The Swedish company reports the right-hand side seatbelt pre-tensioner for the third row of seating may have been produced incorrectly.
Volvo says the seatbelt itself will operate as normal for general use, though a small part of the assembly could detach in a crash.
If the condition occurs, the part could bounce into the passenger area, increasing the risk of injury to occupants.
Affected XC90 SUVs fall within the VIN range 133955 and 143647. Volvo has confirmed there have been no incidents caused by the issue in Australia.
Owners of the recalled units are advised to contact their local Volvo dealer to arrange for the repair of their XC90.
