Service bulletins for the 2016 Hyundai Tucson

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.

172 on file from NHTSA, as of 2026-10-19.

Bulletins, newest first
26-EM-016H TSB2026-10-14. Service bulletin. ENGINE. Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.
26-EM-015H TSB2026-10-13. Service bulletin. ENGINE. Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.
26-EM-014H TSB2026-09-22. Service bulletin. ENGINE; ELECTRICAL SYSTEM. Some Tucson (TL) vehicles equipped with a 2.0L engine may exhibit a continued DTC P132600 after an ECM logic update has been performed per TSB 24-01-068H, Engine Monitoring Logic (Service Campaign 966). This bulletin provides instructions to inspect and resolve other engine mechanical issues and if DTC P132600 remains, then a procedure and manual mode passwords are given to perform the update again in manual mode to resolve this condition.
DTN DL2026-05-08. Other. AIR BAGS. The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.
DTN DCS2026-05-08. Other. AIR BAGS. The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.
26-01-033H TSB2026-03-31. Warranty extension. ENGINE. This TSB references the Op codes to use for claim submission and the Parts required based on the vehicle’s inspection results from TSB 22-01-023H-2 (DTC P1326 – Engine Bearing Inspection/Engine Replacement) or the latest version.

25-01-089H DCS2026-01-06. 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.

25-01-089H DN2026-01-06. 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 OL2025-12-19. 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.
