got an 07, I love it. I have the sport/entertainment with a bunch of accessories and it is very comfortable. My likes of the mdx:
Drives like a car(taking corners in sport modes/shawd)
Audio system sounds really good
Navi system is fantastic
Pretty versatile, have hauled a lot in it and then the 5000 pound towing
nice deep roar from the motor above 4.5K RPM
Smooth steering wheel
Rear entertainment is really good for longer tips
HFL system is much better than previous acura's
the guages, at night they look amazing...
Blue accents thoughout the front cabin, plus white switches, no more green lights.
the dislike:
Not enough power, it does 0-60 in 7.1....
costs almost 80 dollars to fill up, but it does last a long time (400 miles+)
Cleaning it, due to all the crevices, its hard to clean it properly unless you take your time with a q-tip
The few problems with the MDX ( i have only had cubholders and clunk, but both are fixed):
1. The sides of the dash tend to have a large gap, but easily fixable
2. rear cup holders get stuck, Honda has an updated set to solve this
3. The sport suspension MDX owners have a slight clunk in the rear, but this was fixed by honda on 2008 models, solution on the 2007 was to replace a bolt causing the noise, and also grease the bump stops.
4. The tech package owners (normal suspension) have a clicking noise, honda is working on a solution with new bushings to solve this, but the problem occurs on very few MDX's.
5. Oil change, the MDX has some stupid deflector near the oil drain bolt, it sprays oil everywhere if you use it, best thing is to take it off (simple bolt), but if the dealer changes it, no worries
6. Leather wear, the MDX has 100% real leather, and it tends to wrinkle easily, but after it wrinkles, no further damage occurs.
7. Owners have complained of blue jeans staining leather, easily solved by cleaning with leather cleaner once every few months.
Gas mileage isn't the best, in city I get about 17-18 if I drive nicely, Highway, I have gotten 23-24, at speeds of about 70-75.
Have 13.5K on it, runs very well, I have had maybe 1 rattle from it, but that was due to a soda can top pushy thing.
