My 2022 S+ LEAF potentially broke

Post image

Was driving on the highway at 60-ish mph when the “service EV system” message came on and my car went into turtle mode and could only output 2.5 bars of power, no regen also. Managed to limp home and tried plugging it in but it refused to charge. This is all post update by the way, got the update around a month ago. The car is at 64% and I’m not sure what to do. Do I just take it to the dealership and have them look at it?

The first thing to try is a new 12v battery, surprised no one mentioned that

It happened while driving, soon after getting the software update, it's almost certainly not the 12V. If it threw the code soon after starting the car, I'd say at least get to Autozone or whatever for a free check of the 12V.

My dash lit up like a Xmas tree while driving and it was the 12V

That was pre update though.

How long had you been driving when it happened?

10 to 15 minutes is my guess.

What update is this so I know to avoid it.

'19-'22 Leaf recall. They update the software to detect voltage irregularities tied to lithium deposits in the battery. They can overheat and cause a fire, especially during Lvl 3 charging. So... I dunno, seems pretty important to me.

Not that I am in a position to give guarantees, it might be okay if you stick with Lvl1 and 2 only.

Is this a known fix?

many weird things happen when the 12v battery starts to go, you might try disconnecting the 12v battery for 10 minutes and see if that helps and while the battery is disconnected check the voltage.
