Ouch... I toad a 2010 JK Wrangler (all four down on pavement), tranny and transfer in neutral, steering wheel unlocked, and have never heard of this problem. Last trip was Seattle to New York and back. Zero problems.
Please post results of your final diagnosis... that’s a serious problem.
I can’t imagine being on an interstate or heavy I-5 traffic in Seattle and having that lock-up happen. Very dangerous. Glad everyone is safe.
