Spent a whole day driving my car, stopped at a few places, no warning lights on the dash. I got home and maybe was there for 20min tops when I tried to start my car again nothing turning on, no lights on the dash, no sounds, break lights don’t turn on, nothing. I took my battery to get tested and that checked out fine. I checked all fuses and everything checked out good, I even changed the ignition switch. Still nothing.

 

Any recent work done on the car or any other issues like an accident?

You can use a volt meter or multimeter to figure out where/if you are missing power. First measure the voltage across the battery posts. Then move the red meter lead to where the + battery cable connects to the fuse box and see if you get the same measurement. You can also move the - lead on the meter to where the black cable connects to the fuse box.

Since you have a new battery, the resting voltage measurements should be ~12.6 volts.

 

We already did that and it everything looks good

 

I'm not sure if your car is push to start or has a key. Regardless, the brake lights don't need the key to work, so you are either missing power or missing ground. You can go to the brake pedal switch and use the volt meter to check for 12V on one of the wires. Just touch the black meter lead to bare metal to serve as your ground. I suspect you are misssing power somewhere near the fuse box with so many components not working.

Since you have a volt meter, you can use your volt meter to check if the fuses have power and are blown at the same time. The video below uses a test light, but you can do the same test with your volt meter. Just connect the black meter lead to - battery post and use the red meter lead to test voltage on each tab of the fuse. Your fuses may be good, but you might not have power running to either side.

 

Have you had the Battery Sensor KH0 recall done
