GMC Terrain Years to Avoid (Updated)

The GMC Terrain has been a strong contender in the compact SUV market since its debut in 2010. It combines a stylish design, advanced features, and a versatile driving experience. However, not all models of this popular SUV are created equal.

While some years deliver consistent reliability and satisfaction, others are plagued by issues that can lead to expensive repairs and frustration. If you’re considering a GMC Terrain, understanding which years are prone to problems is critical.

GMC Terrain Years to Avoid

When shopping for a GMC Terrain, some model years are more prone to issues than others. By identifying these problematic years, you can avoid unnecessary stress and financial burdens. Below, we highlight specific model years that are widely considered risky based on owner reports and expert reviews.

2010–2015

The GMC Terrain’s first generation, particularly models manufactured between 2010 and 2015, is infamous for reliability concerns. These vehicles are most commonly associated with excessive oil consumption, a problem that stems from design flaws in the engine’s piston rings. Many owners reported that their engines consumed oil at an alarming rate, often leading to engine damage if not addressed promptly.

Transmission troubles were also common in these years. Symptoms like hard shifting, delayed gear engagement, and, in some cases, total transmission failure were frequently reported. These issues often required expensive repairs or replacements, making these models less appealing for buyers seeking reliability.

2018

The 2018 GMC Terrain marked the start of the second generation, featuring a redesign with updated styling and technology. Unfortunately, this model year came with its own set of issues. Electrical system malfunctions were one of the most commonly reported problems, including glitches in the infotainment system and backup camera failures. Additionally, some owners experienced issues with the transmission, such as jerky gear shifts and hesitation during acceleration.

While newer models often show improvement, the 2018 GMC Terrain serves as a reminder that even a redesign doesn’t guarantee reliability. Potential buyers should approach this year with caution.

Common Issues in Certain GMC Terrain Model Years

The GMC Terrain has faced its share of challenges over the years. Certain models have been associated with recurring problems, which can make ownership stressful and costly. Understanding these issues is essential to making an informed decision about purchasing a used Terrain.

Excessive Oil Consumption

One of the most common complaints from GMC Terrain owners involves excessive oil consumption. This issue is particularly prevalent in models from 2010 to 2015. Owners often reported the need to add oil between scheduled changes, sometimes as frequently as every few weeks.

This problem stems from faulty piston rings, which allow oil to burn off faster than normal. Over time, excessive oil consumption can lead to engine damage, resulting in costly repairs or even complete engine failure.

Transmission Failures

Transmission issues are another area of concern for certain GMC Terrain models. Owners have reported symptoms such as delayed shifting, harsh gear changes, and, in some cases, complete transmission failure.

These problems are most commonly associated with early models and can require expensive repairs. The inconvenience and safety risks associated with transmission failures make this a critical factor to consider when evaluating older Terrains.

Electrical System Malfunctions

Electrical issues have also plagued some GMC Terrain models, particularly those released around 2018. Problems with infotainment systems, backup cameras, and other electronic components have been frequently reported.

These malfunctions can lead to an inconvenient ownership experience, affecting the overall enjoyment of the vehicle.

Frequently Asked Questions (F.A.Q)

Are all early GMC Terrain models problematic?

Not all early GMC Terrain models are inherently bad, but many from the 2010–2015 range have recurring issues. Excessive oil consumption and transmission failures were common complaints during these years. While some owners have had satisfactory experiences, these models often come with higher risks of costly repairs. If you’re considering one, ensure you have a trusted mechanic inspect the vehicle thoroughly.

How can I ensure a used GMC Terrain is reliable?

Start by obtaining a detailed vehicle history report to check for accidents, maintenance records, and recalls. A pre-purchase inspection by a qualified mechanic is also essential to identify potential problems. Test driving the vehicle can help you assess its performance, including engine smoothness, transmission shifting, and overall functionality. Look for any warning lights on the dashboard, as these may indicate underlying issues.

Are newer GMC Terrain models more reliable?

In general, newer GMC Terrain models have shown improvements in reliability and performance. Models from 2019 onwards are less likely to encounter the problems seen in earlier years. However, it’s still important to research individual years and reviews to ensure you’re making a sound investment. Even newer vehicles can have isolated issues, so don’t skip the due diligence process.

What’s the most common issue with the GMC Terrain?

The most widespread problem reported by owners is excessive oil consumption, particularly in models produced from 2010 to 2015. This issue, if not addressed, can lead to severe engine damage. Transmission failures and electrical malfunctions are other commonly reported concerns in various model years.

Should I avoid buying a used GMC Terrain altogether?

Not necessarily. The GMC Terrain offers many benefits, such as style, comfort, and features. By avoiding problematic model years and focusing on well-maintained vehicles, you can still enjoy this SUV. Researching and inspecting thoroughly will help you find a reliable option.

Wrapping Up

Purchasing a GMC Terrain can be a rewarding decision if you choose the right model year. While the SUV offers versatility, comfort, and style, it’s essential to be aware of the potential pitfalls associated with certain years. Early models from 2010 to 2015 are particularly notorious for issues like excessive oil consumption and transmission failures, which can lead to expensive repairs. The 2018 model also has a track record of electrical malfunctions and transmission concerns, making it another year to approach cautiously.
