Consumer Description

The Exhaust heat recovery system has a valve that can malfunction and allows coolant to leak into the exhaust and ignite it into the atmosphere. It can cause misfires in the engine, there are technical service bulletins (TSB 212 and Pitstop Tech bulletin PS709 that are attached to this report) that have more information on this issue. This can drain the coolant from the system and cause engine overheating issues. Some shops may misdiagnose it as a head gasket problem. This is a common problem for Kia Niro's 2017-2022. A new heat exchanger as of now costs $3000 brand new from the OEM and Kia is very strict about how they apply their warranty to any kind of part. Please can you help remedy this issue for Niro owners.
