Reliability & Common Issues

The GMC Terrain, while generally reliable, has had its share of reported issues across both generations. Understanding these potential problems can help you make an informed buying decision.

First Generation (2010-2017):

  • Excessive Oil Consumption (2.4L Engine): This is a well-documented issue, particularly in the earlier model years. The piston rings are prone to wear, leading to oil leaking into the combustion chamber and burning off. Regularly checking the oil level is crucial. This issue led to a class action lawsuit.
  • Timing Chain Issues (2.4L Engine): Related to the oil consumption issue, low oil levels can accelerate wear on the timing chain, leading to potential engine damage. Listen for rattling noises on startup.
  • Water Pump Failure: Water pumps on the 2.4L engine are known to fail prematurely, potentially leading to overheating.
  • Airbag Issues: Certain models were affected by recalls related to Takata airbags. Ensure any Terrain you're considering has had the necessary airbag replacements performed.
  • Transmission Problems: Some owners have reported issues with the 6-speed automatic transmission, including hard shifting and slipping.

Second Generation (2018-Present):

  • 1.5L Turbo Engine Issues: Some owners have reported issues with the 1.5L turbocharged engine, including potential for engine stall or hesitation.
  • Electrical System Glitches: Reports of infotainment system freezes, sensor malfunctions, and other electrical glitches have surfaced.
  • Transmission Problems: While the 9-speed transmission is generally more refined, some owners have reported rough shifting or hesitation, particularly in the lower gears.
  • Turbocharger Problems: Potential for turbocharger failure in high-mileage models. Listen for unusual noises from the engine compartment.

Important Note: Thoroughly check the vehicle's history report (e.g., Carfax) for any reported accidents, maintenance records, and recall information. Have a qualified mechanic perform a pre-purchase inspection to identify any potential issues before buying.

Driving Experience

The GMC Terrain offers a comfortable and refined driving experience, although its performance characteristics differ depending on the generation and engine choice.

First Generation (2010-2017):

  • Pros: Comfortable ride, spacious interior, good cargo capacity, available all-wheel drive.
  • Cons: 2.4L engine can feel underpowered, particularly when fully loaded, 3.0L and 3.6L V6 engines offered better power but lower fuel efficiency. Boxy styling may not appeal to all buyers.
  • Overall: The first-generation Terrain is a decent choice for those prioritizing comfort and space, but the 2.4L engine's reliability issues should be a significant consideration.

Second Generation (2018-Present):

  • Pros: More modern and stylish design, improved fuel economy (especially with the 1.5L turbo), comfortable ride, available advanced safety features. The 2.0L turbo offers better performance.
  • Cons: Some may find the 1.5L engine lacking in power for passing or merging, especially when fully loaded. The 9-speed transmission can sometimes feel hesitant.
  • Overall: The second-generation Terrain is a more compelling choice, offering a better balance of style, technology, and fuel efficiency. The 2.0L turbo engine provides a more engaging driving experience.

Buying Advice

Here's some advice to help you find the best GMC Terrain for your needs:

Years to Look For:

  • 2013-2017 (First Generation): The mid-cycle refresh in 2013 addressed some of the earlier issues and offered updated styling. If considering the first generation, look for models with meticulous maintenance records, paying particular attention to oil change frequency and any evidence of oil consumption issues with the 2.4L. Avoid 2010-2012 models with the 2.4L engine due to increased oil consumption concerns.
  • 2018 and Newer (Second Generation): Offers the updated design, improved technology, and more efficient engine options. The 2.0L turbo offers the best performance.
  • 2022 and Newer (Second Generation - Facelifted): Offers updated styling and improved technology.

Years to Avoid (or be extra cautious about):

  • 2010-2012 (First Generation with 2.4L): High risk of excessive oil consumption issues.
  • Any model with a history of poor maintenance or significant accident damage.

General Recommendations:

  • Get a Pre-Purchase Inspection: This is essential, regardless of the year or generation. Have a qualified mechanic thoroughly inspect the vehicle, paying attention to potential engine, transmission, and electrical issues.
  • Check the Vehicle History Report: A Carfax or similar report will reveal any accidents, title issues, or reported maintenance records.
  • Test Drive Extensively: Pay attention to engine performance, transmission smoothness, and any unusual noises or vibrations.
  • Consider the Trim Level: Higher trim levels offer more features and amenities, but also come at a higher price. Determine which features are most important to you and choose accordingly. SLT and Denali trims offer the most luxury.
  • Factor in Maintenance Costs: Research the cost of common repairs and maintenance items for the Terrain model you're considering.

By carefully considering these factors, you can find a GMC Terrain that meets your needs and budget while minimizing the risk of potential problems.
