The IVT (Intelligent Variable Transmission) in your 2020 Seltos has a distinctive operational sound, but a new or increasing whine deserves attention. CVT-type transmissions operate differently than conventional automatics, and their sounds reflect that difference.
Normal IVT Sounds vs. Problems
Normal sounds:
- Slight humming during acceleration
- Engine RPM rises then holds steady during acceleration
- Brief noise during cold starts
Problem indicators:
- Loud whining that increases with speed
- Whine that changes pitch under load
- New sound that wasn't present before
- Grinding or metallic sounds
- Whine accompanied by shuddering
What Causes CVT Whining
- Low fluid level - Inadequate lubrication creates noise
- Degraded fluid - Worn fluid loses its properties
- Belt/chain wear - The variable pulley system wearing
- Bearing wear - Internal bearings developing play
- Pump cavitation - Fluid pump struggling
Fluid Is Critical
CVT-type transmissions are extremely sensitive to fluid condition. The IVT requires specific CVTF fluid—using incorrect fluid or neglecting changes dramatically accelerates wear and creates noise.
Diagnostic Steps
- Check IVT fluid level and condition
- Note when whining occurs—acceleration, deceleration, constant
- Does sound change with engine RPM or vehicle speed?
- Any warning lights or codes?
- Is the whine new or gradually increasing?
What You Can Do
- Have fluid level and condition checked
- Consider fluid service if due or overdue
- Document the sound (video recording helps)
- Have dealer evaluate if sound is abnormal
Repair Costs
- IVT fluid service: $150-$300
- Valve body service: $800-$1,500
- IVT replacement: $3,500-$6,000
Kia covers the IVT under the 10-year/100,000-mile powertrain warranty.
