I notice this on my left sliding door only and wonder if there is a software problem with the car. FYI, I made sure that the safety locks on both sliding doors are turned off and central locks are also off. Everytime I stopped the engine and try to open the door from outside the first time, it will never work on the driver side but passenger side is fine. However, after I open the door with remote or the button on the dash, then I can start to open the sliding door from outside. This annoys me a lot as I have a habit to get my baby by pulling the sliding door from outside. Since it only works on one side, I wonder if this is a software issue, anyone with 2011 model has the same issue?
