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!

AIR BAGS, ELECTRICAL SYSTEM, LANE DEPARTURE: WARNING
Vehicle acting as a non conforming testing asset running in Factory Debug Mode (Unit ID: 01). This also shows and caused systemic U1000 Electrical Network Jam from an obsolete/unconfigured 2G TCU. Critical Failures: Airbags disabled showing current codes B0022-13(Left), B002A-13(Right) prove the primary curtain airbags are open/offline and won't deploy. Adaptive System Failure: Around View Monitor running Alpha Software(000154) which fails to lock out forward camera at highway speeds creating driver distraction. Ignition Hijack: Code B2401(Ignition Open) allowed vheichle to "Ghost Start" and recognize keys even when sealed in Faraday pouces. Voltage trauma: Sysemic VB Low (B142A-16) prevents vehicle from entering sleep mode, causing persistent network noise. The vehicle was sold as retail but remains in "Unconfigured" Manufacturing state Code: U122A-05. This violates FMVSS 208 and 49 USC Section 30112. AV Control Unit reveals Unit ID 01 and switch software 11401. It remains unconfigured in dubug mode Code: U122A-05, which should have never been for sale FMVSS208. Despite the airbags disabled and network jam codes, Matt Bowers Infiniti Advisor attempted to release vehicle with fraud estimate of $9930.75 for unrelated hardware, and overwrite EEPROM evidence of debug mode. Mfg misclassified VIN as Body: LL to bypass 2017 Nissan Shatai Kyushu Inspection Scandal protocols. This Zombie state facilitates a cyber physical breach (Mac:Private), via unpatched 2015 Bluetooth stack (C201), resulting in massive data exfiltration, possibly part of 25year business loss and now identity theft.

AIR BAGS
The air bag light started flashing. The only thing that I did was have the vehicle oil change and air filters changed. Per the warranty Air Bags are excluded. If the airbags have not deployed or been serviced, there would be no reason to blink unless defective. It costs $2500 for a possible fix and if that doesn’t solve the problem it will cost for the next step and so on. Why is this not a manufacturer issue?

ELECTRICAL SYSTEM, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I am writing to report serious safety concerns regarding my 2017 Infiniti QX80. The vehicle has exhibited two primary issues: 1. Unintended Braking: The vehicle has a tendency to suddenly and unexpectedly brake, particularly when driving over specific road surfaces, such as brick-paved intersections. This behavior is extremely dangerous as it can lead to accidents, especially in high-traffic areas. Such abrupt braking can cause the vehicle to lurch forward, potentially leading to rear-end collisions. 2. Frequent Battery Drain and Failure: The vehicle's battery drains rapidly, requiring frequent replacement. Despite multiple visits to the dealership and attempts at repair, the issue persists. This problem significantly compromises the vehicle's reliability and can leave the driver stranded, particularly in emergency situations. I have taken the vehicle to an authorized Infiniti dealership multiple times to address these issues. While the dealership has attempted repairs, the problems have persisted. The frequency and severity of these issues pose a significant safety risk to myself and other drivers. I urge the NHTSA to investigate these issues and take appropriate action to ensure the safety of all 2017 Infiniti QX80 owners.

AIR BAGS
The passenger air bag system is apparently designed to disarm when a "small adult or child" sits in the passenger seat. This means each time my wife sits in the passenger seat (she is approx. 120lbs,) the passenger air bag light illuminates and the air bag is disarmed. This then renders one of the key safety features inoperable, and she and I feel very unsafe in the car. However, my research tells me that it is designed to be that way. How can that be legal or permissible? This design is deeply flawed and should be addressed immediately. She should not be endangered purely due to her being the weight she is. Not all Americans are over weight. No other car I own or have owned ever did that, only this Infiniti, and apparently all other Infiniti's.

AIR BAGS
My battery died and needed a jump start. Shortly after jump starting my vehicle, the airbag light began flashing. The Infiniti dealership in Milwaukee is quoting $3900 to fix this which seems crazy. I don't know if the airbag will even deploy if I get into accident.

ENGINE, UNKNOWN OR OTHER
I TRIED TO OPEN THE BACK OF THE VEHICLE AND I COULD NOT SINCE I DID NOT PRESS LONG ENOUGH. THEN I TRIED TO DO THE SAME FROM INSIDE THE VEHICLE BUT AGAIN I COULD NOT SINCE AGAIN I DID NOT HOLD THE BUTTON LONG ENOUGH(I BOUGHT THIS VEHICLE FOR MY WIFE AND I WAS DRIVING IT FOR THE SECOND TIME DUE TO SNOW). I THOUGHT MAYBE I SHOULD TURN OFF THE VEHICLE AND TRY AGAIN SINCE MY LOGIC WAS IF THE TRUCK IS RUNNING DUE TO SAFETY REASON THE BACK DOOR MIGHT NOT BE OPENING. AS SOON AS I TURNED OFF THE CAR WITH IT STARTED TO ROLL BACKWARDS SINCE IT WAS ON SLIGHT SLOPE. OUR 3 DAUGHTERS WERE NEARBY AND I WAS SCARED THEY MIGHT BE NEAR THE BACK SIDE BUT THANK GOD THEY WERE ON SIDE OF THE TRUCK. I KEPT RUNNING WITH THE TRUCK TILL I CAN GET IN IT AND STOP IT. I GOT HURT ON MY KNEES AND BLOOD STARTED TO COME BUT I WAS LUCKY ENOUGH TO STOP IT. I WANT INFINITI TO LOOK INTO THIS ISSUE ASAP SINCE I DON"T WANT ANYONE HURT OR EVEN WORSE. IT IS 2017 INFINITI QX80. SEE ATTACHED VIDEO.THANK YOU. (XXXX) OWNER OF THE VEHICLE.

VISIBILITY/WIPER
THE VEHICLE WAS STATIONARY AND PARKED IN MY DRIVEWAY WITH THE WINDSHIELD FACING TOWARD THE STREET. PASSING TRAFFIC EVIDENTLY KICKED UP A ROCK CHIP AND CAUSED THE WINDSHIELD TO CRACK ALL THE WAY DOWN THE MIDDLE. IN MY EXPERIENCE, IT IS NOT TYPICAL FOR A WINDSHIELD TO CRACK FROM THE TOP OF THE GLASS ALL THE WAY TO THE BOTTOM OF THE GLASS DUE TO A ROCK STRIKE WHILE THE VEHICLE WAS STATIONARY RELATIVE TO THE PROJECTILE.
