Infiniti
Qx80

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.

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?

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.

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.

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 if this is investigated you will find that this is a common issue with almost every Infiniti QX 80 2017 and also some more year makes and models please investigate so consumers can be helped with this issue it’s also a safety concern as yes the vehicle needs acceleration in order to avoid a collision is not possible due to lack of power because the TCM and ECM is not communicating in order to downshift to give the power to the vehicle to get out of the way of a collision I have almost gotten into a wreck several times in stop and go traffic between the Rpm’s listed which are between 1020 500 RPMs as well as gas mileage has cut in half due to this issue and sometimes shifting we get stuck in one year or the other which normally is a higher gear therefore has no power to go we need it sometimes I have to turn the car off at stop signs or stop light in order to restore it so I did not cause a rear end collision by somebody running into me NHTSA serviced bulletin- consumers have to pay for Ben though know issue infiniti won’t take responsibility Reference: Date: AT17-002a ITB17-008a April 18, 2017 2017 QX80SHIFT SHOCK, LACK OF POWER, AND/OR RPM FLUCTUATES INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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.

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.
