| Air Bag problems |
Airbag light turn on, on my dashboard, I checked it with a professional obd2 scanner and shows a code which indicates a fault in the occupant detection system (ods), which the scanner says it is very common for my vehicle. This puts my passengers at risk due to an airbag system fault. My vehicle has not been in an accident, nor has my passenger seat been messed with. I have spoken to other individuals with the same vehicle, also checked the forums for my specific vehicle and almost all of them have the same issue with the ods, with no recalls or warranty resolution from the dealership. This is a common issue. It is concerning because there is a pattern of the ods being faulty by no fault of our own but no resolution or recall.
Within one month of purchase, the airbag warning light illuminated and has remained on continuously. A separate dealership later confirmed the airbag system is defective and may not deploy in an accident. This is a serious safety defect that was not disclosed to me at the time of sale. Additional issues: •on July 14, 2025, I dropped the car off for prolonged starting issues. I was told the vehicle had six faulty fuel pumps/injectors. •I have not had possession of the car since July 14. •on August 30, 2025, I received an email from Nissan of orange park stating the car was “completed and ready. ” when I called the next day, I was told the car was not at Nissan at all, but at Infiniti, with no clear repair status or timeline. Concern: this is a federal safety defect. I request NHTSA’s review and investigation into Infiniti/Nissan’s handling of defective airbag systems in this vehicle and the misleading communication surrounding repairs.
The airbag/srs light is on. I've read on multiple forums that this is a common occurrence with this model and year of Infiniti. It did not come on as a result of any accident/incident.
The airbag passenger light is illuminated causing air bag system to remain off until resolve. The vehicle was taken in for inspection and dealer confirmed diagnostic results found occupant sensor malfunctioning. Under warranty, the sensor was covered, but after installation the system also found that wasn’t the only thing to replace. It’s a handful of sensors and harness that is integrated within the seat frame with the only solution to replace the entire chair/seat frame. This item does not fall under warranty. My concern is the safety of my family riding in the vehicle. This issue was happening to 2016 and 2017 models that were recalled for the same issue. Unfortunately this vehicle may have been manufactured in 2017, but holds the 2018 year on paper found through carmax.
The air bag system on a 2018 Infiniti Q50 awd is malfunctioning. I’d like to get it checked out especially if this could be a tentative recall issue for myself and other owners of the same vehicle. I feel very unsafe for my family and I because the system was never tampered with, yet the light used to go away randomly. Currently, the light is permanently on, and passenger airbag light states the system is off from deploying in case of an accident. This would mean that I would be driving at a risk of airbags being non-deployable and that is truly unsafe. This problem was not addressed with a dealer or any other service center. The vehicle has never been inspected yet, but it is a concern that I’d like to move forward on. The passenger airbag light is illuminated on my dashboard as well as the light depicting that the system is off. I recently bought this car July 2022 and within six months from purchase the light started coming on randomly and disappearing. Now it is permanently on.
