What Does This Error Mean?

Hyundai EPS warning light means the electric power steering system has detected a fault. Steering still works but may feel heavy. A restart often clears a temporary EPS fault — if it returns, the EPS torque sensor, motor, or control unit needs professional diagnosis.

Affected Models

Hyundai Tucson
Hyundai Elantra
Hyundai Kona
Hyundai i30
Hyundai Santa Fe
Hyundai Ioniq 5
Hyundai Ioniq 6

Common Causes

Temporary EPS software fault — clears on restart
Weak battery or low voltage causing EPS control unit startup fault
EPS torque sensor failure — sensor measuring steering effort has failed
EPS motor overtemperature from heavy repeated full-lock use
EPS control module fault — less common but documented on high-mileage Tucson models

How to Fix It

Restart the engine.

Switch off the engine, wait 30 seconds, and restart. Hyundai EPS software faults triggered by voltage transients or cold starts typically clear on restart. If the warning clears and does not return, the fault was transient — monitor for recurrence over the following week.
Check the battery and alternator.

A weak 12V battery causes EPS faults, particularly on cold mornings when the battery is at its lowest. Have the battery load-tested if it is over 4 years old. Check for corroded battery terminals — a poor connection causes voltage drop during startup that can trigger EPS faults.
Check for Hyundai EPS recall.

Hyundai has issued recalls and TSBs for EPS software faults on several Tucson, Elantra, and i30 model years. Check your VIN at hyundaiusa.com or your regional Hyundai portal for open recalls. An EPS software update from a dealer may resolve persistent warnings without hardware replacement.
Read EPS fault codes.

Use a Hyundai-compatible OBD-II scanner to access the EPS control module. Hyundai EPS codes appear as C24XX series codes. Code C2401 indicates an EPS torque sensor fault; C2400 indicates the EPS motor — both require replacement of the EPS rack assembly at a Hyundai-authorized workshop.
Allow EPS to cool after heavy steering use.

Repeated full-lock turns during parking maneuvers can overheat the EPS motor, triggering the warning as a thermal protection response. Stop the parking maneuver, switch off the engine, and allow 10 minutes for the motor to cool. After restarting, the EPS should return to full assistance. If the warning appears regularly during normal parking, the EPS motor may be failing.

When to Call a Professional

If the EPS warning persists after a restart and the steering remains noticeably heavier than normal, have the EPS fault codes read with a Hyundai-compatible scanner.
