Too bad they can't honestly tell u what exactly was the cause of the lockup but at least now I think i have a better idea since u mentioned the steering gearsI have a 2018 JL. Long story short, I went to drive one day and my steering wheel was totally locked up. I couldn’t turn it at all. It took a ton of force to break it free. After doing some research on here and in some of the Facebook groups, I found that I wasn’t the only one out there with this steering locking issue. It was intermittent. The dealer couldn’t get it to duplicate but Jeep Cares was aware of the issue. The fix was the 2021 steering box. So far no issues.
