The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into potential fire hazards associated with Enel X Way USA’s JuiceBox Level 2 residential EV chargers. Prompted by several complaints received by the Office of Defects Investigation (ODI), this evaluation aims to determine the extent and safety implications of electrical arcing and thermal incidents reported by users of these chargers. This probe focuses on the potential for fire risks arising from electrical malfunctions and the company’s recent operational shutdown announcement.

Summary of Complaints Filed with ODI

ODI has received six Vehicle Owner Questionnaires (VOQs) concerning alleged incidents involving the JuiceBox Level 2 charger. These complaints raise serious concerns regarding potential fire hazards that may arise while charging electric vehicles at home. The following highlights from the complaints showcase the range of issues reported:

1. Total Home Loss Due to Explosion: One complaint involves a significant incident where a vehicle owner claims that charging their EV with a JuiceBox led to an explosion in their garage. This catastrophic event resulted in a fire that destroyed the home entirely.
2. Car Fire in Driveway: Another complaint describes an incident where a vehicle caught fire in the driveway while connected to a JuiceBox charger. The details of this incident underscore concerns about charger reliability and the potential for dangerous outcomes.
3. Electrical Malfunctions and Circuit Breaker Issues: Four additional complaints describe issues with electrical malfunctions that caused circuit breakers to trip and charging cycles to be disrupted. These electrical disruptions may indicate underlying issues with the chargers’ compatibility or durability under varying conditions.

Enel X Way’s Operational Shutdown and Potential Impact on User Safety

In an unexpected development, Enel X Way North America announced its intention to cease operations in the United States and Canada by October 11, 2024. A notification was sent to JuiceBox owners on October 2, 2024, which was also posted on the company’s website. This cessation of operations could potentially impact several aspects of the product’s performance and user experience:

• Software and App Support: As Enel X Way discontinues its North American presence, questions remain about the continuity of the charging app and supporting software. Given that many smart chargers rely on connected software for updates and safety monitoring, the lack of support could leave users with outdated or unsupported technology.
• Customer Support and Warranty Services: The cessation of operations may also impact the company’s ability to provide customer support, particularly regarding ongoing technical issues, troubleshooting, or warranty claims for JuiceBox chargers.

ODI Preliminary Evaluation and Safety Scope

In response to these serious complaints, ODI has opened a Preliminary Evaluation to examine the safety and reliability of JuiceBox Level 2 chargers. The purpose of this evaluation is to assess the scope, frequency, and potential hazards associated with these products. The investigation seeks to determine:

• Risk of Fire and Explosion: By evaluating complaints of thermal events, such as the explosion in the garage and the driveway car fire, ODI aims to understand the risk factors and whether the JuiceBox charger’s design or operational faults are contributing factors.
• Electrical Stability and Safety Consequences: ODI’s analysis will also delve into the frequency of electrical malfunctions and whether these events pose a risk of property damage, personal injury, or loss of life.
• Impact of Software and Operational Changes: With the discontinuation of Enel X Way North America’s operations, ODI is concerned about the potential safety implications arising from the lack of app and software support. The investigation will evaluate if and how this operational change might exacerbate existing safety concerns or introduce new risks.

Affected Vehicles and Part Numbers

The ODI investigation includes a review of incidents involving various EV models that utilized the JuiceBox Level 2 charger. The vehicles associated with these complaints include:

• Chevrolet Bolt EV (2018)
• Chrysler Pacifica Hybrid (2018)
• Hyundai Ioniq 5 (2022)
• Hyundai Ioniq 6 (2023)

Additionally, the specific product part under scrutiny is the Enel X JuiceBox Level 2 Charger.

Steps for Consumers and Further Information

For EV owners who currently use the JuiceBox Level 2 charger, awareness of this investigation is crucial. Users are encouraged to follow any guidance issued by the NHTSA and consider consulting with licensed electricians to ensure proper installation and safe operation of their EV chargers.
