Some owners also mention problems with the gas door not opening, while one describes a window shattering unexpectedly. These issues typically appear early in the vehicle's use, with some owners experiencing them within a few months.

SEAT BELTS (2 complaints)
SEAT BELTS
2 complaintsOwners report issues with the seat belts in the 2023 Kia Carnival, specifically in the rear middle and second-row seats.

One owner describes their child being unsecured as a result. The issues are noted at approximately 30,000 miles, with parts on backorder and no immediate resolution from dealerships or the manufacturer. These malfunctions have potential safety implications, as the seat belts may not secure passengers effectively in the event of a sudden stop.
ENGINE (2 complaints)
ENGINE
2 complaintsOwners report two main issues with the 2023 KIA Carnival's engine. The first involves a persistent strong fuel smell, with one owner noting that a dealership attempted to address it by replacing fuel injection parts after identifying a leak, but the issue persists. The second issue described involves an engine warning where, after driving for an hour and idling for 30 minutes with a low fuel level, the vehicle prompted the driver to restart the engine. No specific mileage ranges are mentioned, and there are no reports of crashes, fires, or loss of control linked to these issues. These complaints suggest potential concerns with the fuel system and engine management, which prospective buyers might want to investigate further.

STEERING
2 complaintsOwners of the 2023 Kia Carnival report issues with fluid leaks from the steering column, with one case describing an unknown fluid leaking while driving, and another noting oil leaking onto the floorboard near the brake pedal.

The reported issues occur at mileage as low as 3,337 and around 10,000 miles. Safety implications are suggested by the potential for steering wheel seizure, but no crashes or injuries are reported.

Look Up a VIN →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.
