The GMC Terrain has built a loyal following since its debut in 2010. The 2018–2024 generation continues that reputation with refined styling, advanced safety features, and efficient turbocharged engines.
Even dependable vehicles have their challenges. Many owners have raised concerns about the 2024 GMC Terrain's issues, which can impact day-to-day driving comfort and long-term reliability. Understanding what these problems mean and how to address them helps you stay in control of performance.
As the compact SUV market becomes increasingly competitive, the Terrain remains popular among drivers who value space, technology, and all-weather capability. However, like its earlier models, the 2024 version carries a few familiar pain points that every owner should know.
Common Problems with the 2024 GMC Terrain
Engine and Emission Performance Issues
The most common problems with the 2024 GMC Terrain relate to the powertrain and emission systems. The turbocharged 1.5-liter four-cylinder engine delivers solid efficiency but has been linked to occasional power loss, misfires, and carbon buildup on intake valves.
These issues often arise after prolonged city driving or inconsistent oil maintenance, resulting in reduced throttle response and lower fuel economy. Drivers who experienced similar issues in earlier model years (particularly those from 2018 to 2020) often describe rough idling and delayed acceleration when starting the vehicle from cold.
Transmission Concerns and Drivability
Transmission performance also continues to generate discussion among GMC Terrain owners. The nine-speed automatic transmission offers smoother ratios than the previous six-speed. However, some drivers still notice complex or delayed gear changes.
Software calibration can sometimes cause hesitation during quick throttle inputs, which becomes more noticeable in stop-and-go traffic. Keeping transmission fluid clean and at the proper level helps prevent premature wear, especially for commuters traversing busy urban routes or steep grades.
Electrical and Infotainment System Problems
The electrical systems in newer GMC Terrain models have become increasingly sophisticated, bringing both convenience and complexity. Some owners report intermittent infotainment issues such as frozen touchscreens, dropped Bluetooth connections, or unresponsive navigation.
While these glitches rarely affect drivability, they can disrupt daily commutes that depend on consistent connectivity. Updated firmware or system resets usually resolve these frustrations.
How GMC Terrain 2024 Problems Affect Everyday Driving
Even minor issues can influence daily commuting. A small transmission hesitation or a flickering warning light might not immobilize the vehicle, but can turn a regular drive into a persistent distraction. The check engine light often signals manageable problems, such as a loose gas cap, a worn oxygen sensor, or a clogged catalytic converter. Ignoring these warnings, however, may lead to costly repairs.
Drivers also mention that turbocharged engines are sensitive to oil quality and frequency of changes. Skipping intervals or using the wrong viscosity can lead to overheating, loss of lubrication, or early turbo wear. Combined with stop-and-go traffic and short trips, this can stress both engine and transmission components.
Ride quality can also degrade when suspension components wear prematurely, especially on models driven in regions with harsh winters or rough roads. Worn struts and shocks lead to body roll and uneven tire wear, reducing both comfort and safety. These issues may not appear overnight, but attentive inspection helps spot them early.
Addressing Problems with The 2024 GMC Terrain
Regular maintenance remains the strongest defense against performance decline. Replacing spark plugs and air filters, cleaning the mass airflow sensor, and checking for software updates all contribute to keeping the Terrain’s systems running at peak condition. Using quality fuel and keeping tires properly inflated can also improve fuel economy and drivability over time.
