Hyundai Motor America (Hyundai) will be contacting the owners of certain 2023 Genesis G90 luxury sedans because of a defect affecting the seat belt pretensioners in their vehicles. The problem could result in an increased chance of injury to vehicle occupants.
In October 2022, Hyundai received information pertaining to an investigation into allegations of abnormal seat belt pretensioner deployments in vehicles associated with recalls 21V-796, 22V-069, 22V-123, 22V-218, 22V-354, and 22V-458. Recall 22V-816 was initiated as Hyundai continued to evaluate vehicles equipped with the same Samsong pretensioners that had not yet been recalled..
In January, during the continued analysis of the airbag control unit (ACU) crash pulse data recovered from a North Carolina incident, they found that the micro gas generator (MGG) separated despite having a lower pretensioner “time-to-fire”. This was the problem that was previously thought to be the contributor to over-pressurization of the pretensioner pipe. Because of this information, the North America Safety Office (NASO) decided to conduct a safety recall 012G (23V-094) of Genesis G80, GV60, GV70, and GV80 vehicles equipped with pretensioners without a vent valve. Recall 012G (23V-094) supersedes Recall 009G, obsoleting all affected population(s) of Recall 211/009G (21V-796).
In March, during the review of details surrounding Hyundai’s assessment of the open investigation into the recent recalls, Hyundai noted that the recent recalls address all U.S. vehicles equipped with the subject Samsong seat belt pretensioner excluding Genesis G90 vehicles. The G90 contains the same seat belt pretensioners but because it is installed facing outward and away from occupants, fragments entering the cabin area and injuring occupants are significantly less likely to happen. Based on this information, the NASO decided to conduct a safety recall (013G) of Genesis G90 vehicles equipped with pretensioners without a vent valve. NHTSA campaign number 23V-210.
According to the defect report, the subject vehicles are equipped with frontal/rear pyrotechnic-type seat belt pretensioners that could deploy abnormally in certain crash conditions. The problem is due to the over-pressurization of the pretensioner pipe. Depending on specific vehicle characteristics such as pretensioner load limiter specification, the airbag control unit logic, crash duration/severity, and micro-gas generator orientation, occupants could experience an increased risk of injury.
Owners of the affected vehicles will be notified with instructions to bring their vehicles to a Hyundai dealer to have the seat belt pretensioner’s micro gas generator and delivery pipe secured with a cap to prevent potential abnormal deployment.
