*Median odometer reading when the problem happened, where owners gave one. One complaint can name several problem areas.
Steering
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. One instant the braking applied like I was about to hit something…

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 couldnât replicate it and could see the codes thrown. XXX picking my kids up from school sitting at a stop light and the vehicle beeped…

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.
Jul 24, 2026Service brakes
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…
Jun 2, 2026Back over prevention › Warnings
I am submitting a safety complaint regarding the driver assistance system (ProPILOT Assist) in my 2024 Infiniti QX80. The behavior of this system creates a potentially dangerous driving condition. When ProPILOT Assist is engaged, the vehicle consistently delays braking until the last possible moment, then applies sudden and aggressive braking rather than smooth deceleration. This creates a high risk of rear-end collisions, especially in moderate to heavy traffic where gradual speed adjustments are expected. In addition, the lane-keeping function appears unstable. The vehicle tends to drift or âhugâ one side of the lane instead of maintaining a centered position. At highway speeds, the…

While driving at normal speed, I suddenly heard a very loud explosion-like âboomâ coming from the roof of the vehicle. I immediately pulled over and discovered that the panoramic roof glass had shattered, leaving a large opening/hole in the glass. There was no impact from any object, no debris strike, and no visible impact point or damage consistent with road debris. Nothing hit the vehicle before or during the incident. The failure occurred suddenly and without warning, creating a serious safety concern. Shattered glass could have entered the passenger compartment and startled the driver, potentially causing loss of control. Based on the nature of the failure (loud explosive sound,…
