My CR-V went in for it's 4 year service and 3 days later I drove it, parked up did some shopping for an hour and came out and it wouldnt start.  I called my breakdown company and they came out and it started straight away.  The same thing happened last week, called the breakdown and they jump started it.  it was fine, ran it for few hours but the next morning it wouldn't start.  Charger said it was at 50% so charged to 100%, the next day it failed to start.  Recharged battery, disconnected it from the car and left it overnight.  Reconnected it back up and it started.  Does anyone know anything about this type of problem in the 2017 CR-V iDTec please?  I'm having to take it to Honda shortly and I don't think this is the sort of fault that should happen after 4 years and only 27,000 on the clock.  In the US there is a service bulletin that covers this fault but i can't seem to find one in the uk.  Any advice totally appreciated.

Many thanks

The battery should be in perfect charge condition at all times for the vehicle to function correctly.

If the car hasn't been used much (especially if only used for short journeys) during lockdown periods then the battery will deteriorate and lead to sulphation.

It could probably be reconditioned using a special battery conditioner (much like a battery charger) which will desulphate the battery and return it to almost original condition
