Multiple Warning lights

Hi everyone! I have a gen 3 2013 Prius. Around 160k miles

Yesterday after about 40 minutes of city driving, the Prius started flashing “Check Hybrid System Stop the Vehicle in a Safe Place” I also noticed that every other warning light was on, from oil to tire pressure and others.

I pulled over, tried turning on and off a few times with no help. I got it towed home and started googling. I saw people say to check the 12v, I still have the original in it. I don’t have a tester but I tried jumping it for a few minutes and someone suggested to disconnect the hybrid battery for a few minutes from the back orange pull. I realize now that it reset the codes doing that.

I drove it for a few minutes in my neighborhood and the warning hasn’t popped back up.

Today I started researching some more and I saw to check the inverter coolant pump. I opened mine up and it seems to be working, there’s not a ton of movement but there is obvious movement in it. I let the car sit in the driveway on for a few minutes. The hybrid battery charged up a little over half way on its own with the help of the ICE. No warning came back on.

Should I check anything else? would it be safe to try to drive it around again to try to get a code? Or is it most likely just the 12v and jumping it helped it a little bit?

 

Thanks! What's the determining factor that it is the 12?

 

The dealer confirmed it needed a new battery. I had to get one there since my local auto zone didnt carry it and battery plus was out of stock with a long wait time. The dealership also ran a "electrical test" and said everything came back good after the battery was installed.

Today: a few weeks after the battery was installed the warning(s) all came back on after the car was on for about a minute. I've done a little amount of driving, maybe 200 miles since the battery was replaced.

Any thoughts on what to check? I'm going to get it towed in the morning to the dealership as its home right now, but would like to have a few ideas of what it could be to make sure im not being taken advantage of haha.

 

just heard back, the battery is going bad. looking at local places that dont charge a dealer price. Is it save to drive temporarily with the bad battery?
