- The Symptoms: The most telltale sign is a distinct knocking noise coming from the engine. It often starts as a faint tick and grows louder as you accelerate. In many cases, the engine warning light may not appear until the damage is already severe.
- The Cause: Investigations suggest that improper machining or debris left in the oil galleries during the manufacturing process can restrict oil flow to the bearings. This leads to premature wear and, eventually, the rod snapping.
- The Result: This often results in the engine seizing or "throwing a rod," which totals the engine block.
- The Fix: If the knock is present, the engine usually requires a complete replacement or a rebuild. Note: Hyundai has issued extended warranties and service campaigns for this specific issue in many markets, so check with your local dealer immediately if you hear a knock.
- Thermostat housing cracks (coolant loss).
- Water pump bearing failure (whining noise).
