On 3/21/2021 I was driving on the freeway for about 25 miles, when my 2003 chevy Impala started making a whining noise and it continued to get worse with each turn. My husband soon realized it had to be the power steering fluid. So he put a bottle of power steering fluid in and after starting and driving for a few minutes the car was back to normal! so I proceeded to get back on the freeway to head home. As soon as we got to our exit about 23 miles from where we had just put the fluid in. It started making the same whining noise. So back to the store for more power steering fluid. He fills it up. The next morning same problems. We know now there is a leak in our power steering but not sure where exactly. My car now sits as we can't afford to be adding bottle after bottle of power steering fluid to my car everytime we need to go somewhere. My husband believes we have run into the same issues that have recently been reported by NHTSA id# 11316116 being power steering return hose rubs against some part of the motor and rubber hole in power steering return hose.
