There are 3 owner-reported body & structure complaints for the 2010 Acura MDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
This is in reference to Acura Service Bulletin 14-032, Rear Side Body Plug is missing. Both my right and left side body plugs were missing, causing myself and family to experience symptoms of carbon monoxide poisoning for at least a year. I had the exhaust system checked by Acura and and independent garage and they found no issues. I would not have know about the cause if I had not found it in a chat thread in an Acura online community. All owners need to be notified. THIS SHOULD BE A MANDATORY SAFETY RECALL for Acura MDX for 2010-2013.
The contact owns a 2010 Acura MDX. The contact stated that while attempting to open the door, the contact’s grandson exited the vehicle, and the door closed independently. The contact stated that his daughter had experienced the door closing independently onto her right hand while exiting the vehicle. No warning light was illuminated. A dealer was contacted. The vehicle was diagnosed over the phone by the dealer, and the contact was informed that the door check strap needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was referred by the manufacturer to the NHTSA Hotline to report the failure. The approximate failure mileage was 184,000.
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.
