Toyota is recalling 5,409 UK-registered Yaris and Verso-S models built between November 2010 and March 2012 to rectify a possible fault with the power steering system.

A coil wire used in a power steering relay may have been stored without the correct humidity control during the manufacturing process.  As a result, it may have absorbed moisture which could condense and form water droplets on the relay terminals.  This could cause a short-circuit, which would prompt the power steering system to suspend power assistance.

The problem would manifest itself as a heavier steering feel, especially at low speed.  A warning light, accompanied by a beeping sound, will be displayed on the instrument panel.

The issue is said to affect 174,000 vehicles worldwide, with 5,409 of those registered in the UK.

Four reports of the problem occurring in the UK have been received by Toyota, but there have been no reports of accidents or injuries related to the issue.

Owners of affected vehicles will be contacted by Toyota GB over the next few weeks, and will be invited to make an appointment at their nearest Toyota dealer to have the power steering electronic control unit replaced.  Rectification work will be carried out free of charge and will take approximately one to two hours to complete.

Yaris and Verso-S owners can check if their vehicle is affected by visiting the owners section of the Toyota website, or by calling Toyota Customer Relations on 0800 1388744.
