Normal? No. Either you have a battery that needs replacement or a more than normal current draw.

A low or flat battery will play havoc with the electronic systems on the car. You may need to either replace the battery, do a seat reset, or both. You may even need to have the faults read and reset or even replace the seat module.

Depends on how often the car has been used. they really do need to be left on a trickle charger.

When i collected mine from the owner the battery was dead, we got it started and from then on i have always had it on charge its the same battery from new.

Have a 2012 v12v roadster and frequently leave it off charge for much longer that 2 weeks, even 4 without starting it. Never a problem. Had it 2 years but no idea when battery was changed if ever.

Had exactly the same problem on mine a couple of weeks back.

Left off charge for a couple of weeks. Ended up having a flat battery. On trying to start it the electrics for the seats and windows stopped working.

It was the 20A fuse 84 & 85 had blown (check the manual) in the cabin fuse box. Behind the carpet in the passenger footwell.

Last weekend I put a new battery in aswell after the battery drain caused it to get stuck in gear. Hopefully it should behave itself now.
