After receiving hundreds of complaints about steering in 2009 and 2010 Corolla and Matrix models, Toyota Motor (TM) is offering to fix the problem -- but only if consumers request it.

After an investigation, Toyota has confirmed that the "design and performance of the steering system is appropriate," according to Consumer Reports' Cars Blog. The world's largest automaker has issued a Technical Service Bulletin that would allow dealers to replace the electronic power steering control unit should customers complain, but Toyota won't issue a recall.

Toyota explained its decision by saying the problem is a design characteristic and not a safety issue. The National Highway Traffic Safety Administration has received some 500 complaints by owners of affected vehicles expressing concern that the cars wander at highway speeds and can be difficult to control, Consumer Reports said.

In not issuing a formal recall, Toyota will avoid having to add nearly 750,000 more vehicles to the 8.5 million recalled this past year, Consumer Reports noted, which will save the automaker costs and legal requirements.
