PI1805: the 2019-specific knock-sensor campaign, and the limp mode it causesmajor
- 2.4L GDI Theta II
- 2.0L Turbo GDI Theta II
Kia ran a dedicated Product Improvement Campaign for this model year. Its owner letter reads: Kia is performing a software update on all 2019 model-year Sportage vehicles equipped with 2.4-litre GDI and 2.0-litre turbo GDI engines to protect the engine from excessive connecting rod bearing damage, free of charge. GDI means Gasoline Direct Injection; the connecting-rod bearings are the metal shells the piston rods spin on. The software is KSDS, the Knock Sensor Detection System. Kia's bulletin describes what a trigger looks like: the engine warning light blinks continuously, the car enters Limp Home Mode, code P1326 is stored, and revs are capped at roughly 1,800 to 2,000. A 2019 owner in the federal file describes exactly that — "vehicle suddenly entered recall limp-mode due to the ongoing engine campaign." A follow-up bulletin, PI1805Y/Z, tells dealers what to do when a 2019 Sportage comes back with P1326 after the software was installed. Ask for proof PI1805 was performed and that no P1326 is stored.
