2021 Hyundai Tucson Engine Warranty Extension & DTC P1326

Why This Matters

Hyundai Motor America (HMA) has reached a class action settlement regarding an alleged engine defect in certain Hyundai vehicles, referred to as "Class Vehicles." This defect can lead to serious issues such as sudden engine seizure, stalling, engine failure, and in some cases, engine fire. The settlement aims to provide benefits to owners and lessees, including an extended warranty for engine repair or replacement.

What's Being Addressed

This document, identified as TXXM / T6G, outlines the Engine II Class Action Settlement, which extends warranty coverage and details a Dealer Best Practice for engine inspection and replacement. The settlement addresses concerns related to connecting rod bearing wear or damage, which can trigger the Check Engine warning lamp with DTC P1326, abnormal engine noise, or a no crank/no start condition. While the settlement covers a broader range of Hyundai models and years, this specific communication applies to the 2021 Hyundai Tucson.

Symptoms

Owners of affected vehicles, such as the 2021 Hyundai Tucson, may experience several symptoms related to the engine defect. These include the "Check Engine warning lamp illuminated" on the dashboard. The engine might also exhibit "abnormal noise" or a "no crank/no start condition." These symptoms are often indicative of underlying issues like connecting rod bearing wear or damage.

Fault Codes / DTCs

The primary diagnostic trouble code (DTC) associated with this engine issue is:

This DTC, P1326, specifically points to a problem detected by the Knock Sensor Detection System (KSDS), which monitors for abnormal engine vibrations that could indicate connecting rod bearing issues.

Diagnosis and Trigger Conditions

To properly diagnose the issue and qualify for benefits under the settlement, customers are strongly encouraged to complete the Knock Sensor Detection System (KSDS) software update, referred to as Service Campaign 966 or 982. Completion of KSDS by November 4, 2023, is required for claims-made benefits and generally for the extended warranty. Dealers must submit a Warranty Prior Approval (PA) request for all applicable vehicles within the extended warranty period that exhibit the outlined conditions.

Repair Procedure Summary

Dealers will follow a specific process to address the engine defect. This involves inspecting the vehicle to determine the extent of the damage. Based on the inspection results, the repair may include replacing the engine or updating the engine ECU software. Technicians should refer to T6G TSB#22-01-0232H-2 for detailed procedures. If the Check Engine light is on with DTC P1326, or if there's abnormal noise or a no crank/no start condition, the TSB procedures must be followed.

Required Tools or Parts

Technicians will need to refer to TSB 22-01-024H-2 for specific parts ordering information and labor operation codes. Special Service Tools (SST), such as a bearing clearance tester, may also be required to perform accurate diagnostics and repairs. Your dealership must have the necessary SSTs and know how to calibrate them.

Important Warnings and What Owners Should Know

• Prior Approval Required: Regardless of KSDS completion, dealers must always submit a Warranty Prior Approval request for all applicable vehicles within the extended warranty period. A Warranty Prior Approval (PA) must be submitted for all vehicles exhibiting the conditions described in this best practice document.
• KSDS Completion: Completion of Service Campaign 966 (Knock Sensor Detection System) by November 4, 2023, is required for claims-made benefits. KSDS is also generally required for the extended warranty benefit under the settlement.
• Evidence of Fire: If there is any evidence of a fire or other components needing replacement due to fire, dealers must disclose all affected parts to PA as part of the engine PA review process and do not perform any diagnosis or repairs until further directed.
• Maintenance Records: If maintenance neglect is suspected, dealers will ask customers to provide oil change receipts. Customers will have up to 10 business days to gather these records.
• Alternative Transportation: It is recommended to provide customers with a Service Rental Car (SRC) if their vehicle is brought in for the T6G TSB 22-01-023H-2 inspection. All SRC or Rental claims will be reimbursed regardless of the PA's decision to cover engine replacement.
