What Does The EPS Light Mean On A Hyundai Elantra?

Most car owners dread warning lights on their vehicle’s dashboard. They can activate for all kinds of problems and almost always represent something that needs to be repaired. 

So what does the EPS light mean on a Hyundai Elantra?

The EPS light on a Hyundai Elantra means that the system has detected a problem with the electronic power steering (EPS). Unlike hydraulic power steering, the vehicle uses an electric motor to make steering easier. When a problem with the EPS is detected, it can be a safety issue to continue to drive the vehicle, as most people do not know how to drive safely without power steering. 

EPS Lights On Vehicles

Modern vehicles use power steering to make steering the car easier. The system is designed so the steering wheel is easy to turn, and it takes much less energy to point the wheels where you want them. 

Anyone who has driven without power steering can attest to how much strength it takes to turn the wheel without it. 

There are two main types of power steering in modern vehicles: hydraulic and electronic.

In a hydraulic system, problems usually arise when a leak causes low fluid levels, and the pressurized system becomes unbalanced.

Electronic power steering systems don’t use pressurized fluid to help you steer but instead rely on an electric motor. 

A control module reads inputs from the angle of the steering wheel, and an electric motor assists in turning the wheels. 

The EPS Light is a function connected to your vehicle’s electronic power steering system; it activates when an issue is detected and often means your vehicle requires maintenance. 

Why Would the EPS Light Turn On?

Faults or problems with the battery or alternator can cause the EPS light to come on. 

The connection between parts may have come loose and sent a problem indicator to the vehicle’s computer. 

Other malfunctions in the system could also be the reason for an activated EPS light.

Normal wear and tear can cause different parts of the system to malfunction or deteriorate, causing it to fail or not work properly.

Sometimes, the light may turn on if you’ve recently had to jump-start your car or disconnect the battery. 

Is it Safe to Drive With the EPS Light On?

It is possible to drive with the EPS light on, but that doesn’t mean it’s safe. 

An EPS light could indicate your power steering is failing, making steering, turning, and controlling the vehicle more difficult. 

It is especially dangerous for power steering to fail when driving at higher speeds where you won’t be able to react effectively to prevent an accident. 

If you’re close to home when the EPS light activates, you could proceed cautiously, but be sure to go slowly. 

Even if you seem to have full control when the light is on, you shouldn’t be driving. The system could fail at any time, rendering the vehicle impossible to control. 

If your EPS light comes on, you will need to take it to a qualified mechanic. 

How Do I Fix EPS Problems?

To fix EPS problems yourself, you first want to check the connections to the battery for visible signs of wear. If you find some, that could be the main issue. 

Sometimes, you can resolve the issue by turning your vehicle off and on again. This usually works best when the light comes on after a battery change or jumpstart. 

If the light persists and you find no wear on the connections, you’ll need to take the vehicle to a mechanic. 

Even if the light deactivates by restarting the vehicle, you should still take it to get checked out. Underlying issues with the system could be the real cause, and it’s better to err on the side of caution. 

How Much Does an EPS System Cost To Fix?

The overall cost to repair your electronic power steering system can vary greatly and depends on what part of the system is malfunctioning. 

Replacing or fixing connections between the system and the battery could cost under $200. 

Unfortunately, other parts of the system are much more expensive to repair. 

Replacing the control module on an EPS system runs between $800 and $1,000.

Replacing the motor (of the system) will usually run between $400 and $600. 

These costs don’t factor in labor to diagnose the problem, nor any taxes or additional fees.

Can EPS Affect the Starter in a Vehicle?

Since an EPS light may turn on after jump-starting a vehicle, some people believe the system is connected to the ignition and may cause your car not to start. 

In most cases, the EPS function has no impact on the vehicle’s ability to start or even drive. 

Occasionally, if the system is degraded enough, the vehicle may not start as a safety precaution. 

Your car’s computer may disable the ignition and fuel system if it detects the vehicle is not safe to drive. 


The EPS Light in a Hyundai Elantra turns on when an issue is detected within the electronic power steering system. 

The problem could be as minor as a connection to the battery wearing out or may be an indication that your car requires a new control module. 

If your EPS light turns on, do not continue driving the vehicle. Take it to a certified mechanic to diagnose the issue so you can safely get back on the road.
