Hi and welcome Suzy.
Well you must be the only one who likes it
I switch it off every journey. I hate it.
First of all start stop only works in certain conditions, read this...
If you find the start stop is not working at all, then its a visit to the dealers, to sort it out.
Now let me give you good reasons why never to use start stop.
1....It gives a little saving on fuel.
1...It causes engine and component wear due to many start stops in one journey
2...It can cause decrease of battery life (2 or 3 years instead of over 7 years)
3..The danger of being in a dangerous situation where you have the engine off, (traffic lights and junctions) and that delay in starting and getting out of there, can be life or death
4...Accidental operation of start stop in middle of junction or nose of car sticking out, again can be very dangerous, seen it happen many times to the embarrassment of the driver, though embarrassment is better than getting hurt or death
To me it is too dangerous in a car, and should never have been legislated.
