There's a sub in r/Stellantis that confirms they filled up lots with trucks that have electrical and software issues and they're trying to rework the trucks.
Sort by date, it's only a day old.
Apparently CEO is visiting SHAP on 8/23 because of the **** show.
Edits:
Here's the link
MCA = Mid Cycle Action (AKA the 2025 refresh).
Highlights: Vehicles waiting to be reworked are being stored offsite on other Stellantis lot since they didn't have enough space to do so at SHAP. They've brought in an "outside team" to help with the rework, but a poster alludes to that not going well.
