What is the age and condition of the battery? If original, it may be weak/failing. Chrysler computer modules do not tolerate low voltage conditions.

I'm not seeing a U0145 for this car. Are you sure?
Yes, battery must be in good shape with clean & tight terminals.

The P2172 is the 'vacuum leak' code. It was also addressed in a PCM software update in 2018. Has the car had the oil consumption (W20/W84) or catalytic converter (U90) recall done yet? The software would be updated during the recalls.
Used? Just purchased? If Chrysler doesn't know that you have the car, you may not receive recall notifications.

Do you hear any 'hiss' under the hood? Can you locate it? Check vacuum hoses on or around the throttle body. Especially the PCV hose could crack (you might not see the crack until you pinch the hose.
Worst case might be a failed throttle body assembly.

The C121C is an ABS code. It is probably related to the P2172 as dependable engine torque may be needed to get out of a skid. The ESP system resides in the ABS module as both systems use the brakes to assure stability during a loss of traction.

The U0145 being a 'U' code is probably related to the CAN bus network communications between the modules.

Don't replace any more parts. Let's diagnose first.

U1424 was also addressed in the same TSB as the P2172. If you replaced the PCM, do you know if it has the latest update? Is there a label on the PCM with a part number?

Has PROXI been performed with the 'different' PCM? Is the odometer display flashing?

Follow the 'Possible Causes' for C121C, but I think that it is because of P2172.
See 'Possible Causes'. Rule out any engine/exhaust defects for P2172. Use the correct motor oil.

The BCM communication Procedure is attached for the U1424 step.

What symptoms do you have? Loss of power?

What am I supposed to be seeing above?
RTE LOW-Range to empty low. Avoid running low on fuel.
The car drives OK, but stalls when decelerating?
