Not falling for the flame bait but you may not want to be around any nuclear active zone with cars, those things are like radiation magnets.
Find a new frame, transfer your armor over to it
Try it. If it works, look for 2 more. Or load a old save. All you can do unfortunately. Unless your pc.
Sorry all that can be done
Try making a video of it and bug report it
Not the first time I've heard of this actually. Seemed to have something to do with removing the armor while under water or something. No 'cure' was ever really figured out for it though. Definitely a game breaking bug though.
