2017 Infiniti QX80 Electrical System Problems

Odometer Fraud. The contact purchased a 2017 Infinity QX80. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. The seller had an LLC. At the time of purchase, the mileage was 90,743. It was later discovered that the mileage on the Title was 175,074 on January 6, 2026. The third-party warranty company that the contact hired discovered the discrepancy and informed the contact that the vehicle had a branded title.

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.

Made a right hand turn and vehicle shut off in traffic barley got into turn lane and vehicle died in the middle of the road, just got lucky a state trooper was behind us to hold traffic off.. would not restart no power, dead battery, put a jumper on the vehicle and it started enough to get out of immediate danger. After replacing a burned up alternator and battery twice it was found the battery current sensor was bad.

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.
