Wondering what it means when your Acura MDX prompts you to “Acura MDX Check SH AWD System“?

This is an alert from your vehicle’s Super Handling All-Wheel Drive (SH-AWD) system, a sophisticated technology designed to enhance driving performance by providing optimal traction and control.

It typically indicates that the system has detected some sort of irregularity or issue which requires attention. If this warning light illuminates, don’t panic!

We’re here to guide you through understanding more about the SH-AWD system in your Acura MDX, and what steps should be taken upon seeing this alert.

How the SH AWD System Works?

Acura’s Super Handling All-Wheel Drive (SH-AWD) is a smart system that directs power to the wheels in need. It improves handling and stability, keeping you safe on any road condition.

  • Intelligent Power Distribution: The system can send up to 70% of engine torque to the rear wheels.
  • Torque Vectoring: Depending on driving conditions, it can direct up to 100% of those resources left or right.

Here’s how:

  1. Under normal cruising, your vehicle operates mainly in front-wheel drive for fuel efficiency.
  2. When acceleration happens, torque is evenly distributed between front and rear axles for balanced performance.
  3. During hard cornering or slippage detection, more power shifts towards rear axle with higher distribution towards outer wheel for enhanced control.
Driving ConditionFront:Rear Torque SplitLeft:Right Torque Split
Normal Cruising90:10Not Applicable
Hard Cornering30:70More towards Outer Wheel

Remember this isn’t something you’ll have to manually control—it’s all handled automatically based on real-time analysis of your driving conditions!

Common Issues with the SH AWD System:

The SH-AWD (Super Handling All-Wheel Drive) system in an Acura MDX is a sophisticated piece of technology that provides superior handling and traction. However, like any other component, it can run into issues.

Here are some common problems:

  • Malfunction Indicator: An illuminated ‘Check SH AWD System’ warning light on your dashboard may indicate potential problems.
