Gas Recirculation Valve (egr Valve) problems of the 2011 Nissan Rogue

Coming home from long (06/2013) trip; high volume traffic highway car started vibrating & would not accelerate with no warning lights. It would not pick up speed and it slowed down, stalling drastically & pulled aside to turned car off and let the car cool but the car would not turn back on. The windows and radio would work but the engine would stall and not turn on. Waited 20 min the car turned on again. Reported the problem to Nissan service & they stated the brake switch need replacement; was replaced. On (11/13) & coming home the issued started again. The engine vibrated, stalled, & not accelerate. Reported to Nissan service and they found no issues. Third, time 07/2014 same issue service looked at the car; found a service bulletin stating 08-12 Rogues have cvt failure when driving 65 mph and higher, temp of 96 degree or higher; climbing steep or extended hills for 6 or more miles, & whine or rattle noise reducing engine performance. Told the part would be ordered; after 2 weeks service stated part is back order and not sure when will be in. I reported to corp & they stated the part is not available due to back order til the end of September 2014. Told Nissan I fear for my life & family when taking long drives & been renting car; if they would reimburse or provide another vehicle while the part comes in they stated no they do not reimburse or provide rental. How can Nissan know about this issue and risk the lives of family. Are they waiting for something massive and dangerous to happen before they take action! I am paying for a unsafe care while Nissan is aware of the problem & is not taking proper action. We have daily responsibility to do & driving unsafe car is scary! Nissan fast to call of payments a miss one but they are not fast to fix this dangerous issues! people who have Rogues needs to be aware of this problem & Nissan needs to recall this part.
