I was driving my car and suddenly it flashed across the screen service stabilitrak, then service traction control system, then reduced engine speed. This caused my vehicle to slow way down out of no where from 70 to less than 30, and made steering near impossible. I have my two children I drove around and I'm afraid to even drive because if there's an accident with them in the car because my cars slowing unexpectedly someone will be paying for this. This is a huge safety issue and I see all over it is and it needs to be fixed!.
