Acura MDX (2009) vibration issues: Since purchasing the vehicle new, there is a vibration driving at speeds exceeding 70 mph. The vibration can be felt through the chasis and steering wheel. The dealer has replaced the tires, rims, drive shaft and performed multiple balancing and alignments. The manufacturer representative could not resolve the issue initially, but later suggested the replacement of the drive shaft. This worked initially but the problem has resurfaced again. I filed a lemon law claim that Acura has neglected to respond to fully. They tried to fix it, but the problem is still present and getting worse. When driving the car, it feels at times, as if the wheels are going to fall off. It is often worse when driving up hill when the car is cold and the weather cold. It appears to get better as the car warms up, though. This also appears to be a well documented concern that is documented on discussion boards such as: Edmonds- townhall-talk.edmunds.com/webx/.F13bae6?displayrecent where there are currently 59 posts on the topic and all similar to my experience.
