A vehicle door latch has a rotatable fork bolt that is latched by a detent in primary or an intermediate secondary latch position. The detent is operated via an intermittent lever that is operated by a transfer lever that is actuated by inside and outside door handles via suitable mechanical linkage. The door latch includes a locking lever that disables the door handles from operating the intermittent lever when it is in the locked position. The door latch also includes a cinching mechanism that automatically engages the fork bolt in the primary latch position when the intermediate secondary latch position is reached. The cinching mechanism shifts out of the way responsive to an unlatching operation to provide a fail-safe feature.
