Just picked up my 2005 MDX from dealer after replacing the torque converter. It appears that the vibration/grinding between 35-40 mph has now been eliminated. For background, I reported this problem in March 2009, a couple of months prior to the expiration of my warranty. The service tech stated that he/she could not reproduce the noise I was hearing. Over a year later, the noise was now continuous. I took the vehicle in and this time the service tech could hear the noise. I was told that the vehicle was out of warranty (45,000 miles, but over 60 months) and that it would cost $2,000 to $3,000 to fix the problem. I opened up a case file with Honda America. After several calls, I was offered a repair for $500. I continued to complain and mentioned that I had uncovered over 100 complaints for the exact same issue. The Honda rep. still would not budge on the $500 cost to me. Finally, I mentioned that I might pursue a "class action suit". He said he would speak to the district supervisor. Miraculously, he came back and said that Honda America could cover 100% of the repair. I would suggest that anyone battling this issue out with Honda America mention "class action suit". There attitude seems to change quite significantly! Good luck!
