This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
1) This is the second occurrence of this issue within the past 12 months. While driving, my EV displayed various blinking lights and a -??Check EV Connection-?? message, followed by a -??12v Battery Critical-?? warning. The entire system began shutting down in the middle of the road. I managed to pull over before the car completely shut off. 2) This malfunction posed a significant safety risk to me and others. The rapid deceleration and uncertainty of an imminent shutdown almost caused an accident, either from other vehicles crashing into me or from my inability to stop in time, potentially hitting another car. I have faced this life-threatening situation twice within a year due to the same issue. 3) The problem was confirmed by my dealership less than a year ago, and my car is currently being towed back to the dealership for re-inspection of the same issue. 4) The vehicle and its components have not been inspected by the manufacturer, police, insurance representatives, or other parties for the current situation. However, the manufacturer issued a recall for this problem last year AFTER my initial report, incident, and repair. They claimed to have fixed the faulty issue or replaced the necessary parts, when my vehicle was repaired less than 12 months ago. Despite this, I am experiencing the same critical problem again. 5) During the incident, my entire panel started blinking with a -??Check EV Connection-?? message, followed by a red warning sign indicating a 12v Battery Critical Failure warning. The system then went black, and the panel continued to blink white and black consistently while parked. The car cannot be started or moved.
My vehicle was fully charged. About 1 mile after leaving my house, I received a warning message on my display (vehicle electrical system error or similar). Shortly after I received another message that power was reduced, then finally, "stop driving". I pulled into the nearest driveway and called roadside assistance. At that point, the vehicle was COMPLETELY dead. No lights or power whatsoever. I could not activate the car to shift into neutral. I had my vehicle towed to the dealership. They said it was due to a faulty ICCU and fuse. After about a week they were able to replace the ICCU, fuse and update the software.
When driving for a distance at higher speeds, power will suddenly drop to the zero point btw acceleration and regeneration. You can feel the car start to drag as the power drops. If you press hard on the accelerator to stop it from slowing, it will suddenly jump forward. This has happened now on several long trips where I am constatly fighting with the car to keep it powered and not slipping into the zero zone. When it leaps forward the lane assist will also grab control and make it difficult to control the car. The car also stops slowing consistently when I take my foot off the accelerator and will move/ jump forward more than is typical for an EV instead of slowing the way an EV should as it regenerates. This all happened twice previously on a long trip and today constantly during a three hour drive. Does not feel safe!
While driving on highway I got below messages -??Safety Functions are limited radar block warning message-?? Warning message went away after 15 minutes but then -??Stop Vehicle Check Power Supply-?? warning message appeared and vehicle slowed on highway and stopped after 2 miles. Dealer replaced ICCU and Fuse that controls high voltage (charges 12v battery from main battery).

I was driving to the dealership due to an unusual message. I was on a main street less than 2 minutes from home when an alert came on the screen that said "critical 12v system" I believe. The screen went off shortly after so I was unable to fully capture it. Within 20' the car stopped itself on the road and shut off. All systems were offline with a total power loss. I could not turn my hazards on, the wheels were locked and I was unable to move the car. I had to stand outside my car to alert oncoming traffic to avoid me. Had I been on the highway when this happened I feel it could have turned deadly quickly, and would have been far worse at night It has been confirmed that the ICCU and high voltage fuse had failed. There are many other owners online speaking of the same problem. The error prior to this reported in the car was "check electric vehicle system." No extended details available, and the online app that shows car codes said "all systems normal" and still does even though the car is entirely dead.
