This has happened several time in the city crossing an intersection usually at slow speed braking and turning and all the sudden I lose everything. No steering electrical and braking. The park assist will sometimes start going off like crazy just before it happens, but not all the time. Put in park and open the door it comes back on. Then says roll down drivers side window and then back up. At on time I did have it happen on the highway. I was getting ready to pass and giving it gas and everything shut down for a split second and then took off again. This problem is going to get someone killed.
