Electrical arcing and thermal events, potentially leading to fires, while utilizing enel x way usa, llc's juicebox residential charger.. Closed jun 5, 2025.

NHTSA summary
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. To review the ODI reports cited in this C

Loss of motive power due to an internal wiring connector short.. Open.

NHTSA summary
On July 22, 2022, the Office of Defects Investigation (ODI) opened investigation PE22-008 regarding complaints alleging a loss of motive power condition potentially due to a transmission malfunction in Model Years 2019-2021 Chrysler Pacifica Plug-In Hybrid Electric Vehicles (PHEV). On January 17, 2023, Fiat Chrysler Automobiles (FCA) issued safety recall (NHTSA Recall 23V-010) involving 2017-2023 Model Years (MY) Pacifica Plug-In Hybrid Electric Vehicles (PHEV) produced between August 12, 2016, through January 9, 2023. The recall states that the loss of motive power condition in these vehicles is caused by an internal transmission wiring connector that may short circuit, resulting in an unexpected engine shutdown. An unexpected engine shutdown can cause a loss of drive power, increasing the risk of a crash. In discussions with FCA on Recall 23V-010, ODI confirmed the recall was related to investigation PE22-008. The remedy for 23V-010 is to update the Power Inverter module (PIM) and/or Instrument Panel Cluster (IPC) software to provide drivers a message stating “Stop Safely - Vehicle Will Shut Off Soon” followed by a chime and MIL, PRNDL blinking (on cluster and shifter knob), low SOC (State of Charge) warning and reduced power mode. The recall remedy does not replace the defective hardware that was described in Recall 23V-010, and the wiring connector short still exists on these vehicles. To date, ODI has received 132 reports for the population of vehicles subj

Ignition-off high voltage battery fire (remedy effectiveness of recall 22v-077). Open, led to recall 26V-362.

NHTSA summary
On February 11, 2022, Fiat Chrysler Automobiles (FCA) issued a safety recall (NHTSA Recall 22V-077) on all 2017-2018 Pacifica Plug-In Hybrid Electric Vehicles (PHEV) produced between August 12, 2016 through August 7, 2018. The recall addresses ignition “OFF’ fires that originate at the high voltage (HV) battery pack assembly. An ignition ‘OFF’ vehicle fire can result in an increased risk of occupant injury, injury to persons outside the vehicle, and property damage, with little to no warning. At the time of the recall filing the root cause of the vehicle fires was unknown and under investigation by FCA and suppliers. A software remedy designed to improve thermal event detectability by monitoring battery diagnostics is currently being installed on subject vehicles as an interim remedy. As of November 23, 2023, the root cause of the battery failure is unknown. From December 2022 through December 2023, NHTSA has received four consumer complaints (VOQs) alleging vehicle thermal events involving recalled 2017 and 2018 Chrysler Pacifica PHEVs. Additional information collected from complainants confirmed a thermal event originating near or at the HV battery pack after the Recall 22V077 remedy had been applied to the vehicle. Follow up meetings with FCA and suppliers in November and December 2023 to discuss the ongoing root cause investigation and post-recall remedy incidents indicated a recent increase in HV battery thermal events. Furthermore, a review of NHTSA complaint da

Should you keep driving it?

This page can't tell you that. 1 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
