FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

ELECTRICAL SYSTEM
Summary: Recurring weak/no-start condition due to low battery voltage despite new battery replacement. Charging system (VVCS) fails to adequately maintain battery charge on normal driving patterns. -Purchased certified pre-owned vehicle Dec 2024. -Began experiencing weak battery (weak or no starts) approximately Jul 2025. Jump started and charged for a few months, as issue was intermittent. -Symptoms got worse, brought vehicle to dealer Nov 2025. Battery tested bad and replaced by dealer. -Experienced weak battery again June 2026. Voltage readings: 12.16V resting, drops to ~12V while driving after initial 15V spike. Charged battery with battery charger. -Took vehicle to dealer again 6/29/26. Dealer confirmed smart charging behavior, no parasitic draw, no codes, good battery (had been recently charged), good alternator. Dealer suggested that smart charging system does not align with driving behavior and recommended battery maintainer as workaround. Safety impact: Weak starting creates potential stranding or safety risk (especially in traffic or emergencies).

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

VISIBILITY:GLASS, SIDE/REAR
Back window shattered for no reason. Vehicle parked on property and was fine when we came home last night in another vehicle and parked behind it. Online found out this has been happening where the back window spontaneous combustion for no reason. Checked property surveillance cameras and confirmed no one was on property at all. Highly concerned as third-row seating is so close to back window a child could be seriously injured. Glass was found behind 2 ND row. Manufacturer not helpful as they want me to drive with broken glass to dealership on highway to determine if they might cover it.

WHEELS
I experienced severe wheel instability on 3/29/2026 at around 630pm on I74 West while traveling on the highway at high speed. I was forced to perform emergency maneuvers to avoid a catastrophic collision, resulted in a terrifying near-miss incident that required an emergency tow to safety. Upon inspection, it was confirmed that the lug nuts on the left rear wheel were not properly torqued and were dangerously loose as outlined by the tow report below :-----Please see the following service report regarding PO 3166 for a 2025 Infiniti QX80. When we arrived on scene, the customer stated that the vehicle made a sudden jerk and veered unexpectedly while being driven. Before touching or loading the vehicle, we took photos and observed that the left rear wheel appeared to be close to coming off the vehicle. Upon further examination, we found that 3 of the 5 lug nuts had broken off completely. The remaining 2 lug nuts were still in place, but were barely holding.I advised the customer that the safest course of action was to jack the vehicle up and tighten the 2 remaining lug nuts as much as possible in order to reduce the risk of the wheel falling off during loading, unloading, or transport. This was done strictly to help avoid additional body or vehicle damage---: Most critically, my [XXX] child was in the vehicle during this life-threatening event placing my family in immediate catastrophic near miss dangerous event.

BACK OVER PREVENTION: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

FORWARD COLLISION AVOIDANCE: WARNINGS, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
What component or system failed or malfunctioned, and is it available for inspection upon request? Two components have failed: the infotainment/Apple CarPlay system, including the USB-C connectivity port, and the front collision detection/crash sensor system. The entire A/V unit was replaced on August 1, 2025, yet the infotainment defect persisted. Both systems are currently installed in my vehicle and are available for inspection upon request. How was your safety or the safety of others put at risk? The front collision detection system malfunction directly compromises my ability to rely on the vehicle's built-in safety features to prevent or mitigate crashes. Additionally, the infotainment screen has frozen and reset while the vehicle was in motion. I have also been locked out of my vehicle twice while the engine was running, which created a dangerous situation. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. On July 25, 2025, a technician at Georgetown Infiniti attempted and failed to connect their own phone to the CarPlay system, confirming the defect was in the vehicle and not my personal device. The collision system malfunction has been documented across multiple service visits at both Georgetown Infiniti and Grubbs Infiniti. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle has been inspected and serviced by authorized Infiniti dealerships, specifically Grubbs Infiniti and Georgetown Infiniti, both of which are manufacturer-authorized service centers. Most recently addressed 2/4/20226. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The infotainment screen displayed warning messages, froze, and reset while driving. The front collision system displayed malfunction warnings on the dashboard.

SEAT BELTS
The contact owns a 2025 Infiniti QX80. The contact stated that the middle seat belt receiver failed to function as intended. Upon inspection, the contact became aware that when the third-row seat was folded under, the seat belt receiver was crushed. No warning lights were illuminated. The vehicle was taken to the dealer, where it was confirmed that the seat belt receiver was damaged by the third-row seat. The vehicle remained at the dealer pending the repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.

STRUCTURE:BODY
While driving my Infiniti QX80, 2025 model, the driver's side mirror is constantly shaking and vibrating, especially on uneven roads or at speeds over 40–50 mph. The vibration blurs the mirror, making it impossible to see clearly and posing a safety risk. I brought this to the dealer, but they could not resolve the issue. They replaced the mirror, yet it did not help and actually made the vibration worse. Now they claim this is "normal" and that nothing can be done. However, the vibration is constant and unacceptable for safe driving. I request further investigation and resolution.

ENGINE, VEHICLE SPEED CONTROL
I have been saying that my vehicle is a safety hazard since April 2022. I have had it to the dealer 4x since then in addition to opening up several cases with Inifiniti Customer Service, but nobody has been able to protect my family and I and remedy the situation. At times the vehicle will not accelerate even when I push the gas all the way down. Then it will kick in and surge forward. I also have told them that at times it feels as if someone has rear ended me. There is a recall out there for cars manufactured through April 2020, but mine was manufactured in September 2020. Infiniti's recall is #R21A3 and the NHTSA ID is 21V373. I have experienced the same exact symptoms as those covered under this recall. Now Inifiniti is telling me that my transmission needs to be replaced as a result of metal shavings in the oil. Again, this could all have been caused by this fuel pump issue which was on their radar in 2021 and 2022 when I brought my car in the first time. Infiniti has failed to help me in every step of the way beginning with their Service Tech not fixing the issue back in 2022 through 2024 when I have consistently expressed my concerns while the car was still under warranty.

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
This is a 2021 Vehicle, and beginning in April of 2022, I have been telling my dealer that there is something wrong, but they haven't been able to fix it. When I am driving, there are times when the car will fail to accelerate. Also at times it feels like I have been rear ended and the car lurches. I have said this is a safety issue and neither the dealer nor Inifiniti Customer Consumer Affairs have taken this seriously and remedied the situation. They all say there is nothing they can do. I have taken it to the dealer 6 times and opened up a case with Infiniti back in 2024 with no resolution.

UNKNOWN OR OTHER
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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
Camera monitoring system or rear visibility system. The rearview/backup camera has intermittently malfunctioned in my QX80 numerous times since I purchased the car in February 2024, including (1) displaying a frozen image from the backup camera when putting the car in reverse which stayed frozen (for example, did show a car driving directly behind me which I almost hit) and displayed the frozen image to the driver the entire time driving the car, including at highway speeds, and which could not be manually removed from view (including by pressing the camera button); and (2) the backup camera not turning on at all when the QX80 is put in reverse, not could the backup camera be turned on manually by pushing the camera button. I attached some photos of the frozen rearview/backup camera which remained displayed to the driver the entire time driving the car, including while traveling on the interstate at highway speeds (65 mph) when the photos were taken attached below. The date below is the date of the photo, however backup camera malfunctions has occurred numerous times and dates. I also have numerous videos of the malfunctions described herein that I can also share.

AIR BAGS
A lady driving a Honda Fit pulled out in front of my wife while she was driving her Infinity QX80. My wife was driving about 40-45 MPH at the time of the crash. The driver at fault in the Honda Fit I noticed all air bags deployed. My wife's QX80 had none of the air bags deployed. The officers at the scene were shocked to see the amount of damage to my wife's QX80 while not triggering the air bags to be deployed. One in particular told us to make sure we reported this to the insurance company.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER, SUSPENSION
New QX80 should be taken off the road. The Infotainment system is the central computer system to the car. Countless times where the system reboots WHILE DRIVING yielding electronics cluster (Speed control, Heads up Display, etc) blacked out. Upon "reboot", the stereo system is blaring loud, without ability to turn down volume, creating a dangerous driving environment. Only resolution, to date, is to press and hold for 10-15 seconds the powerbutton to shutoff. Having to do this while driving is dangerous. Other isntances where the car pneumatic suspension system - connected to said infotainment system - faults and creates the car to go up/down while driving. This is similar to a friend who has the same exact car, who's having the same exact issues. There is no resolution. This car NEEDS TO BE TAKEN OFF THE ROAD UNTIL INFINITI CAN PROVE STABLE COMPUTER FUNCTIONALITY. IT WILL CREATE ACCIDENTS/DEATH. This has happened numerous times. Photo is from most recent after driving "blind" on the cluster back to our driveway to take a picture.
