Hey guys, I was having this exact same problem. I was getting power system error, battery error etc and my Vezel used to halt after a few minutes. After weeks of search and effort, I came across this amazing technician. He went through hybrid, power control unit,ECU, transmission and engine.Turns out the exhaust system of hybrid wasn't working. He replaced the exhaust system and the problem was solved completely
The solution to this problem solely depends upon the situation and the conditions. The tehnician must test thoroughly instead of looking out for preconceived notions
If you are curious about the technician who fixed my problem, here is his contact number
