Steering assist is the newest technology modern automakers have implemented for safety. The electric power steering system is connected to the hydraulic power steering system, which helps the driver to steer the vehicle easily.

When you see the “steering assist is reduced drive with care” message, know there is a failure in the engine control module, electrical wiring has a problem, thermostat failure, and several other issues we will look at later.

As technology evolves, modern car manufacturers have embraced it to enhance safety. For this reason, vehicles have been equipped with computer systems that enable the driver to get updates on the dashboard. Thankfully, the number of road accidents has reduced and increased safety, according to WHO.

So, let’s learn more about the steering assist system, and the steering assist is reduced drive with care dashboard message.

What Is Steering Assist?

The steering assist is part of the modern car’s power steering system. It contains two systems that help it to become effective; the hydraulic power steering system and the power steering assist system.

The system allows drivers to avoid unintentional deviations from their highways lanes. This power steering system controls the hydraulic fluid pump to pressure the hydraulic fluid. As a result, it eases the steering movement to make driving smooth.

Magnifying pressure from the slight movement of the steering transfers energy to the car tires. And finally, driving becomes smooth and enjoyable.

What Does Steering Assist Reduced Mean?

The steering assist is reduced drive with care message is triggered by the engine control module (ECM). The ECM’s job is to receive signals from sensors in various components and determine if their working condition is right.

The message appears on the dashboard when the ECM detects interruption between the communication modules or the wrong signals from sensors monitoring the steering system. Normally, this message is triggered by inaccurate power steering fluid and coolant temperature readings.

Which Vehicles Have Steering Assist is Reduced Issue?

Nearly all modern vehicles have a steering assist system. And since this electronic aid uses a computer system and sensors to detect the steering wheel position, it can malfunction anytime.

Here are some of the vehicles that have been proven to develop steering assists problems:

  • Tesla Model X
  • Chevy Traverse
  • Chevy GMC
  • Chevy Malibu
  • Cadillac XT5
  • GMC Sierra
  • GMC Acadia
  • Chevy Cruze
  • Chevy Tahoe
  • Ford Fusion
  • Chevrolet Silverado

The Tesla steering assist reduced together with other modern car models has been a big issue. Earlier, Tesla recalled 40,168 S and X models manufactured between 2017 and 2021. This was due to the loss of power steering assist caused by faulty software.

What Are The Signs Of Steering Assist Is Reduced Issues?

Apart from the steering assist is reduced drive with care message, there are various signs you can learn to know your steering system is faulty. Why look at the signs when you have the updates on the dashboard? The display message may sometimes fail, or the signs may help you avoid trouble earlier, even before the message pops.

So, here are the signs of steering assist failure:

  • The steering becomes stiff, requiring more effort to steer the car.
  • You get the wrong coolant temperature alerts from the Engine Control Module (ECM).
  • Whining noise from the steering queue.
  • The steering wheel vibrates continuously.
  • The car drifts slightly even when you steer it straight in the lane.
  • Steering fluid leakages, thus low levels.

Reasons Why the Steering Assist Is Reduced Message Comes On

Once you get the steering assist is reduced drive with care; know that there are several causes. And identifying the cause is the first step to solving the issue. So, below are some of the possible causes of the steering assist failure:

1. ECM and its Liability to Error and Fault

The steering assist system is interconnected to the Electronic Control Module (ECM). The ECM is responsible for managing all the electrical functions in a car. The problem happens when the coolant temperature changes affecting how the module carries the signals. The module sensors become incompetent as the fluid hardens, making the steering assists ineffective.

2. Frequent Use of Steering Assist

Turning on the steering assist option for an extended duration when the vehicle isn’t in motion can cause the steering assist error message. Just as with all computer systems, it can develop faults due to frequent use. But in this situation, it’s very simple to fix by switching off the car and turning it on.

3. Steering Fluid Leaks

The steering hydraulic pump has some fluid that helps to turn the car wheels. When the pump and the hoses wear, fluid leaks, making the levels low. Low fluid levels can trigger less pressure when the steering is turned, making driving challenging. This triggers the steering assist error message.

4. Change in the Electric Supply System of Vehicles

The steering system uses an electric motor. This motor delivers power to increase pressure on the hydraulic fluid when the steering is turned. If the wiring is disconnected, the assist system displays an error message. The same happens when the car battery is low, or many appliances are connected to the system.

5. The Engine Thermostat is Stuck Open

The engine thermostat regulates the flow and the temperature of the engine coolants. When the thermostat is stuck open, excessive fluid gets through the engine lowering the temperatures below average. This can cause the steering assist system to malfunction and display an error message.

6. The Engine Cooling Fan is Stuck on a High Speed

When the cooling fan does not correspond to the engine speed, it might run faster and cool the engine rapidly. This makes the hydraulic grease stiff, and steering the car becomes harder. In this situation, the error message may pop up.

7. Inferior Power Steering Fluid Pump

The power steering pump pushes the fluid to deliver the pressure required for the steering. If the pump is faulty, the steering becomes stiff, and the error message displays on the dashboard. The power steering pump and the hoses must be regularly checked when servicing the car.

How To Fix Steering Assist Is Reduced Warning?

Once you have identified the cause of the steering assist error message, it can be very easy to fix. Every problem has its approach strategy. But below, we have provided general procedures on how to reset steering assist is reduced drive with care.

1. Add Hydraulic Fluid to the Steering System

Low hydraulic fluid levels is the leading cause of steering assist failure. You can check the fluid level and top it up to keep the system efficient. However, it’s essential to check the owner’s manual and note the type of fluid and the volume to add. Also, inspect the cause of fluid loss because if the hoses are leaking, you may not solve the problem by topping it up. You can take your car to the mechanic if the problem is complicated.

2. Check the Car’s Electrical System

Electrical system is vital in the steering system because it supplies power to the motor. Once the system fails, check the wiring connections, the battery condition, and the alternator. Then, replace or fix any components that you find non-functional.

3. Fix the Faulty Module

The steering assist module controls the power provided to the steering system. It’s part of the electrical system but a bit complex due to an integrated computer system. As the module ages, it can develop many faults. But you can replace it, fix the faulty components, or update the software.

However, if you have less knowledge about software and electricals, have a professional do the work.

Frequently Asked Questions (FAQs):
