2023 GMC Terrain Recall Details
2 recalls have been issued for the 2023 GMC Terrain. All recall repairs are performed free of charge at authorized dealerships.
CHILD SEAT
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."
Consequence
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.
Remedy
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.
AIR BAGS
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.
Consequence
In the event of a crash, a front passenger air bag that deploys with a child or infant in the front passenger seat can increase their risk of injury.
Remedy
Dealers will replace the passenger presence system, free of charge. Owner notification letters were mailed January 24, 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 N222388911.

FUEL/PROPULSION SYSTEM
3 complaintsOwners report several issues with the fuel/propulsion system of the 2023 GMC Terrain. Complaints frequently mention fuel pump failures, which lead to symptoms such as fuel spraying in the engine compartment, engine shutdowns, and significant loss of power. These issues have been noted at various mileages, with one report specifically citing a failure at 42,000 miles. Safety implications include the potential for the vehicle to shut down in traffic, requiring towing, and the risk of fire due to fuel leakage. This information is crucial for potential buyers considering a used GMC Terrain, as it highlights recurring issues that may affect reliability and safety.
UNKNOWN OR OTHER
2 complaintsOwners of the 2023 GMC Terrain report issues primarily involving engine and structural concerns. One complaint describes a complete engine failure at approximately 100,600 miles, including reduced engine power and a transmission module failure, limiting the vehicle's speed to 20 mph. Another owner reports a persistent rattling and shaking of the driver-side door at speeds over 65 mph, which they describe as concerning and unresolved despite service attempts. These issues highlight potential safety implications, particularly the engine failure affecting vehicle speed and the door's instability at highway speeds. Buyers should be aware of these reported problems, especially when considering vehicles with higher mileage or those used frequently on highways.
ENGINE (2 complaints)
ENGINE
2 complaintsOwners report issues with the 2023 GMC Terrain's engine, specifically involving the high-pressure fuel pump and rear main seal. Complaints frequently mention the vehicle unexpectedly entering limp mode, stalling, and hesitating to restart, which has occurred multiple times for some owners. Another owner describes a rear main seal leak that has left their vehicle at the dealership for an extended period without resolution, with the possibility of needing a new engine. These issues can occur at various mileage points, and the stalling and hesitating to start while driving may pose safety risks, particularly if they occur in traffic. Potential buyers should be aware of these reported problems and their implications for vehicle reliability and safety.
FUEL SYSTEM (2 complaints)
FUEL SYSTEM
2 complaintsOwners of the 2023 GMC Terrain report issues related to the fuel system that include stalling and loss of motive power. Symptoms frequently mentioned are the vehicle stalling at low speeds, shaking, and shifting into neutral unexpectedly, often accompanied by the illumination of the check engine light. One complaint notes a fuel module failure at approximately 12,825 miles, while another describes a possible fuel injector failure around 35,600 miles, with parts on backorder. These issues can lead to safety concerns, such as loss of control due to unexpected stalling or shifting, particularly at low speeds or while on trips. Potential buyers should be aware of these fuel system issues and the associated repair challenges when considering purchasing a used 2023 GMC Terrain.
LANE DEPARTURE (2 complaints)
LANE DEPARTURE
2 complaintsOwners of the 2023 GMC Terrain report issues related to lane departure and blind spot systems. One complaint describes a failure of the vehicle's sensors to detect obstacles at low speeds, resulting in a collision with an object, though no warning signals were activated. Another owner highlights the absence of the side blind zone alert feature due to a semiconductor shortage, which creates challenges in monitoring blind spots, especially in high-speed, dense traffic conditions. This absence is noted as particularly problematic given the vehicle's significant blind spots. Both complaints point to potential safety implications, such as increased risk of collisions due to lack of adequate warning systems. These issues are reported at low mileage and shortly after vehicle purchase, indicating early-stage concerns with these features.
STEERING (1 complaints)
STEERING
1 complaintSafety-relatedMy son was making a left onto a freeway on ramp after traffic cleared and the steering wheel completely locked up resulting in him going over the curb and rolling completely over in a steep ditch. This occurred at a low speed (no more than 25mph), confirmed by the Life369 app. My son's description was that it felt like the wheels were against a wall and the wheel wouldn't turn even though he was using both hands in an attempt to turn. My son said there was no warning lights or any other indication that he noticed, other than the complete locking up of the steering. The resulting rollover into the ditch has totaled the vehicle so it was not inspected by any collision shop. I attempted to check the steering in the tow yard but the vehicle had no power.

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent — Top-tier reliability, minimal issues
- 60–79: Good — Reliable with some minor concerns
- 40–59: Mixed — Notable issues, research before buying
- 0–39: Risky — Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
