Appreciate all the responses. Perhaps I should just trust the software and adapt to using it until it becomes the norm.

Personally, I don't even think about stop/start. The only time I notice it is when there are circumstances that stop it from working. I find it odd sat at traffic lights with the engine running.

I wish I could get my stop/start to work, it only worked for the first month of ownership, dealership has looked at it twice but couldn't find a problem.

My stop/start was not working ( picked up on my 3 month check by the dealership but I hadn’t noticed). They ordered a new battery from Sweden. During the wait for the part to come in, it started to work. When I went back they didn’t fit the battery as it wasn’t required. It has been ok except for yesterday. It didn’t function once on a 26 mile round trip. I’m going on the same trip tomorrow so I will check again. The criteria for the stop/start function to operate depends on so much - see list.

Mine does not work either. The only time it did activate was after a 150 mile trip which seemed to be enough to charge the secondary battery up. But the next day it did not work again. Si I think the battery is only charging very slowly and then not holding the charge.

The thing is do I want it fixed or not?

I had an issue last year when the starter motor battery condition sensor failed. This stopped the stop/ start system from working.
The sensor was replaced very quickly and I’ve not had any problems since.
I would agree with Bobs comments above that I don’t usually give it a second thought.

What is the difference between driving in Eco and Dynamic?

My last car was a Nissan Qashquai and after 2 years the battery went. When the RAC came to change my battery he said it’s down to the stop/start button as it’s unusual to need a battery after only 2 years.

Since then I have always turned off the stop/start button but I’m not sure if I should really.

Eco saves fuel at the expense of performance. Dynamic give performance at the expense of fuel consumption.

Dynamic changes the auto gear box so that it holds onto a lower gear, eco does the opposite.
There are other differences that a quick search of the Volvo site will elaborate on.

Thank you Thunder grey. I only got my new XC40 at the beginning of lockdown so haven’t driven it very much.
Stay well xx

So today, stop/start functioned within a few miles. Bizarre.
Obviously some criteria had bet met today that wasn’t met on the last time I used the car - exactly the same journey.
