My Nissan Tiida occasionally stalls for about 2 seconds when I release my foot from the brake, and it also stalls for 2 seconds when I accelerate before returning to normal.

Hissing noise out of brake pedal. Main garage said new brake kit to solve problem. Also oil leaking into the turbo affects acceleration

My Nissan tiida latio shows hand brake on on dashboard although handbrake released what can be the problem

My nissan tiida is giving me a lot of problems,the reverse is not powering,its showing a 4wd and hand brake when i am traveling long distances.
What could be the problem?
