2019-2020 Generally positive reliability ratings; improvements made to address initial second-generation issues. Minor electrical problems, occasional infotainment system issues.
2021 High owner satisfaction and reliability ratings; considered one of the better years for the second generation. Few reported problems; generally a reliable year.
2022-2023 Continued high reliability and owner satisfaction; minor updates and improvements. Very few reported issues; generally considered solid choices.
2024 Too early to definitively assess long-term reliability, but early reports are promising. Based on previous years, expect high reliability. Monitor for any emerging issues in the first few years of ownership.

Detailed Explanations

2010-2012: These early models are generally considered the least reliable due to significant engine problems, particularly excessive oil consumption. The 2.4L Ecotec engine in these years was prone to oil burning, which could lead to engine damage if not carefully monitored and addressed. Timing chain issues were also common, requiring costly repairs.

2013: While the 2013 model saw some improvements, it still inherited many of the engine-related problems from the earlier years, making it a less desirable option compared to later models. Although the frequency of issues decreased, the potential for expensive repairs remained a concern.

2014-2017: These years represent a significant improvement in reliability and owner satisfaction. GMC addressed many of the engine issues plaguing the earlier models. While some instances of oil consumption might still exist, they are far less common. These years offer a good balance of features, reliability, and affordability.

2018: As the first year of the second generation, the 2018 Terrain introduced a new design and engine options. However, being a first-year model, it experienced some initial teething problems. Infotainment system glitches and transmission hesitation were common complaints. Potential buyers should be aware of these potential issues and carefully inspect any 2018 model before purchasing.

2019-2020: These years saw improvements based on feedback from the 2018 model. GMC addressed many of the initial issues, resulting in higher reliability ratings. While minor electrical problems and occasional infotainment system issues were still reported, they were less frequent than in the 2018 model.

2021: The 2021 GMC Terrain is widely regarded as one of the best years for the second generation. It boasts high owner satisfaction and reliability ratings. Few problems have been reported, making it a dependable choice for those seeking a used Terrain.

2022-2023: These models continue the trend of high reliability and owner satisfaction. GMC has made minor updates and improvements over the years, resulting in a refined and dependable vehicle. Very few issues have been reported, making them solid choices for buyers.

2024: It's too early to definitively assess the long-term reliability of the 2024 GMC Terrain. However, based on the improvements made in recent years, early reports are promising. Buyers should monitor for any emerging issues in the first few years of ownership, but the outlook is generally positive.

Key Issues to Watch Out For (All Years)

Even the best years of the GMC Terrain can experience certain issues. Here are some common problems to be aware of:

  • Excessive Oil Consumption: Primarily affects 2010-2017 models with the 2.4L Ecotec engine. Regularly check oil levels and monitor for signs of oil burning (e.g., blue smoke from the exhaust).
  • Timing Chain Problems: Also more common in 2010-2013 models. Symptoms include a rattling noise upon startup and potential engine misfires.
  • Water Pump Failure: Can occur in any year, but more prevalent in older models. Look for coolant leaks and overheating.
  • Transmission Issues: Some owners have reported transmission hesitation or rough shifting, particularly in the 2018 model.
  • Infotainment System Glitches: Common in the 2018 model but can occur in other years. Symptoms include freezing, slow response times, and connectivity problems.
  • Sensor Failures: Various sensors can fail, leading to warning lights and potential performance issues.
  • Air Conditioning Problems: Some owners have reported issues with the air conditioning system, particularly in older models.

Factors to Consider When Choosing a GMC Terrain

Beyond the year model, several other factors should influence your decision:

  • Mileage: Lower mileage generally indicates less wear and tear.
  • Maintenance History: A well-maintained vehicle is more likely to be reliable. Ask for service records and check for regular oil changes and other preventative maintenance.
  • Vehicle History Report: Obtain a vehicle history report (e.g., Carfax or AutoCheck) to check for accidents, title issues, and other potential problems.
  • Test Drive: Thoroughly test drive the vehicle to assess its performance, handling, and overall condition.
  • Inspection: Consider having a trusted mechanic inspect the vehicle before purchasing it.

Trim Levels

The GMC Terrain is available in several trim levels, each offering different features and amenities. Common trim levels include:

  • SL: The base trim level, offering standard features.
  • SLE: Adds more features and comfort options.
  • SLT: Offers a more luxurious experience with upgraded materials and technology.
  • Denali: The top-of-the-line trim level, featuring premium materials, advanced technology, and exclusive styling.

Consider your budget and desired features when choosing a trim level. The higher trim levels typically offer more features but also come with a higher price tag.

Engine Options

The GMC Terrain has been offered with various engine options over the years. The most common engines include:

  • 2.4L Ecotec Inline-4: Offered in earlier models (2010-2017). Known for its fuel efficiency but also its oil consumption issues.
  • 1.5L Turbocharged Inline-4: Introduced in the second generation (2018-present). Offers a good balance of power and fuel efficiency.
  • 2.0L Turbocharged Inline-4: Available as an upgrade option in some years. Provides more power and performance.

Consider your driving needs when choosing an engine. The 1.5L turbo is generally sufficient for most drivers, while the 2.0L turbo offers more power for those who need it.
