Has anybody experienced problems with both their ABS and TCS/DSC warning lights staying on after start-up? Dealership checked the sensors/computer. They tell me it's a short in the line. Find short or replace harness. Now the cruise control is non-operational. I have a 2005 RX-8. Any thoughts?

 

Bounce over here and see if anything helps.
If it does, then report what it was in that thread, even if it's nothing I have noted there.

my 3 series would do that when the wheel speed sensor got dirty. doesn't hurt to check it out; try a free fix?

 

Mine recently started doing this only when I turn on my driving lights, have you heard of that? I'm so lost a to whats wrong

 

Do you have any led brake lights or an led 3rd brake light? I recently installed one and the car didnt like it. After returning to the oem 3rd the lights went away

 

^^ this.

If you replace your taillights and the third brake light with LED (without using a load resistor), this is what will happen.
