2011 Acura Mdx

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. I CONTACTED ACURA CUSTOMER SERVICE DIRECTLY AND I SPOKE TO A CUSTOMER SERVICE REPRESENTATIVE AT ACURA THAT TOLD ME THEY ARE AWARE OF THE PROBLEM BUT THERE IS STILL NO FIX FROM THEIR ENGINEERS. I AM REPORTING THIS ISSUE TO HOPEFULLY GAIN SOME TRACTION FOR THE ACURA ENGINEERS TO FOCUS THEIR EFFORTS ON CREATING A SOLUTION TO THE PROBLEM. I HAVE HAD GREAT SUCCESS WITH THE ACURA BRANDIN THE PAST. HOWEVER I AM DISAPPOINTED THAT I AM BEING TOLD THAT I HAVE TO DEAL WITH A PREMIUM SUV THAT SOUNDS LIKE A DIESEL TRUCK. *TR
