Another question. Would the reading be accurate right after shutting car off. Should I have waited a few minutes for everything to power down?

I don't know anything about the machine, but I'd personally wait until the car has sat overnight or MANY hours before checking w/a volt meter.

Putting the car into READY (car green car w/arrows) engages the DC to DC converter and thus will charge/maintain the 12 volt battery, raising its voltage. I know nothing about the unspecified machine and don't know if it does a load test (or a good load test).

If you had Leaf Spy Pro, you could read the DTCs (Diagnostic Trouble Codes) and even clear them, to see if they return. Leaf Spy Pro REQUIRES an OBD2 dongle that is known to be compatible with the app. Don't just pick a random one or use someone's unknown filter/tool to pick one.

I’m thinking I just might purchase both the leaf spy app and the obd2 dongle that goes along with it. I’m sure that the technician is gonna charge me a lot just to find out the same thing I could find out. I’m also going to test my battery again after it has been sitting a while.

I’m just surprised that from what I’ve read on here and various other places, I’ve been unable to find anyone whose power steering isn’t working, but they’re able to drive car. It seems other folks who experienced this weren’t able to put the car in drive.

Thank you all so much for the assistance

It will be interesting to see the resting voltage after a while although I don't think we necessarily know how/if the DC-DC converter maintains a float voltage across the terminals. A fully charged lead acid battery should be in the 12.8 - 12.9v range according to google.

It’s just interesting that I haven’t found one other case where the power steering wasn’t functioning and they were still able to drive. I’ll test battery after it’s been sitting for a while and post those results. This has been perplexing me since monday

In case you do test the rest voltage, a Leaf typically reads 12.5-12.7 volts. 12.4 isn't likely to mean the 12 volt battery is the issue, but lower than 12.3 might. And yes, your problem is unusual.

I have read that Autozone will load-test your battery for free. Gives a better health reading than just measuring the resting voltage.
I noticed you're still working with polymers.

True. Just keep in mind that they may "fail" a battery that can still easily start a Leaf because there is no high-drain starting motor.

I’ve been driving the car since Monday and it’s been starting up just fine everytime. Literally everything works sans power steering. Is it harmful to the car to drive it without power steering? It’s a pain to steer of course. I have to drive it like this til the 20th. That’s the date that the leaf tech can take a look

I wouldn't have suspected the 12V battery. The battery would have to have a shorted cell or something like that and then the car wouldn't even go into drive mode.
