    My car won't charge. It's plugged in, in the garage, as usual. The mechanism on the charging cord shows the green light, so it thinks it's charging the car. The port on the car shows a green light, showing that it is indeed connected. But the blue flashing light doesn't come on, and the dash message shows that the car needs to charge.

    It will charge after about three minutes, I've seen the same thing and it happens occasionally

    Yes, as @priuscatprimeguy mentioned, occasionally there is a several minute delay before charging starts.

    When it first happened to me, I tried plugging and unplugging the car several times and finally learned to just wait until the Prime decided it wanted to start charging.

    No idea what causes the delay either btw. Possibly the battery pack is too warm, but I can do the same driving pattern and it will charge immediately 10 times in a row and on the 11th it just takes it's sweet time...

    Literally had the exact thing happen to me this morning. Seems to be charging fine now though. I did get an error message that said to check plug, but all seems ok now.

    Huh - the check plug error isn't something I've ever seen. Odd.

    I’ve never seen it either. It was on the entune app not on the car anywhere but still. It was just odd all around

    I've seen this a couple of time and posted about it. I am not sure, but I suspect it has something to do with the traction battery being too warm and the Prime delaying the start of charging until the battery cools down a little.

    It could also be a software glitch where the car thinks it should delay charging as if it were on a programmed schedule. I never use the program schedule, but on very rare occasions, the car acts that way.

    Because I have a 2017 Prime with the advanced trim, once when this problem occured, I checked on the car using the Entune charge management app on my cellphone. It showed the car not charging and with the app asking if I wanted to charge now. I selected 'charge now' and the Prime went into charging mode.

    Also worth noting: when this problem has happened, my Level-2 EVSE clicks on normally which indicates that my Prime has successfully completed its handshaking routine with the EVSE and that the EVSE has connected the 220-volt supply to the vehicle. However, when I look at the power meter which I installed, it shows the Prime drawing only about 1 amp or less rather than the 15 amps which it normally draws when charging. 1 amp is considerably more than the EVSE draws when it is idle with no car attached, so I assume the Prime is drawing some nominal current while waiting to begin charging in earnest.

    Sometimes i have that problem at the public charger. No idea why. I just disconnect the cable from the car and try again until it connects properly.

    Make sure you don’t have a schedule set to charge. If you do then it won’t charge even if plugged in until the scheduled time comes. Happened to
    Me before
