I have same issue with mine. Apparently it's the latch and it's quite a common
problem on these.
All doors lock from the remote, but the driver's will not unlock. It opens from inside as it should etc. It's just a bit embarrassing when you stand there in the rain
What I found strange however is that after driving off the car locks itself. When you come to a stop and switch the engine off, put your window down and try to open the driver's door from outside, it works.
