Original wording in English

TECHNICAL SERVICE BULLETIN: SERVICE ACTION: 8-SPEED DUAL CLUTCH TRANSMISSION (DCT) S/W LOGIC IMPROVEMENT (SA526) - This bulletin supersedes SA502. This bulletin provides information to update the software logic of the A/T system on certain 2022-2023MY K5 (DL3a) and Sorento (MQ4a) vehicles equipped with Theta 2.5L T-GDI engine and 8-Speed DCT. The affected vehicles may exhibit an abnormal shifting condition while driving, due to the amount of clutch oil flow consumption immediately after starting. In some cases, the cluster may display a transmission error message and/or MIL ON with DTC P086800 stored.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
