What's up with my car's stop-start?!

My start-stop doesn’t work then randomly when I’m driving the lights on the dash come on and the car loses power; do you know why?

Hi Tracy,

I'm afraid without knowing exactly which car you have, this is impossible to diagnose. You should bring the car to a good mechanic or auto-electrician.

There are many reasons for a stop-start system to not always work. Read this question and answer on that subject for instance.
