Yes.
While the vector for velocity is north, acceleration can point South if the object is decelerating (accelerating in the negative direction).

Acceleration is the first derivative in time of velocity.
If the car is de-accelerating to the north, it can be viewed mathematically as positively accelerating towards the south.
Eventually, if the acceleration continues, the car will slow to zero velocity towards the north and then back up at the same acceleration to the south.

If it is breaking, i.e. has a negative acceleration towards the North, it must have a positive acceleration towards the South

If the driver was going north and reached a velocity to north and then slammed the car into reverse. It would then be accelerating in a southern direction and losing its northern velocity. Till that northern velocity is gone it would pass your north-south test.

Sure if its speed is going down (breaking) it's accelerating toward the south.

yes
If it puts it's brakes on and still continues to go in a straight line north (i.e. it is braking) then the acceleration it experiences will have a positive component to the south and its velocity will reduce.

yes...in the end the automobile is going to stop... it's the same case when you press the breaks

In see you are a ford owner too.
