Wifes QQ EPower Tekna is less than a month old.
We went away for the Friday to Sunday leaving car at home.
Tried to go out in it today to find it totally unresponsive. Cant open with either of the keyfobs or the key. App says everything is fine with the car!!
Now waiting for RAC to attend and i presume get entry and charge the battery but i guess this will happen again if she doesnt use it.
Is this a known fault with these cars and if so, whats the cause and fix?
Dead car

Must have a significant drain on the battery, no way should battery be dead after 2 days. Anything connected to permanent live?
I've beed away for a week at a time and not had an issue with my e-power.

I regularly leave my car, 73 reg e-power Techna at airports for 2+ weeks and have had no such problems. I did buy a voltmeter/thermometer which plugs into the cigarette lighter and keep an eye on it. 14.4 volts after starting is common and on a run this tapers off to 13v or so.

The pop out mechanical key within the fob should always allow the door to be opened.
As commented on the other thread the cars are often delivered with the small 12 volt battery undercharged so with little reserve if the lights are left on or if the car is used in auxiliary position rather than READY position. This is not very clearly shown in the owners manual but it does warn that the battery will quickly discharge if the start button is pressed without simultaneously pressing the brake pedal. In my experience ( and advised in the manual ) the 12 volt battery should be charged after the car has stood unused for 28 days. This can be done either by leaving ( or driving ) the car while in READY mode for at least 30 minutes ( an hour is better in my experience ) or alternatively it can be charged through the positive terminal in the engine compartment fuse box.
In an emergency this positive terminal may be used to "jump start" the car but the instructions in the hand book should be carefully followed.
For completeness: If the car is to be stored for a longer period there is a master fuse/switch designed to be pulled out to isolate the 12 volt system completely. See page 456 of owners manual.

Update:
Diagnosed with a dead 12V battery that needed to be replaced as opposed to charged. I think the RAC mans word was "condemned" when describing the battery!
Finally got the car to the local dealer, who having carried out further diagnostics, replaced the 12V battery under warranty.
I've bought a jump start kit to keep in the car incase this ever happens again.

We used the car sparingly over Xmas and all seemed well.
Except on Monday, my wife went to get in and go to work and it was dead again. It was used on Saturday but not Sunday.
It was only on Wednesday that we managed to get the car to the local Nissan dealer. Needed to get the RAC out to jump start it and then follow her whilst she drove it to the local dealer.
Not impressed.

So you couldn't use the jump start kit?hab1966 wrote: ↑Mon Dec 16, 2024 10:03 am Update:

As suggested by Decccadick it is well worth buying a voltage display device which plugs in to the 12 volt socket in the centre console. If there is any fault with the cars charging system this will immediately show up because you won't see 14.4 volts when the car is running. This is the one I use https://www.ebay.co.uk/itm/156191349734.
Presumably if the car is new RAC services are provided by Nissan so won't cost you anything.

My new Epower Qashqai (10th December) has had 2 incidents of Dead Car 3rd Jan and 8th Jan.Both times called out RAC who diagnosed flat battery.Car now at dealers awaiting investigation who say they can't look at it for another week.
Not happy.

Once a battery, even a new one, goes completely flat it is vital to fully charge it immediately with a modern intelligent charger. This should take many hours if using a sensible charge rate. For example a 40 Amp.Hour battery could take 10 to 15 hours because charging it more quickly is not good for its longevity. A good charger will do this by varying the charging current and can even use recovery mode which pulses the charging if necessary.
This cannot be achieved during an RAC call out, so any responsible main dealer should either hold the car for a full day while charging or provide a new battery which they have charged fully. New batteries do come ready to use but not fully charged. Delaying this because of workshop schedules is completely unacceptable and means that many batteries will be written off unnecessarily.
If your battery becomes this flat you would need to drive, or at least leave the car in READY mode, for many hours to save it. As noted above the QQ charging system holds high voltage ( around 14.4 ) for about 30 minutes at the start of a journey before dropping back to 13+. This is ideal for good battery life and saving fuel, but does mean the battery will take longer to fully recover if completely discharged.
In the real world owners who only do short journeys or, like myself, sometimes do not use the car at all for a month or more, should connect up a charger once a month. It is most convenient to use the positive terminal in the engine compartment fuse box for this.
I would also advise that on delivery of a new car it is either driven for several hours as soon as possible or alternatively connected to a charger as described above. A properly maintained battery should last for 5 years but one that is allowed to remain discharged might only last for 2 years.
