Defect investigations
Electrical arcing and thermal events, potentially leading to fires, while utilizing Enel X Way USA, LLC's JuiceBox residential charger.
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 the federal safety agency 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 2023 Hyundai Ioniq 6 owners say
Most recent owner complaints, unedited.
The shift-by-wire system failed while the vehicle was being parked. The vehicle would not shift out of Drive; repeated attempts to engage Park resulted in Neutral only, with a "PARK malfunction. Engage parking brake when parking vehicle." warning displayed in the instrument cluster. Because this vehicle requires Park to be engaged before it can be powered off, the vehicle also could not be turned off. I was trapped with an energized vehicle that could not be secured in Park or shut down for approximately 30 minutes. A red 12-volt battery warning lamp was illuminated in the instrument cluster during the event (photo attached showing the malfunction message, Neutral gear state, and battery warning lamp). I secured the vehicle using the electronic parking brake. Safety risk: a vehicle that cannot engage Park or power off risks rollaway and leaves the driver unable to safely exit and secure the vehicle, particularly on a grade or in traffic. This is the second occurrence of a shift-to-park failure on this vehicle. The vehicle was previously taken to an authorized dealer for the same symptom; the dealer cleared diagnostic codes without repair and the problem recurred. The vehicle is scheduled for further dealer diagnosis and is available for inspection upon request. The ICCU recall remedy (Recall 272) was previously completed on this vehicle per the manufacturer's campaign records.
While driving on the highway, there was a complete loss of power and steering. I was able to navigate to the side of the road. The vehicle would not start on multiple occasions, and no warning lights illuminated. The vehicle was taken to the dealer, where it was stated that the issue could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the issue. The approximate failure mileage was 18,000.
In November of 2025 the vehicle displayed a "Check Eletrical System" error message. Shortly thereafter the vehicle decelerated to under 10mph as we were turning into traffic. We were able to drive it home (less than 1mi away) and then called the Dealership. The car was then towed to the dealer (but needed a jump as the 12v battery had drained). The dealer diagnosed a failure of the ICCU and replaced it. The vehicle was in the shop for approximately 2 weeks. More recently, on May 3rd of 2026, the vehicle experienced a complete deceleration as it was traveling through an intersection. No error lights or warning messages were displayed. I was only able to partially clear the intersection before the vehicle came to a complete stop. At this time the vehicle would not allow itself to be put into neutral so I could not push it out of the intersection. After approximately 5min of attempting to move the vehicle, it once again began responding to accelerator requests and I was able to drive it home. It is now with the dealer and I await their response.
I was pulling into a parking spot and my vehicle suddenly lurch forward, and I had to slam on the brakes quickly, scraping the front of the curb. I checked there was no warning lights. I checked the floor mat, and this was not impeding the accelerator pedal I am certainly I did not accidentally hit the accelerator instead of the brake.
On March 19, 2026 my Hyundai Ioniq 6 broke. It was clearly the ICCU problem. The car went into turtle mode with a maximum speed of 22 miles an hour and told me to get to a safe area , stop the car and have it brought in. It was brought to my local Hyundai dealer and a few days later they confirmed it was the ICCU problem. This is a safety issue. Fortunately I was 1 mile from my house and did not get stranded. Hyundai has had four years to fix the problem and obviously they have not done so. The car was a 2023 with about 23,000 miles on it.
I was driving and my electrical warning light came on again for the second time in a year. I was told it was the iccu last year and they said it was fixed and wouldnt have a problem again. I had to rent a car for almost two months. The same problem again with the iccu happened about a month ago and they still have my car. In a another gas rental car.
The fuel door/charge door would not open. Conditions were such that I was safe and had sufficient range without charging, but were I farther from home this could have left me stranded. The problem has not been confirmed by a dealer, other service center, manufacturer, police, or insurance representative, though a friend was not able to open it either/confirmed the issue was not "user error". There were no warnings. The incident occurred after rain in the prior evening, followed by below freezing temperatures. The fuel/plug door opened in the afternoon when temperatures were warmer.
I leased a 2023 Ioniq 6 electric car on September 2023. Since leasing the vehicle, the vehicle has been towed four times for the same problem, the parking brake malfunctions rendering the vehicle unusable. I have multiple photos and videos documenting this. This has happened either after parking the vehicle and attempting to turn it off, or after turning on the car after being parked. The first three times this happened the vehicle remained in neutral and would not change into any other gear. The car would not turn off or lock. The last time it happened again the car stayed in neutral and would not change gears, but I was still able to turn it off and lock it. Below is a summary of all the times the car was towed and how many days it was in the dealer. 1.December 12, 2025 (towed to dealership #1) to December 19, 2025: 8 days, no action taken, unable to find the cause of the problem 2.December 20, 2025 (towed to dealership #1) to December 29, 2025: 10 days, no action taken, unable to find the cause of the problem. Note the car failed again the day after it was returned to me on December 19. 3.January 2, 2026 (towed to dealership #2) to January 13, 2026: 12 days. Changed the 12V battery and replaced the VCU, vehicle control unit as an educated guess based on conversations with the Hyundai engineering team as the initial diagnostic scan failed to pinpoint the problem. 4.March 12, 2026 (towed to dealership #2). As of tMarch 15, 2026 the car is in the dealership for repairs for the same problem. Since this problem is likely related to the electric car’s electronics, it has been both challenging to diagnose, and extremely unpredictable and dangerous when it happens without any previous actionable warnings. The fact that the parking brake malfunctions and cannot engage, and that in addition the car gets stuck in neutral, is an extremely serious safety concern that could result in an accident, injury or death.
The check electric vehicle system error message showed up on my dashboard, meaning the iccu has failed
