This problem has plagued several Jeep models. Thanks to the Jeep community I was able to identify the issue and get the fix without spending myself silly.
Using the Veepeak OBDCheck BLE Bluetooth OBD II Scanner Auto Diagnostic Scan... $34 after tax & Prime shipping + Car Scanner ELM OBD2 free version Car Scanner ELM OBD2 – The best car OBD2 diagnostic solution for iOS and Android in your pocket!
I confirmed that indeed the rear left ABS antilock brake sensor (Mopar part # 68309279AD)
was bad. Once replaced all systems were back online.
The following issues were all solved with one <$40 part:
Dynamic Steering Torque Service Required
Service ESC System
Service Antilock Brake System
Service Parking Break
4WD System Unavailable Service Required
SERV 4WD warning light
Parking Break warning light
ABS warning light

We have three 2018 Compass' and one of them is having this issue. I changed out the batteries ( both of em) and it was fine for a few months but now its back again. Thanks for the links and info. I ordered up the scanner and hopefully I can start diagnosing it..

Using the scanner I get three codes.. U0140 (BCM NO COMMUNICATION) U0420 ( invalid data power steering module) and U110a.. Taking it to the dealer tomorrow to see whats up. Car has only 18,000 miles on it but its out of warranty due to time. Should NOT be having these issues with such low mileage.
