Whining noise when you turn? Power steering explained

A whine or groan that gets louder as you turn — especially at full lock — usually points to low power-steering fluid or a failing power-steering pump. Air or a leak in the system is a common root cause.

Is it safe to drive?

Have new steering noise checked. If steering suddenly becomes heavy or a steering warning tells you to stop, pull over safely and arrange assistance.

What to tell the repair shop

  • Tell the shop whether the steering effort changed when you heard the noise.
  • Record any steering warning message. Check your owner’s manual for what it means on your vehicle.
  • Mention any leak you saw while parked. The steering system type determines which checks apply.
