The official recall notice posted on the Australian Competition and Consumer Commission (ACCC) website explains incorrect specification bolts in the cars' front wishbone suspension assembly may break causing a reduction in steering control. There have been no locally reported cases of the bolt failure.
Citroen sold 66 C4 Picasso and Grand C4 Picasso models in the first quarter of this year and 244 in 2014, indicating that the recall affects the majority of cars sold in that time.
Owners of the vehicles identified by VIN number will be contacted by Citroen Australia.
The bolts can be replaced at any Citroen service centre in a procedure that should take under an hour.
