    It is NOT the EVSE or electrical outlet. The dealer verified with one of their own EVSEs first thing when I dropped it off this morning. I'll know more this afternoon.

    I think I noticed two pins symmetrical to each other that were pushed back an equal amount. Both pins were still out a good amount (not pushed all the way back). My first thought was that was normal but maybe not. Do you have a link to the posting for that?

    Hi , in the J1772 connector there is a pin that carry a function named Control Pilot
    "Control Pilot" is a communication line used to signal charging level between the car and the EVSE, and can be manipulated by vehicle to initiate charging as well as other information.The signal is a 1 kHz square wave at ±12 volts generated by the EVSE to detect the presence of the vehicle, communicate the maximum allowable charging current, and control charging begin/end.
    Dialog between the car Charger and the EVSE looks to be non present.

    There are five pins. Pretty sure the two big ones are for current, then there are three that look like (as noted above) they are used for sensing.

    More to the point, at 12V, even a bit of crap in there (dust bunny, leaf fragment, dead spider) might be enough to interrupt communications.

    Plus, those long thin tiny pins look like they are just begging to be broken. I mean, this is a good design and all. But stuff happens.

    Beyond this, I know nothing. Here's how mine look. I'm sure there must be a better diagram on line somewhere.

    upload_2023-2-20_13-39-19.png

    Edit Looking at an on-line diagram, those pins are, top to bottom, left to right:
    Power Power
    "Safety" Ground "Communication"

    Others label the bottom row:
    "Control pilot" Ground "Proximity pilot"

    From Versinetic: https://www.versinetic.com/news-blog/ev-charging-connector-types-guide/
    • The proximity pilot (PP) pin tells the charging equipment the type of cable connected to the socket – different cable thicknesses can cope with different amounts of electrical current
    • The control pilot (CP) pin provides bi-directional communications between the electric vehicle and charging system. This checks the maximum amount of current that the EV is able to take at any one time.
    Doesn't matter. Pretty sure if any one of those is busted, it won't work.

    Shine a light down the ends of your two charger cables and see if maybe you see a little gleam of copper in the "Proximity pilot" or "Control Pilot" holes.

    I don't think there's a communication problem between the EVSE and the car. When I plug in the EVSE, the charge indicator lights solid yellow. When I start a charge now, that light flashes indicating current flow, but charging shuts down after 5-10 seconds. The green light on the car, which was solid green indicating the car is charging, flashes rapidly, then turns off, indicating a fault. The EVSE charge indicator goes back to a solid yellow. If there was a communication problem, the EVSE wouldn't even indicate a connection to the car. I could be wrong obviously, but I don't think the charge port is at fault here.

    If it is the plug, it should be a cheap fix. I always push mine in very gently.

    It's the charger assembly. Covered under warranty but 2 weeks to get the part. A $2000 part.

    Blame it on the Leviton EVSE. ;)

    Many use the OEM EVSE with a cheap plug adapter to connect it to a 240-V outlet. It is 2.9 kW (12 A) as opposed to around 3.2–3.3 kW on a ChargePoint Level 2 EVSE, but it works.

    No, I don't believe that at all. It's a quality product, UL listed. Might be US made, but not positive. Look it up. Leviton doesn't make cheap junk.

    Doesn't Bisco use one of these? Didn't seem to fry his vehicle.

    I looked at my charging port with a flashlight. No pushed back or bent pins. Everything looks clean.

    Just to clarify, the charger is in the car. The lump on the charge cable is the EVSE, electric vehicle supply equipment, or charging station. It is a smart power supply that communicates with the car's charger, as mentioned above. Without communication you got nothing.

    That's right. I hope when they do the actual work, it doesn't turn out to be Minoks chewing on the power cables. (That's an old Star Wars reference, for the uninitiated.)

    I was wondering why it was still under warranty after 6 years, but I looked it up in the manual. It is part of the hybrid system and is warranted for 96 months or 100K miles.

    The car has been fixed. Charger assembly was replace under warranty, no charge to me.

    congrats!
    interestingly, pip had a bad run of chargers in the later years.
