The xD was one of the last vehicles in the U.S. market to get standard electronic stability control, but it now has it standard. Otherwise, its performance in crash tests has been good, but not top-notch.
In Insurance Institute for Highway Safety (IIHS) crash tests, the xD achieved just 'acceptable' for frontal impact, with 'good' scores in side and rear impact for previous model years. But for 2012, the model has been retested and now earns top 'good' scores, as well as the Top Safety Pick designation. The xD hasn't at all been rated by the federal government's new NCAP crash-test program and ratings system.
Otherwise, the 2012 xD's set of standard safety features is competitive: anti-lock brakes, side-curtain airbags in the front and rear, front side airbags, and active front headrests.
