NOTE 2: If a part is found in need of replacement while performing this Recall Campaign and the affected part is still under warranty, submit a separate warranty claim using the same Repair Order.  If the affected part is out of warranty, submit a Prior Approval Request for goodwill consideration prior to performing the work.

 

Service Procedure:

 

  1. Scan for DTCs in the BMS System using the GDS.

 

NOTICE

Ensure all Freeze Frame Data and Information Codes are collected if any DTCs are detected in the BMS System.

 

If DTCs are detected in the BMS System, collect all related Freeze Frame Data and all Information Codes for the DTC.

  • For DTC P1AA600:
    • Replace the high voltage battery according to procedures in TSB 20-EE-001H-2 (or latest revision).
    • When repairs are completed and there are no DTCs, continue to Step 2.
  • For other DTC, follow the related shop manual to repair the vehicle then continue to Step 2.

 

If no DTCs are detected in the BMS System:

Proceed to Step 2.

 

  1. If there are no DTCs in the BMS System, update the ECU software using the GDS for the following systems. Reference the GDS Information section for Event #.

 

NOTICE

Do not proceed with ECM updates before diagnosing and repairing all DTCs in the BMS System.

 

Note: Check Campaign 960 completion status on VIS. If Campaign 960 was completed, a software update for (c) and (d) is not required since these systems were previously updated during Campaign 960.

 

NOTICE

Perform all ECM updates in AUTO mode first. If AUTO mode is not successful then MANUAL mode can be used.

 

a) BMS (Battery Management System)

b) VCULDC (Vehicle Control Unit & Low DC-DC Converter)

c) IGPM (Integrated Gateway Power Module)

d) MCU (Motor Control Unit)

 

Refer to TSB 15-GI-001 for the general GDS Mobile ECU update procedures.

 

! WARNING

THE 12V BATTERY VOLTAGE CHECK IS CRITICAL FOR THIS MULTI-ECU UPDATE AS IT  COULD DRAW DOWN THE 12V BATTERY WHILE THE IGNITION IS ON. 

 

STOCK VEHICLES ARE PRONE TO LOW BATTTERY CONDITION. OPERATE A STOCK VEHICLE AT READY ON FOR 20 MINUTES PRIOR TO STARTING THE MULTI-ECU UPDATE.

 

THIS WILL ENSURE 12V BATTERY WILL BE CHARGED TO AN ADEQUATE LEVEL, PREVENTING POTENTIAL UPDATE FAILURE OR CONTROLLER DAMAGE.

 

! WARNING

If a low battery warning message appears  on the GDS, operate the vehicle in Ready mode for at least 20 minutes to ensure the 12 V battery is adequately charged before performing any software updates.

 

  1. After successful completion of the applicable system updates, search all systems for DTCs.

 

If no DTC are found, the procedure is complete.

 

NOTICE 

Refer to TSB 20-EE-001H-2 for high voltage (HV) battery approval guidelines.

 

DTC, Freeze Frame Data (FFD), current BMS data screens, and other information must be submitted according to the procedures in TSB 20-EE-001H-2 (or latest revision).

 

If DTCs are detected in the BMS System, collect all related Freeze Frame Data and all Information Codes for the DTC.

  • For DTC P1AA600:
    • Replace the high voltage battery according to procedures in TSB 20-EE-001H-2 (or latest revision).
    • When repairs are completed and there are no DTCs, follow Step 2 to update the BMS software, if applicable.
  • For other DTC, follow the related shop manual to repair the vehicle.

 

GDS Information:

NOTICE

All ECM updates should be performed in Auto Mode first. If the ECM update starts but then fails in Auto Mode, perform these updates in Manual Mode.

Q&A

Q1: What is the issue?

A1: The high-voltage battery system in the subject vehicles might contain certain electrical deficiencies, such as internal damage to certain cells of the lithium-ion battery and/or faulty battery management system (“BMS”) control software that could increase the risk of an electrical short circuit after fully charging the Li-ion battery. Hyundai is continuing to actively investigate this condition for identification of a specific root cause.

 

Q2: What are the affected vehicles?

A2: The subject vehicles include model year 2019-2020 Hyundai Kona electric vehicles (“EV”) built between August 28, 2018 and March 2, 2020 by Hyundai Motor Company (“HMC”) for sale in the U.S. market. The affected population was determined based on suspect production lot information provided by the supplier and vehicle assembly records.

 

Q3: What is the safety concern?

A3: An electrical short in Li-ion battery could increase the risk of a fire.

 

Q4: Have there been any accidents or injuries?

A4: To date, Hyundai is not aware of any crashes or fires in the U.S. attributable to this condition. Hyundai is aware of at least nine fires in South Korea, two in Canada, and two in the European market.

 

Q5: What will be done during the recall service at the dealer?

A5: Customers are advised to park their vehicles outdoors and/or away from structures until their vehicle is remedied. Hyundai is planning to notify owners to bring their vehicles to the nearest Hyundai dealership for inspection and replacement of the Li-ion battery, if necessary. As an added level of protection, Hyundai is also planning on updating the BMS software to allow for detection of abnormalities in the high-voltage battery system while parked. This current TSB addresses the software update and inspection, including the repair process for those vehicles that have the DTC P1AA600 found during inspection. The remedy procedure will be performed at no charge. Hyundai will provide reimbursement to owners for repairs according to the plan submitted to NHTSA on May 16, 2018.

 

Q6: When will owners be notified?

A6: Owners will be mailed notification letters beginning in mid-December 2020.
