I have a 2016 Acura MDX with only 120,000 miles on it. Recently I started hearing a knock coming from the engine. I have taken it to three different mechanics, including an Acura dealership mechanic. I was informed by all three to not drive the car due to the fact that it was a rod bearing defect/problem. They all commented that I was lucky that it had not thrown a rod or I could have been injured or possibly had my engine freeze up while driving injuring myself or someone else. After some thorough investigation/research, I have been informed that my make and model has been recalled for the same issue, unfortunately, my Vin number is not included in the recall for whatever reason.
