Power Steering Light On problems of the 2009 Nissan Murano

Was at lowes with my grand daughter when the steering wheel was locked and the steering lock indicator light was on. Vehicle would not start due to the malfunction of the steering lock box. Weather was bad and a gentleman tried assisting me but to no avail. After looking at the indicator lights he informed me he had heard of this issue and the problem was in fact due to a faulty steering lock box. I had no choice but have the vehicle towed to my temporary home and here it sits. My home flooded with 7' of water mid August and is still uninhabitable. I'm a grandmother with limited funds and really cannot afford to spend the large sum of money required to pay for a known defective part. During my research I found out that Nissan knowing this issue has now imited the warranty time on this known problem. I thank god this occurred in a populated area where assistance was readily available and not rural as I quite often find myself traveling to these areas. Is this a safety issue? absolutely!! Nissan should be ashamed knowning this part is defective and refuses to do a mandatory recall. Any assistance would be greatly appreciated in this matter. Thanking you in advance.
