I now have almost 1000 miles on my 07 MDX and have not experienced any pulling, etc. I usually drive using one hand lightly on the steering wheel and although I do find 07 MDX steering to be heavier as compared to my Camry (which I would say is very light), I am still able to navigate without any problems. I would have liked the steering to be a bit lighter on lower speeds though, but is is perfect for freeway speeds.

similar situation here: No pulling, about 4000 miles, wishing for a bit more boost in the parking lots... and still enjoying my MDX!

Thanks, everyone, that is good to know. I notice that the material on the MDX describes the steering as being variable torque (or something like that). Does anyone know if that means it's potentially adjustable, eg, could the dealer adjust for more boost?

I test drove a 2007 MDX with the 19" wheels and it rode quite rough and pulled to the right. I purchased an MDX with the standard wheels and it rides smoothly and no pull in either direction. Gas mileage registered 20.4 on the 100 mile trip from dealer to home. It has now settled to about 18MPG here in the Orlando, FL area. Am very pleased with the car.

Speed sensitive power steering adjusts boost depending on speed. I don't think your dealer can adjust the boost.

With the MDX, the steering is actually torque-sensing rather than speed-sensing. Torque-sensing works off of the engine rpm, rather than the vehicle speed.
 
End result is more or less the same. And I agree that a dealer isn't likely to mess with it.

I thought torque-sensing was more of a function of the DBW system, as opposed to power steering system itself.

Not quite sure what you meant when you wrote, "a function of the DBW system". Are you suggesting the term torque-sensing steering refers to manipulating the throttle rather than the steering? That would be incorrect.
 
In don't have a link handy, so read up on the 2nd gen TL and TL-S. The base model used a speed-sensing design, while the Type S got torque-sensing. With a little digging, you may find a better explanation of the difference between the two designs.

I agree with you about the tires. I have the base model MDX with the Goodyear tires on it. The steering at highway speed is horrible and a ton of work not to mention a rough ride all the time. I just had a dealer loaner for 2 days that was loaded with the Michelin tires on it. What a difference! Great steering and a much smoother ride. I can't beleive that Acura put the Goodyear tires on their cars to save $25 per tire. AMAZING TO SAY THE LEAST!

I tried finding out information on torque-sensing part of variable assist steering but most of the returns were related to patents. TL (including base) apparently has torque-sensing variable assist steering as does MDX. But no details on how it helps. RL uses speed sensing variable assist system.
 
Regardless, it is highly unlikely that people looking to reduce assist at lower speeds will get any help at dealerships. It’s a part of the design (greater assist at lower speeds, and reduced assist at high speeds).
