general problems of the 2007 Infiniti M35

During the town driving car lost complete power. All the light on dash board including "mil" light came on. As a result I had to get emergency repairs costing $ 600. I also took car to dealership where to reprogram throttle position sensor cost me over $120. 00. Two weeks later I get notice from infinity that this a known issue and they will come up with solution for this problem. To this date I have not heard anything for either reimbursement or a fix. .
