No it does not. However motor failures resulting in a crash are so rare as to be almost a non-issue. I'd been in this hobby for quite a while. Even in the early days of the Phantoms (or prosumer drones), crashes due to true motor failures were extremely rare. Quads falling out of the sky were almost all attributable to props not being properly tightened and falling off...
Having several DJI drones, and frequenting their forums I've not seen a crash attributed to a motor failure in ages. Even the new Mavic, I've yet to see a post on Mavicpilots where someone has lost a motor... Also just look on this forum, I can't recall the last time, if ever, I've seen a post where an H has lost a motor in flight which was not due to "pilot error" hitting an object first (or damaged in an earlier flight but the pilot did not notice the damage then flew again where the motor died), like a tree causing a lost motor.
My point is drones have come a long way and motor failures on "prosumer" drones is rarely a problem now-a-days. You're more likely to have issues with GPS loss resulting in the loss of your drone.
