My 2005 MDX would vibrate/shudder/grind while accelerating between 35 to 40 mph. When I took it into the dealer, I was told they could not reproduce the problem. I had 30,000 miles on the car and was in the last month of my warranty. The noise continued to become more frequent and more noticable. I took it back 12 months after my warranty expired and presented hundreds of reports of the exact same problem taken from the internet. I also presented a service bulletin from Acura (06-003 dated June 9,2007) for model years 2003 & 2004. After opening a case with Honda America, many calls and many threats, I finally got them to agree to 100% coverage of a torque converter replacement ($2,000). From my research, I have found hundreds of reported cases of this exact same problem for model years 2002 through 2007 for both Honda Pilots and Acura MDS's. FYI
