2017 INFINITI QX80 owner complaints

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.

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 strande

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 ret

The contact owns a 2017 Infiniti QX80. The contact stated while driving approximately 10-50 MPH in stop-and-go traffic, the vehicle loss motive power and stalled with the check engine warning light illuminated. The vehicle was towed to several unknown dealers to be diagnosed. The contact was informed that the TCU (Telematics Communication Unit) and ECM were faulty. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 90,000.

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.

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?

The contact owns a 2017 Infiniti QX 80. The contact stated that while driving at an undetermined speed, the front passenger’s side air bag deployed without warning or impact. The driver was able to park the vehicle and after exiting the vehicle, the remaining air bags deployed. There were no reported injuries. The vehicle was towed to the local dealer but was not yet diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 77,000.

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.

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.

I was driving down a three lane st with no others cars near me. No cars in front or behind of me. When my sunroof exploded.

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

Consistent popping noise from the rear and front of the vehicle which has progressively gotten worse. This issue has effect the overall safety of me family. When driving at rate of speed of about 40-45mph the truck starts to shake making it very hard to keep control. Most recently when making a turn I begin to hear a clicking noise. My vehicle currently has about 27k miles and I have had nothing but problems since I purchased this united in 2017. I have taken my car into the dealership several times for this problem and still to this day no seems to know what's going on. This issue is very unsafe for me and my family and I demand that the manufacturer of this vehicle nissian replace my vehicle immediately.

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.

This is a very common and well-known issue with 2017 Infiniti QX 80 Vin number [XXX] The car RPMs flutter between 1000 RPMs to 2500 RPMs due to the TCM and EC M/ECU TCU failure to the transmission causing terrible gas mileage vehicle stalls in traffic which can cause accidents and has happened over 10 times to me I have called and reported this as well with you all Infiniti will not earn up to the fact that there is a fault and needs to replace the TCU/ECU/ECM/TCM in order to fix the issue I have an extended warranty and I’ve had to pay infinity dealership over $800 now for three different times for them to reflash these modules which does not correct the problem for longer than a week going back to the same issue it’s been an ongoing problem since we have them in the vehicle and I believe
