I have 63,826 miles on my 2018 kia Optima s and I drove it to the store and all my light on the dash came on when I would come to a stop and my power steering would go out and about cause me to wreck. I was told that it was my alternator but after getting a new alternator I then drove it to get dinner a few days later when the same thing started happening again and my power steering kept going out again. I have two newborn babies, a 5 year old and a 10 year old in the vehicle with me and had I wrecked when the power steering went out it could have been a bad situation.
