Hi there same thing happening to me on a Jeep Rubicon JLU 2025 with 1200 miles .
I thought it was the computer learning process but reading here look that goes deep . Anyone with a feedback from Jeep about this issue ?

Brother this is the JL forum, not a JK1 forum.

Yeah, issue is fleet wide. PCM issue. No fix.

Not to bring this back from the dead, but I am working on a fix for this through HP Tuners. Going to have this ironed out in the next few weeks. Look for my newest thread. YouTube instructional videos and some Datalogging goodness too. Maybe some calibrator at Stellantis will see it and make some changes.
