Toyota has added the brake systems of the latest Lexus hybrid vehicles to a growing list of problems with various models, the company said Friday.

The company said it was checking the brakes on the Lexus vehicle model HS250h — as well as a Japanese model called the Sai — because they use the same system as that used on the 2010 Toyota Prius.

Toyota has announced no recall of these vehicles, however, and said it has not received any complaints about the brakes from consumers.
