Common Issues with the 2016 Kia Sedona Engine

While many 2016 Sedonas run for well over 150,000 miles with regular maintenance, some owners have reported issues that you should be aware of—especially if you’re in the market for a used one or considering an engine replacement.

1. Carbon Buildup (GDI engines)

Because the 2016 Kia Sedona uses a Gasoline Direct Injection system, carbon deposits can build up on the intake valves over time, leading to rough idle or reduced fuel efficiency.

Solution: Walnut blasting every 60,000–80,000 miles or using a catch can.

2. Timing Chain Wear

Though less common than in older timing belt engines, timing chain tensioners in some Sedonas can stretch or fail, leading to rattling noises and poor performance.

Solution: Early detection and replacement prevent further damage.

3. Oil Leaks

Some owners have noted minor oil leaks around the valve cover gasket and oil pan after 100,000 miles.

Solution: Regular inspection and affordable gasket replacements can prevent more serious issues.

Signs You May Need a Replacement Engine

If your 2016 Sedona is showing these symptoms, it might be time to consider an engine replacement:

• Knocking or tapping sounds from the engine

• Excessive smoke from the exhaust

• Poor acceleration and loss of power

• Frequent overheating despite coolant levels

• Metal shavings in the oil

In some cases, it’s more cost-effective to replace the engine than to repair internal damage.

Buying a Replacement 2016 Kia Sedona Engine

Looking for a 2016 Kia Sedona engine for sale? Here's what you need to know before buying:

Engine Compatibility

Ensure that you're buying the G6DH 3.3L V6 engine, which is the correct engine code for the 2016 Sedona. Check your VIN and match engine specs.

Used vs. Remanufactured Engines

If you're on a budget, a low-mileage used engine is a good option. But if you want long-term peace of mind, a remanufactured engine is worth the investment.

Where to Buy

You can find replacement 2016 Kia Sedona engines from:

• Reputable Online Retailers (like Turbo Auto Parts or Car-Part.com)

• Certified Salvage Yards

• eBay Motors (only with verified sellers and warranties)

• Local Mechanics or Engine Rebuilders

Maintenance Tips to Extend Engine Life

Whether you’re installing a new engine or keeping your current one running smoothly, here are some maintenance tips specific to the 2016 Kia Sedona engine:

1. Change Oil Frequently

Use full synthetic oil and change every 5,000–7,500 miles. GDI engines are sensitive to oil sludge buildup.

2. Use Top Tier Fuel

Higher-quality gasoline can reduce carbon buildup and improve combustion efficiency.

3. Check Coolant and Thermostat

This engine is prone to overheating if the thermostat fails. Keep coolant levels optimal and flush the system every 60,000 miles.

4. Clean the Throttle Body

A dirty throttle body can lead to poor idle and engine hesitation. Clean it during major services.

Engine Swap Considerations

Swapping in a different engine (like from a different Kia model) is technically possible, but not advisable for most people. The 2016 Sedona’s 3.3L V6 is tightly integrated with the vehicle’s ECU, transmission, and emission controls.

If you're set on doing a swap for performance or budget reasons, work with a mechanic experienced in Hyundai-Kia platforms and engine wiring.

Final Thoughts

The 2016 Kia Sedona engine is a reliable workhorse that delivers power, comfort, and decent fuel efficiency. Whether you're maintaining your current engine or replacing it with a new or used one, understanding the specs, common issues, and replacement costs can save you time and money.

With proper care, the 3.3L V6 in the 2016 Sedona can easily run for 200,000 miles or more. And if you're shopping for a replacement, there's a healthy supply of used and remanufactured engines available—just be sure to buy from a trusted source and confirm compatibility.
