Toyota Motor Corp. said Thursday that it is investigating the computer-regulated braking systems of all other hybrid models, such as the Sai and the Lexus HS250h luxury hybrid sedan, following complaints about its Prius hybrid model. Toyota said that the recent brake problems in its smash-hit Prius hybrid gasoline-electric vehicle involved computer software used in automated systems and said it did not try to "cover up" the glitch.
