Suggest to get these checked
1. May sound weird but Get Battery Health checked for possible depletion as theser service errors can crop up due to depleting battery too
2. ECU Scan for any faulty sensor and / or clear errors from Scan and then Turn off car for few hours, the start and drive to to Revv engine to 3000 RPM for couple of times and to 4000 RPM then (in 5 to 10 mins) - and later on observe if get any issues.
3. Get Wiring Checked, if any rat bite can cause in these multiple warning signs.
No need to random change in wiring. if Jeep service center is not co-operating, get car inspected at alternate workshop for above or any independent Authorized Unit from prominent one who address on Luxury Cars on above.
Do check out on above and report back on outcome.
