C1603Power steering thermal protection active

• Hyundai/Kia code · Power steering
• Lights a warning lamp

How the car detects it

The electric motor got hot from a lot of steering at low speed (for example repeated parking manoeuvres) and assistance is reduced to protect it. Nothing needs replacing; it recovers as the motor cools. When the power steering limits or stops its assistance, the steering becomes heavy but still works mechanically.

What you may notice

• Temporarily heavier steering

Likely causes

• LikelyHeavy steering use at standstill or low speed
