There are two potential issues that I can see in your case.. One is the road feedback and the other the damping system.
That you can feel all the road details does not necessarily mean that it is the suspension.
When I first bought my 2011 MDX, I could really feel all the road details and with time it has gotten very smooth, and it seems it will be getting even smoother with time. I originally thought that my MDX's bushings were really tight, or that the bushing materials were very hard.
My ride, though, is in the soft side.. One way to find out if it is the advanced damping system is to feel for any wobbling.. Does your car wobbles when you ride in an uneven road or when you go over a speed bump one side at the time? When you go through a curve, is the MDX like on rails..? or does it lean somewhat to one side?
If your suspension is too stiff, your vehicle will not wobble/lean at all and when you go through a speed bump, you will have to slow down a lot or it will be really hard on you and the vehicle.. BMW's and Mercedes with sport suspension feel like you are riding on rocks when you drive slow over uneven/bumpy roads... Is that what you feel..?
Just had our 08 Sport at the Dealer for a Clunking Noise in Suspension. Car has 44,400 Miles. After 4 days of trying to figure out what was wrong and speaking to Acura Factory Reps, they replaced Both Front Lower Arm Compliance Bushings and a Right Front Stroke Sensor. They also replaced Both Front Compliance Brackets and did a Wheel Alignment. All under warranty. Now, the MDX is riding REALLY Hard in Sport Mode and Fairly hard in Comfort Mode. In Sport Mode, you feel every little thing on the road, It is much rougher than our X5 Sport Suspension with 20 Inch Wheels. Its also a little jerky from side to side.The Tech noted on the Invoice that the ride felt "Stiff" but it was due to the Active Damper Suspension. They also lowered the Cold Tire Pressure to 30lbs which I put back to 32lbs. I always Drive the MDX in Sport Mode, but now its really too much unless we are in the Canyons. I was wondering if the dealer was able to Overtighten something. Any thoughts would be great !!
