how many miles can I expect from my 2011 MDX car?

Hello, there is no such thing as expected miles. If you perform needed maintenance regularly and drive normally, this vehicle, I would guess, should be in decent shape above 200,000 - 250,000 miles. Not a scientific answer or one that has references - just a conservative estimate based on what I've seen in the "real world". Be sure to perform your maintenance services in a timely manner, using Acura parts especially for best results.
