I am sure I read some where there are many factors to when and why it comes on or not, not sure what they all were now
Just booked car in for Battery Test on 3rd of Jan, they tried to give me multiple reason for the stop start not kicking in,all I do agree can effect if it kicks in but when I am telling them it really does not come on at all there must be a problem.

I had a whole detailed A4 printed page of reasons why Stop/Start wouldn't activate - but it was wrong!

Unfortunately I appear never to have scanned it and seem to have handed over as part of the service record when I sold the car.

Does anyone else have a copy?

I understand what you mean, where did you get it from in the first place ?

It was given to my by the dealer in an ineffective attempt to demonstrate that my car wasn't faulty.

Thanks for the reply all. I have got to grips with it now, and to be honest it's not amazingly designed. Seems to work as long as the heater etc is not active...bit of a pain!

Also had some issues starting the car over the last few days (cold weather) and have had to jump it a few times. I rang the dealer and they have replaced the battery, but its not been overly cold since so we'll see how it goes I guess.

So just thought I would update as I mentioned My stop start does not stop start.
Took car to Main stealer today and they did a full check of Battery and Stop Start system end result was Battery is no good and needed replacing.
Apparently this can not be done under warranty so wanted £120.

Told them to leave it I will ring Nissan, not even got off the forecourt and service Manager rings me to explain they are going to collect a new battery from another branch and If I return at 1pm they will fit it No Cost FREE.

So not sure why its FREE now but it is so Happy with that result.
I do feel it was all a little strange and can not understand who is going to front the cost of the Battery even if it is just the cost price

So as I was told in this post if your Stop start does not kick in then it may be battery.

Was there not a problem with Qashqai Batteries in the past ?

Terry, indeed this was a problem in the past with mainly Fiamm batteries see attached for example. But if you have time just go into “Search”and take a read - Dave 😉
