Nissan Qashqai 2019 system fault advice

aine kilbride

New Qashqai 2019 on dash message showed recently

Stop/Start
System fault
and then the white Auto logo beside the milage is flashing.

I called Nissan and they said the car was safe just bring it in for a diagnostic to wipe that message.

I am surprised. It is not yet three months old. What caused this and should I be worried about it?

Thanks. by the way, I know little about cars.

Could it be a low battery causing it? Does the car get much useage? Any recent event that might have drained it like leaving lights or radio on with engine not running?

Thanks for reply. No if anything it is not used much at all as of yet. The emergency people (who i was forwarded to) said it was not a major problem at all but to bring it in for test.

Am disappointed with this. I don't like all this bloody technology really. It's unsettling.

Well not being used much at all could be reasoning behind the fault, doing low mileage where the actual journey is not enough to recharge the battery power that is used to start the car, power the lights etc will run it down. Have heard similar faults before on other cars where low battery causes the start/stop to fail.

It’s a sign of a battery on the way out. The fault is indicating that the stop / start is disabled. The car Ecu won’t let the stop / start engage as it is not sure whether the battery has sufficient juice for the car to restart when it stops at traffic lights etc.

I had this on my own J11 QQ. New battery sorted it. As your car is so new I’d insist on a new battery under warranty. They’ll most likely try fob you off that they have cleared the fault when you bring it in.

Battery could be a dud or was lying up for a while before the car was delivered to you.

Hope this helps

Thanks. What about if I increase mileage immediately? Would that improve the situation?

It’s a known fault with the ‘FIAMM’ batteries. Had this happen a friend in a 181 . Car cut out at lights . The dealer replaced the battery under warranty

You could try it and see does it sort out the problem. My issue was intermittent at first and then the message came up regularly eventhough I was driving plenty with good motorway runs. The message would go away by itself, stop/start would work for awhile and then come back again with the fault.

You could drop by your local motor factors and they could test the battery for you before you go to the garage. That way you’ll know either way if it’s the battery.

They should remove this feature from cars IMO. It is not good for batteries or starters.

There’s upgraded batteries in cars with stop start. This issue is only happening due to a manufacturing fault in some of the particular brand of battery Nissan used.

Not just happening in Nissan cars. I have heard of similar problems happening in other brands with relatively new batteries causing similar problems particularly when the car only does city driving and short journies.

It’s a pointless feature IMO and is not good for any engine or starter motor to be constantly stopping and starting.

Hope you get sorted OP.

Agree that it’s pointless. I’ve mine permanently switched off.

Sounds like a battery problem, have seen it on a few Renaults. The car could have been build in early 18 and been sitting up before been delivered to the dealer. We were advised to charge and test the battery in every new car before the customer collects it

I would love to turn mine off permanently, but I was told I couldn’t. Did you need a garage to reprogramme the ecu or could you disable it yourself?

A guy who was handy with a laptop did it for me (on a bmw). The best €50 I ever spent. It can be programmed into a lot of cars.

Thank you all for your responses.

I just want to be clear about something as I am not very car savvy at all.

I have always have the auto stop button on. When I come to lights I stop the green hold light comes on. But then other times when I come to lights and stop the green light comes on and the car would switch itself off. I have never been quite sure why it was in hold position and other times it would switch off. I assumed it was the speed with which I released the clutch or something like that. I don't know.

But in any event my query now is this. What if I now turn off the auto stop button and just leave it off? If I stop at a hill do I pull up the P brake button to act as the old handbrake and then press the brake and P button to release it?
I just wish I had the old handbrake!
Thanks

Thanks. I’ll look around and see can I locate someone similar to do mine. Fully agree, well worth 50 euro to get rid of the annoyance.

The problem with switching off the stop / start as you mention is that it is resetted every time you physically restart the engine. You could in theory press the off button each time to disable the stop / start but that’s a pain IMO.

The auto hold should not be affected by disabling the stop / start manually but you’d have to check yourself. It should function as normal and auto release when you move off

I'm pretty sure cars with start stop systems generally have more robust parts to make up for increased starts. Deep cell battery will disable start stop if the charge is too low to prevent the car dying.

Your engine doesn't need to be on when you're in the middle of traffic. It will restart automatically if the engine isn't up to temp, windows fog up or the cabin temperature isn't met.
