What owners wrote

A loud "droning" sound comes out at 2,000-2,200 MPH, especially loud at approximately 40-45 MPH. Dealership and manufacturer say that this is a "natural sound" of the 2004 mdx. I do not buy this explanation it is hard to believe that an expensive SUV such as this would have a "natural sound" like this loud droning sound. It is very loud especially during cold weather. They insist that this is related to the new dual exhaust system of the 2004 mdx. What if it is engine or transmission related?

Reported at 50 miles, November 2003

Reproducibly at automatic transmission shifting speeds between 20-25MPH, 30-35MPH and 40-45MPH there is an audible and palpable shudder as the transmission hesitates prior to shifting. Have brought vehicle to acura dealer 3 times over the past 5 years, every time stating the same complaint, and every time referencing a convincing multitude of acura mdx owners noting a similar problem. Every time acura service states they could not reproduce the problem and nothing is wrong with the vehicle.
