Summary
A class action lawsuit against Hyundai
Motor America (âHMAâ) alleges that certain Hyundai
vehicles (âClass Vehiclesâ) were manufactured, marketed, sold, and/or leased with an engine defect that can result in sudden engine seizure, stalling, engine failure, and in some circumstances, engine fire, and that some owners and lessees of Class Vehicles have been improperly denied repairs under warranty. Neither HMA nor Hyundai
Motor Company have been found liable for any of the claims alleged in the lawsuit. The parties have instead reached a voluntary settlement (the âSettlementâ) to avoid lengthy litigation and to provide owners of Class Vehicles certain benefits.

Description of Engine II Class Action Settlement
A class action lawsuit against Hyundai
Motor America (“HMA”) alleges that certain Hyundai
vehicles (“Class
Vehicles”) were manufactured, marketed, sold, and/or leased with an engine defect that can result in sudden
engine seizure, stalling, engine failure, and in some circumstances, engine fire, and that some owners and
lessees of Class Vehicles have been improperly denied repairs under warranty. Neither HMA nor Hyundai![]()
Motor Company have been found liable for any of the claims alleged in the lawsuit. The parties have instead
reached a voluntary settlement (the “Settlement”) to avoid lengthy litigation and to provide owners of Class
Vehicles certain benefits.
Beginning in May 2023, customers affected by the proposed Settlement will begin receiving notice of the
Settlement by mail and email and may start directing questions to dealers. In response to those questions,
dealers should direct customers as follows:

7:00PM EST.
Completion of Service Campaign 966 (Knock Sensor Detection System or “KSDS”) by November 4,
2023 is required for claims-made benefits. KSDS is also generally required for the extended warranty
benefit under the Settlement. See Settlement website above for further details.
TXXM Warranty Extension Benefits
For eligible class vehicles, the warranty coverage for engine repair or replacement regarding engine damage or
malfunction 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, and is valid for original and subsequent owners
(TXXM).
NOTE: Commercial entities and individuals engaged in the buying, selling, leasing, or renting of motor
vehicles, as well as salvaged vehicles, are ineligible for the extended warranty.
Description of Campaign

KSDS Requirements
Customers are strongly encouraged to complete the Knock Sensor Detection System (KSDS) software (Service
Campaign 966 or 982), which is being communicated to owners as a requirement for coverage under the
extended warranty. With the settlement being at the preliminary approval stage, Prior Approval (PA) will
exercise discretion in approving engine repair or replacement even if engine damage or malfunction has
occurred before KSDS installation. Previously recalled vehicles under Recall 198 and Recall 209 are exempt
from the KSDS requirement.
The settlement is scheduled to receive final approval at the end of 2023. An update is expected to be issued at
a later date that will update the KSDS installation policy.
NOTE: Regardless of KSDS completion, dealers should always submit a Warranty Prior Approval
request on all applicable vehicles within the extended warranty period.
Before Proceeding with T6G or TXXM
Make sure to confirm diagnosis meets warranty eligibility requirements relating to the conditions outlined within
this document. If a vehicle is brought in for an engine condition unrelated to T6G (e.g., oil consumption), please
follow the proper engine diagnosis procedures, and refer to standard warranty policies and procedures.
If there is evidence of a fire or other components needing replacement due to fire, please 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.
Vehicle Maintenance Review Requirements
When there is a reasonable basis to suspect maintenance neglect based on an inspection of the engine
condition:
1. Dealer must inform customer that maintenance neglect is suspected and ask the customer to provide all
oil change receipts.
2. Dealer must document how and when this was communicated to the customer in the “Maintenance
Review” portion of the PA form.
3. Dealer and HMA will provide the customer up to 10 business days (exact amount of days dependent on
the customer’s requested time) to gather records before making a final decision.
NOTE: HMA may make a decision prior to 10 business days if a customer acknowledges any
available records have already been provided or if no records are available.
4. HMA will make all final decisions related to engine condition and advise the dealer accordingly.
2
Alternative Transportation
It is recommended to place the customer in a Service Rental Car (SRC) if the vehicle is brought in for the
(T6G) TSB 22-01-023H-2 inspection.
NOTE: All SRC or Rental claims will be reimbursed regardless of PA’s decision to cover the engine
replacement.
If a SRC is not available, please provide the customer with alternative transportation (3rd Party Rentals and
Rideshares).
Customer Talk Tracks
“The Technician will check your vehicle for any Diagnostic Trouble Codes and inspect your vehicle’s engine
during the visit to determine if any repairs will be needed. Subject to Knock Sensor Detection System
completion, your vehicle’s engine warranty has been extended to 15 years or 150,000 miles, whichever comes
first, for engine concerns related to connecting rod bearing wear. If your vehicle has not received Knock
Sensor Detection System, Hyundai
will still consider eligibility for the warranty extension for the time being.
First, we will need to diagnose your vehicle and then we can submit the information to determine if the repairs
are covered under the warranty extension.”
“I will follow up with you and provide a status update along with any information about your vehicle I have from
the Technician as soon it becomes available. If it is determined that the repairs are not covered by the
Warranty Extension, I will call you with a detailed report of the findings and provide you with an estimate for the
repairs before continuing any further. In instances of suspected neglect, you may be asked to provide oil
change maintenance records. You will have up to 10 business days to provide them. I will keep you updated
throughout the process.”

Yes
No – Please ensure all open campaign(s)/recall(s) are identified and completed by the dealership.
Readiness: Are parts in stock to complete this campaign?
Yes
No – It is highly recommended to have parts on-hand when customer arrives to the dealership,
especially if customer has made appointment beforehand and to minimize dealership traffic. Order
parts and obtain an estimated time of arrival (ETA) as soon as possible.
Further:
Technicians completing these campaigns should be minimum Certified level and completed
Engine Technology – Classroom (#SVCET28_208) or the Engine Tech vILT Final Exam – Web

calibrate the BCT. See TSB # 21-GI-009H. or latest version.
Reception: Did you explain to the customer the expected repair time based on the repair?
Yes
No – Customer should be given an estimated time of when his/her vehicle is completed so the
customer can plan the rest of their day away from the dealership.
Further:
Check WebDCS for applicable open and completed recalls and service campaigns, e.g., KSDS
on Campaign 966 or 982.
If the MIL is illuminated and has triggered DTC P1326 and/or the engine is exhibiting abnormal
noise or no crank/no start condition related to connecting rod bearing wear or damage, then
follow the procedures outlined in T6G TSB#22-01-0232H-2.
Print a copy of the Service Process Results Worksheet for the technician to complete and attach
to the RO. This will help determine the appropriate parts and labor op codes to use.
Repair: Did you provide the customer with an eMPI?
Yes
No
Further:
Prep for warranty submission:
2 claims may be submitted for this campaign:
1 for inspection
1 for engine replacement
If a part needs replacement as a direct result of failure caused by Campaign T6G related
engine failure, or if additional labor is required:
Submit a separate claim using the same RO # AND
Submit with 21101NTT using the engine Causal Part # associated with T6G Op
Code AND
Ensure part replacement and punch times match the labor performed along with
service manager’s signature approving the TT time
If a part is found in need of replacement and failure is NOT caused by T6G but is still
under warranty, submit a separate claim using the same RO.
Technicians should follow T6G TSB#22-01-0232H-2 or the latest version.
