Toyota Corolla 2024 Has Ongoing Vibration Issues and the Service Did Not Fix It

My 2024 Toyota Corolla has been running with vibrations for the past two weeks. It is noticeable at idle and at certain RPMs. I took it to the service center, where they performed wheel alignment and balancing. They told me that vibrations at idle are normal for a three-cylinder engine. However, there was no such issue two weeks ago. I can even feel the vibrations in my legs and abdominal area. The problem persists even after the alignment and balancing were done. I will never buy a Toyota again. I have confirmed that European-made cars and technology are the way to go. My previous car was a Renault, and I used it for 12 years without ever encountering such an issue.
