Just joined the forum to see if other Kuga 2021 drivers have experienced 12 v battery failures.        Wow thank goodness I am not alone in my abject misery thinking I was the only one in the Country with a 2021 Kuga which suffers with 12v battery failure.

The AA have been out 6 times to boost start me after first showing me how to get into a car with no power and the secret of key in the fob. I have learnt their secrets and now can get into the car fairly quickly use a battery charger on the battery terminals under the bonnet and when there is life in the battery enough to open the boot I resort to charging via the battery terminals. The AA taught me the secret of a small battery monitor connect to the battery terminals which will blue tooth to my phone and give me an indication of battery charge .   I have spent out on a Blue Smart Charger which has been worth the investment so I can monitor the state of charge.  As I am retired I do not need to rush off to work so can leave the battery on a long charge.

The leasing company agreed to authorise my local Ford dealer to fit a replacement battery under warranty last August 2022 I having received the car October 2021.

However the battery dies on a regular basis involving more charging. I would have thought all Ford dealers should be aware of the 12 volt battery failure nation wide and know how to rectify the problem. 
I have not been told about the computer updates or fixes that some modern cars need I have only been told by the AA to use the engine instead of the EV power so the battery gets some charge. Thought the idea of a Hybrid car was to use the car for short journeys and so save petrol but I tend to drive my car as though it was just Petrol driven.I even invested in a EV wall charger !
negotiations on going with my local dealer to look at the problem again. Unfortunately took a 4 year lease this time instead of 3 so will have to keep complaining as I now know I am not the only one who has the problem with an otherwise enjoyable car to drive.

You could also invest in a jump pack such as the GB40 if you do ever find the battery flat and need the car urgently.

I'm interested in the battery monitor that Bluetooth's to your phone.  Would you have a link to that?  

 

I don't have much knowledge of these particular hybrids, but I thought a PHEV should charge the 12v battery when running on battery power as well as engine power?  I wonder if anyone else can confirm that?  I do know that a few of the major EV's won't charge the 12v battery when charging the traction battery from the mains.  This is often what leaves them 'stranded' despite having the equivalent of a full tank.  This is a well known problem though, so I thought Ford would have corrected the programming for a car made in 2021.
