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 that necessitate avoiding certain years:

  • Engine troubles
  • Transmission failure
  • Excessive oil consumption

Engine Troubles

Early versions of certain vehicles, particularly the ones from 2010 and 2011, were known to have experienced serious engine issues. Such malfunctions can be costly and, if left unaddressed for an extended period, 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 is constantly on

Maintaining a vehicle with a reliable engine should be paramount to all.

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 the bag, 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.

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.
