Power Steering Light On problems of the 2019 Toyota RAV4

Approximately 30 days after purchasing my 2019 Toyota rva4, while driving to work during the week of August 1,2019 on a major highway my vehicle swerved to the right almost hitting an 18 wheeler without me steering in that direction. It happened about 15 minutes later swerving again towards the right almost hitting a car. During the week of August 5,2019 the car did the same thing again. While driving home, this time the steering wheel warning light started flashing. I checked the owners manual and it stated to take the vehicle to the nearest Toyota dealership immediately which I did. On August 17th I brought my car in to be checked. Initially a young service manager told me there was nothing wrong with my car. I was persistent in having my car checked. After the young service manager spoke to a senior service manager, he suggested to the young manager that if I am being persistent then she needs to do a code diagnostics on the car. I was told an issue was found and they had to keep my car. On August 21,2019 I received a call stating my car was ready. I asked what was the problem. I was told the steering angle sensor had to be recalibrated. The car was tested for 14 miles with no problems, but I should keep an eye out for any other steering issues. I must say I am not comfortable driving a car with steering issues. It is still swerving on occasions,but not as severe.
