From owner reports, verbatim
Malfunction: see owners manual with forward collision icon popped up. Only went away when we turned the vehicle off. Tried wiping off sensors to see if it was a sensor issue. Continued to happen. When we arrived back to [XXX] I was driving on XXX. 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. Engine came back on by itself. I was driving in my neighborhood leaving my home address. Took it to the Infiniti dealership. They couldn’t replicate it and could see the codes thrown. XXX picking my kids up from school sitting at a stop light and the vehicle beeped again when the light turned green and I started to go, idle message flashed, all screens black, a/c cut off, malfunction message came on, engine turned itself back on when the vehicle turned back on. Was told ADAS was reconfigured + software update and sent off again. XXX in the middle of an intersection loud beep, idle message, all screens black, AC cut off, malfunction message on screen again when the vehicle turned itself on again by itself. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
many times when I am using pro pilot assist it does not brake to point when it is inches of crashing into car in front, I manually have to apply brakes. in addition while being in full automatic mode (hands free mode) it turns off lane keeping assist completely where if the driver was not Able to make split second decisions it would collide with vehicle near it. there is no warning for pro pilot assist mode to be driven below or above a certain speed, Infiniti dealer advised it should not be used for bumper to bumper traffic or within city. but when even using it on highway it sticks to one side of lane and still requires hands on all times but Infiniti advertises it to drivers it is a "safe hand free option" with no warnings. just a awful accident awaiting to happen.
