2021 Hyundai Tucson Engine Warranty Extension TSB

Why This Matters

Hyundai has announced a significant warranty extension, identified as TXXM/T6G, for engine repair or replacement due to connecting rod bearing wear. This is crucial for owners of affected vehicles, including the 2021 Hyundai Tucson, as it provides extended coverage for a potentially serious engine issue. The extended warranty applies to both original and subsequent owners, offering peace of mind for a common concern.

Symptoms

Owners might notice several symptoms if their vehicle is experiencing issues related to connecting rod bearing wear. These can include the "Engine warning lamp illuminated with DTC P1326", the engine exhibiting "abnormal noise", or a "no crank/no start" condition. These indicators suggest a problem with the engine's internal components that warrants immediate attention.

Fault Codes / DTCs

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

Code	Description
P1326	Engine Bearing Inspection/Engine Replacement

This code specifically points to a problem with the engine's connecting rod bearings, prompting the need for inspection and potential repair or replacement.

Warranty Extension Details (TXXM/T6G)

The warranty coverage for engine damage or malfunction resulting from connecting rod bearing wear has been extended to 15 years or 150,000 miles from the date of original retail delivery or date of first use, whichever occurs first. This extended warranty, known as TXXM/T6G, is valid for both original and subsequent owners. It is important to note that commercial entities, individuals involved in buying/selling/leasing/renting motor vehicles, and salvaged vehicles are ineligible for this extended coverage.

Important Warnings and Owner Information

Owners are strongly encouraged to complete the Knock Sensor Detection System (KSDS) software update, which was communicated under Service Campaign 966 or 982. This software update is a requirement for coverage under the extended warranty. Vehicles previously recalled under Recall 198 and Recall 209 are exempt from the KSDS requirement. Dealers are instructed to always submit a Warranty Prior Approval request for all applicable vehicles within the extended warranty period.

Crucially, if there is evidence of fire or other components needing replacement due to fire, owners should be aware that dealers must disclose all affected parts to Warranty Prior Approval (PA) and are directed not to perform any diagnosis or repairs until further directed.

Repair Procedure Summary

When a vehicle, such as the 2021 Hyundai Tucson, presents with an illuminated engine warning lamp, DTC P1326, abnormal engine noise, or a no crank/no start condition related to connecting rod bearing wear, technicians are directed to follow the procedures outlined in TSB 22-01-023H-2. This TSB details the inspection process for engine bearing issues and the subsequent steps for engine replacement if necessary. Dealers must obtain a Warranty Prior Approval (PA) before proceeding with any repairs under this extended warranty. Technicians performing this repair should be at a Hyundai Expert level or higher.

Owner Action

If you own an affected Hyundai vehicle and experience any of the described symptoms, especially an illuminated engine warning lamp with DTC P1326, contact your authorized Hyundai dealer immediately. The dealer will inspect your vehicle and determine eligibility for the extended warranty. Hyundai recommends providing alternative transportation, such as a Service Rental Car (SRC), if your vehicle needs to remain at the dealership overnight or for an extended period. Ensure the Knock Sensor Detection System (KSDS) software update (Campaign 966 or 982) has been completed on your vehicle, as it is a requirement for warranty coverage. If your vehicle has not received KSDS, Hyundai will still consider eligibility for the warranty extension, but the KSDS completion is crucial.
