2017 Infiniti QX80 Complaints

AIR BAGS — Filed 07/10/2026

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!

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.

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 — Filed 10/07/2024

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.
