Engine Rattling And Whining Sounds problems of the 2006 Acura MDX

On January 14, 2014 my daughter took our 2006 Mdx to the dealer for mechanical evaluation. The car has been hesitating while driving, trying to stop the car while driving. The diagnose came back with the following: transmission needs to be replaced and engine mounts have to be replaced as well for the total of around $7,200. In October 2008 (mileage 55k) the original transmission has been replaced with a re-manufactured part. December 2009 original symptoms (whining noise, shutter at 40-50 mph) have reoccurred and have been reported to dealer's mechanics. They could not see any problems. December 2010 whining noise started coming back again. Dealer's mechanics could not find anything wrong. Now we are faced with a transmission that is malfunctioning plus engine mounts have to be replaced. In speaking with Acura's customer care I was informed that the transmission replaced in 2008 was not an authentic Acura part. I kept insisting on more in depth explanation but did not receive any. It is my understanding that improperly working transmission causes damage to engine mounts. It seems Acura dealer's mechanics have somewhathow missed it. Acura is not willing to take responsibility for any of their omissions. Now the car is no longer under warranty. All of described instances are a huge safety hazard. Putting in non-authentic parts under the label of warranty is a fraudulent step. All services have been performed at jerry damson Honda dealership in huntsville, alabama. I would like a formal investigation. In addition I feel that dealership's mechanics should go through additional training to avoid future misdiagnoses and a reduce danger to consumers.
