FUEL SYSTEM (2 complaints)

FUEL SYSTEM

2 complaints

Owners of the 2024 Kia K5 report issues related to a recall concerning the fuel system, specifically NHTSA Campaign Number: 25V794000. The primary concern is the unavailability of parts necessary for the recall repair, which has led to delays in addressing potential safety risks. Although no actual failures, such as fires or other incidents, have been reported by the owners, the delay has impacted some owners' plans, such as vehicle shipping. These complaints do not specify mileage ranges, but they highlight frustration with the manufacturer's timeline for providing a resolution.

On 10/20/25 as a rideshare driver one of my riders told me that the right side back seat was lifting. I could not believe what the rider was telling me until one of my family members told me the same thing. I immediately for safety reasons parked the car and started searching about any problems with the gas tank, for my surprise there was a serious safety problem in the car where the gas tank was expanding. The car could have got on fire and exploited putting my family, riders and myself at the risk of death. This was reported to Kia Customer Care on 10/20/2025, case # XXX, and later was complemented with the Kia Customer Care case # XXX. On 11/11/25 Kia America recognized that the car was unrepairable and offered a buyback process which was accepted by me on 11/12/25. It has passed 105 days since the car was parked and not used for ridesharing, my main source of income. During this 105 days Kia Finance America has been demanding payments from me, they have not stopped the billing despite my several request. Kia offered me rent a car through Enterprise which does not allow to do ridesharing with their cars, and also car rental reimbursement which I cannot afford. As of today, my lost income has achieved the amount of $ 33,036.77; this was warned to Kia America since the beginning of the process. Kia America has been very a bureaucratic company, and the buyback process has not been finished due to the lack of check from Kia America to the company Morley. All I want is to finish the buyback process because it is giving me a very bad psychological and economic hardship times.

The contact owned a 2024 Kia K5. The contact stated that while his son was driving at an undisclosed speed, another vehicle abruptly crossed into his lane. As a result, the contact's son collided with the rear of the other vehicle. Although equipped, the forward warning collision and automatic emergency braking systems failed to activate, which could have possibly prevented and/or lessened the severity of the collision. The air bags did deploy. No warning lights were illuminated. A police report was filed, and injuries were reported. The contact's son was transported to an area hospital by EMT and treated for a broken wrist. The vehicle was towed to a tow yard and deemed a total loss. The manufacturer was not notified of the failure. The failure mileage was 1,400.

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

1

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.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

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.

4

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.
