2025 GMC Terrain
Vehicle Specs & Maintenance Data
The 2025 GMC Terrain maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your GMC Terrain.
For oil changes, the 2025 GMC Terrain takes 0W-20 Full Synthetic motor oil with a capacity of 4.2 quarts. Brake fluid type is DOT 3, the recommended coolant is Dex-Cool (OAT), and transmission fluid is Dexron VI. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the GMC Terrain, torque the lug nuts to 100 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2025 GMC Terrain have reported 5 common issues including "1.5L Turbo Engine Excessive Oil Consumption", "Fuel Pump Module Failure" and "9-Speed Transmission Rough Shifting and Delayed Engagement".

Common problems reported by 2025 GMC Terrain owners, with recommended fixes and estimated repair costs.
1.5L Turbo Engine Excessive Oil Consumption
Like the Equinox, the GMC Terrain shares the 1.5L LYX turbocharged engine that suffers from excessive oil consumption. Owners report needing to add oil between scheduled changes, and some experience oil-related warning lights. Prolonged low oil conditions can damage the turbocharger and engine internals.
Use Dexos Gen 2 full synthetic oil and check oil levels regularly. Dealers may perform an oil consumption test. If consumption is excessive, piston ring or short block replacement may be covered under powertrain warranty. Use premium fuel as recommended per GM TSBs to reduce carbon buildup contributing to oil consumption.
Est. Cost: $0 (warranty) - $4,500 (engine rebuild out of warranty)Fuel Pump Module Failure
The fuel pump module can fail and deliver insufficient fuel to the engine, causing stalling and increasing crash risk. This is especially dangerous during highway driving or in traffic. The issue can develop gradually with intermittent symptoms before complete failure.
NHTSA Recall N222372310 covers the fuel pump module replacement. Dealers replace the defective module free of charge. Owners should watch for symptoms like rough idle, hesitation during acceleration, or intermittent stalling.
Est. Cost: $0 (recall repair)9-Speed Transmission Rough Shifting and Delayed Engagement
The 9-speed automatic transmission can exhibit rough shifting, hesitation during acceleration, jerking at low speeds, and delayed gear engagement. Some owners report the transmission slipping or the vehicle lurching forward unexpectedly. These issues are most noticeable during city driving with frequent stop-and-go conditions.
Transmission adaptive learning reset and software update at the dealer. Transmission fluid drain and fill with updated fluid specification. In cases of internal damage, torque converter or complete transmission replacement may be necessary.
Est. Cost: $0 (software update) - $4,000 (transmission replacement)Crank Seal Failure and Oil Leak
Some owners report the front crankshaft seal blowing out, leading to significant oil leaks onto the engine and ground. If not caught quickly, the rapid oil loss can cause engine damage. Owners may notice oil spots under the vehicle, burning oil smell, or smoke from the engine compartment.
Replace the front crankshaft seal and inspect the crankcase ventilation system for excessive pressure that may have caused the seal failure. Clean engine of residual oil. Some cases require replacement of the crankshaft position sensor if oil damage occurred.
Est. Cost: $400 - $1,200Defective Hankook Tires (Tread Separation)
Certain 2022 Terrain vehicles equipped with Hankook tires were manufactured with an insufficient amount of curative agent during the tire vulcanization process. This defect can cause tread separation while driving, resulting in a loss of vehicle control and a blowout at highway speeds.
NHTSA recall issued for affected Hankook tires. Dealers inspect and replace defective tires free of charge. Owners should check for bulges, uneven tread wear, or vibrations that may indicate tread separation beginning.
Est. Cost: $0 (recall repair)
