I may have had this issue or it may have been me as I am a very new user of Ev's.
On one occasion I was parked up, switched on pushed the brake pedal down whilst switching on, waited for Ready. At that moment I may have lifted my foot slightly from the brake pedal before selecting Drive but a message came up saying something on the lines of 'shift out of park'. I tried several times eventually it went into drive.
Happened again this morning, once, but then worked.
I put these both down to user error.
Can you run through exactly what happens as you try to put the car into Drive, as that will help me if it happens again?
