for some strange reason when i drive at times my abs light comes on and the traction control light starts to blink and my car slows down like it wants to shut off or something......everytime it happens i lose power on the highway...what is causing this?

 

I never experienced that on the highway. I've had it happen in snow when I start fast or deliberately drift around a corner --the ABS light starts blinking on the display until the car regains 4-wheel traction. That just tells me one or more wheels were slipping and the stability control kicked in.

 

Turn off your traction control an see if the condition continues.

If your not slippin and slidin it could be a sensor or module problem.

If you have a Q with different size tires you might be confusing the computer.

 

Brake light switch is the most likely cause. See this post... https://www.audiforums.com/m_787210/tm.htm
