Thank you so much. The car is at the perfect price point. I have been looking at buying the 3.6 subaru outback... RDX and leasing an audi allroad wagaon. My mdx was recently totalled. Great car, but really bad mpg. I bet the rdx vibration is due to the VCM. I tried two cars and both had the vibration. What is your service center telling you? Thanks, Matt
