As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Controls and Displays" and 138, "Tire Pressure Monitoring System."

Consequence

An instrument panel display that fails to show critical safety information, such as the speedometer, tire pressure, or warning lights, increases the risk of a crash.

Remedy

The instrument panel display software will be updated over-the-air (OTA) or by a dealer, free of charge. Owner notification letters are expected to be mailed March 26, 2026. Owners may contact Kia Customer Service at 1-800-333-4542. Kia's number for this recall is SC361. Vehicle Identification Numbers (VINs) involved in this recall will become searchable on NHTSA.gov on February 9, 2026.

2026 KIA Carnival Common Problems by Component

13 owner complaints grouped by vehicle system.

POWER TRAIN (5)VEHICLE SPEED CONTROL (3)ELECTRICAL SYSTEM (2)UNKNOWN OR OTHER (2)BACK OVER PREVENTION (1)

POWER TRAIN

5 complaints

Owners report several power train issues with the 2026 KIA Carnival, primarily involving sudden loss of power and acceleration problems. Complaints frequently mention the vehicle entering a "limp mode," limiting speed to around 31 mph, and in some cases, complete power loss occurs without warning. These issues typically arise in vehicles with low mileage, often under 1,500 miles. Safety implications are significant, as multiple owners describe situations where the vehicle's inability to maintain speed or accelerate nearly led to accidents, particularly at highway speeds. Additionally, some reports indicate engine warning lights and diagnostic codes appearing after these incidents, suggesting potential underlying mechanical or electronic faults.

5 complaints total

VEHICLE SPEED CONTROL

3 complaints

Owners report that the 2026 KIA Carnival experiences issues with vehicle speed control, particularly in cold weather conditions. Complaints frequently mention the vehicle's inability to accelerate past 31 mph regardless of the gas pedal position, with this issue occurring during temperatures below 35F. Another reported problem involves a malfunctioning speedometer that inaccurately displays speed, sometimes showing zero while the vehicle is moving. These issues appear to temporarily resolve after restarting the vehicle. Additionally, one owner describes a broader system failure affecting multiple vehicle functions, including the speedometer, which has resulted in extended repair shop visits. These symptoms suggest potential safety concerns regarding accurate speed monitoring and vehicle control.

3 complaints total

ELECTRICAL SYSTEM

2 complaints

Owners report that the 2026 KIA Carnival experiences significant electrical system issues shortly after purchase. Complaints frequently mention problems such as the instrument display panel failing to turn on, electrical shorts affecting the radio, and the vehicle's battery dying, which can render the car inoperable. These issues typically occur within the first few weeks of ownership. Safety implications are noted, as the instrument display panel failure disables critical features like the rearview camera and camera monitoring system. Prospective buyers should be aware that these electrical issues can lead to extended repair times and unresolved diagnostic outcomes, as evidenced by one vehicle being out of service for 15 days without a clear resolution.

2 complaints total

UNKNOWN OR OTHER (2 complaints)

UNKNOWN OR OTHER

2 complaints

Owners of the 2026 KIA Carnival report issues primarily related to vehicle speed limitations and driver assistance warnings. One complaint describes an inability to exceed 31 mph, particularly in cold weather conditions, with the issue occurring at just under 3,000 miles. Another complaint highlights frequent and distracting "COFFEE BREAK" warnings from the driver assistance system, which cannot be disabled and occur every 10 minutes, regardless of driver status. These issues suggest potential safety implications, especially concerning the speed limitation problem occurring on highways. Buyers should be aware of these reported concerns, particularly in cold climates or when relying on driver assistance features.

BACK OVER PREVENTION (1 complaints)

BACK OVER PREVENTION

1 complaint

2025-12-22

I am submitting a safety complaint regarding unexpected and inappropriate automatic braking behavior at low speeds involving the parking sensors, rear cross-traffic alert, and/or automatic emergency braking system. While performing normal, low-speed maneuvers such as backing out of street parking spaces or parking in tight urban environments, the vehicle abruptly applies the brakes even when no imminent collision exists and when obstacles or traffic are clearly visible to the driver. In one frequent scenario, while exiting a parallel out of a parking spot into traffic, the vehicle suddenly stops itself while partially in the roadway due to a car approaching in the rear. This occurs despite sufficient clearance and approaching vehicles slowing to yield or even happens AFTER the approaching vehicle has passed already! This creates a dangerous situation where my vehicle is immobilized in active traffic, increasing the risk of rear-end or side collisions. The driver behind me sees me stopped in middle thinks that I'm waiting for him, when really my intention was to come out of the spot and then finally it releases the emergency brake and then my vehicle juts out into the roadway. Also, during parking maneuvers, the vehicle applies emergency braking despite having enough space, SLOW speed, & the driver having full visual awareness via the backup camera. This removes the driver’s ability to make precise low-speed adjustments. The override behavior is also unsafe. Regaining control requires a firm brake press, after which releasing the pedal causes the vehicle to move abruptly, eliminating precise control and increasing collision risk. This behavior is unpredictable, inappropriate for dense urban driving, & creates hazardous situations rather than preventing them. I believe this constitutes a safety defect in the vehicle’s braking and driver-assist systems. Concerned this could lead to serious accidents, particularly in urban environments. Friends have same problems!

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.
