Time and again problems with unlocking the power cable on the vehicle side

I always have problems with the charging socket on the side of the vehicle. Normally the KFz unlocks the plug when I open the vehicle. Recently, however, the problems pile up. Charging is finished and I want to pull the plug, which does not work. Most of the time I have to connect everything again, lock the vehicle and then open it again, so that the plug is released. A bit annoying, if you have to try 4-6 x to finally pull the cable out of the can. According to my friend, an entry was stored in the error memory (misfunction at the unlocking). On 10.10.2022 I have appointment for precise diagnosis. I am curious what comes out of it. Vehicle is now 1 year and 3 months old (kilometer 16xxx) and I have warranty.
