The 2019 knock-sensor campaign covers some cars, not allmajor
- 2.4L GDI Theta II
This is a real difference from 2016 to 2018 and it is worth checking by VIN rather than assuming. Kia's Product Improvement Campaign PI1805 — a Product Improvement Campaign is a free fix offered outside the safety-recall system — installs the Knock Sensor Detection System on this year, but Kia's owner letter describes the scope as "a software update on some 2019 MY Sorento vehicles equipped with 2.4L Gasoline Direct Injection (GDI) engines to protect the engine from excessive connecting rod bearing damage." The word is *some*, where the 2016 to 2018 letter said *all*. A follow-up bulletin, PI1805Y/Z, tells dealers what to do "if, after installation of the KSDS, any one of the subject vehicles below return to the dealer with Diagnostic Trouble Code (DTC) P1326 (Knock Signal Range/Performance)." And the money question has the same answer as every other Sorento year in this range: Kia's engine short-block warranty extension, WTY008, covers 2012 to 2014 model years only. There is no extension on a 2019 engine.
