The UX250h along with hybrid versions of the ES and LC are being recalled due to the faulty brake booster pump:
"In the subject vehicles, there is a possibility the brake booster pump may have been manufactured improperly, and in some cases, it may stop operating. If the brake booster pump stops operating, multiple warning lights and messages will illuminate, and/or audible chimes will sound.
In this condition, braking assist could be lost completely after several brake pedal applications, resulting in increased stopping distance. In addition, the Vehicle Stability Control will become deactivated, and other vehicle features could be affected. A deactivated Vehicle Stability Control or a sudden and complete loss of braking assist while driving could increase the risk of a crash."
