• Rod Bearing Failure: In more severe cases, engine knocking can be a sign of a failing rod bearing. This is a serious issue that can lead to catastrophic engine failure.

How to Fix Engine Knocking:

1. Use the Recommended Fuel: Always use the octane fuel recommended by Hyundai. Check your owner's manual. This simple fix can often resolve the problem immediately.
2. Fuel System Cleaning: Use a fuel system cleaner to remove carbon deposits. This can help to improve combustion efficiency.
3. Spark Plug Replacement: Have your spark plugs inspected and replaced if necessary. Make sure to use the correct type of spark plugs.
4. Professional Diagnosis: If the knocking persists, take your car to a mechanic for a proper diagnosis. It might be something more serious, like a rod bearing issue, which requires immediate attention.

Excessive Oil Consumption

Another common problem with the 2017 Hyundai Santa Fe 2.4L engine is excessive oil consumption. This means the engine is burning oil at a higher rate than it should. The signs include having to add oil frequently between oil changes, blue-gray smoke coming from the exhaust, and oil leaks. Excessive oil consumption can lead to engine damage if left unchecked. There are a few causes:

• Worn Piston Rings: Over time, piston rings can wear out, allowing oil to seep into the combustion chamber.
• Valve Seal Issues: Valve stem seals can harden and crack, leading to oil leakage.
• Internal Leaks: Problems within the engine's internal components can lead to oil leaks and consumption.

How to Fix Excessive Oil Consumption:

1. Regular Oil Checks: Check your oil level regularly (at least every other gas fill-up). Add oil as needed, using the recommended oil type.
2. Oil Consumption Test: Perform an oil consumption test to measure how much oil the engine is using over a specific mileage. This will give you a clearer picture of the issue.
3. Valve Seal Replacement: In some cases, replacing the valve stem seals can resolve the problem. This can be a labor-intensive repair, so get a quote from your mechanic.
4. Piston Ring Replacement: More serious cases may require a piston ring replacement. This is a more complex repair and can be costly.
5. Professional Diagnosis: Get a proper diagnosis by a trusted mechanic to pinpoint the exact cause of oil consumption and the best course of action.

Engine Stalling and Misfires

Engine stalling or misfires can be frustrating and can affect your vehicle's performance. When the engine stalls, it suddenly shuts down while running, while misfires cause the engine to run roughly or unevenly. Several things can cause these symptoms:

• Faulty Spark Plugs or Ignition Coils: As mentioned earlier, worn or malfunctioning spark plugs or ignition coils can disrupt the combustion process.
• Fuel System Issues: Clogged fuel injectors or a faulty fuel pump can disrupt fuel delivery, causing the engine to stall or misfire.
• Vacuum Leaks: Leaks in the vacuum system can also cause these symptoms.
