The TSB was published on October 31, 2013. Fisker filed for BK in November 2013. I seriously doubt it has been addressed in anyone cars.
in case you need it

Yes. This bulletin was posted to our tech site well after things were shut down. However there were a few employees that remained throughout, one being a drivetrain engineer whom Harleyguy and I know. He put this bulletin together and posted it for us. However, to say its a serious issue is exaggeration. I've never seen one loosen up. Not even one. So nothing to panic about. Even if that axle nut were to come off, which is nearly impossible if you saw it, the axle couldn't come out of the splined hub. Its more or less something for us there look for when servicing. These bulletins are common. I couldnt imagine if car owners had access to all the bulletins we see they'd sell their car ;)

thanks FiskerPhilly, for putting in perspective. I just put my torque wrench back in the cabinet. In 26,000 miles, not an issue, will keep in mind if there is any work done on the Axle.
