is it common to loos power steering on a new 2024 Honda odyssey in middle driving

Hello, I would say it's almost completely unlikely that this electric power steering would fail. Definitely consult a local dealership near you regarding your concern. And remember, unless you have over 36,000 miles already - or show evidence of damage not related to a defect - you have a warranty that covers defects. I would definitely encourage persistence at your local dealership to address your concern.
