Electrical Jack problems of the 2020 Kia Motor Telluride

About a week ago, my wife drove out to go shopping but returned within 5 mins due to a low pressure tire warning. The tire was very low and she parked the car in the garage. I removed the jack (which had never been used previously) and started to jack up the front passenger side where the flat was. I was showing the notches for positioning the jack to my wife and showing her how to properly jack up a vehicle. Bear in mind, I have rotated my tires and done maintenance and repairs on my cars/suvs, vans for over 30 years. I had the jack straight up in the correct position and on a perfectly flat garage floor and started to jack the car up. By this time the tire had deflated to such an extent that it had about an inch or two from the rim touching the ground. I had just gotten the vehicle up to normal ride height when the jack collapsed suddenly and the car came down. I've never seen anything like it and am just thankful that I wasn't in the process of trying to take the wheel off. I took a picture of the jack and there is a bow to the threaded rod but otherwise you can't see very much from the picture. When you turn the jack, you can easily see a significant wobble in the winding action. I can't image having to try and jack up a vehicle on the side of the road in less than ideal circumstances that I had in my garage. Scary to say the least.
