I'm in So Cal too....
There is nothing wrong with your car - it's normal and charging is almost 100% as the car determines the ESTIMATED miles per charge.
If you do a search on Google, InsideEVs and here you will see many threads on this "issue".
What you see is not an issue - it's all a predicted representation on how you drive, cabin heating, seat heaters, electrical draw, and weather temps.
If you drive like an old man: feathering the accelerator, using the regen paddles, turning off the cabin heat & ventilation, turning off all electronics including the seat heaters - you will start seeing higher charge numbers.
My style of driving during the week, I see 50-63 miles per charge in the mornings all last month.
That is because I alone commute to work on EV only, slow traffic gets the most regen, no seat heaters needed, no cabin heating (warm Southern California), don't use the infotainment or GPS, and I don't thump the sound system.
However during the weekend, I notice a drop in expected miles per charge as I drive a bit more spirited, more passengers (heavier load), jack rabbit starts, A/C or heating on, music thumping, night time driving with all lights on, etc... So on Sunday and Monday mornings I see 35-45 miles per charge - nothing unexpected due to my driving style.... The range ESTIMATION at the beginning changes drastically depending on how, when, where, temps, etc...
But I can see lately with most of the country freezing under that polar vortex, that cabin heaters and seat heaters were probably being used to the max which will seriously decrease EV range....
BTW: 47 miles per charge is a pure AVERAGE of what you can expect - it's not for everyone in every state, in every situation of driving, in every weather conditions, etc.... 47 miles is a number Honda came up with after testing the vehicle - some may get less while some may get a lot more (like me) - when I drive like an old man, I get a total range of 420 miles (full tank of fuel and 65 miles EV on a full charge) which exceeds other numbers.
Don't fixate on the miles per charge having to be at 47 - that number varies.
If you take all the numbers from every Clarity drive around the nation you will see 47 is an AVERAGE.
