I'm not sure whether this thread can be revived or there is a more relevant one, but my 2018 Clarity (with 55k miles) consistently charged to normal driving range (mid to upper 40s) until just over a month ago (January 2023) when full charge suddenly dropped to a disappointing, very consistent 32 or 33 miles. OBD said the battery capacity was 46Ah. Low enough, I guess, to explain the change but not low enough for Honda to replace the battery pack so I haven't taken it to a dealer. I just got back from a road trip of 800 miles with no charging, and on the first charge after getting home, it showed 69 miles! Battery reading is still 46Ah. I've gone to town and back a couple of times (less than 10 miles each time) and charging after each trip has resulted in 65+ miles EV. Maybe I need to drive it down to zero and then see what a charge produces, but does anyone have an explanation for this???
