So last thurs I got this historic code p018C and MIL.
couldnt clear it but I was keeping an eye for it to pop again as an active code.

Friday no code(still MIL for 3 drive cycles)

Sat it popped up active again.. I dropped it off at the dealer.

They ordered a fuel pressure rail sensor (not sure if this is the rail too or just a sensor that plugs into it)

Today.. still throwing code with new sensor.. they ordered a PCM..
first issue with the 2019.. at least I got the free fwd loaner just in time for winter storm
instead of my trailhawk with blizzaks.. /joy.

from what I gathered from google searches, it doesnt appear to be very common with jeeps, although alot of chevy hits pop up when I was searching.
 
My guess is the PCM will not fix it either. This code is for lower than expected signal. Wiring harness or loose connection would cause such a condition on a new vehicle.
