Other Fuel System Pump problems of the 1999 Chrysler Sebring

Takata recall. I am having several issues with the whole braking system, as it is very difficult to pinpoint the exact cause of having no brakes. I have no type of brakes at all. When taken off parking, even with foot on brake, car will begin to move. This seems to be very common in these cars. The fuel pump was also replaced as it was letting less power go through. This happens as the car sits in parking, as well as, when driving. Also, the mechanic that looked at the car said that the pump needed to be replaced due to possible fire hazards. The lights flicker on and off by themselves, sometimes radio works, sometimes, lights get stuck on.
