If the cable is at a slight angle, it may be hard to pull out after a charge and it’s easy to think that it has become stuck.
Ensure the charging connector and cable are straight and give it a firm pull. If this fails to work, many cars have an emergency release function which makes it possible to release the cable.
If both approaches fail, call the customer service hotline on 0800 240 42 42 and an agent can remotely request the charger to release.
