Water Pump problems of the 2007 Nissan Altima Hybrid

My hybrid warning light came on and the car started to lose power on the highway. The dealer told me that the hybrid water pump had failed. Niacin did not have their own hybrid technology in 2007 so the hybrid system is from Toyota. Toyota has recalled the hybrid water pumps for that model year because of failures. When I told the dealer niacin of bourne in massachusetts about the issue and faxed him the information on the recall I asked him to contact niacin about the issue. He stated there where no currents recalls on the part and refused to inform niacin. I asked twice if he read the information I faxed he said they received it and he had not, he told me to call 1-800-nissan1. When I picked up the car I asked for the parts and was told that because I did not ask for the part in advance that they were thrown away. I called on niacin corp on November 15 and was told I would receive a call back by the end of business on November 16. I called two more times as of 1:25 pm 11/20/2012 no one has called me back. I believe that this may represent a significant safety issue in regards to the niacin Altima Hybrids since no one from niacin called me back I feel I have to filed this complaint.
