2015 Hyundai Tucson - Drives like it has a flat

When I turn a corner left or right the car rides like it has a flat tire.

My wife drives a 2016 and it doesn’t do that. To begin, I’d make sure the tires were properly inflated and that they had adequate tread. From there, the vehicle might need an alignment. It could also be a steering or suspension problem. If putting air in the tires doesn’t do it a good independent shop that specializes in alignment can tell you what you need.
