NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE24-028.

try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.

On October 3, 2024, the Office of Defects Investigations (ODI) opened PE24028 to investigate alleged failures of Enel X Way's JuiceBox Level 2 residential EV chargers. The allegations were described as thermal incidents and electrical malfunctions, which could trip the circuit breakers in Juicebox owners’ homes and disrupt electric vehicle charge cycles. On October 2, 2024, Enel X Way posted on its website that Enel X Way North America would cease operations in the United States and Canada on October 11, 2024. The closure would potentially impact the charging app and supporting software. ODI sent Enel X Way an Information Request (IR) letter on October 21, 2024. Enel X Way provided an incomplete response to the IR on December 9, 2024. Enel X Way later provided a complete response to the IR on January 24, 2025. ODI reviewed Enel X Way’s IR submissions to determine whether further action is required. Based on ODI’s analysis, there was no clear trend in the cause of the failures described in customer complaints and warranty reports. Additionally, there have been no recent reports alleging safety issues. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor for any safety trends and reserves the right to take additional action if warranted by future circumstances.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
