All cars have problems these days with the amount of electrics and sensors in them.even if it had 7yr warranty you would still be in the same situation running back and fourth to the dealer. I've been lucky with my 8yr old qashqai clocked up 80,000 miles in the 5yrs of owening it never had a problem...

only other way around it is to find another dealer that may not be local but can get you seen quicker

V7 is the last ever maps card been released for the qashqai, the maps on it are from 1st half of 2021.

i would clear all the codes and check again in a wk or so and see if any re-appear, as you don`t know how old all them codes are

so if new batt is not getting the car started still then yes starter motor next, any good garage should be able to check that for you, did you fit the correct batt for your car

I always use a small independant local garage. To get your batt checked use kwick fit. Halfords etc. Once you know if the car batt is no good order it online and fit yourself £110

Tryca good brand of 2032 batt for the keyfob. They should last around a yr

Take a few mins normally with engine running

Any good garage should be able to test the condition without telling you that you need to replace this and that
