Randomly all electronics shut down engine stalls and lane assists wont let me turn wheel while driving in road. Normally at slow speeds. Get random warning lights that go away after seconds. When I activate a window switch all the electronics turn off and on. This happens randomly. No codes have been left to pull up when trying to solve issue. Twice with children in the car in traffic that we have almost got in a wreck due to these random issues.
