Investigating the issues of GMC Terrains over various years, it has become clear that the engine is a common concern. Analyzing each year’s problems individually can provide better insight into what may be causing them.
2010 GMC Terrain Problems
The 2010 variant of the GMC Terrain has been met with two major complaints: engine and transmission problems. Reports have surfaced that the engine consumes excessive oil, producing noise when the vehicle is started and erratic power delivery. Transmission failure is also a common issue in this model year, as stalls of varying intensity can occur without warning. Together these issues create a high ownership cost for owners, making daily tasks difficult to complete.
2011 GMC Terrain Problems
The 2011 variant of the GMC Terrain has been identified as having various issues. These issues range from serious vehicle failures, such as engine and transmission problems, to seat belts and steering malfunctions. Reports indicate that the engine stalls or shuts down during driving, with the check engine light flashing often; excessive oil consumption is also reported in some vehicles. Moreover, transmission failure is particularly common in this model year’s Terrain. Additionally, exhaust system defects have been observed; specifically, cracks developing on the exhaust manifold and catalytic converter malfunctioning with exhaust fumes entering the car’s cabin.
2012 GMC Terrain Problems
The GMC Terrain has received many engine complaints and problems, even three years into its production. Despite this, the manufacturer has not addressed these issues. The 2012 model consumes high amounts of oil and misfire and fails with its rear main seal. Accessories have been reported to malfunction, such as lights dimming in the console and door areas, while OnStar navigation may be inaccurate. Electrical problems include the engine shutting off intermittently or radio services, Bluetooth technology, and other inaccessible functions.
2013 GMC Terrain Problems
GMC Terrain seems to be experiencing increasing engine and transmission problems yearly, including the main seal blowing up, reduced engine power, and sometimes a blown engine. Unfortunately, It has also become common for the vehicle to suffer excessive oil consumption.
Additionally, transfer cases have been known to break down regularly — which can lead to repair costs of over $4000. There is also reported vibration during acceleration that contributes to below-average performance from this vehicle model.
2014 GMC Terrain Problems
The 2014 variant of the vehicle is known to have several mechanical issues, such as the engine frequently shutting down while being driven and consuming excessive oil. The PCV Valve also often breaks down, with repair costs reaching up to $1800. On top of this, various accessories may experience malfunctions; for example, dash display lights going dim, the radio not working properly, and the stereo system abruptly shutting off. Additionally, reports indicate improper shifting due to seal breakdowns causing the car to roll back when parked.
2015 GMC Terrain Problems
Engine problems have been a major issue recently, with this year’s excessive oil consumption problem particularly problematic. Additionally, the variant has had reports of stalling while driving and a blown real seal on the motor. Windows and windshield issues are common, with wipers often stopping working unexpectedly. Accessories such as radios and cameras can go black or not work, while seats are uncomfortable and heated seats frequently cease functioning properly. Lastly, the liftgate may not stay up in some cases.
Most Common Problems Of GMC Terrain?
When considering a GMC Terrain, it is essential to research and be aware of the risks and potential issues of buying one. Knowing which models to avoid can help make an informed decision while giving the buyer a better understanding overall.
Research has revealed three major problems which necessitate avoiding certain years.
- Engine troubles
- Transmission failure
- Excessive oil consumption
1. Engine Troubles
Early versions of a certain vehicle, particularly the ones from 2010 and 2011, were known to have experienced serious engine issues. Such malfunctions can be costly to repair; if left unaddressed for an extended period, they can prove fatal. This poses a considerable amount of stress on any vehicle owner who is saddled with such an issue. Quick action and proper maintenance are essential to avoid disastrous consequences.
Other engine problems include:
- Idling and inconsistent power delivery of the engine
- The engine that shuts down while driving
- The engine light constantly on
Maintaining a vehicle with a reliable engine should be paramount to all.
2. Transmission Failure
Transmission failure is a serious issue that requires attention and consideration. If left unaddressed, it can lead to expensive repairs or the need for complete replacement. Common transmission issues include such problems as difficulty shifting gears, slipping out of bag, trouble accelerating or slowing down, and others. Taking preventative measures and staying up to date with maintenance checks can help reduce the risk of transmission failure in the future.
- General transmission failure
- Lack of proper reset after the fix
- Powertrain failure
Buying a used automobile can be expensive. It may require a large financial investment to acquire a secondhand vehicle, which often comes with issues that aren’t desirable for the driver. Consequently, weighing the cost of buying a used automobile versus investing in a new one before deciding is important.
3. Excessive Oil Consumption
Excessive oil consumption has been a persistent problem with the GMC Terrain, particularly in its 2010-2015 variants. This issue has become so notorious that it can be called a vehicle feature. As many as 15 owners filed complaints against GM due to this issue, and four had their engines replaced while two had them refurbished.
The average cost of the repairs was $4,020, and consumers rated it 8.7 on a severity scale out of 10, with an average starting mileage of 94,400. During this period, engine problems were the most common complaint related to GMC Terrains. Still, over time, manufacturers implemented fixes in later versions, which decreased the number of complaints significantly after 2014, when interior accessory issues became the main cause of consumer complaints.
Which Years Are Safe To Buy Used?
Considering the severity of complaints, frequency of issues, and cost of repairs, a selection has been made for safe buying options in used GMC Terrains. Variants released in recent years are reported to be less problematic, with fewer expensive repair costs.
The best years to buy a GMC Terrain:
- 2016 GMC Terrain
- 2017 GMC Terrain
- 2018 GMC Terrain
- 2019 GMC Terrain
- 2020 GMC Terrain
- 2021 GMC Terrain
GMC Terrain has seen great years and offers even more as time progresses. It’s essential to do your research when deciding which year of GMC Terrain to buy so that all money spent is well worth it. Considering what each year provides, and any fixes implemented will help avoid costly repairs or additional charges down the line.
Considering the various points of reference connected with each model year of the GMC Terrain, it is important to determine what features and problems are most pertinent when deciding which vehicle best suits one’s needs. With this knowledge in hand, individuals can confidently select their ideal car with confidence.
