SUBJECT: HIGH PRESSURE FUEL PIPE INSPECTION
AND REPLACEMENT (RECALL 207)
This TSB supersedes TSB# 21-01-055H-1 to revise the high-pressure fuel pump flange
nut torque specification listed in pages 5, 8, and 9.
Description: On certain 2021-2022MY Santa Fe (TMa) and Sonata (DN8a) vehicles equipped
with 2.5T GDI engines, the fuel pipe connecting the high-pressure fuel pump to the fuel rail may
have been installed with insufficient torque during assembly. Additionally, certain fuel pipes could
have been produced outside of Hyundai’s specification for concentricity. A fuel pipe that has been
installed with insufficient torque or improper concentricity could allow fuel to leak at its connections
increasing the risk of an engine compartment fire. Follow the procedure outlined in this TSB to
inspect, tighten and/or replace, the fuel pipe as needed.
Applicable Vehicles:
Certain 2021-2022MY Santa Fe (TMa) vehicles equipped with 2.5T GDI engines.
Certain 2021-2022MY Sonata (DN8a) vehicles equipped with 2.5T GDI engines.

NOTICE
*******************************************************************************************************
This notice applies to your Hyundai, VIN:
Dear
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Hyundai has decided that a defect which
relates to motor vehicle safety exists in your vehicle, with the VIN shown above. As part of its continued investigation, Hyundai is expanding
recall campaign 206, a safety recall to repair a fuel pipe in certain model year 2021 Hyundai Santa Fe vehicles equipped with 2.5-litre
Turbo engines and produced for sale in the U.S. market. The expansion adds additional 2021 – 2022 Hyundai Santa Fe and 2021 – 2022
Hyundai Sonata vehicles equipped with 2.5-litre Turbo engines produced by HMMA for sale in the U.S. and Canadian markets to the
recall population.
What is the problem?
The fuel pipe connecting the high-pressure fuel pump to the fuel rail may have been insufficiently tightened during assembly. Additionally,
certain fuel pipes could have been produced outside of Hyundai’s specification for concentricity. A fuel pipe that has been installed with
insufficient tightness or improper concentricity could allow fuel to leak at its connections, increasing the risk of an engine compartment
fire.
What will Hyundai do?
Your Hyundai dealer will confirm the fuel pipe’s production lot date code. Fuel pipes confirmed to be from the affected lot will be replaced
and tightened to the proper torque setting. Fuel pipes not originating from the affected lot will be inspected for fuel leaks. If a leak is found,
the fuel pipe will be replaced and tightened to the proper torque setting. If no fuel leak is found, the fuel pipe will be tightened to the proper
torque setting. This procedure will be performed at NO CHARGE to you.
What should you do?
Please contact your nearest Hyundai dealer to schedule the recall repair as soon as possible.
If the Malfunction Indicator Light is illuminated in your vehicle, you should seek service at your Hyundai dealer as soon as possible. The
actual time required to perform the repair will take approximately one hour or less, however your vehicle may be needed longer. Therefore,
we recommend scheduling a service appointment to minimize inconvenience.
If you have other questions
If you require further assistance, you may contact the Hyundai Customer Care Center at 1-855-371-9460. If you believe that the dealer or
Hyundai has failed or is unable to remedy the defect within a reasonable time, you may submit a complaint to the Administrator, National
Highway Traffic Safety Administration, 1200 New Jersey Avenue S.E., Washington, D.C. 20590, or call the toll free Vehicle Safety Hot Line
at 1-888-327-4236 (TTY: 1-800-424-9153), or go to https://www.safercar.gov.
Thank you for your attention to this important safety matter. We apologize for any inconvenience this may have caused you.
