Regarding my charger being faulty - I assume you mean my wall unit? - I doubt it. Only because I previously used it for 2.5 years with my Focus Electric. I did have a problem with it for a while, but it was a faulty cable that sometimes let the car start charging and sometimes didn't. I sent it back and they replaced the cable. No problems in the 2 years since. Anything is possible, but since I'm not the first to have the running fan issue, my money is on the car being at fault.

If I can cool the garage and the fan stops, well, I don't know. I don't think it should stay running and heating the enclosed space by default. Doesn't anyone else keep their car in an enclosed garage?
Did you happen to look through the front grill to see if the shutter was open or closed?

I keep both my 2014 Spark EV and 2015 Spark EV in a closed garage although, in hot weather and while I am awake, I keep the garage door raised about 8 inches. Lately, garage temps in the early evening have been running 90 to 100 deg. F at the car level.

Forgot to say, yes I again checked the vent louvers and they were open. I sat outside for the last hour plus, garage cooled down, fan never stopped running. I came in and unplugged it and the fan cut off. I plugged in again and will check in a little while to see if the fan comes back on.

What type of EVSE are you using to charge the car?

I also have a home built Juicebox from back when they offered kits. I added a kWh meter to it.

Just to clarify, an EVSE is just a Big Ass relay in a box. It's either On or OFF.

There is a pilot signal it generates to tell the car it's rated max current. I set mine to 3.3 kW because of the J1172 cord I bought from amazon.
An EVSE also has GFIC system for safety.

I don't think there is any way for an EVSE to make an EV act the way this one is doing.

One worst case is the TMS is all messed up and it is running the AC compressor and running the battery heater at the same time.
That scenario would produce heat all night long after the battery has topped up.

Hey !! Try a Hard Reboot. Remove the negative 12V battery terminal under the hood. Leave it disconnected for ~ 5 minutes.
At the most you might lose your radio presets....

Good luck !

3 step Trouble Tree, 1st try car died again, 2nd try not covered / cost $800. 3rd try fixed the problem.

Thanks I will try that.

Disclaimer: this is me guessing at stuff.

To me, it seems like something is not telling the the fan to stop, because it doesn't seem like the computer knows that the battery is full. I base that theory off of the fact that I don't get the text that the car is fully charged until after I start the car. Last night, after the car finished charging, I went and unplugged it. The car sat the rest of the night (a few hours, really, since I woke up around 3 and did it), but the text came after I got in and started it and was backing out of the garage to go to work. Same thing every day.

I haven't called the dealer yet. The one I will need to go to is not super convenient for me.

With respect to the "Charging Complete" message - I do not think it means much. After spending all night connected to my L2 EVSE, I disconnected my 2015 Spark EV at around 8am this morning. After charging, the car was not powered on until my wife left at 2:20pm to run some errands. I just received the "Charging Complete" notification in my email at 2:20pm.

But that's what I'm saying - that non-notification isn't good. Something isn't working right if the notification isn't happening when the battery is actually topped off and instead only happens when the car is started.

I agree, part of the puzzle. Who knows, maybe the reboot might reset a bunch of SW.
Might not.

Then,, good luck getting a dealership to understand what you are experiencing and take it like it's a serious problem.
I got the feeling with my Volt that it's a matter of pride with some techs not to call the Mother Ship for Tech Support,,, even though these are complex EV's and the techs can't be expected to be experts on all the issues they can have....

Oh well, I'm really happy my Spark EV has been rock solid !!!
I get my charge complete txt everyday, like clock work from my car! It makes me fell wanted! ;)

I'm not sure that the notification indicates anything other than the link between the car and OnStar is flakey at best. After a few months, I stopped getting notifications until I started the car. Every couple months, I start getting the notifications on time, but only for a few days and then it is back to the delayed notice. It has never affected the actual charge or the fan though.
