Power Outlet May Cause Charging Cable to Overheat

An overheated outlet or charging cable can increase the risk of a fire.

 

NHTSA Campaign Number: 23V842

Manufacturer VolkswageneBay Group of America, Inc.

Components ELECTRICAL SYSTEM

Potential Number of Units Affected 93,196

 

Summary

VolkswageneBay Group of America, Inc. (AudieBay) is recalling certain 2022-2024 RS e-tron GT, e-tron GT, Q4 e-tron Sportback, Q4 e-tron, 2020-2021 AudieBay A8, 2019-2024 e-tron Quattro, 2020-2024 e-tron Sportback Quattro, Q5, and 2021-2022 A7 vehicles. When using the industrial 220V/240V plug at the 100% charge setting, some home power outlets may be incapable of handling the electrical current required to utilize the compact charging system, causing the outlet or charging cable to overheat.

 

Remedy

Owners are advised not to use the 220V/240V compact/portable charging cable and only use the 110V home charging cable or public charging stations. Dealers will supply a new 220V/240V compact/portable charging cable with an incorporated temperature sensor, free of charge. Interim owner notification letters explaining the safety risk are expected to be mailed February 9, 2024. A second notice will be sent once remedy parts become available, anticipated mid-2024. Owners may contact AudieBay customer service at 1-800-253-2834. AudieBay’s numbers for this recall are 93U6 and 93U8.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

Chronology of Defect

September 2020: AudieBay became aware of cases where melting/overheating occurred at the industrial socket (NEMA 14-50) when charging with the industrial 220V/240V plug with 40 amperes.

October 2020 – December 2021: AudieBay requested parts from the field and analyzed the patterns and surrounding circumstances of customer charging behavior. All analyzed cases did not show any issues with the vehicle and the delivered charging equipment itself. The root cause always appeared to be household power outlets and/or household wiring/circuit breakers incapable of handling the required electrical current.

All investigations showed that the power outlets and/or wiring may be incapable of handling the required electrical current, if the proper electrical requirements are not met. In this case use of the compact charging system with improper or overburdened 220V power outlets and wiring may, in certain circumstances, lead to a risk of overheating of the home infrastructure.

Therefore, AudieBay decided to implement a service campaign where customers were sent detailed instructions and asked to bring the charging equipment to an AudieBay dealer to change the setting on the charging system control unit to 50% power level for the industrial plug and attach a warning label to the control unit of the AudieBay compact charging system. With these measures, it is still possible to charge at a charging current of 100% by pressing the button (100%) on the control unit if customers have assured that their home power supply meets all the requirements for safely charging the high-voltage battery at a current rating of 40 amperes.

February 2022 – November 2023: Field monitoring continued and AudieBay continued to receive reports of overheated and melted sockets.

December 6, 2023: A re-evaluation based on the field situation determined that a misuse still cannot be ruled out even with the additional warning instructions and the previous service campaign. Out of an abundance of caution, AudieBay determined it would supersede its existing service campaign and conduct a safety recall to replace the affected charging cables by a new charging cable with incorporated temperature sensors. In unsold vehicles the industrial charging cable will be removed from the charging equipment before delivery.

AudieBay is currently aware of 615 claims, dating from 08/05/2020 – 12/05/2023, and no fires, crashes or injuries potentially related to this issue.
