What Makes These GMC Terrain Years is Worth Avoiding?

If you’re in the market for a GMC Terrain, there are a few things to check for.

These will not only help you choose a better pre-owned car, but they will also educate you on the risks associated with buying a GMC Terrain.

According to my research, the following are some of the top reasons to avoid certain years:

  • Engine troubles
  • Transmission failure
  • Excessive Oil consumption

1. Engine Troubles

Customers’ most common issue, especially with the 2010 and 2011 versions, was engine problems. Engine issues may be costly, and if not addressed quickly, they can also be deadly. For people who purchase a GMC Terrain, a malfunctioning engine is a major headache.

The other engine problems included:

  • Stalling and stopping the engine
  • The engine that shuts down while driving
  • Engine light constantly on
  • Electrical problems

These are a few engine-related concerns that drivers have reported with some of the vehicles listed above. For people on the road, this situation may be both dangerous and costly.

A car with a malfunctioning engine is a ticking time bomb for both you and other drivers on the road.

It’s not worth the risk, so steer clear of vehicles with engine issues.

2. Transmission Failure

Transmission failure is the most common secondary issue with the GMC Terrain model years to avoid.

Transmission problems may be just as costly and inconvenient as engine issues. These might keep you from getting where you need to go during the day.

  • General transmission failure
  • Lack of proper reset after fix
  • Powertrain failure
  • These are some of the transmission failure issues.

No matter what you want in a car, none of these are likely to appeal to drivers.

Even with a used automobile, you’re shelling out a substantial sum. Get a GMC Terrain that is worth the money you spent on it.

3. Excessive Oil consumption

Excessive oil consumption is the third-worst complaint about the GMC Terrain, this time for the model year 2010.

Four of the 15 owners who filed complaints had their engines replaced, while the other two had their engines refurbished. The fixes are covered by the same class-action lawsuit that addresses the 2011 model year’s high oil usage.

One owner mentioned, “Had nothing but problems since I drove it off the lot.” Another said, “Thank you, General Motors. I’ll never buy/recommend any of your vehicles again.”

The average cost of the repairs was $4,020. The problem was regarded as “very terrible” by the owners, who gave it an 8.7 severity rating. On average, the problem began to manifest at 94,400 miles, which is a little later than the identical issue in the 2011 Terrain.

Between 2010 and 2013, engine problems remained the most common complaint with the GMC Terrain. The issues were substantial, and the owners had to spend a lot of money on repairs.

Since then, the number of complaints has dropped. Interior accessory issues are currently the most common complaint category in 2014.

4. Electrical problems

The electric system in the GMC Terrain has been noted to be problematic.

This is a well-known problem that has existed for years, but if you are experiencing these symptoms, it may be time to have your automobile looked out.

It can, among other things, cause the battery to deplete fast and not charge correctly.

The National Highway Traffic Safety Administration (NHTSA) began looking into allegations of unexpected acceleration in GMC Terrains from 2010 to 2012.

According to the research, these models’ accelerator pedals had a flaw that enabled them to move abruptly, potentially causing vehicles to accelerate accidentally. As of June 2013, General Motors had rectified this issue.

Which Years are Safe to Buy Used?

Based on the number and severity of user-submitted complaints about each year’s model, as well as the average mileage at which problems arise and the cost to fix them, I’ve compiled a list of which used GMC Terrains are safe to buy used.

Following years of GMC Terrain have fewer problems, and the ones that do exist are usually less significant and less expensive to fix than the models mentioned below.

Following are the greatest years for the GMC Terrain:

  • 2016
