Did You Have A 2 Or 4 Wheel Alignment?
You probably had a front wheel alignment. The steering wheel should have been held in a centered position during the alignment. If this was done and both alignments were properly done, the problem could be caused by one or more faulty tires. Tires will sometimes cause a vehicle to pull and the driver must turn to compensate and go straight. Swapping tires from right to left to see if the steering wheel centers or goes off center in the other direction might tell if it’s tires. It’s also possible that the rear wheel alignment might be off. A 4 wheel alignment might be in order. Also, check the vehicle carefully for dragging brakes or wheels.
