    It’s spring now and i usually get 50 plus ev miles on a full charge.

    Went to the dealer to get 4 service bulletin addressed:
    18-096 emission warranty cd product upate
    18-089 evtc and 3 way valve software update
    18-091 driver display software update (hv range too high)
    18-090 climate control unit replacement
    I got a letter from honda for all these sb

    After the service, i notice my ev range went down. It was 42 yesterday and 43 today.

    Anyone have this experience?

    Btw, i got the hv range issue fixed last year under sb 18-069, my ev range did not change after that. Not sure why they “fixed” it again under a diff sb.

    SBs are effectively firmware. As least one of the 18-09x updates requires a complete system reboot. Your range estimate starts over as if the car was new.
