Who out there has had a problem with the Mass Air Filter Sensor? I have a RDX, 1 year old, under warranty, that just quit on me in the middle of traffic, no overheating, no Check Engine light, no rough run, etc. Called Acura Roadside Assistance, that was a joke, never talked to a person (just a computer) and it disconnected me after repeatedly asking "can we use your phone GPS to find your location), this while I am screaming YES. Towed to Dealer who replaced the Mass AFS and then said it was my fault for installing a K&N Filter which K&N, by the way, is now being tested by KN Filters in California. I installed the KN because I could not locate an Acura OEM, and as the original Acura air filter was so dirty I felt it would not allow any air flow, and in fact way to dirty for the mileage. I have had 2 previous Acura's, both great cars, but it seems to me the new Models are "not what they were".
