I purchased this vehicle one year ago and have had some problems with the exhaust system and acceleration. My MDX makes an annoying noise at the 2 rpm mark, and does not have very good acceleration at times; I have had it checked (with little success) at my Acura dealer. There are also some interior noises in the back doors, which is bothersome to listen to at times. I really expected a lot more from this vehicle, especially for the price that I paid. The gas mileage is not that great as well....getting around 14-15 mpg in the city and 17-18 mpg on the highway, and I drive fairly conservative.
The vehicle is very roomy inside and the seats are very comfortable. The Bose sound system is good.
Offer hybrid version like the Lexus competitor in order to improve gas mileage....I pay around $225 a month on gas and I live 7 miles from work!
