Power Steering Failed problems of the 2007 Lexus RX350

Noticed issue with power steering while turning on my 2007 Lexus RX-350. Vehicle inspected by technician and was informed of the power steering failure , oil leak. No dropping of oil was noticed on the parking floor at my home. Technician informed that the oil reservoir was almost empty and the oil was collected in a boot under the steering rack. If the oil dripped on the floor, I could have noticed it and fix the issue much earlier. Luckily I was not driving on the freeway at highway speeds? running without oil in the power steering? based on my discussion with Lexus technician one in every three RX-350 2006 - 2008 seem to have this issue within 5 years of in service date and Toyota/ Lexus seem to pay no concern for the safety of the owners. Please review and advise all owners of this failure and ensure Lexus recalls and fix this issue for all owners. This vehicle is now in toronto / canada.
