We’re riding safer than ever thanks to today’s automotive technologies. Steering assist is a system you’ll find on newer cars. There’s a problem with this system, though. To avoid danger, you must act quickly when you see the message “Steering Assist is Reduced Drive with Care”.
My goal with this article is to give you a general understanding of what the Steering Assist system is, along with a few valuable tips on how to use it and what to do when you see warning signs. Furthermore, I discuss how to fix some of the most common causes, how this can be achieved, and what you may need to pay as a result. This article concludes with questions and answers regarding this system that are frequently asked.
What is the Steering Assist System?
Power steering systems of today’s vehicles can be used with Steering Assist. Modern automobiles come with this advanced safety system. A safety package or standard program may come with the program, or it may be an option.
An electric motor provides steering assistance with the help of the electrical system, which is connected to the steering wheel. Drivers apply torque or effort to the wheel through various sensors. A Steering Assist system provides additional help if more needs to be added.
It’s not completely autonomous but it helps with steering. You won’t be able to enjoy a nap while the technology takes over your steering. The driver must still input information. As well, most cars let you turn it off when you don’t need it.
Is it Safe To Drive With Care If Steering Assist Is Reduced?
It tells you there’s a problem with the Steering Assist program when you see the Steering Assist Is Reduced Drive With Care message on your dashboard. Steering Assist won’t do anything when you need it.
Hence, you should Drive With Care when the warning light appears. It’s up to you to keep the steering wheel torqued properly without any assistance. You may not notice a big difference when backup protection is gone, but if you’re used to it, you will miss it.
Reduced Drive With Care Message Is the Cause of Steering Assist
Low battery voltage and a stored trouble code in the steering assist control module are the most common causes of the “Steering Assist Is Reduced, Drive With Care” message. Power steering control modules or thermostats can also be the cause.
Steering Assist Is Reduced Drive With Care could be caused by the following causes:
1. Bad car battery or low battery voltage
If the power supply is interrupted, the steering assist will malfunction. These advanced systems are powered in a variety of ways. In order for the vehicle to run, it must be supplied with power by its battery. Several of today’s safety systems can malfunction if their batteries have been disconnected or are dying.
Likewise, loose or corroded connections or wires can cause the same problems. Drive With Care message is most often caused by low battery voltage, which causes steering assist to be reduced. Later on, I will discuss more in detail the trouble code stored in the steering assist control module.
2. Old Trouble Code Stored
In the steering assist control module, a trouble code will be stored if the voltage drops low or if an electrical failure occurs. The steering assist is reduced Drive With Care warning message will display whenever there is a trouble code stored in this control module.
In this case, clearing the trouble codes in this control module can rectify a temporary low voltage or other electrical issue.
3. Stuck Open Thermostat
When your scan tool indicates steering assist is reduced and a P0128 code, this indicates a cooling system issue, which can cause steering assist to be reduced. This issue is addressed in a technical service bulletin for GMC, Cadillac, or Chevrolet vehicles.
Coolant flows through the radiator and engine through the engine thermostat. Maintaining the engine’s normal operating temperature is its responsibility.
Fluid will continue to flow unchecked through the thermostat if it gets stuck open. Engine temperature will be too low as a result. An error code will be generated as a result of the incorrect temperatures causing the Steering Assist system to malfunction.
4. Broken Temperature Sensor
It is also important to check the sensor when it comes to engine temperature. Sensors measure the temperature of the engine to determine its temperature. An engine that is hot reads a high sensor, and the opposite is true if a low sensor is read.
A mechanical failure, such as I discussed earlier, or a broken sensor may be to blame when the car runs long but the gauge still reads low. Steering Assist will malfunction if the ECM does not receive the appropriate data.
5. Defective Steering Assist Module
A steering assistant or power steering module is fitted to most automobiles for the purpose of handling steering assist functions.
Modules and sensors may be damaged, requiring replacement in some cases. Steering Assist Modules need to be updated or may not be functioning properly other times. There are usually other issues associated with this problem as well.
What to do if your steering assist isn’t working
Make sure your battery is charged and in good shape so you get rid of the Steering Assist is Reduced Drive With Care message. A power steering assist control module trouble code should be read from an OBD2 scanner.
1. Check The Battery
When you see Steering Assist Is Reduced on your dashboard, the first thing you should do is check your car’s battery. It is possible to measure the voltage with a multimeter or with a car battery tester. When the engine is running, make sure the alternator charges the battery.
Battery replacement may be the best option for you if you see anything wrong with the battery or if it is over five years old. Ensure that the battery terminals are not corroded.
2. Read & Clear Trouble Codes
The codes set in the computer should have been activated with the Steering Assist message. A high-end code scanner will allow you to read the DTCs, assisting you in finding the problem. It is important to make sure that you have a code scanner that works with these new systems, but not all code scanners are compatible.
It is better to reset the codes if there are numerous trouble codes. If the message doesn’t come back after a short drive, you may need to take the car for a spin. The Steering Assist Is Reduced message can often be fixed just by changing the battery and clearing the codes.
You can begin your research online as soon as you receive the trouble code. There are a lot of top DTCs in our Mechanic Base database, so you can easily figure out what to do to fix them.
2. Replace Broken Parts
Knowing what you need to do, you gain a better understanding of the code. Repairs may be possible in your garage, depending on what needs to be fixed.
If you do not have much experience with changing batteries, you shouldn’t have too much trouble. A thermostat, cooling fan, or temperature sensor can also be replaced if you have the right tools and expertise.
3. Consult Mechanic
The car may need to be taken to a repair shop if your diagnostic abilities haven’t provided a solution. It is easy to figure out what’s wrong in many shops because they have advanced tools.
Furthermore, if you cannot handle the repair at home, you may need to hire a professional shop. ECMs are not something you should try to update or replace at home, for instance. The dealership is often required to assist with this kind of work.

Steering Assist Repair Costs Reduced
Depending on what went wrong, your repair costs will vary. Furthermore, the cost varies depending on whether the work can be performed by you or whether you must take the vehicle to a mechanic. The following estimates will assist you in planning your budget.
Changing a battery does not require any labor on the electrical side. It can either be done by yourself or it can be done for free by your local auto parts store when you purchase a battery from them. There is only one cost, which is usually $75 to $350 for a new battery. A process such as this could take much longer if you have to find and correct a problem with the electrical system.
Temperature sensors or thermostats are usually replaced for $150 to $350. Since the part is inexpensive, most of this cost is labor.
In addition, the steering system diagnostics can be time-consuming. In some cases, it can be difficult to repair. As you can see, this rarely happens, so you won’t have to worry about it.
Tesla vehicles reduce steering assist. Why?
Tesla vehicles come equipped with Autosteer, which is Tesla’s Steering Assist program. A lane marker may be missing or the road may be narrow, causing a warning to appear. There may also be a mechanical failure that requires repair in these instances, but they are usually temporary and resolve themselves.
