2023 Hyundai Sonata
The 2023 Hyundai Sonata is a mid-size sedan known for its stylish design, comfortable ride, and impressive technology features. It’s offered with several engine options: a 2.5L GDI 4-cylinder engine (191 hp and 181 lb-ft of torque), a 1.6L Turbo-GDI 4-cylinder engine (180 hp and 195 lb-ft of torque), and a 2.0L GDI 4-cylinder hybrid engine (192 hp combined). A major draw to the Sonata is its user-friendly infotainment system and overall value. Some common criticisms include slightly uninspired handling compared to rivals and the polarizing design elements for some.
Engine
2.5L GDI 4-Cylinder Engine
- Excessive Oil Consumption
- Description/Symptoms: Some owners have reported higher-than-expected oil consumption, requiring more frequent oil top-offs between scheduled oil changes. The engine may also exhibit a burning oil smell.
- Solution: Initially, monitoring oil consumption to establish a baseline is recommended. If consumption exceeds manufacturer specifications, potential solutions include replacing valve stem seals, piston rings, or in severe cases, the entire engine.
- Estimated Cost to Fix: $500 - $5,000+ (depending on the severity and repair needed)
- Recalls: None Found
- Engine Knocking/Ticking Noise
- Description/Symptoms: Owners report hearing a knocking or ticking noise coming from the engine, especially during cold starts or acceleration. This can sometimes indicate a potential issue with the connecting rod bearings or valvetrain components.
- Solution: Diagnosis involves checking engine oil pressure, inspecting the valvetrain, and potentially disassembling the engine to examine the connecting rod bearings. Repair may involve replacing the affected components.
- Estimated Cost to Fix: $500 - $4,000+ (depending on the source and extent of the damage)
- Recalls: None Found
1.6L Turbo-GDI 4-Cylinder Engine
- Hesitation/Stuttering During Acceleration
- Description/Symptoms: Some owners report experiencing hesitation or stuttering, particularly during initial acceleration or when attempting to pass. This could be related to fuel delivery, turbocharger operation, or ignition system issues.
- Solution: The issue needs a diagnostic review, and it could require replacing the boost pressure sensor.
- Estimated Cost to Fix: $200 - $1,000+ (depending on the cause)
- Recalls: None Found

- Recalls: None Found
- Malfunctioning Sensors/Warning Lights
- Description/Symptoms: Erroneous warning lights on the dashboard, such as TPMS (Tire Pressure Monitoring System), ABS (Anti-lock Braking System), or Check Engine Light. The cause can be due to faulty sensors that need replacing.
- Solution: Replacing the faulty sensor or addressing the underlying issue triggering the warning light.
- Estimated Cost to Fix: $100 - $500+ (depending on the sensor type and location)
