I am still having the same issues as the last time I reported this but new issues have occurred as well. The self driving is still disengaging with little or no warning and pulling the vehicle sharply to the left or right causing safety concerns with almost hitting another car or the center median wall on the highway. The stereo is still going black and turning the screen off. When you attempt to remedy, the buttons and screen are all frozen. When I power it off the AC goes off. The other issue is the crash warning is popping up when I'm trying to take off from a stop light, causing the wipers to start and the AC to turn off.

Error message came on with a loud beep, vehicle shut off on me while I was driving (screens went black, a/c cut off, idle message flashed across screen and the vehicle stalled out.

On numerous occasions the pro pilot feature has malfunctioned and aggressively jerked the vehicle to the left causing us to almost hit the concrete wall divider. The cruise control turns off and on numerous times when trying to change lanes. It drives dangerously close to semis when passing on the left, almost crossing into the right lane. I've taken the vehicle to the infiniti dealership and they tell me they can't duplicate it but don't do anything about it. I had my husband drive it as well and it does the same thing to him.
