2010-2021 Hyundai Engine Bearing TSB 26-01-033H

Hyundai Technical Service Bulletin (TSB) 26-01-033H is a comprehensive reference guide for Operation (Op) codes and part numbers essential for processing claims under Service Campaign T6G. This bulletin, dated March 2026, supersedes the previous TSB 22-01-024H-2. It includes updated information for 2019-2021 model year (MY) Tucson (TL) vehicles, specifically regarding the Reman engine 21101-2EG18FFHRM, and revises the 'Information' box to refer to the latest Hyundai Policy & Procedures when ordering an engine.

The primary purpose of TSB 26-01-033H is to streamline the claim submission process for dealers performing repairs related to engine bearing issues. It outlines the specific Op codes and required parts based on the inspection results from TSB 22-01-023H-2, which focuses on "Engine Bearing Inspection/Engine Replacement" and the diagnostic trouble code (DTC) P1326. Owners experiencing symptoms like "Abnormal Engine Noise" in their Hyundai vehicle should be aware of this campaign and the diagnostic procedures involved.

Understanding Service Campaign T6G and DTC P1326

Service Campaign T6G is initiated to address potential engine bearing issues that can lead to significant engine problems. The diagnostic process for this campaign is detailed in TSB 22-01-023H-2, which identifies DTC P1326 as a key indicator of potential "Engine Bearing Inspection/Engine Replacement" necessity. This DTC, along with symptoms such as "Abnormal Engine Noise," signals to technicians that further inspection of the engine's internal components is required.

The Hyundai engine bearing TSB emphasizes that any repair work under this field action requires both a reported condition consistent with the symptoms outlined in TSB 22-01-023H-2 and dealer confirmation of those symptoms. This ensures that repairs are performed only when genuinely necessary, based on a thorough diagnostic process.

Symptoms of Engine Bearing Issues

The most common symptom that would lead a technician to consult TSB 26-01-033H and initiate Service Campaign T6G is "Abnormal Engine Noise." This noise can manifest in various ways, such as knocking, ticking, or rattling sounds coming from the engine. If your Hyundai vehicle develops such noises, it is crucial to have it inspected promptly. The presence of DTC P1326 further corroborates the need for an "Engine Bearing Inspection/Engine Replacement" procedure.

Technicians will perform a series of checks, including assessing external engine damage, checking the oil dipstick for metal particles, and performing a crank rotation test. The outcomes of these inspections, such as "Crank Rotation (NO)" (engine seized) or "BCT RESULT (NO PASS)" (bearing clearance test failure), dictate the specific Op codes and parts required for the repair.

Important Warnings for Owners and Technicians

Several critical advisories are highlighted in TSB 26-01-033H to ensure proper procedure and claim submission:

• Diagnosis Requirement: "This field action requires both a reported condition consistent with the symptoms outlined in TSB 22-01-023H-2 and dealer confirmation of those symptoms before any repair work is performed." This means a vehicle cannot simply receive an engine replacement without proper diagnosis.
• Engine Ordering Policy: "Consult the latest Hyundai Warranty Policy and Procedures when ordering an engine." This ensures compliance with warranty guidelines for parts procurement.
• Claim Submission for Related Malfunctions: If a part needs replacement and the "malfunction is directly caused by Campaign T6G related engine failure," or if additional labor is required, a separate claim must be submitted using the same repair order number and the engine causal part number associated with the T6G Op Code.
• Out-of-Warranty Repairs: "If the affected part(s) are out of warranty, submit a Prior Approval (PA) request for goodwill consideration prior to performing the work." This protects owners from unexpected charges for goodwill repairs.
• PA for Engine Replacement: "PA Approval ONLY required for Op Codes with engine replacement." This streamlines the approval process for less extensive repairs.
• ECM Update Requirement: "Campaign 966 Engine ECM update is only required if new software is available." Technicians should not perform unnecessary ECM updates.
• Separate Claim for ECM Update: "Please submit an additional campaign claim under Campaign 966 for performing software update if new software is available." This ensures correct billing for the software update.
• Hybrid Starter Generator (HSG) Note: For 2016MY Sonata Hybrid/Plug-in (LF HEV/PHEV) models, if the newly installed long block engine is not compatible with the existing HSG, replacement of part number 373902E930-SJ may be required. This can be claimed under 'NTT'. The TSB advises referring to Note 3 on page 2 for claiming directions.

Understanding Op Codes and Part Numbers for Repair

TSB 26-01-033H provides extensive tables detailing the specific Op codes, estimated Op times, and corresponding part numbers for various repair scenarios under Service Campaign T6G. These tables are organized by model year, model, and drivetrain (FWD/AWD), covering a wide array of Hyundai vehicles from 2010-2021, including:

• 2010-2012 Santa Fe (CM) 2.4L
• 2010-2013 Tucson (LM) 2.4L
• 2011-2015 Sonata Hybrid (YF HEV) 2.4L
• 2014-2015 Tucson (LM) 2.0L
• 2014 Elantra Coupe (JK) 2.0L
• 2014-2016 Elantra (MD) 2.0L
• 2014-2017 Elantra GT (GD) 2.0L
• 2018-2020 Elantra GT (PD) 2.0L
• 2016-2021 Tucson (TL) 2.0L
• 2016-2019 Sonata Hybrid Plug-in (LF HEV/PHEV) 2.0L
• 2012-2017 Veloster (FS) 1.6L

For each specific scenario, the TSB lists a unique Op code (e.g., 10D223AA, 10D223MC) and an associated Op time in man-hours (M/H), which is crucial for warranty claim processing. The descriptions are highly detailed, specifying the exact conditions under which each Op code applies. Examples include:

• "Replace Engine (OE) + New ECM S/W Available (NO)"
• "Abnormal Engine Noise (YES) + Refer to HTSS (YES)/Submit PA + ECM Update (YES)*"
• "(SEIZED): EXTERNAL DAMAGE (NO) + OIL DIPSTICK (YES) + CRANK ROTATION (NO) + SUBMIT PA"

Key components and part numbers referenced throughout the bulletin include:

• Engines: Various engine part numbers are listed, such as 21101-2G404FFF (OE) and 21101-2EG18FFHRM (Remanufactured engine for 2019-2021MY Tucson). These numbers vary significantly based on the specific vehicle model, engine type, and whether it's an original or remanufactured unit.
• Service Kits: Complementary service kits, like 21111-2G4S2FFF, 21111-2EG01FFF, 21111-2BS01FFF, and 21112-2BS02FFF, are often required alongside engine replacements. For ULEV/SULEV/PZEV vehicles, technicians must check the underhood emission label to order the correct service kit.
• Knock Sensors: Part numbers such as 39250-2G100, 39250-2E000, and 39250-2B000 are specified for knock sensor replacements, particularly when "Abnormal Engine Noise" is detected without an immediate need for engine replacement.
• Fuel Tubes: Certain repairs, especially for specific engine types, may require new fuel tubes, with part numbers like 35305-2E510FFF and 35305-2B000FFF.

ECM Software Updates (Campaign 966)

An important aspect of these repairs, particularly for the Hyundai engine bearing issue, is the potential need for an Engine Control Module (ECM) software update. This is managed under Campaign 966. TSB 26-01-033H clarifies that the ECM update is only required if new software is available. If an update is performed, it must be submitted as a separate campaign claim under Campaign 966 Op Codes, which are identified with an asterisk (*) in the replacement Op code tables.

Claim Submission Process and Warranty Information

For technicians, the TSB provides detailed instructions on claim submission and warranty information. This includes guidelines for submitting separate claims for inspection, engine/knock sensor replacement, and additional labor or parts.

• Inspection Claim: One claim for inspection.
• Replacement Claim: One claim for replacement of engine/knock sensor, as needed.
• Additional Claims: If a part replacement is needed due to a malfunction directly caused by Campaign T6G related engine failure, or if additional labor is required, a separate compiled claim must be submitted. This claim should use the same repair order number and include the 21101NTT causal part number associated with the T6G Op Code. Accurate punch times and service manager approval are required for labor claims. If part replacement does not require additional labor, a system minimum of .00 labor time with a quantity of 1 should be used.
• Out-of-Warranty Parts: If a part is found to be out of warranty, a Prior Approval (PA) request for goodwill consideration must be submitted before performing work.
• PA for Engine Replacement: PA approval is ONLY required for Op Codes that involve engine replacement.

Special attention is given to "Seized Cases" for specific models:

• 2010-2012MY Santa Fe (CM) 2.4L & 2010-2013MY Tucson (LM) 2.4L engines ONLY: These models have specific replacement Op codes for seized cases that involve "engine replacement from the front." These Op codes are identified with '(SEIZED)' in their description. An additional 1.2 M/H (man-hours) is provided for these specific models due to the extra labor needed to remove both the engine AND transmission. For all other models, engine replacement is performed from the bottom using the regular pull-down method.

What Owners Should Do

If you own a Hyundai vehicle from the 2010-2021 model years affected by Service Campaign T6G and experience "Abnormal Engine Noise" or suspect engine bearing issues, it is imperative to contact your authorized Hyundai dealer immediately. Describe the symptoms clearly to the service advisor. The dealer will perform the necessary diagnostic procedures, including checking for DTC P1326, to confirm the condition and determine the appropriate repair as outlined in TSB 22-01-023H-2 and referenced in this Hyundai engine bearing TSB 26-01-033H.

Ensure that any repairs are performed according to the guidelines of Service Campaign T6G. If your vehicle is out of warranty, discuss the possibility of a Prior Approval (PA) request for goodwill consideration with your dealer before any work begins.
