STRUCTURE:BODY:DOOR
General Motors, LLC (GM) is recalling certain 2024 Chevrolet Blazer, Blazer EV, Equinox, and GMC Terrain vehicles. The door strikers may fracture, resulting in the door opening unexpectedly.
AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:FRONT PASSENGER
General Motors, LLC (GM) is recalling certain 2023 Chevrolet Equinox and GMC Terrain vehicles equipped with ventilated front passenger seats. The Occupant Classification System may not properly disable the front passenger air bag when there is a small child or child restraint detected in the seat.
CHILD SEAT:VEHICLE LATCH ANCHOR
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."
SEATS
General Motors, LLC (GM) is recalling certain 2022-2023 Chevrolet Equinox and 2022 GMC Terrain vehicles. The driver's seat may have a stripped or loose bolt at the seat frame height-adjust pivot.
TIRES
General Motors, LLC (GM) is recalling certain 2021-2022 Chevrolet Equinox and GMC Terrain vehicles equipped with certain Hankook tires. The tires may have been manufactured with an insufficient amount of curative agent, which could cause tread separation.

Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The 2.4L LEA and LE9 four-cylinder engines in 2010-2017 Terrain are among the most reported excessive oil consumption issues in GM's lineup. Many owners consume 1 quart of oil every 1,000-2,000 miles. The root cause is inadequate piston ring tension combined with piston ring land… Repairs typically run $1,200-$6,500. Severity: high.
First-generation Terrains (shared with the Chevy Equinox) develop a "sticky" power-steering condition where the wheel binds on-center - most often after long straight-highway driving - and requires noticeably higher effort to turn. NHTSA investigated roughly 781,000 2010-2012 uni… Repairs typically run $600-$1,500. Severity: high.
The GM Ecotec 2.4L in the 2010-2014 Terrain has the same timing chain stretch and tensioner failure as the Equinox and Malibu. GM Special Coverage Adjustment SCA 12313C covers some vehicles. The 2010-2011 models are worst affected. Improperly hardened piston rings on 2010-2013 mo… Repairs typically run $1,000-$3,000. Severity: high.
First-generation Terrains ordered with the optional V6 - the 3.0L LF1 in 2010-2012 and the 3.6L LFX from 2013-2017 - use GM's High Feature V6 architecture with four timing chains. The chains and their tensioners/guides stretch and wear prematurely, particularly on engines run on… Repairs typically run $1,800-$4,000. Severity: high.
The 2010-2017 Terrain uses the GM 6T40 (2.4L) and 6T45 (V6) 6-speed automatic transmissions, both of which suffer from torque converter shudder, harsh shifts, and solenoid failures. The shudder occurs at light throttle between 30-50 mph when the torque converter clutch locks up. Repairs typically run $150-$2,800. Severity: medium.
The engine-driven water pump develops bearing/impeller wear or seal leaks, allowing coolant to weep (often visible as dried Dex-Cool on the timing-chain cover or flung from the pump pulley) and eventually causing overheating. On both the 2.4L Ecotec and 3.6L V6, the pump is timin… Repairs typically run $1,008-$1,443. Severity: medium.
Terrain front and rear hub assemblies integrate the ABS magnetic encoder ring into the bearing's inboard seal, where it sits directly exposed to road salt and moisture. Two distinct failure modes result. The mechanical one is the familiar humming or roaring that rises with speed… Repairs typically run $300-$800. Severity: medium.
First-generation Terrains (2010-2017) are prone to a sudden 'Reduced Engine Power' warning caused by a failing electronic throttle body. Carbon and grime build up inside the bore and the internal throttle position sensor (TPS) fails or reads erratically, causing the ECM to enter… Repairs typically run $250-$650. Severity: medium.
GM recalled 740,581 first-generation Terrains because an internal reflection in the headlamp housing throws excessively bright light above the beam pattern and outside the driver's own field of view. The vehicles do not comply with Federal Motor Vehicle Safety Standard 108. The s… Repairs typically run $0-$0. Severity: medium.
Sunroof-equipped first-generation Terrains use a drain trough around the glass panel with four hoses routed down the A-pillars and out through the rear body-side extensions. The original-design hoses are small in diameter and prone to clogging with debris and factory sealant resi… Repairs typically run $100-$800. Severity: medium.
The HVAC blend/mode-door actuators fail as their internal plastic gears strip, producing a repetitive clicking or knocking sound from behind the dash and causing loss of temperature or airflow control. On dual-zone systems one side commonly blows hot while the other blows cold, o… Repairs typically run $150-$450. Severity: low.
The fuel level sensor in the in-tank pump module is a potentiometer whose wiper rides on a resistor card. Sulfur compounds in pump gasoline plate onto the card, and varnish builds on the float arm pivot, so the sender's resistance no longer tracks actual tank level. First-generat… Repairs typically run $350-$900. Severity: low.
