2007 Acura MDX 4dr SUV AWD w/Technology, Entertainment Package (3.7L 6cyl 5A)
This vehicle vibrates badly at speeds above 60 MPH and has noise issues with rear windows down. Although the performance is great, it corners well, and acts like a big 4X4, it's no fun when the vibration pushes you off the highway. The dealer has not been able to fix the problem and Acura said they have company cars the act the same way. "Live with it!"
The car is a fast all weather vehicle.
Find out what is causing this unsafe vibration and fix it. It's not the tires, or the wheels, so quit pointing the finger. It's in the design of the vehicle!
