I have a 2014 Ford Focus (base model, no extras at all).
Here’s what’s going on: the ABS, traction control, and brake lights are on, the electric power steering isn’t working, and neither is the speedometer.
Here’s what I’ve tried: I used a code reader and it gave me a low battery voltage code. I replaced the battery, swapped out a corroded positive wire, and cleaned the connections. No changes at all.
One weird thing though—if I let the car idle for more than an hour, everything seems to work fine.

Maybe check your fuses? I noticed a lot of accessories share the same fuse.
Which fuses should I start with? Not sure where to begin.
Start with the high-amp fuses in the battery case. Just follow the positive cable—you’ll find about 8 fuses, usually 50-100 amps. No need to swap the 150-amp one, but the others can cause issues even if they look fine. Swapping all of them shouldn’t cost more than $20. Oh, and remember to disconnect the negative cable before swapping high-voltage fuses!
Honestly, you might want to take it to a mechanic for a diagnostic. It could be a bunch of things, and trial-and-error part swapping can end up costing way more. Just make sure you go to someone reputable and not a backyard mechanic—they might make it worse.
Have you had any brake work done recently? I had a similar issue once because I forgot to plug the wire back into the hub after working on my brakes. No power steering, ABS, or traction control until I fixed it. Worth double-checking if you’ve had any brake work done!
