Due to a manufacturing fault, bolts holding the curtain airbag in place could have the bolt head detach, meaning the inflator may not be correctly secured.
If the condition occurs, Volvo says the functionality of the inflatable curtain could be decreased, which could increase the risk of injury in a crash.
The VIN ranges for the affected model lines are as follows:
Interestingly, the V90 Cross Country (below) is included in the recall despite the fact it isn't officially on sale in Australia yet, while the regular V90 appears to be unaffected by the notice. V90 CC models recalled will likely be dealer stock and vehicles still in holding or transport.
Known owners of the recalled models will be contacted via mail, and are encouraged to contact their local Volvo dealer to have the curtain airbag bolts replaced free of charge.
