Under HARD acceleration I will get first my Brake light then if I am on it long enough the Traction light will come on. The Brake light comes off but the Traction light stays on till I cycle the ignition. It is not the brake fluid and I have changed my pads already. I am running Coupe wheels with 275 35 and 245 40. Does the code get stored so I can pull it from the ECU with a standard scanner? I am thinking the speed sensor or maybe the ABS sensors may be going out. Not sure and want to nail this down. If I drive around "normally" nothing but when I get on it they flicker and maybe the Traction stays on.
Thoughts?

 

I have this same issue. I am running anniversary 19" vert wheels (non-square). Same symptoms. I do need an alignment that I do know.

Brake fluid looks filled enough but I'll be doing brake upgrade soon so I didn't check it very well.

 

Gonna reinstall the OE front rotors and get some Pads. That may be throwing it off. Rear rotors and pads have been replaced already.

 

When my G did this upon hard accelleration, it was the rear brakes were at service level after replacement problem solved.

 

Brake light on hard accel is usually as simple as low brake fluid

 

I'm having this same issue right now, same exact symptoms. It's been going on for a bit and now it doesn't even have to be hard acceleration, just anything over 3000rpm seems to be about the magic number. I know my rear brakes need to be replaced so I'm siding with clovissimo as to it being the issue.

Glad I could chime in 4 months after the last reply
