My Nissan Altima 2011 when I drive and brake for pothole it will not pick sharp

What is your question?

It doesn't give any sign but any time it refuse to pick sharp I will switch off the engine and restart again it will pick sharp and normal

What makes this problem better or worse?

Anytime I drive and slow down

How long has your 2011 Nissan Altima had this problem?

For about two month
