2004 ACURA MDX TORQUE CONVERTER ISSUE. I CAN FEEL/HEAR THE VIBRATION/SHUDDER/GRINDING BETWEEN 20-50 MPH WHILE MAINTAINING THE STEADY SPEED WITH LIGHT LOAD. THE SAME ISSUE HAPPENED ONCE WHEN THE VEHICLE WAS AT AROUND 45000 MILES. THE DEALER REPLACED THE TORQUE CONVERTER UNDER WARRANTY. HOWEVER, THE SAME ISSUE CAME BACK AT AROUND 75000 MILES UNTIL NOW AT 93000 MILES. IT WAS ONLY NOTICEABLE AT AROUND 30 MPH, BUT NOW CAN BE NOTICED BETWEEN 20 AND 50 MPH. *TR

FUEL/PROPULSION SYSTEM
EXHAUST ENTERING CABIN WHILE UNDER ACCELERATION OR UNDER LOAD. THE EXHAUST ENTERED CABIN ESPECIALLY WHEN THE HVAC SYSTEM WAS IN "RECIRC" THE DEALER AND ACURA WERE UNABLE TO FIND THE PROBLEM AFTER MULTIPLE VISITS. I DOCUMENTED THAT CARBON MONOXIDE WAS BUILDING UP INSIDE TO ALARMING LEVELS USING A REAL-TIME INDUSTRIAL GAS DETECTOR LEVELS EXCEEDING 160PPM WHILE PULLING A ~3000 LBS BOAT ON THE INTERSTATE WITH A SLIGHT HEAD WIND. (BEING MEASURED FROM FRONT SEAT/ I HAVE VIDEO RECORDINGS OF THIS AND OTHER DOCUMENTATION SHOWING THE BUILDUP AFTER NORMAL ACCELERATION ENTERING INTERSTATE ETC. THE ACTUAL PROBLEM WAS DISCOVERED WHEN I PERSONALLY WAS INSPECTING THE VEHICLE AND FOUND BOTH REAR BODY PLUGS MISSING. THEY ARE AT THE REAR OF THE VEHICLE ONE ON EACH SIDE THAT LEADS TO THE INTERIOR OR THE VEHICLE. ONCE POINTED OUT TO THE DEALER THEY WERE EMBARRASSED AND FIXED IMMEDIATELY. THE PLUGS WERE LOOSE FITTING SO THEY GLUED THEM IN. THE ISSUE NOW SEEMS TO BE RESOLVED. I HAVE NOTICED SEVERAL OTHER INTERNET POSTINGS WITH SIMILAR ISSUES. IT IS A SAFETY ISSUE IN MY MIND BECAUSE OF THE CO IF YOUR DRIVING NORMALLY AGAINST THE WIND AND THE HVAC IS IN "RECIRC" THE LEVELS WILL BUILD UP >35PPM ESPECIALLY IN HIGH WINDS OR HIGHER ALTITUDES AND YOU CAN'T SMELL IT.
