   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.

   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.

   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 “hug” one side of the lane instead of maintaining a centered position. At highway speeds, the system makes abrupt and overly aggressive steering corrections, even when the vehicle is already within lane boundaries and at a safe following distance. These sudden inputs feel unnatural and reduce driver confidence, requiring constant manual correction. Overall, the system behavior is unpredictable and does not align with reasonable expectations for a driver assistance feature. Instead of enhancing safety, it introduces unnecessary risk by combining delayed braking with aggressive steering inputs. This issue occurs under normal driving conditions on clearly marked roads and does not appear to be an isolated event. Given the size and weight of the QX80, these system responses could lead to serious accidents if not addressed. I request that this issue be investigated, as it presents a significant safety concern for drivers and others on the road.

   While driving at normal speed, I suddenly heard a very loud explosion-like “boom” 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, sudden collapse, no impact evidence), this appears to be a spontaneous glass failure / manufacturing defect of the panoramic roof. This incident raises concerns about the safety and structural integrity of panoramic roof glass on this vehicle model.
