Kia Sorento 2016-2020 Drivetrain Specifications

The 2016-2020 Kia Sorento offers front-wheel drive (FWD) and all-wheel drive (AWD) options. The AWD system is electronically controlled and can distribute torque between the front and rear axles as needed. The drivetrain is paired with either a 2.4L inline-4, 2.0L turbocharged inline-4, or 3.3L V6 engine, depending on the trim. Transmission options include a 6-speed automatic or an 8-speed automatic for certain trims.

Regular maintenance for the Kia Sorento drivetrain includes checking and replacing the transfer case and differential fluids every 30,000 to 60,000 miles, depending on driving conditions. Inspect the AWD system for leaks or damage during routine service. Ensure the driveshaft and CV joints are lubricated and free of wear. Follow the owner's manual for specific intervals and procedures.

To replace drivetrain components, first, lift the vehicle securely and remove the wheels. For AWD models, disconnect the driveshaft and transfer case. Replace worn components like CV axles or differential gears, ensuring proper torque specifications. Reassemble in reverse order, refill fluids, and test the system. Always refer to the service manual for detailed instructions and safety precautions.

If your drivetrain is making noise, inspect for worn CV joints, damaged driveshafts, or low fluid levels. Check for leaks in the transfer case or differential. Listen for grinding or clunking sounds, which may indicate internal damage. If the issue persists, consult a professional mechanic or refer to the service manual for diagnostic steps.

To optimize drivetrain performance, use high-quality fluids and lubricants recommended by Kia. Regularly inspect and maintain the AWD system, ensuring proper tire alignment and pressure. Avoid excessive towing or off-road use unless equipped for such conditions. Consider upgrading to performance parts if available, but ensure compatibility with your vehicle's specifications.
