FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: WARNING, LANE DEPARTURE: BLIND SPOT DETECTION
As captured in images uploaded herein, the subject Infinit QX80's advanced safety system suite malfunctioned completely and without warning at 948 miles. The vehicle dash captures the numerous systems that simultaneously fail including: collision avoidance, steering assistance, lane assistance, blind spot monitoring - and all systems that rely on the advanced camera suite. Importantly, the first failure happened at highway speed without warning and resulted in the steering assist failing on a banked curve and directly placed a family of six within inches of a high-speed collision with an 18-wheeler. This same, intermittent recuring malfunction has happened TEN additonal times including and after SEVEN authorized dealership repair attempts. The dealer has replaced cameras, the entire dash, rebooted the entire software system, and then undertook a "hail mary" to hard reset the car by unhooking the battery and rebooting the vehicles operating system. The vehicle continues to malfunction. The dealership cannot replicate the code because the car does not recognize that there has been an error. The failure to store the failure codes means the dash resets every time the car is shut off and restarted. That makes diagnosis nearly impossible and the dealer just keeps replacing random parts hoping to luck out and fix the underlying electrical, software, wiring, or camera issue. Nissan has refused to acknowledge this serious safety issue and will not repurchase the vehicle. We have four daughters under 12 years old and are forced to keep driving this unsafe car until someone helps or something tragic happens. PLEASE HELP US! I can provide the repair orders from the dealership.

STEERING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
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 but no cars were in front of me at the light. The car also turned on like it was in auxiliary mode after I got out and walked around to the passenger door to get my child out. These are causing lots of stress and numerous trips to the dealership to attempt to remedy. My vehicle has been at the dealership since Sept 29, 2026 making this the 3rd time and over a month total of not having access to it.

STRUCTURE:BODY
National Highway Traffic Safety Administration (NHTSA) U.S. Department of Transportation 1200 New Jersey Avenue SE West Department, Washington, DC 20590 SUBJECT: SAFETY COMPLAINT – STRUCTURAL PAINT DELAMINATION AND DEBRIS HAZARD • Vehicle: 2016 Infiniti QX80 • Paint Color: Pearl White (Paint Code: QAA) • Affected Area: Roof, hood, and upper body panels To Whom It May Concern, I am filing a formal safety complaint regarding a severe manufacturing defect on my 2016 Infiniti QX80 featuring the factory Pearl White (QAA) paint finish. The factory paint and primer have experienced a complete adhesion failure, causing the paint to shear off in massive, thick chunks down to the bare, unprimed sheet metal. This issue is not a cosmetic concern; it is an active highway safety hazard. The paint layers are delaminating at highway speeds, causing hard, sharp chunks of paint debris to violently fly off my vehicle’s roof. This poses an immediate distraction and danger to trailing motorists who are forced to swerve or suffer windshield impacts from the flying debris. Furthermore, the rapid deterioration of the protective coating risks structural corrosion of the roof panel over time. This is a well-documented, widespread manufacturing defect concerning Nissan/Infiniti’s factory white paint formulations, where an improper chemical bond between the primer and the metal substrate causes a total delamination failure. I request that the NHTSA review this defect for a formal safety investigation, as the debris shedding from these large SUVs at high speeds presents an unaddressed risk to public roadway safety. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
I am reporting a potential fuel/fire safety defect involving TWO brand-new 2027 Infiniti QX80s. My first QX80 developed a strong raw-gasoline odor after driving/shutdown, especially when parked in my residential garage. I repeatedly reported this to Infiniti. Various explanations were given, including Arizona heat and gasoline formulation. The dealer ultimately exchanged the vehicle. The replacement 2027 QX80 developed substantially the SAME gasoline odor after only about 12 miles from the dealership to my home. I returned it for evaluation. On XXX, Infiniti on Camelback inspected the replacement vehicle. This is no longer based solely on my observation. Their final repair order documents my complaint of “fuel smell coming from the rear driver side wheel area” and, importantly, states their inspector “had a fuel smell at the time of check in and in the shop while sitting in the shop.” The dealer found no codes or visible fuel leak. Therefore, an Infiniti dealer independently detected and documented the fuel odor. Afterward, I spoke with Service Director [XXX]. He told me he had discussed this same issue/condition with an Infiniti field engineer and that Infiniti was aware of it. My understanding was that he was not aware of a specific repair, corrective procedure, or available fix at this time. I am extremely concerned because the same condition occurred in TWO new QX80s, the dealer confirmed the fuel odor, Infiniti field engineering is reportedly aware, yet no cause or fix has been provided. No diagnostic code or visible liquid leak explains why gasoline vapor/odor is present. My concern is fire risk and gasoline-vapor exposure, particularly when parked in an attached residential garage. I request NHTSA investigate the QX80 fuel/EVAP system and similar complaints. Vehicle and documentation are available for inspection. Infiniti Case #XXX. VIN: [XXX].

FUEL/PROPULSION SYSTEM
I purchased a new 2027 Infiniti QX80 Autograph, VIN [XXX], from Infiniti of [XXX] on XXX with approximately 10 miles. On XXX, the day after purchase, I contacted the dealer because I noticed a strong raw gasoline/fuel-vapor odor after driving the vehicle, shutting it off, and parking it inside my garage. The dealer initially advised me to wait 4-5 days because the vehicle was new and suggested the odor might resolve. The odor persisted. The vehicle had approximately 300 miles when the problem continued. I returned to the dealer and was advised that the fuel tank and/or EVAP canister might need replacement and that parts could take weeks, with no definite repair timeline. The suspected affected system is the fuel/EVAP system, including the fuel tank, EVAP canister, vapor-control system, fuel-system venting, or related components. The exact cause is UNKNOWN. The vehicle was available for dealer inspection. I am concerned because a strong raw gasoline/fuel-vapor odor in an enclosed residential garage may indicate abnormal fuel-vapor release and could create a potential fire hazard and expose occupants to fuel vapors. No warning lights or dashboard messages appeared. The primary symptom was the strong gasoline odor after normal driving and shutdown. Because of this unresolved safety concern, the dealer ultimately replaced this vehicle with another new 2027 QX80. The replacement vehicle later developed the same strong gasoline/fuel-vapor odor. I am concerned this may represent a broader fuel/EVAP system defect rather than an isolated problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
I am filing this complaint regarding my replacement 2027 Infiniti QX80 Autograph, VIN [XXX]. My original new 2027 QX80 developed a strong raw gasoline/fuel-vapor odor shortly after purchase. I reported it to Infiniti of Scottsdale on XXX, one day after purchase. The dealer initially advised me to wait 4-5 days because the vehicle was new. The odor persisted, and the dealer later advised that the fuel tank and/or EVAP canister might need replacement. I filed NHTSA Case No. XXXfor that first vehicle. Infiniti of Scottsdale provided this replacement QX80 on XXX. Within one day, the replacement vehicle developed the same strong raw gasoline/fuel-vapor odor, especially after driving, shutting the vehicle off, and parking it inside my garage. I returned the replacement vehicle to the dealer on XXX because of the same condition. The suspected affected system is the fuel/EVAP system, including the fuel tank, EVAP canister, vapor-control system, or related components. The exact cause in the replacement vehicle is UNKNOWN. The vehicle is available for inspection through the dealership. I am concerned that strong gasoline vapors in an enclosed garage could present a potential fire hazard and expose occupants to fuel vapors. No warning lights or dashboard messages appeared. The primary symptom was the strong raw gasoline/fuel-vapor odor. The same condition occurring in two separate brand-new 2027 QX80 vehicles raises concern that this may be a broader fuel/EVAP system safety defect rather than an isolated problem.

FUEL/PROPULSION SYSTEM
I apologize in advance if I’m not using the correct form to find out this information, hopefully if this does not reach correct person you can get to correct person for me. There has been a constant gas smell coming from gas tank area since we purchased vehicle in 2/2026. I thought it was just fumes from adding fuel but have since (while reaching in to retrieve grandbaby from back seat, I noticed a strong smell reaching towards driver door and a slight gas smell reaching inside vehicle. We have not been able to locate a gas leak anywhere just the strong gas smell. I’m trying to find out if this is a common occurrence for this vehicle or if there is a recall on it for this problem. Also if there has been a recall is there a way I can find out if the recall has been repaired. Thanks for any information you can provide.

I've had 2 incidents where my vehicle has stopped and not restarting. I took it to the dealership, and they stated I needed a starter. I see there are several complaints regarding this issue with the model QX80. Ive also had to get 2 new batteries with 1 year. Please look into the issues. I went to the dealership on 8/18/2026 they said my vehicle didn't start . My vehicle did start and I took it to another repair shop and save over 1300.00 To say my car wouldn't start and it did . I'm glad it did so I didn't have to pay so much for and it was done in less than 1hr

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.

UNKNOWN OR OTHER
Subject: Request for Safety Defect Investigation and Recall – 2018 INFINITI QX80 Infotainment/Navigation Screen To Whom It May Concern: I am writing to formally request an investigation into a serious and recurring problem with the infotainment/navigation screen in my 2018 INFINITI QX80 and to request that INFINITI consider a safety recall or other appropriate remedy. The screen is malfunctioning by going black, freezing, failing to come on, and repeatedly turning on and off while I am driving the vehicle. This is not simply an inconvenience. Having the display repeatedly shut off and restart while the vehicle is in motion raises a significant safety concern. The screen is an integrated part of the vehicle's infotainment and navigation system and may also be connected to the vehicle's rear-view camera system. A malfunctioning display can interfere with the driver's ability to access important vehicle information, navigation, and potentially the backup-camera image. I am concerned that this may be a defective component or system affecting other 2018 INFINITI QX80 vehicles. I respectfully request that INFINITI investigate whether this is a known or recurring defect and review complaints and repair records from other QX80 owners. I am requesting that INFINITI: 1. Investigate the cause of the screen repeatedly turning on and off while driving. 2. Determine whether this is a common defect affecting 2018 QX80 vehicles. 3. Review previous complaints, repairs, and warranty claims involving this system. 4. Determine whether the problem presents a safety risk. 5. Consider issuing a safety recall or providing a safety-related repair or replacement remedy to affected owners. 6. Provide me with a written response regarding INFINITI's findings and any available recall, service campaign, warranty extension, or other remedy. Vehicle: 2018 INFINITI QX80 VIN: [XXX] Mileage: 131,000 Problem: Infotainment/navigation screen goes black, freezes, fails to come on, and repeatedl INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

AIR BAGS
Airbag light came on out of the blue. No accidents or anything done to cause light to come on just random. Was advised by dealership “ FOUND CODE B0020 SIDE MODULE OPEN IN DRIVER SEAT AIR BAG, CODE IN PAST WHICH REQUIRES AIR BAG CONTROL UNIT REPLACEMENT-- NOTE AIR BAG SYSTEM IS DISABLED WHILE LIGHT IS FLASHING, NO AIR BACS WILL DEPLOY IN CASE OF ACCIDENT * REPLACE DRIVER'S SEAT AIR BAG ASSEMBLY AND AIR BAG CONTROL UNIT-- PARTS ARE SPECIAL ORDER. Was told it would be $3887.93 to fix. Why this is not a recall issue is beyond me especially given the amount of complaints as of recent and over the years regarding this same issue. Extremely disappointing!

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.

SUSPENSION
The contact owns a 2015 Infiniti QX80. The contact stated that while driving at 60 MPH, the rear passenger-side wheel began to detach from the control arm, causing the driver to lose control of the vehicle. Despite the failure, the contact was able to pull over to the highway shoulder. Upon inspection, the contact observed that the rear passenger-side tire was resting at a 45-degree angle. The vehicle was towed to an independent mechanic, where it was discovered that the rear control arm was severely corroded. The mechanic then informed the contact that an unknown TSB was related to the failure, and the contact was referred to the manufacturer for assistance. The manufacturer was notified of the failure and informed the contact that there was no recall or warranty coverage on the vehicle. The contact was provided a case number and was referred to the dealer, who determined that the entire rear subframe needed to be replaced. The dealer had given the contact's mechanic an estimate for the repair. The vehicle had yet to be repaired and remained in the mechanic's possession. The failure mileage was approximately 135,000.

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.
