“We are currently leasing a 2011 Acura MDX and are experiencing a pinging or engine knock at lower RPM. I had a service technician test drive the car and he recognized the noise and stated that Acura is aware of the problem but does not have a fix for the problem. When I asked if there was potential damage happening to the engine, I was told not to be concerned. Weeks and months later the noise is still apparent sounds like a diesel truck and I am beginning to feel a lack of power. …”
