NHTSA Complaint #11462368 — 2019 TOYOTA YARIS

I got new tires and took the car for an alignment. I am constantly having to slightly correct my steering wheel. One to three degrees to the left and right at any speed the entire time I am driving. It was setup for the diagnostic test and the technician came back in less than five minutes. To tell me that there is nothing wrong with my alignment and everything was at factory spec. So I told him to drive it and tell me that there is nothing wrong with my car. He came back looking shocked and said that was weird. Like driving on wet glass. So he started to ask me questions. My answers to the question were. I am the original owner, never been in an accident with the car or hit debris of any kind. Tires are brand new, no check engine or warning lights. Diagnostic scanner to the OBD port came back with no problems. Car had 25,000 miles on it at the time. I've been told it could be any of eight or nine problems or a combination of a few. Electric power steering, traction control, ABS, Tire pressure monitor, steering angle sensor, tie rod, ball joints, suspension. My question is, how does this happen with regular service and no warning detection system on board or service equipment finding anything ???
