P1326 on Hyundai
Hyundai and Kia: the knock sensor detection system (KSDS) has picked up vibration that matches abnormal connecting rod bearing wear
Severity: Stop — don't drive this car
Hyundai and Kia set P1326 when the KSDS detects vibration from connecting rod bearing wear that can lead to engine failure, and Hyundai lists no-crank/no-start among the symptoms. The car is put in a reduced-power protection mode only so it can be driven a limited distance to a dealer. Do not keep driving normally.
