Overall, this is a great vehicle. The comfort and features are fantastic, but the handling could be better. My engine sometimes "jumps" during quick acceleration and the vehicle does NOT inspire confidence during sudden/emergency braking. I love the Navi system, but the voice control is horrible -- it never recognizes what we say, so we just use the touch screen. On the positive side, the MDX is very roomy and comfortable, and the Bose sound system rocks.
Comfort, roominess, Bose, XM, heated seats. Build quality is very good.
Voice recognition on the Navi and the emergency handling/braking of the MDX need improvement. Little "luxury" extras like xenon headlights and turn indicators on the side of the vehicle (like other luxury makes) would be nice. Also, sunroof should have one- touch open.
