2020 Chevrolet Blazer steering problems

In 2 occasions my vehicle came to a complete stop and turned off on me. I was thinking it was a safety feature but after the 2nd time I was concerned. Took it to dealership and they found nothing wrong with it. On another occasion I was leaving my house when my steering wheel got super hard and made it very difficult for me to turn the wheel. Took it to dealership and they found nothing wrong, according to them truck was perfectly fine.
