2019 Kia Optima

The 2019 Kia Optima is a mid-size sedan known for its value, spacious interior, and comfortable ride. It’s available with three engine options: a 2.4L inline-4 (185 hp, 178 lb-ft of torque), a 1.6L turbocharged inline-4 (178 hp, 195 lb-ft of torque), and a 2.0L turbocharged inline-4 (245 hp, 260 lb-ft of torque). The 2.4L and 2.0L engines are paired with a 6-speed automatic transmission, while the 1.6L is mated to a 7-speed dual-clutch transmission. Owners generally appreciate the Optima’s styling, features for the price, and fuel economy. Common dislikes include occasionally unrefined engine performance, particularly with the base 2.4L engine and some reports of transmission issues.

Engine

2.4L Inline-4

• Engine Stalling
  • Description/Symptoms: The engine may stall unexpectedly while driving, especially at low speeds or when idling. This can be intermittent and may or may not be accompanied by a check engine light.
  • Solution: Diagnosing the cause of stalling can be complex and might involve checking the fuel system, ignition system, or sensors. Some owners have reported that replacing the mass airflow sensor or throttle position sensor resolves the issue. Others have needed software updates to the ECU.
  • Estimated Cost to Fix: $100 - $500+
  • Recalls: None Found
• Oil Consumption
  • Description/Symptoms: Excessive oil consumption, leading to low oil levels between oil changes. This can cause engine damage if not monitored and addressed. Symptoms include the need to add oil frequently and potential engine knocking noises.
  • Solution: In some cases, a software update to adjust oil consumption parameters has been implemented. If the problem persists, engine repairs or replacement may be necessary.
  • Estimated Cost to Fix: $0 (software update) - $3,000+ (engine repair/replacement)
  • Recalls: None Found
