I am having the same exact problem.  The driver side LED lower accent light on my 2019 Limited is not lighting.  I would just turn off the other accent lights if I could, but that doesn’t seem to be possible.   When I took it to the dealer to get replaced under my 5/100 MaxCare warranty, the warranty department rejected the request.  The policy does exclude bulbs, but I would argue that since this is an assembly and not just a bulb it should be covered, especially when they just quoted me $1,710 to replace it.  When I purchased the extended warranty, my dealer specifically said that this is the ultimate bumper to bumper warranty, just like the factory warranty, but with a $200 deductible.  It would cover everything except normal wear and tear items like tires and brakes.  This is a faulty Mopar part, not normal wear and tear.
@RamCares - is there anything that you can do to help us out here?
