Default Dash Lights Keep Coming On

My ABS, Brake, VSC and Trac Off, light keeps coming on randomly. It happens while I am driving.

Is it something I can fix, or is it something serious, that I need to take it to the dealer? It seems to be happening more often lately.

I would be willing to guess it it your brake light switch that is located above the brake pedal. It is a common problem. You could DIY and if it proves too difficult go to a shop.

There is a TSB on this. If under warranty, Lexus will resolve it. If not, somebody here has done a DIY. The part is $25 but access to it is not easy. Good luck.

I took a video of this as it happened twice on my car. I have an appointment next month and will have them look into this.

What/where is the TSB on this? I'd like to give them this info so they know what to do as I doubt it'll happen while at the dealership.

They would know. Just like you I took pics of the lights. They came back quickly, it was the brake switch. Luckily I had extended warranty and my deductible was zero.

Yeah my car is still under warranty so I'm good. Thanks I'll mention the brake switch as a possible fault.
