# Service bulletin 20\-01\-022H\-1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## Other bulletins for the same vehicles and component

- [26\-EE\-007H TSB](/bulletins/11034027.md), 2026-06-23, Service bulletin: ELECTRICAL SYSTEM. Some Palisade \(LX2\), Tucson \(NX4\), and Tucson Hybrid \(NX4 HEV\) vehicles may experience battery drain due to continuous operation of the cooling fan after vehicle ignition has been turned off, potentially resulting in a no\-start condition. The continuous cooling fan operation is caused by a stuck relay in the engine room PCB block. This bulletin provides instructions to replace the engine room PCB block to ensure the proper operation of the cooling fan.
- [9C2 060518](/bulletins/11033705.md), 2026-06-06, Service campaign: ENGINE; ELECTRICAL SYSTEM. Following completion of Service Campaign 9C2 \(Theta II Emissions Improvement\), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation. If present, this condition is expected to occur only within approximately the first 1\-3 minutes after engine start, while the catalyst is reaching its normal operating temperature.
- [9C2 DCS 260518](/bulletins/11033701.md), 2026-06-06, Service campaign: ELECTRICAL SYSTEM; ENGINE. Following completion of Service Campaign 9C2 \(Theta II Emissions Improvement\), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation.

- [26\-01\-013H\-2 DN](/bulletins/11033700.md), 2026-06-06, Service campaign: ELECTRICAL SYSTEM; ENGINE. Certain Santa Fe \(TMA\), Santa Fe Sport \(AN\), Sonata \(LFA\), and Tucson \(TL\) vehicles equipped with Theta II engines may exhibit elevated engine\-out emissions. The California Air Resources Board has determined that these vehicles may be releasing air pollutants which exceed Federal and California standards.
- [26\-01\-013H\-2 TSB](/bulletins/11033699.md), 2026-06-06, Service campaign: ENGINE; ELECTRICAL SYSTEM. Certain Santa Fe \(TMA\), Santa Fe Sport \(AN\), Sonata \(LFA\), and Tucson \(TL\) vehicles equipped with Theta II engines may exhibit elevated engine\-out emissions. This bulletin provides instructions for updating the Engine Control Module \(ECM\) to address this condition.
- [Z01 Letter](/bulletins/11033679.md), 2026-06-06, Warranty extension: AIR BAGS; ELECTRICAL SYSTEM. Certain 2012 – 2017 model year Accent, 2012 – 2017 model year Azera, 2013 – 2018 model year Santa Fe Sport, 2013 – 2019 model year Santa Fe, and 2012 – 2017 model year Veloster vehicles may exhibit an intermittent airbag warning light and diagnostic trouble codes \(DTCs\) may be set. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the Occupant Classification System \(OCS\)/Occupant Detection System \(ODS\) under these conditions has been extended to 18 years/unlimited mileage from the date of original retail delivery or date of first use \(whichever occurs first\) and is valid for original and subsequent owners.
- [25\-01\-089H DCS](/bulletins/11027035.md), 2026-01-06, Other: ELECTRICAL SYSTEM. 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.
- [25\-01\-089H TSB](/bulletins/11027033.md), 2026-01-06, Other: ELECTRICAL SYSTEM. This bulletin provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti\-theft decals on the front windows.
- [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.
