Infiniti QX50 2019-present Drivetrain Specifications

The 2019-Present Infiniti QX50 features a front-engine, all-wheel drive (AWD) system as standard. This drivetrain is powered by a 2.0L VC-Turbo engine, which delivers 268 horsepower and 280 lb-ft of torque. The AWD system is designed to provide optimal traction and stability in various driving conditions, automatically distributing torque between the front and rear wheels as needed. This setup is compatible with Infiniti's Intelligent All-Wheel Drive technology, enhancing performance and safety.

Regular maintenance for the QX50's drivetrain includes checking and replacing the differential fluid every 30,000 to 50,000 miles, inspecting the driveshaft and CV joints for wear, and ensuring the AWD system functions correctly. Infiniti recommends servicing the drivetrain components during routine maintenance intervals, such as oil changes and tire rotations. Adhering to the manufacturer's maintenance schedule helps prevent premature wear and ensures optimal performance.

Replacing drivetrain components on the QX50 requires specialized tools and expertise. Begin by lifting the vehicle securely and removing the underbody panels. For the driveshaft, disconnect the universal joints and remove the bolts securing it to the differential. For the AWD system, drain the differential fluid, remove the axles, and unbolt the differential assembly. Always refer to the service manual for torque specifications and proper reassembly procedures. Professional assistance is recommended for complex tasks.

If the AWD system malfunctions, first check for dashboard warning lights, such as the AWD or check engine light. Inspect the fluid levels in the differential and transfer case, and ensure there are no leaks. Test the system by driving on slippery surfaces to verify torque distribution. If issues persist, use an OBD-II scanner to read error codes and consult the service manual for troubleshooting steps. Professional diagnosis may be required for electrical or mechanical failures.

To optimize the QX50's drivetrain, use high-quality synthetic fluids for the differential and transfer case. Regularly inspect and maintain the drivetrain components to prevent wear. Ensure tires are properly inflated and rotated to reduce strain on the AWD system. Avoid aggressive driving on uneven terrain to minimize stress on the drivetrain. Upgrading to performance-oriented components, such as a limited-slip differential, can also enhance handling and traction.
