J12 Start stop power surge

[eppiedutch]

Hi Proc, like mentioned in prior posts, you can prevent this behavior from happening by just pressing the start-stop button once (hence deactivating the start-stop mechanism) at the start of every journey.
In the Netherlands this button is located to the left of the steering wheel (next to the lane assist button), but I don't know if these buttons are located similarly in UK models.

Of course this is only a manual workaround, but as long as Nissan / my local car dealership hasn't fixed this issue, it's only a minor inconvenience to do this.

I agree with you the car is otherwise very nice to drive!

Some models are equipped with a lithium-ion battery to regenerate more energy when decelerating.
These vehicles will begin idling stop during the deceleration and extend the idling stop time.

More on the topic here as well: https://europe.nissannews.com/en-GB/rel ... erformance

When decelerating, energy is recovered through regeneration and stored in the Lithium-ion battery.
This charged energy is then supplied during Idling Stop, Coasting Stop (Xtronic versions only) and Torque Assist.

When coasting to a stop, at speeds of less than 18kph, and `brake on', the engine will switch off and the stored energy is used to power the vehicle's electrical equipment.
This allows engine stop to be extended and fuel consumption lowered as a result.

After reading this I would say that this is a feature and not a problem. But again during that almost stop case (I don't full stop at the end but continue to drive) when it does shutdown the engine if I depress the break pedal I would expect in that second when the engine starts again (after it realises that I'm not doing full stop) that the car does same magic as with auto hold to prevent car from jumping and excellently hitting something in front.

Glad I found this thread after a search, have encountered the same surging issue on our 22 plate auto.
Car was in the dealers last week for this, and a couple of other issues, master tech informed us that there wasn't an issue with the gearbox, although receptionist did let slip it was a known feature.
A reset was applied to the car and we had it back, although it's due to return for them to have it for a week for a intermittent heater motor issue, and we drove home, and it did indeed seem better, but we have now realised the stop start does not work, and although turned on in the settings, the dash icon has a line through it stating the system is off, so I'm wondering if they actually carried out a update, as mentioned by others on this thread, and it's not applied correctly .
If it's still not working by the time the car goes back, we will obviously mention this, but it's annoying for it to go in for one problem, and come out with another.

Hi,
I have the same issue for my J12.
I bought it November’22 and I think that all related software should be up to date.
I asked a dealer when I went for 1.000 km control they said that this is known issue but not have a fix for this yet.

Then I guess first one to get (hopefully a software fix) will let us know here so we can instruct our dealers on what to do.

Any update from anyone?

It needs to beconfirmed if this is only happening on e-Power models or normal ICE varients.

Not experienced tis on my e-Power.

Not experienced tis on my e-Power.

It happens on my 1.3 160bhp CVT J12
It also happened on my 1.3 160bhp DCT J11B
Never driven an e-power but the drive trains are quite different so I suspect that it won’t occur on an e-power
