The compact SUV segment is highly competitive in the automotive industry, with several top-rated models that have gained incredible popularity and consumer loyalty. Renowned models in this segment include the Honda CR-V, Toyota RAV4, Ford Escape, and Mazda CX-5, among others. As such, simply producing a competent SUV isn’t enough. Unfortunately, some crossover models do just that and simply exist in the market – including the GMC Terrain.

While it’s likely not going to top anyone’s list of the best crossover in the market, there’s much to love about the GMC Terrain. It offers a roomy interior for a compact SUV, composed ride and handling, and an intuitive infotainment system. However, if you’re competing with the likes of the Honda CR-V and Mazda CX-5, you better bring your A-game – this is where the GMC Terrain came up short. In a vacuum, the Terrain can be good to decent, but compared to its rivals, it doesn’t offer nearly as much value.

If you’re interested in a used unit, you’re probably asking: how long do GMC Terrains last? Older and high-mileage Terrains can provide a good bang for your buck, but potential buyers should know about their lifespan. For today’s post, we highlight the longevity of the GMC Terrain, how many miles it can last, and whether it’s a sound investment for used car buyers.

Just How Reliable is the GMC Terrain?

How long do GMC Terrains last? Before we get to that, let’s talk about the SUV’s reliability. As you might know, reliability and longevity go hand in hand. After all, a car with quality parts undergoes thorough testing and has a track record of fewer problems, and is more likely to last a long time and serve its owner well.

Unfortunately, the GMC Terrain isn’t known for its reliability. According to RepairPal, the GMC Terrain has a reliability score of 3.5 out of 5.0, but it belongs in the near-bottom with 22nd ranking out of 26 compact SUVs. In addition, the Terrain has an average annual repair cost of $558, slightly higher than the average of $521 for compact SUVs. On the other hand, WithClutch gave this SUV a dismal score of 35 in reliability, which is considered “not very reliable.”

Meanwhile, people over the web seem to have mixed opinions about the Terrain’s reliability. Based on TerrainForum.net, some users have expressed concerns about the GMC Terrain’s reliability, especially in specific model years; others have had positive experiences with the vehicle. One owner advised avoiding the 2.4L engine from the 2010-2012 model years and suggested considering models from 2015 or later for better reliability. They also mentioned that the V6 Terrains from 2013-2017, equipped with the 3.6L V6 engine, have been very reliable.

Overall, the GMC Terrain’s reliability can vary from one model year to the next. In fact, some Terrain years are best avoided because of severe reliability woes. For instance, the 2011 GMC Terrain suffered from engine issues such as stalling and excessive oil consumption.

How Many Miles Can a GMC Terrain Last?

Despite the questionable reliability, the GMC Terrain can reach impressive mileage numbers based on available information and consumer accounts. GMC is known for its rugged vehicles, and that ruggedness and durability have worked in the Terrain’s favor. On average, a GMC Terrain can last between 200,000 to 220,000 miles, provided it receives regular maintenance and timely repairs.

People all over the internet have also shared their high-mileage Terrains with some impressive results. A user from the Terrain Forum mentioned that they own a 2011 GMC Terrain 2.4L with 191,000 miles. The underside of their vehicle is starting to rust, and there’s a small exhaust leak in the manifold. Despite these issues, the engine runs well. Another user shared their practice of driving their Terrain until they reach 222,222 miles but also mentioned that they wouldn’t take long trips with cars nearing 200,000 miles. In summary, while many users have had positive experiences with their GMC Terrain, some have faced issues, especially as the miles stack up.

With that said, the Terrain needs regular maintenance and timely repairs to reach these numbers – probably even more so than other vehicles in its class.

How Many Miles are Too Many for a Used GMC Terrain?

Used GMC Terrains require careful mileage consideration, but it doesn’t tell the whole story. Check out these tips on how to approach different mileage ranges when buying one:

  • General Tips: Always ask for a vehicle’s maintenance records, indicating if the vehicle was well-maintained. This includes regular oil changes, fluid replacements, and other routine services. Always take the vehicle for a test drive. Listen for any unusual noises, and pay attention to how the vehicle shifts, accelerates, and brakes.
  • Under 50,000 Miles: This used vehicle has relatively low mileage and is likely still covered under the manufacturer’s warranty. It’s important to confirm that all routine maintenance, such as oil changes and tire rotations, has been completed.
  • 50,000 to 100,000 Miles: For used vehicles in this range, like the Terrain, be extra cautious as it may no longer be under warranty. Check for wear on brakes, tires, and suspension. Ensure major services like transmission fluid changes and spark plug replacements have been done.
  • 100,000 to 150,000 Miles: When a Terrain falls into this range, it is essential to check if any significant components need replacement, such as the timing belt or water pump. Also, look for any signs of rust, particularly if the vehicle comes from an area that uses road salt. Additionally, ensure the vehicle doesn’t burn excessive oil, as some Terrain models are known to have this issue.

Is a Used GMC Terrain a Worthy Investment?

However, due to the Terrain’s not-so-stellar reliability, be wary of high-mileage units over 100k miles.
