Engine
2.5L GDI 4-Cylinder Engine
- Excessive Oil Consumption
- Description/Symptoms: Some owners report higher than expected oil consumption, requiring more frequent oil additions between scheduled changes. Symptoms may include low oil level warnings, blue smoke from the exhaust, and a burning oil smell.
- Solution: Hyundai is currently investigating reports. The recommended solution currently involves closely monitoring oil levels and performing oil consumption tests at the dealership to establish a baseline. If consumption exceeds acceptable levels, engine repairs or replacement may be necessary.
- Estimated Cost to Fix: Varies, $0 (for oil consumption test under warranty) to $3,000+ (for engine replacement out of warranty).
- Recalls: None Found
1.6L Turbo-GDI 4-Cylinder Engine
- Engine Hesitation/Stalling
- Description/Symptoms: Some owners have reported hesitation upon acceleration or intermittent stalling, particularly in colder weather. The issue may be related to fuel delivery or sensor malfunctions.

Summary
The 2024 Hyundai Sonata appears to have a mix of minor and potentially more significant issues. The most common complaints revolve around the engine (oil consumption, hesitation) and transmission (rough shifting), which, if unaddressed, could lead to more costly repairs down the line. Electrical issues, particularly with the infotainment system and sensors, also appear to be prevalent. While some issues are relatively inexpensive to fix, others like engine replacements can be substantial. The severity and cost of these issues depend greatly on whether the vehicle is still under warranty. Potential buyers should carefully inspect the vehicle and consider having a pre-purchase inspection performed by a trusted mechanic.
