Had the same issue with the ATV teleporting, and it would randomly teleport into positions where it would take damage until it exploded. After fixing it when it exploded the first time, it was still doing the teleportation issue until it exploded again and is now clipped into the wall outside near the ATM where I cannot recover it anymore. If I try to drag it, it doesn't move. If I try to ride it, it explodes. If I use the hook to try to pull it, it doesn't budge. So I have been having to hoof it everywhere. No idea how to fix it other than just starting a new save.
