What Problems Does the 2021 GMC Terrain Have?
The 2021 GMC Terrain, while generally reliable, has had some reported issues. Some owners have experienced issues with the 9-speed automatic transmission, including rough shifting or hesitation. There have also been reports of issues with the infotainment system, such as freezing or glitches. Some consumers have reported issues related to the fuel system. Specifically, there are reports of fuel pump failures. Earlier model years of the Terrain (2010-2017) had well-documented issues with excessive oil consumption, but this was largely addressed in later generations, including the 2021 model. Recalls have been issued for various reasons, including issues with the rearview camera display, improperly attached seat belts, and potential fuel leaks. It's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for the latest recall information related to your specific VIN. Long-term reliability concerns generally revolve around the potential for electronic issues and the longevity of the turbocharged engine. Regular maintenance and addressing any minor issues promptly can help mitigate these concerns. Always check for service bulletins related to these common problems. While the 2021 model is more reliable than earlier versions, potential buyers should still be aware of these potential problems and factor them into their decision-making process. Regular oil changes are highly recommended.
How long will the 2021 GMC Terrain last?
With proper maintenance, a 2021 GMC Terrain can reasonably be expected to last for 150,000-200,000 miles or 10-13 years. Long-term durability hinges on consistent oil changes, transmission servicing, and addressing any cooling system issues promptly. Weaknesses can emerge over time, particularly with the turbocharger, which may require replacement eventually. Electronic components, like the infotainment screen, can also experience failures as the vehicle ages. Preventative maintenance is key to maximizing its lifespan.

Stick to fresh tarmacRented it for two weeks in Hawaii. Drives and handles well as long as the tarmac is perfect. As soon as you hit ANY imperfections, bumps, cracks or potholes - or heaven forbid an unpaved road - it becomes an absolute disaster. Never seen anything as bad as this one. My stiffened Civic Si is more comfortable. An F.
