the Chevrolet Equinox, the first-generation Terrain was built on GM's Theta platform, while the second-generation model is currently built on the Delta platform. The Terrain is the smallest GMC vehicle, slotted below the Acadia. It also indirectly replaced the Pontiac Torrent which was typically sold via the same dealerships prior to General Motors dropping the Pontiac brand.

First generation (2010)

The 2010 Terrain debuted in April 2009 at the New York International Auto Show, introduced as a replacement for the Pontiac Torrent, which ended production after GM shut down the Pontiac brand in 2010. Although the preceding Pontiac Torrent had the same Theta platform, the Torrent was a rebadged version of the original Chevrolet Equinox from 2005 to 2009, while GM decided to differ the look of the Chevrolet Equinox with its 2010 Terrain and still use the Theta platform. Early 2010 models had the GM Mark of Excellence logo applied on the sides of the vehicle.

The Terrain initially came in SLE and SLT trims. For the 2013 model year, a Denali trim was added, featuring additional chrome trim and slightly improved interior quality, the 3.6-liter SIDI V6 that is shared with the 2012 Cadillac SRX, and firmer front struts. The Denali also offers cross-traffic detection, blind-spot warning, and a power passenger seat as options. A low-end SL trim was added for 2015.

Common Gmc Terrain problems

The GMC Terrain, a mid-size crossover SUV, has been reported to have several common problems based on complaints from its owners. These issues range from engine troubles, transmission failure, excessive oil consumption, faulty airbags, and HVAC system woes.

One of the most prominent issues reported is engine troubles, with the 2011 GMC Terrain having the most overall complaints, particularly for excessive oil consumption.

Transmission failure is another significant problem, which can be as expensive as engine failures to deal with and twice as annoying. Transmission issues can prevent you from going anywhere you need to in your day. Some of the transmission failure issues included general transmission failure, lack of proper reset after fix, and powertrain failure.

Excessive oil consumption is a common problem in the GMC Terrain models. Instead of burning through oil regularly, this vehicle consumes it extensively. You can find your vehicle burning out fast if you’re not careful. There are specific model years, such as the 2010 and 2011 options, that face excessive oil consumption, which can lead to more significant issues if not addressed promptly.

Faulty airbags are also a concern in some GMC Terrain models. For instance, several owners of the 2017 GMC Terrain complained about airbags that tend to malfunction. The airbags failed to deploy in the event of a collision or crash, which is obviously a massive safety risk. You can’t afford to ignore this issue since there were reports of injuries because the airbags didn’t activate due to an actual accident.

HVAC system woes are another common problem in several Terrain model years. Some owners shared stories about their heater blowing cold air instead, which can be unbearable under extreme conditions. GMC had to release numerous service bulletins to address the issue of malfunctioning heating and cooling systems. Other symptoms of a faulty Terrain HVAC system include water leaks coming from the climate system, strange odors, and reduced heating/cooling performance.

These common problems in the GMC Terrain models can lead to significant expenses and safety risks. Therefore, it is crucial to be aware of these issues and consider them when purchasing or maintaining a GMC Terrain.

If this happened during normal rush our, my kids and I would have been sandwiched between two cars. Fatal flaw that clearly GMC already knows about. The Terrain should be included in the recall.

Gmc Terrain 2022
  • Date Of Incident: 2024-10-09
  • Date Complaint: 2024-10-16
  • VIN: 3GKALMEV0NL
  • Components: ENGINE,FUEL/PROPULSION SYSTEM
  • Summary: My check engine light came on and I got it hooked up to get the code of P0171 - Upon checking it was different things like O2 sensor the Mass Airflow sensor, fuel pump issue etc. I have been having issues with slight hesitation during acceleration, some jerking when slowing down (not hitting the brakes). Now the check engine light was on for one day the next day it was off. I did some research and found an article that stated that GM is issuing a safety recall for 2021 and 2022 GMC terrain due to a problem with the fuel pump module failing, not enough fuel to the engine and creating stalling risk. This was from January of 2023. It also said GM notified the National Highway Traffic Safety Administration of the upcoming recall on Jan 19th 2023 and was still pending as of Feb 2023. Also stated that GM has not yet conducted actual repairs to correct the issue. My truck, I bought it brand new on Jan 20th 2022, only 23,450 miles on it. The problem literally came out of no where a week ago. The hesitation, not being able to accelerate is very dangerous when I'm on the road, I could not get the check engine light checked out professionally because the next day it was off and I was informed that they could not do a proper diagnostic if there is no light on. Obviously there is an issue with the fuel system and I really want this checked out and possibly replaced. Not to mention my gas is also going very fast now.

Latest negative Gmc Terrain car reviews

  1. Mckenna Hansen 2025-08-03

    Vehicle year: 2012

    After driving 99K miles, my car needed $1500 in repairs. Although GM said they would warrant the repairs for a year, unfortunately, the car broke down again after fourteen months, which was very frustrating. The cost of the repairs was more than the trade-in value of the car, so I decided to buy a 2018 Santa Fe instead. I am now waiting for my other GM product to do the same, but in the meantime, my retirement dream car has shifted from a Camaro to a Mustang. #whygoback?

  2. Dante Stamm 2025-08-02

    Vehicle year: 2023

    I have owned my brand new 2023 Denali Terrain for 6 weeks now, and unfortunately, the radio/sound system has only functioned properly for 1 day (the first day). Despite having taken it to the shop a couple of times, I have been told that it is awaiting a software update and there's nothing that can be done. As a confident car owner, I believe that this is unacceptable for a brand new car. Furthermore, I was surprised to learn that this is a 'known GM issue' which should have been disclosed at the time of purchase.

  3. Monte Fritsch 2025-07-26

    Vehicle year: 2017

    Consider buying a six cylinder instead! This vehicle has a great look, but the four cylinder option may not be enough for you. During the test drive, I noticed that when merging onto the freeway and pressing the gas pedal firmly, it makes all of the right sounds but doesn't actually do anything. However, the interior is appointed fairly well and everything is easy to work. The seats are comfortable on long rides. It is a great vehicle for driving around town, but may not be the best option for the freeway. I traded a Honda Pilot in for this Terrain, and while it has a smaller turning radius, I rate the drivability lower. Overall, it's a good car, but consider your needs before making a decision.

  4. Dion Ziemann 2025-07-26

    Vehicle year: 2011

    This base Terrain is rated at 32MPG highway, but actually gets 25 highway in ECO mode, which inhibits performance. The issue has been reported to the dealer in Marianna, FL, but no service visit has been scheduled yet. It is unclear why the vehicle is not performing as expected on mostly level roads in Florida.

  5. Jerald Schumm 2025-07-23

    Vehicle year: 2018

    Hi there! I hope you're doing well. I wanted to reach out because I leased a car about 9 months ago and have been experiencing some issues with the dashboard. Despite going back and forth to the dealer, the problem hasn't been resolved and it's starting to get frustrating. I was wondering if anyone else has experienced this issue and if you have any advice on what I should do next? Thank you so much for your help!

    For having a 4 cylinder engine, you have adequate power to pull a utility trailer loaded with a load of dirt or gravel with little laboring of power. You can get anywhere from the low to mid 20’s around town driving all the way to the upper 30’s mpg on the highway driving.

  2. Saul Lockman 2025-08-01

    Vehicle year: 2019

    It's been a year since we purchased our 2019 Terrain. We only had to bring the car back to the dealer once for an oil change and tire rotation. We are extremely satisfied with our purchase because the car is very dependable and easy to get in and out of. As we get older, this could be a problem when buying a low car that makes access difficult.

  3. Eugene Harvey 2025-07-25

    Vehicle year: 2016

    This car would be almost perfect if it had rear air conditioning. We often have to freeze in the front to keep our passengers or our little dog from getting too hot in the back seat. Dual controls would be appreciated as we constantly fight over the temperature. Additionally, the car is too low to the ground and has a plastic wrap around border on the bottom, which means you have to be very careful when parking to avoid hitting parking stops or curbs. It's not suitable for off-road driving on rough terrain or steep driveways. However, the gas mileage is excellent, making it perfect for traveling. The seats go way back in the front and the back seat is adjustable, making it comfortable even for very tall people. It's easy to get in and out of because the seats aren't as low as a car. Although it's not a Subaru Outback type vehicle, it's still a great car for paved roads. The driver's side can be noisy on most roads, but it's tolerable. The back-up camera is a great feature. We wish we could have afforded the AWD, but so far, we haven't had any problems with only FWD. We did have an issue with the power steering on our second trip, and we had to have the entire front end replaced. Unfortunately, the dealer in another state wouldn't fix it, and we had to drive it back to our state without power steering to get it repaired. Despite this, the car has worked fine ever since. We've had great experiences with our local dealer for maintenance.

    I hope this message finds you well! I wanted to share my experience with my 2021 GMC Terrain. As of today, April 19/2023, I still own my Terrain that I purchased in November 2020. I have been extremely pleased with my purchase as it has not given me a single issue so far. The 1.5L Turbo is good, but I must say that the 2.0L Turbo is even better! The Terrain is a very well thought out vehicle, with features such as the back seat that flips flat at the push of a button and easily clicks back into place. The seats are at hip height, which at 71, makes them very easy to slide in and out of. The front bucket seats are fairly comfortable with many power adjustments, although they could use another 1/2I don't find the road noise too bothersome, but that might be because I always have Talk Radio on. I completely agree that a 2.0 Turbo would be a better engine option. I previously owned a 2018 Terrain Denali with the 2.0L and it felt like a rocket when I hit the gas. I've had my 2021 for 31 months now and have driven 21,530 miles without a single issue. However, there was one moment where I thought, 'what were they thinking?' - the screw for the driving compartment air filter is a 5.5 mm! I did change that filter at 18,000 miles even though the manual called for 30,000 miles. It's such an odd and hard-to-find size. I've been changing the oil and filter every 5,000 miles and rotating the tires. I would love to see the same vehicle but 10-12 inches longer and maybe 4-6 inches wider to fit a more beefy seat like the Tahoe has. Other than that, I will most likely buy another Terrain and definitely if they bring back the 2.0L Turbo.

    Hello! Thank you for sharing your experience with the 2012 STL-1. It's great to hear that you've had such a positive experience with the car, even after 119,000 miles! It's also good to know that the one check engine light issue you had was a minor repair that didn't cost much. Your approach to driving and maintenance seems to have paid off, as your fuel mileage is quite impressive. It's unfortunate that the EPA fuel mileage estimates can be misleading, but it's good to know that your dealership was honest about the findings. It's also important to note that not everyone has the same driving preferences, so it's understandable that some people may have complaints about certain aspects of the car. It's great that your dealer allowed you to test drive the car before purchasing it, and it's good to hear that you're still pleased with your Terrain after all this time. Thank you again for sharing your experience, and we wish you all the best with your car!We've had to spend $3000.00 on an engine rebuild at 141,000 miles, but the car runs great afterwards. Despite the timing chain issues that the 4-cylinder engine is known for around 85,000 - 100,000 miles, we're still very happy with it! The only downside is how quickly the resale value drops. Other than that, we have no real complaints.
