Assuming the tyre pressures are all correct! this is quite normal for front wheel drive cars, as one drive shaft is longer than the other, the shorter one (in your case the left) is more resistant to the torque of the engine(stiffer) and the right being longer will tend to twist more, so the left wheel will accelerate before the right so causing the car to pull to the right, this is known as "torque steer"
