2015 Kia Forte

The 2015 Kia Forte is a compact sedan that offers a blend of affordability, fuel efficiency, and a decent array of features for its class. It was available with two engine options: a 1.8-liter four-cylinder producing 145 horsepower and 130 lb-ft of torque, and a more powerful 2.0-liter four-cylinder generating 173 horsepower and 154 lb-ft of torque. Both engines were typically paired with a 6-speed automatic transmission, though a 6-speed manual was available with the 1.8L. Owners generally appreciate the Forte’s value, comfortable ride, and user-friendly infotainment system. Common complaints revolve around its somewhat uninspired handling, potential engine issues, and occasionally troublesome electrical components.

Engine

1.8L Nu Engine

• Engine Knocking/Piston Slap
  • Description/Symptoms: Some owners report a noticeable knocking sound coming from the engine, particularly when cold or under load. This is sometimes described as piston slap. This can be a symptom of worn piston rings or cylinder walls.
  • Solution: A full engine rebuild or replacement may be necessary. A mechanic will need to properly diagnose this issue by checking compression and looking into the engine for damage.
  • Estimated Cost to Fix: $3,000 - $5,000+
• Excessive Oil Consumption

  • Estimated Cost to Fix: $500 - $5,000+
  • Recalls: None Found

Summary:

The 2015 Kia Forte, while offering value and features, does exhibit some common issues. Engine problems, particularly the knocking and potential failure in the 2.0L and oil consumption in the 1.8L, are of greatest concern due to their potential severity and high repair costs. Transmission issues, while less catastrophic, can still lead to significant expenses. Electrical gremlins and suspension component wear contribute to the overall ownership experience. The recalls, though important, don’t cover all potential engine issues. Potential buyers should be aware of these issues and carefully inspect any used 2015 Forte before purchase.
