Toyota has been forced into yet another recall, after a problem emerged with the steering on two models. Worldwide, 174,000 cars have been affected. In the UK, 5,409 Yaris cars have been recalled.

So what's the problem, and what should you do?


Fault

Toyota said that the problem is a wire in the power steering control unit, which in some instances was stored incorrectly during the manufacturing process. The wire absorbed moisture, which may condense inside the unit and form water droplets. This can cause a short circuit, which causes the power steering to fail.

When this happens, the steering will become excessively heavy - especially at low speeds. At the same time a warning light will come on and an alarm will sound.

So far the steering has failed on four cars in the UK - although there are no reports of any accidents or injures as a result.

The fault could affect Toyota Yaris third-generation cars and the Verso-S mini-MPV, made between November 2010 and March 2012.

What can you do?

If your car is affected you will be contacted by your local dealer, who will arrange a time for you go in and have the fault fixed for free. The dealer will need to replace the unit, which should take around two hours.

If you are concerned as to whether your car is affected, you can check it yourself on the company's recall checker site.

This is yet another blow for Toyota, which has recalled an astonishing 13 million cars in the last five years. The company may have hoped to shake off its association with recalls after the massive recall in 2009 and 2010 over faulty accelerator pedals - which could get caught in floor mats, and lead to uncontrollable acceleration.

The latest in a long line of recalls is not going to help them put this behind them.
