Here’s a breakdown of common issues and complaints for the 2021 Kia Forte, focusing on different components and configurations. The 2021 Kia Forte is a compact car known for its value, fuel efficiency, and user-friendly technology. It’s generally praised for its spacious interior, comfortable ride, and long warranty. However, some common complaints include a somewhat uninspired driving experience and occasional issues with certain components. The Forte comes with a few different engine and transmission options. The most common is the 2.0-liter inline-4 cylinder engine producing 147 horsepower and 132 lb-ft of torque, paired with either a 6-speed manual transmission (on the FE trim) or an Intelligent Variable Transmission (IVT). A more powerful option is the 1.6-liter turbocharged inline-4, found in the GT trim, which delivers 201 horsepower and 195 lb-ft of torque, paired with either a 6-speed manual or a 7-speed dual-clutch transmission.

Engine

2.0L Inline-4 Cylinder

  • Engine Hesitation/Stalling
    • Description/Symptoms: Some owners report the engine hesitates or stalls, particularly at low speeds or when accelerating from a stop. This can be intermittent and difficult to diagnose.
    • Solution: This issue is often attributed to faulty Mass Airflow Sensor or dirty throttle body. Replacing the sensor or cleaning the throttle body often resolves the issue. Software updates to the ECU (Engine Control Unit) may also be necessary.
    • Estimated Cost to Fix: $100 - $300+
    • Recalls: None Found
  • Excessive Oil Consumption
    • Description/Symptoms: Some owners have reported excessive oil consumption, requiring them to add oil more frequently than expected between oil changes. The amount of oil consumption varies.
    • Solution: Monitoring oil levels regularly and addressing any leaks. If consumption is excessive, the dealer may perform an oil consumption test to determine the cause, which could lead to piston ring replacement or other engine repairs.
    • Estimated Cost to Fix: $500 - $3000+ (depending on the severity and required repairs)
    • Recalls: None Found

1.6L Turbocharged Inline-4 Cylinder

  • No Issues Found

Transmission

Intelligent Variable Transmission (IVT) [Paired with 2.0L Engine]

  • Shuddering/Jerking During Acceleration
    • Description/Symptoms: Some owners have reported a shuddering or jerking sensation, particularly during low-speed acceleration or when the transmission is “searching” for the correct gear ratio.
    • Solution: A software update to the Transmission Control Module (TCM) may resolve the issue. In some cases, a transmission fluid flush or replacement of the transmission may be required.
    • Estimated Cost to Fix: $100 - $500+ (depending on the solution)
    • Recalls: None Found

7-Speed Dual-Clutch Transmission [Paired with 1.6L Turbo Engine]

  • Hesitation or Jerky Shifting
    • Description/Symptoms: Owners have noted occasional hesitation or jerky shifting, especially at lower speeds. This can be more pronounced in stop-and-go traffic.
    • Solution: Some owners have found that resetting the transmission’s adaptive learning can improve shifting smoothness. In more severe cases, clutch replacement or TCM replacement may be necessary.
    • Estimated Cost to Fix: $100 - $2500+ (depending on the severity and required repairs)
    • Recalls: None Found

Suspension

  • Rear Suspension Noise
    • Description/Symptoms: Some owners have reported clunking or rattling noises coming from the rear suspension, particularly when going over bumps or uneven surfaces.
    • Solution: Inspect and replace worn or damaged suspension components, such as shocks, struts, or bushings. Tighten any loose bolts or fasteners.
    • Estimated Cost to Fix: $100 - $500+
    • Recalls: None Found

Electrical

  • Infotainment System Freezing/Crashing
    • Description/Symptoms: The infotainment system may freeze, crash, or become unresponsive. This can affect navigation, audio, and other functions.
    • Solution: Perform a system reset or software update if available. If the problem persists, the infotainment unit may need to be replaced.
    • Estimated Cost to Fix: $0 - $1000+ (depending on warranty coverage and repair needed)
    • Recalls: None Found
  • Backup Camera Malfunction
    • Description/Symptoms: The backup camera may fail to display an image or show a distorted view. This can be intermittent or permanent.
    • Solution: Check the camera connections and wiring for any damage or loose connections. Replace the camera if necessary.
    • Estimated Cost to Fix: $100 - $500+
    • Recalls: None Found

Exterior

  • No Issues Found

Interior

  • Driver’s Seat Squeaking
    • Description/Symptoms: Some owners have reported squeaking noises coming from the driver’s seat, particularly when shifting weight or during turns.
    • Solution: Lubricating the seat tracks and mechanisms. In some cases, the seat frame may need to be repaired or replaced.
    • Estimated Cost to Fix: $0 - $300+
    • Recalls: None Found

Summary

The 2021 Kia Forte generally offers good value and reliability, but some common issues have been reported. Engine hesitation and excessive oil consumption are potential concerns for the 2.0L engine. The IVT transmission can sometimes exhibit shuddering, and the 7-speed DCT can have jerky shifting. Electrical glitches, particularly with the infotainment system and backup camera, are also reported. Most of these issues range in severity from minor annoyances to potentially costly repairs, with repair costs potentially ranging from under $100 to upwards of several thousand dollars depending on the problem. Regular maintenance and prompt attention to any unusual symptoms are recommended to keep the vehicle running smoothly.
