Has anyone had issues with a weak battery in the Cupra Formentor e-Hybrid with a registration date of 03/2025?
The battery management seems to be functioning. When the charging cable is connected, the voltage is 13.1 V. While driving, the 12 V battery is charged with 14 ... 15 V.
When the vehicle is then parked, the voltage drops to 12.3 V. Within 2 days, the voltage then decreases to 11.6 ... 11.4 V. When opening using the button on the remote key, the voltage then collapses to about 10.7 V. Opening via KeylessGo has already been deactivated. Sometimes, configuration data needs to be reloaded according to the infotainment system.
I don't believe this is caused by a consumer with too high a standby current, as charging with a CTK charger indicates full after 2 ... 3 hours
What is your opinion? This should definitely still be covered under warranty for a 15-month-old vehicle, right? Are there any corresponding experiences?
