Identify the Source of the Noise
 

• Check if the clicking sound occurs only when turning the steering wheel left or right.
• Determine if the noise happens when the vehicle is stationary, moving, or both.
• Listen for the noise's location, whether it is from the area directly under the steering wheel or closer to the wheels and suspension.

 
Check for TSBs (Technical Service Bulletins)
 

• Contact a Hyundai dealership or search online for any TSBs related to steering wheel noises specifically for 2011–2016 Elantra models.
• Official TSBs might provide specific fixes recommended by Hyundai for known issues.

 
Inspect the Clock Spring
 

• The clock spring is a spiral wound wire that allows the steering wheel to turn while maintaining electrical connectivity to the airbag and controls.
• A defective clock spring can cause clicking noises. Carefully remove the steering wheel cover to inspect the clock spring for damage or wear.
• If faulty, the clock spring should be replaced. This procedure should be done with care, following proper safety precautions, as it involves airbag components.

 
Check the Steering Coupler
 

• A common issue with Elantras from this period is the deterioration of the steering coupler.
• The steering coupler is a rubber piece that can wear out, leading to clicking or knocking noises. Hyundai offers a redesigned part for replacements.
• Replacing the coupler often requires removing the steering column. It is advisable to consult a repair manual or a professional mechanic for this task.

 
Inspect the Suspension Components
 

• While less common, it's possible that suspension components like struts, tie rods, or sway bar links may be causing the noise.
• Raise the vehicle and inspect these components for any signs of wear, damage, or loose connections.
• Replace any worn or damaged suspension parts as needed.

 
Consult with a Professional Mechanic
 

• If the source of the clicking noise cannot be determined or resolved, it is best to consult with a professional mechanic.
• A mechanic can perform a more thorough inspection and use diagnostic tools to identify the underlying issue.
