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.
