While driving with cruise control engaged, suddenly the cruise control disengaged, the brake warning light and the abs warning light came on. The required repair was only the forward oxygen sensor, a non-emergency repair. Yet cruise control and abs were disabled, abs being an important safety feature. I was told Subaru has purposely programed the car this way. Not only was I unable to make a decision as to the critical nature of the actual repair but had an important safety feature disabled unnecessarily.
