Toyota said Wednesday it will recall 4,500 Lexus vehicles in Japan to fix a computerized steering problem, with another 7,000 vehicles overseas also likely to be affected.

The automaker has received 12 complaints about the problem in Japan but knows of no accidents that it has caused worldwide, according to spokesman Paul Nolasco.

After being hit with a record $16.4 million fine in the U.S. and facing strong government criticism both at home and abroad for slow responses to safety problems, Toyota Motor Corp. is working to react more quickly.
