PRODUCT IMPROVEMENT CAMPAIGN (PI1802A1) UPDATE - OWNER LETTER - Dear Kia Optima Owner:
As we previously notified you, Kia Motors America, Inc. is conducting an important Product Improvement Campaign to perform a software update on some 2014 MY Optima vehicles equipped with 2.4L Gasoline Direct Injection (?GDI?) engines, and all 2015 MY Optima vehicles equipped with 2.4L GDI and 2.0L Turbocharged GDI (?T-GDI?) engines to protect the engine from excessive connecting rod bearing damage by utilizing a Knock Sensor Detection System (?KSDS?).
Our records show that the KSDS software was recently installed in your vehicle and we want to thank you for your quick action. Since then, Kia has become aware that the KSDS software version installed in your vehicle has an error and requires the installation of a new corrected software.
