Lexus UX Brake Light Failure

Hey, I've got a weird brake light issue with my 2023 Lexus UX gasoline. 242314 km on the clock. I'm getting a brake light failure and an error message. OBD-II shows an error stored. I'm thinking it might be the brake light switch. Anyone seen this before?

I had something similar on my UX recently. Is it happening all the time, or just now and then? Have you had a look at the brake pedal return spring? A weak spring can sometimes act like a bad switch.

Thanks! It's happening consistently. I didn't think about the return spring. What fixed it for you?

Mine was the switch itself. Like a light switch wearing out in your house. If you're comfortable, test the switch with a multimeter. Otherwise, a shop might be the way to go. Good luck!

Thanks for the confirmation and the advice. Turns out it was the brake light switch, but because I messed up installing aftermarket floor mats. They stopped the brake pedal from fully returning. No money spent, just removed the obstruction. Thanks again!
