 The CX-9 at first seemed to be a great car, very roomy and fairly comfortable. Fuel economy seems to be low for the size of car, averaging only 14-16 in-town, and 18 on the highway. The biggest challenge, and reason for the bad review is the Transfer Case.  I have found several other reviews, matching this issue, and as far back as 2011. The transfer case failed at 12,500 miles, and filled the car with toxic oil fumes from the gear oil aspirating through the venting system. My wife and daughter got sick, and had respiratory issues through the evening and night. The technician informed me this was a known issue with the CX-9, and they have new T-Cases on hand due to how many they replace. The tech also informed me that this happens frequently at even a lower mile range, sometimes as early as 3,000 miles.  Customer service was completely accepting of responsibility, and attempted to down play the "known" part of the issue. Even though it is easily found on several review sites, and the dealer had recent examples to discuss with me while I was turning it in for repair.The toxic fumes filled the car within a few seconds, and fully engulfed the interior with a stench that has not come out, similar to cigarette smoke.On a smaller, and a much less horrifying note, the Blue Tooth in this car takes up to five minutes to connect. Very poor blue tooth system.
