On the 2012-2016 Kia Soul 1.6L GDI, nHTSA recall 19V120000 (Kia SC176) covers 2012-2016 Soul vehicles with the 1.6L GDI engine. Excessive exhaust-gas temperature can damage the catalytic converter, leading to abnormal combustion, piston damage, connecting-rod failure, stall or fire. Kia’s later SC176Y bulletin addresses certain previously repaired vehicles with P0420, with or without a P030X misfire code.
Loss of power, abnormal combustion or engine damage
How to Fix
Check the VIN and campaign history with Kia. SC176 calls for the Catalytic Overheating Protection ECU update and replacement of a damaged converter or engine as necessary, free of charge. For an eligible SC176Y vehicle with P0420, the dealer follows Kia’s compression-test flow before choosing converter or engine replacement. Do not infer P0430 or purchase radiator, coolant or generic exhaust parts from this page.

On the 2011-2013 Kia Soul, the Hydraulic Electronic Control Unit (HECU/ABS module) can develop an internal electrical short (fluid leakage plus localized PCB melting was found in retrieved units), producing excessive current that can cause an engine-compartment fire while parked or driving. NHTSA recall 23V-652 covers 349,309 2011-2013 Souls equipped with Electronic Stability Control, part of the broader Kia/Hyundai 'park outside' fire-risk campaign. Owners were told to park outside and away from structures until repaired.
Recall remedy: dealer installs new fuse(s) in the HECU electrical circuit to prevent an overcurrent condition, free of charge under NHTSA 23V-652 (Kia SC284). Interim notices mailed late 2023; remedy available as of mid-2024.
On the 2010-2013 Kia Soul, kia TSB CHA074 covers 2010-2013 Soul vehicles in its listed production range and attributes a knock or click while turning at a stop to premature wear of the MDPS motor’s flexible coupling. Kia WTY013 separately extended flexible-coupling coverage to 10 years/unlimited mileage for 2012-2013 Soul vehicles; it does not extend every other MDPS component or the 2010-2011 vehicles.
Common Symptoms
Clicking or knocking from the MDPS while turning the steering wheel at a stop
How to Fix
Have the noise diagnosed against CHA074 and the exact VIN. If premature coupling wear is confirmed, follow Kia’s Soul-specific procedure to replace only the improved flexible coupling. Check WTY013 eligibility for a 2012-2013 vehicle. Do not order a generic coupler or replace the full MDPS column without the current Kia parts catalog, fitment and steering-service procedure.
