Getting the Most Out of Every Mile Ahead: Your GMC Terrain Maintenance Schedule

The GMC Terrain is a steadily growing star in the SUV industry, renowned for its adaptable performance, sporty aesthetic, and premium interior. The Terrain showcases what GMC does best––balancing luxury and capability with versatility and functionality. If you own a Terrain or are interested in finding one, you might already know this and are likely looking for ways to get the most from your Terrain every mile ahead. One of the most surefire ways to get longevity out of any new or used vehicle is keeping up with a routine maintenance schedule. As your dedicated GMC service center, we’re here to help.

Why Is Routine Maintenance Essential?

Your Terrain is an investment; as a vehicle owner, you’re responsible for protecting and maintaining that investment. Otherwise, it’s a waste of money and time because your vehicle won’t have everything it needs to run efficiently or effectively. As a result, you’ll spend more money on complex repairs or, in worst-case scenarios, lose money when you get less for your trade than it’s worth.

Following a maintenance schedule is the best way to avoid this loss, protect your investment, and get the most from your Terrain. GMC outlines the ideal maintenance schedule for your vehicle in the owner’s manual. Yet, you don’t have to thumb through a book or navigate the digital copy on your Terrain’s center touchscreen. Instead, we’re here to make life and vehicle maintenance easier.

Maintenance Every 7,500 Miles: Covering the Basics

The engine that powers your GMC Terrain relies on many moving components, which generate a lot of heat or friction. The engine’s position under the hood also makes it susceptible to picking up dirt and debris, which can cause damage or lead to corrosion. Fortunately, oil mitigates these issues by lubricating, cleaning, and cooling the engine while you drive. Eventually, everyday wear and tear reduces the oil level, while dirt and debris can turn it into sludge and make it less effective.

GMC recommends checking your Terrain’s oil level and life percentage every 7,500 miles and, if need be, changing the oil and filter out. If you bring your Terrain to us for this service, our technicians will also rotate the tires, replace the air filter, and conduct a multi-point vehicle inspection, all other tasks that GMC recommends doing every 7,500 miles. Rotating the tires promotes even tread wear and extends their longevity, helping you get more from the tires before replacing them. Finally, a multi-point inspection gives you a thorough report on your Terrain’s current condition and helps you plan for future repairs and needs like tires. How so?

During the multi-point vehicle inspection, our technicians will assess your vehicle’s major components, from its technologies to the brakes, transmission, and engine. For example, our technicians will run diagnostics to look for recalls and check the service history. They’ll check the engine oil level and reset the oil life monitoring system. From there, they’ll test the battery, inspect the cables and connections, and evaluate the transmission, transfer case, cooling system, tires, and brakes. The cabin is also inspected, from the floormats and door locks to the horn, radio, and sound system.

Maintenance Every 22,500 Miles: Covering the Basics + the Air Filter

Your Terrain’s maintenance schedule is progressive, but what does that mean? Every 7,500 miles requires an oil change, tire rotation, and multi-point inspection. So, at 15,000 miles, you’ll bring your Terrain in for its second round of services–an oil change, tire rotation, and multi-point inspection. When you’ve logged around 22,500 miles, our technicians will follow GMC’s guidelines and replace the passenger compartment air filter.

The air filter prevents environmental allergens from getting into the cabin. Over time, however, the filter accumulates dust and debris, eventually losing effectiveness. This accumulation occurs faster and requires more frequent filter replacement if you spend a lot of time driving in areas with heavy traffic, high dust levels, and poor air quality.

Maintenance Every 45,000 Miles: The Basics + Transmission Fluid

When you bring your Terrain in for its 45,000-mile service, you can expect another item to be added to our list of musts. Like every other routine service appointment, our technicians will change the oil, rotate the tires, conduct a multi-point inspection, and address any areas of concern. With 45,000 miles, they’ll also change the automatic transmission fluid, but why is this service essential for your Terrain?

Just as oil lubricates the engine’s many moving components, the transmission fluid keeps your transmission lubricated and cooled. With the Terrain’s automatic transmission, the transmission fluid also provides the hydraulic pressure necessary for the transmission to shift gears. Changing the transmission fluid is essential to the transmission’s longevity and performance, with more frequent changes required if you spend more time driving in stop-and-go traffic, as frequent braking and accelerating can cause added wear and tear.

Maintenance Every 60,000 Miles: The Basics + Spark Plugs

By the time your Terrain reaches 60,000 miles, you’ve likely enjoyed driving the SUV for approximately five years. This means it’s time for a few more extensive services, like checking the evaporative cooling system, inspecting the tires and replacing them if necessary, and checking the brake system. For some drivers, it might be time for a complete brake service, where our technicians will replace the brake pads, rotors, and brake fluid.

Beyond covering the basics, our technicians will inspect and replace your Terrain’s battery if it hasn’t already been done. This would also be the time to replace the spark plugs, inspect the wires or boots, and replace the coolant. This comprehensive service sets your GMC up for its next 7,500-mile stretch and continues the maintenance schedule trend.

Maintenance Every 75,000 Miles: The Basics + AWD-Specific Services

Your 75,000-mile maintenance appointment will look slightly different if you drive an all-wheel drive (AWD) Terrain. At this interval, GMC recommends changing the rear axle or differential fluid, and our technicians will replace the contaminated fluid with GMC’s recommended OEM fluid during this service. Why is this service essential?

An AWD vehicle like the Terrain has a gearbox, also known as the differential. The differential is home to various gears that optimize traction as the wheels on your Terrain rotate. The movement of the gears generates friction, making the differential oil or rear axle fluid essential to lubricating the gears and mitigating heat. Replacing the differential fluid ensures your AWD Terrain has the proper lubrication as you confidently navigate slippery conditions.

With this service checked off your list, Terrain owners should also plan to have the air conditioner serviced. GMC recommends servicing the air conditioner every seven years, so you’ll likely want to schedule this around the 75,000-mile service. During this process, we’ll inspect the system and replace the air conditioning desiccant, ensuring your air condition runs its best and continues to do so for the next seven years.

Maintenance Every 150,000 Miles: The Ten-Year Service

The Terrain’s ten-year service is a momentous occasion because it means you have a front-row seat to GMC’s stellar reputation for building long-lasting and reliable vehicles. During this ten-year service, which occurs after 100,000 miles, we’ll cover the basics and thoroughly assess the SUV, as a lot can happen to a vehicle over ten years. For example, we’ll inspect the hoses and belts and flush and replace the power steering fluid at your 90,000-mile service. Then, at the 100,00-mile service, we’ll replace the struts and cover the basics–an oil change, tire rotation, and multi-point inspections. At the 150,000-mile service, we’ll change the rear axle fluid if your Terrain is AWD. We’ll also inspect, drain, and fill the engine cooling system to ensure your engine has everything it needs to run efficiently without the risk of overheating.
