Toyota Prius NHW11
What the hazard is
In the worst case, the steering operation may be temporarily limited.
What to do
All owners of affected vehicles will be contacted at their last known address by recall notification letter. Owners are advised to contact their authorised Toyota dealership for inspection and replacement of the nuts that secure the EPS pinion shaft. This will be performed at no cost to vehicle owners.
Defect
In the electric power steering rack and pinion assembly of affected vehicles, if the steering wheel is frequently turned to the full lock position with high force, there is the possibility that the nuts that secure the pinion shaft may become loose. If the vehicle is continually operated in this condition, the pinion shaft clearance may change, causing power generated by the EPS motor not to be fully transmitted, resulting in reduced power steering assistance.
