What's wrong?
The Hydraulic Clutch Actuator, or HCA, on the 2017 Kia Niro is part of the hybrid propulsion system. It uses hydraulic oil pressure to engage and release the clutch, which helps move power through the drivetrain as the vehicle switches between electric and engine operation.
On affected Niros, burrs inside the HCA housing damage the inner oil seal. Once that seal is damaged, oil leaks into the cap area instead of staying inside the actuator. Oil in that area can reach electrical parts and cause a short, which is the failure Kia identified in recall 18V257.
The warning sign for owners is the HEV warning light. If that light comes on, the hybrid system has detected a fault and the vehicle needs dealer attention.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific crossover is included.
What's the safety risk?
An electrical short in the HCA area increases the risk of a fire. If the HEV warning light comes on, pull over when safe, shut the vehicle off, and contact a Kia dealer before continuing. Schedule the recall inspection soon. Repair is free at any franchised Kia dealer.
What should I do?

- Contact a franchised Kia dealer to schedule the free HCA cap inspection and repair that addresses oil leaking into the cap area and the electrical-short fire risk.
- Bring the recall notice if Kia mailed one. If not, reference recall number 18V257 and Kia recall SC163 when you call.

- Park the vehicle and call the dealer if you smell burning or see smoke before the repair is complete.
What happens at the repair
At the dealer, a Kia technician inspects the Hydraulic Clutch Actuator caps for leaked oil. If oil has collected in the cap area, the technician replaces the HCA assembly, or replaces the HCA cap and adds sealant. Parts and labor are free under the recall. If you already paid for this repair, Kia's General Reimbursement Plan covers documented repair expenses already incurred. Ask Kia customer service or the service desk how to submit your repair paperwork.
