Upon customer's request ONLY, the Technical Service Bulletin \(TSB\) 25\-01\-089H provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti\-theft decals on the front windows. This repair procedure is being provided in addition to the previous Anti\-Theft software provided under Service Campaign 993 \(TSB 24\-01\-009H\-1\).
- [25\-01\-089H DN](/bulletins/11027034.md), 2026-01-06, Other: ELECTRICAL SYSTEM. In addition to the Anti\-Theft software provided under Service Campaign 993 \(TSB 24\-01\-009H\-1\), a zinc reinforced ignition cylinder protector hardware upgrade is being made available to customers upon request. This supplemental security measure is to be installed at the ignition switch location and provides additional protection against the social media theft method. Vehicles not equipped with an immobilizer during production at the factory are eligible. The repair procedure shall be performed and claimed upon customer request only. Any future repairs to these vehicles in which an installed ignition cylinder protector impacts required parts and/or labor, shall be covered by HMA. Please see TSB 25\-01\-089H for details.

- [P33 OL](/bulletins/11026704.md), 2025-12-19, Other: ELECTRICAL SYSTEM. In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti\-theft software, we’ve developed a new zinc\-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above \(“Subject Vehicle”\) was not factory\-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.
