We have owned the MDX Tech for 4.5 months and 5,300 miles.
Overall, we are really happy with the vehicle.
It is good looking, fun to drive and perfect for our family of 4 to go camping and on vacations.
The gas mileage has been slightly over 18 combined which is fine by me.
The only suggestions for improvement would be the transmission and stereo.
Granted, we were "spoiled" with an Audi but... the MDX is smooth shifting but sometimes you have to coax it to the proper gear especially when it is loaded up.
The ELS surround sound is just adequate but NOTHING like the Bose in an Audi.
All that said, I know the Acura will be MUCH more reliable than the Audi.
I also own a 2006 TL.
Looks, fun to drive, powerful engine, decent mileage.
Transmission sometimes needs to be coaxed to the appropriate gear.
It does shift smoothly though.
The stereo has almost no mid range and is just adequate....wish there was an upgrade option.
