I was driving my Nissan qashqai tekna J11 2015 around at low speed and suddenly these warnings appeared! What's the problem?!

I had Start and Off (no other warnings) issue going for the last few month as the battery went low voltage since my car has been parked for long times however I got a new battery last month and the issue was fixed.

Your help is much appreciated!

To me it would suggest a battery issue... perhaps it's not charging properly.

BCM clearly don't like the front radar sensor input for one hence the Chassis fault.

You can see what the battery behaviour is like in the Hidden Service Menu.

Guess what, I just checked my car and all the warnings just disappeared and everything is back to normal! WHAT IS GOING ON NISSAN

The battery is about 1 month old Varta E39 AGM

Here's the stats from hidden menu:

***Illumination signal 0% is probably that my car has the cover on so all cameras and covered.***

Sometimes you should drive with that screen selected. You will then see the alternator charging between 13 and 14 or so volts

I did drive with the screen selected and it shows about 14.75

Thats a good charging voltage. If you do multiple short journeys with Stop/Start you will likely undercharge the Battery. It needs at least 45 minute runs fairly often so the Battery can charge correctly. You should see the Battery charge volts fall from 14.75 to 13.2 or similar as the Battery charges.

Do you mean that 14.75 means the battery is charging and when it falls to about 13.2 the battery is then charged?
