Then what you first posted should actually work.

pawn Код:

//OnPlayerSpawn
SetTimerEx("GiveAllCar",12000,0,"d",playerid);

forward GiveAllCar(playerid);
public GiveAllCar(playerid)
{
    new Car, Float:X,Float:Y,Float:Z,Float:Angle;
    GetPlayerPos(playerid,X,Y,Z);
    GetPlayerFacingAngle(playerid,Angle);
    Car= CreateVehicle(411,X,Y,Z,Angle,1,-1,-1);
    PutPlayerInVehicle(playerid,Car,0);
    return 1;
}

What do you mean by ''sometimes'', does this appear after the server was online for a long time?
