Hi,

I believe that the fault all comes down to the stop start system. My dealership had the car because I originally took it in as I had a problem when going down the gears or pulling away from first or second gear. My car has the CVT box fitted so I felt the car was pulling away and juddering. It was explained that the senior mechanic felt it was the stop start shutting down and re starting when it didn’t need to ?? New battery has been fitted and software cleared. So far so good. Car has only just completed 2000 miles

Just had this fault this morning, along with a stop/start error. QQ J12 1.3 mild hybrid tekna 4wd xtronic
Out temp -1 C or 30 F
8,800 miles (14,160 km)
Mainly motorway miles
Still there on restart but not showing any faults on connect app

UPDATE:
Car with Nissan, lithium hybrid battery pack needs replacement. I’ll update when it’s returned, I’m a little concerned that other posts say the cars not safe to drive while Nissan told me, it’s only amber warning, you can keep using the car!

Had this fault pop up 2 weeks ago and dealership said it’s common and with some more driving it should sort itself out (was at 900 miles) . Was still there a week later so took it in last week and Nissan did a battery health test and said it needed a new battery so to wait an hour. They fitted a new battery and the fault was still there so they said it had to be taken back in the following week for them to do some investigative work. Was taken in this morning and just received a phone call saying the lithium battery is faulty and isn’t safe/reliable to drive so will take a few weeks for the repair. This is the first time I’ve had a Nissan so a little worrying with only 1200 miles on the clock, only had the car for 8 weeks.

Just got both battery management and stop start warning up on 2021 J12 with 18k on the clock, been sat for a couple of days in cold but car battery showing 14.5 v on my test, will be going in Monday, changed car from J11 recently after constant problems, paint job, gearbox replacement, condenser replacement, door window regulator loose, seems another 8k wasted

They said they have changed the 48v battery under the driver's seat and the 12 v battery, the one under the bonnet hasn't been changed so where is this other 12v battery? It's not in the boot as far as I can see only plastic tray for puncture etc
