Toyota Motor Corp. said it knew previously about complaints related to the brakes of its Prius hybrid car and Thursday expanded a safety probe to all its hybrid models.
The Japanese auto maker said it found and corrected problems with its new 2010 Prius hybrid and said it did not try to “cover up” the glitch. But the disclosure and the expansion of its investigation to include such models as its Lexus HS250h and Sai luxury hybrid sedans comes amid intensifying government and public scrutiny of the world’s No. 1 auto maker by vehicle sales.
