NHTSA Complaint #11621607 — 2016 KIA SOUL

My wife was driving the 2016 KIA Soul EV and the car just shut itself off in the middle of the intersection. She was able to turn the car off and turn it back on, but nearly caused an accident. A few months later it did it again. After getting a new software update, I told KIA About the vehicle shutting down, and they told me that if it happens again that we will need to bring it it. So we brought it in. We believe we were able to narrow down the cause to be related to regenerative breaking on a full battery. On Newer EV models, when the battery is fully recharged, regenerative breaking is disabled to prevent overcharging the battery, I dont know what they do to these kias. When we brought it in they said it needed a new battery, but I am not sure if they are going to fix the vehicle shutdown issue. I think that the BMS may be shutting the car down to prevent the vehicle from overcharging the battery when we are going down hills. I've got tired of KIA and their lies. I read information about a battery recall, and they wouldn't recall the battery and replace it with the e400 battery. They said the battery was fine. They lied to me and my wife. The battery was proven recently to be defective and they were hoping the vehicle would make it past its warranty date so they wouldn't have to replace it. We took the vehicle to KIA to replace the battery, and a couple of weeks later they were able to put a battery in it, then driving it home I was bombarded with warnings, and the vehicle power was reduced by 50%, I was afraid something would happen. The vehicle also would not charge. KIA Techs came to our house and drove it back to the dealership, and it's been there ever since. They say the vehicle needs a new BMS. I think this issue with the vehicle shutting down like this is highly dangerous and needs to be reported. It even happened once when I was in the vehicle at the middle of an intersection, which could have caused an accident! (29k miles)
