2021 GMC Terrain

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.

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.

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.

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.

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.

General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."

The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.

Owners are advised to install child seats using the vehicle's rear seat belts until the remedy is complete. Dealers will inspect the latch anchorage bars, and remove and replace the finish, as necessary, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232403240.
