Q&A

 

Q1: What is the issue?

A1: The subject vehicles are equipped with battery cells manufactured in the LG Energy Solutions China (Nanjing) plant in which the Anode (Negative) tab can be folded. A folded Anode tab in the battery cell could allow the Lithium plating on the Anode tab to contact the Cathode resulting in an electrical short.

 

Q2: What are the affected vehicles?

A2: The subject vehicles include:

  • Approximately 4,694 model year 2019-2020 HyundaieBay logo Kona Electric vehicles produced from August 28, 2018 through March 2, 2020.
  • Approximately 2 model year 2020 HyundaieBay logo Ioniq Electric vehicles produced from November 8, 2019 through November 11, 2019.

 

Q3: What is the safety concern?

A3: An electrical short internally within battery cell(s) increases the risk of a vehicle fire while parked, charging and/or driving.

 

Q4: Have there been any accidents or injuries?

A4: To date, HyundaieBay logo is not aware of any fires or injuries/fatalities in the U.S. attributable to this condition.

 

Q5: What will be done during the recall service at the dealer when the remedy is available?

A5: Remedy is currently available for 19MY and 20MY Kona EV vehicles. The battery system assembly (BSA) will be inspected, and if applicable, may need to be replaced and/or the Battery Management System (BMS) may also need to be updated.

 

Q6: When will owners be notified?

A6: NHTSA has posted this recall. Owners were mailed interim notification letters in April 2021 regarding a remedy not yet available. 19MY owners began receiving remedy available notification beginning in late June 2021 as battery supply became available for their vehicle. 20MY owners previously received a remedy not yet available letter.

With the re-launch of recall 200 TSB including 20MY vehicles, 19MY and 20MY owners will both receive remedy available letters in the coming weeks.

 

Q7: Should customers park these vehicles outside until the recall repair is completed?

A7: Out of an abundance of caution, owners of these vehicles should park them outside until the recall repair is completed. If needed, the customer will be provided a rental vehicle. If battery SOC has been set to 80% (Service Campaign P29) the vehicle can be safely charged and operated, including parking inside.  

 

Q8: Why should customers park their vehicles outdoors?

A8: Customer safety is our top priority. After further review, it was determined that out of an abundance of caution customers should park the vehicles outside until the recall is completed.

 

Q9: If a customer has had the P29 completed, is the vehicle safe to charge and operate? A9: Yes. If the P29 has been completed the vehicle can be safely charged and operated.   

 


Description: Some vehicles may experience a short circuit inside the high voltage battery cell. An electrical short within battery cell(s) increases the risk of a vehicle fire while parked, charging and/or driving. The Battery System Assembly may need to be replaced and/or the Battery Management System (BMS) software may need to be updated.

RECALL 200 ATTACHMENT A

CHRONOLOGY OF EVENTS LEADING UP TO DEFECT DECISION

 

  • March 2019 – August 2019 

HMC received three reports of Kona Electric vehicles catching fire while parked in the Korean market. All vehicles involved were reportedly parked with full state-of-charge in the vehicle’s Li-ion battery. HMC conducted a search globally and found two similar incidents in Canada, and one incident in Europe. HMC reviewed and investigated these incidents with the Korea Automobile Testing & Research Institute (“KATRI”) and Transport Canada (“TC”) respectively.

 

  • September 2019 to March 2020 

HMC and KATRI continued to jointly investigate known fire cases through regular discussions on KATRI’s opened defect investigation. In March 2020, a service campaign was launched globally to upgrade the BMS software for automated early detection of abnormalities in the Li-ion battery state while the vehicle is parked. This software update was developed jointly with the Tier 2 battery cell supplier, LG Chemical, as a fail-safe “level-up” countermeasure. HMC began collecting and analyzing Li-ion batteries replaced under the campaign to continue their investigation.

 

  • April 2020 – October 2020

HMC received an additional seven reports globally of fires on parked Kona Electric vehicles. Six of these incidents occurred in Korea while one occurred in Europe. HMC continued joint review and study of these incidents with KATRI. HyundaieBay logo continued its investigation by studying the effects of electrical shorting in the Liion battery. While unsuccessful in duplicating the actual fire condition, HMC confirmed that the BMS software update associated with the previous service campaign could detect the early onset of an internal short, illuminate a warning light, and limit the vehicle’s power until the diagnostic code is cleared.

 

  • October 2020

HMC informed HMA of their findings on October 7, 2020. HMA convened its NASDA on October 8, 2020 and decided to conduct a safety recall campaign to repair all potentially affected vehicles in the U.S.

 

On October 17, 2020, a Kona EV vehicle with the updated software caught fire in Korea at full state of charge.  The investigation into the fire was unable to determine a root cause due to the severe damage to the Battery System Assembly (BSA).

 

  • January – February 2021

HyundaieBay logo became aware of a Kona EV vehicle with the updated BMS software that caught fire while at full state of charge. The investigation into the cause of the fire revealed an internal short within the battery cells. Continuing its investigation into the cause of the internal short circuit, HMC determined that a folded Anode tab in the battery cell could result in Lithium plating on the Anode tab to contact and short circuit to the Cathode. HMC notified HMA of their findings.

 

Based on the information received, on February 23, 2021, HMA convened its North American Safety Decision Authority and decided to conduct a safety recall campaign to repair all potentially affected vehicles in the Canadian and U.S. markets.

 

To date, HyundaieBay logo is unaware of any fires/injuries in the U.S. market related to this condition.
