Common problems reported by 2019 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.
