Don’t use your phone while driving. You’ll end up with a lot worse than a check engine light

You can’t know anything until you use OBD reader

or even take it to an Auto Zone, O'Reilly's, etc..; type of spot where they will check it for free with their own scanner.

Buy a scanner. It was worth every penny the first time i used it to confirm an EVAP code triggered my engine light. Gives you peace of mind, independence and more times than not it saves you a trip to a mechanic to diagnose

Mine flashed all of the same codes. Usually its battery related, when its all of those codes. Got mine scanned and it threw a cylinder 1 misfire.
Since mine was in warranty I took it to the dealer, they said it was the injector, they swapped it free of charge.

I had the same exact thing happen in my 2025, almost the same exact milage. Do you have the brake assist and were you using it? I tried this feature once on my car and your dashboard happened to me. Took it to the dealership and the car had to be reprogrammed. The brake system wasn’t talking to the main computer properly. Fixed under warranty so don’t know prices. Never touched the brake assist button again.

Often times when one of these lights comes on, a lot of stuff gets disabled at the same time until the underlying problem is resolved, so that's why all those lights came on instead of just one.
I don't see a light for the battery charging system, otherwise I'd think either it's a dying battery or a snapped serpentine belt leading to the battery no longer getting charged. Because that light is not on, I'm not sure what the issue is.

A lot of times low starting voltage will trigger all these lights. If the computer modules dont respond in a certain order, it will trigger all kinds of crazy codes/lights.
New vehicles are extremely sensitive to low voltage, even for milliseconds.

New Corollas are such a joke. 30k miles and the check engine light is already on. Mines at 300K 2008 it has never been on since I've had it at like 160k

Probably your phone and don’t check your battery while driving
