This bulletin provides information related to a software update to the Engine Control Unit (ECU) to
install the Knock Sensor Detection System (KSDS) in order to protect the engine from excessive
connecting rod bearing damage. This update is for some 2019MY vehicles listed below:

The KSDS detects vibrations indicating the onset of excessive connecting rod bearing wear. It is
designed to alert the driver at an early stage of bearing wear before the occurrence of severe engine
damage, including engine failure. If vibrations caused by bearing wear start to occur, the Malfunction
Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Limp Home Mode. This will
reduce further damage to the engine and ensure that the vehicle occupants are not exposed to the risk
of a more severe engine failure. At that time, Diagnostic Trouble Code (“DTC”) P1326, specific to the
KSDS, will be recorded in the ECU. The vehicle can continue to be operated for a limited time in Limp
Home Mode, but it will accelerate slowly and have a reduced maximum speed. Also, engine RPMs will
be limited to approximately 1800-2000 RPM.
Kia
is requesting the completion of this Product Improvement Campaign on all affected vehicles. Before
conducting the procedure, verify the vehicle is included in the list of affected VINs. Also, please have
your KDS connected to the internet regularly to get the latest software updates available.
NOTICE
To assure complete customer satisfaction, always remember to refer to WebDCS
Warranty Coverage (validation) Inquiry Screen (Service → Warranty Coverage →
Warranty Coverage Inquiry) for a list of any additional campaigns that may need to be
performed on the vehicle before returning it to the customer.
