Toyota Motor Corporation (TMC) has announced that it will recall 2.7 million cars worldwide because of separate problems with the steering and water pump systems. The voluntary recall affects nine models, including the second-generation Prius hybrid.

Cars brought back will have their steering intermediate extension shaft replaced. Due to insufficient hardness treatment of some of the extension shafts, the splines that connect the extension shaft to the steering gear box may deform if the steering wheel is frequently and forcefully turned to the full left or full right position while driving at slow speeds. This deformation may create increased internal clearance and the splines may eventually, over time, wear out.

The other issue involves the electric water pump for the hybrid system. The pump circulates coolant through the hybrid components. There is a possibility that the electric motor installed in the water pump may stop functioning, leading to illumination of various warning lights in the instrument panel. In limited instances, the electric power supply circuit fuse may open, causing the hybrid system to stop while the vehicle is being driven.

No accidents due to the above issues have been reported.

In Malaysia, UMW Toyota Motor (UMWT) released a statement saying that it that had received confirmation from TMC that there are two units of the second-generation XW20 Toyota Prius (the current Prius is the third-generation) sold in Malaysia involved in the recall. Besides these two units, which owners will be contacted by UMWT, no other Toyota and Lexus cars are involved.
