OnPlayerEnterVehicle gets called when a player is close to a vehicle and presses enter, it will never get called when a player is in a vehicle.
In your case, you'd need OnPlayerStateChange.

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if (newstate == PLAYER_STATE_DRIVER || PLAYER_STATE_PASSENGER && oldstate == PLAYER_STATE_ONFOOT) 
    {
        if (GetVehicleModel(GetPlayerVehicleID(playerid) == vehicle model) 
        {
             // do something
        }
        // ...
    }
    return 1;
}
