Toyota has decided to recall 2.7 million cars worldwide because of problems with the steering wheel and water pump system.

The recall affects nine models, including the Toyota Corolla and the second-generation Prius.

It comes four weeks after the firm recalled more than seven million vehicles worldwide, including some Corolla and Camry models, over faulty window switches.

Toyota is Japan’s biggest carmaker.

Joichi Tachikawa, a spokesman for Toyota, said the problem with the steering wheel was to do with “insufficient hardness of the steering shaft”.

He explained that due to this, the splines which connect the extension shaft to the gearbox may deform if the steering wheel is “frequently and forcefully turned to the full lock position while driving at a very slow speed”.

“This may create an increased backlash and the splines may eventually wear out over time, which could result in loss of steering ability,” he added.

However, Joichi Tachikawa said that no accidents due to this fault had been reported so far.

Toyota’s reputation was damaged in 2009 by a recall that ended up involving 12 million vehicles and fines from US regulators.

The Japanese carmaker is still trying to rebuild its reputation and regain customer trust after that fiasco, which saw the firm’s head apologizing to consumers.

Its efforts to do so have been dealt a blow over the past few weeks, as it has announced recalls totaling nearly 10 million vehicles.

However, some analysts said that while the latest recalls, which are voluntary, were a setback, they might not cause as much damage to its reputation as the ones in 2009.

“Nobody is perfect. Vehicles nowadays are very complicated,” said Koichi Sugimoto, an auto analyst with BNP Paribas in Tokyo.

“The company is taking appropriate measures to fix the problems, so I don’t think this will cause significant damage to Toyota’s reputation.”
