My car is stalling, shaking, shuddering, not accelerating and downshifting while I am on the highway almost killing me while attempting to inch my way across the lanes to the shoulder. With NO WARNING my vehicle completely broke down with my children in the car one is Non Verbal and on the Autism Spectrum with a serious heart condition- I myself am clinically diagnosed with PTSD and the terror I have experienced is absolutely devastating! I have made multiple calls with no help and no assistance whatsoever!
