CarComplaints.com Notes: The only area of real concern for 2011 Mazda CX-9 owners is the brake booster.
In 2014, Mazda extended the warranty on the 2007-2013 CX-9 brake booster to 7 years / 90,000 miles. However this extended warranty has expired, so buyer beware.
This Mazda CX-9 brake booster failure isn't terrible in terms of repair cost — it "only" costs $550 average to fix. However it is a safety issue when the brake booster fails as it increases stopping distance. Owners have reported having to stomp on the brake pedal, & crashes/injuries have been reported due to this CX-9 brake booster defect.
I own a 2011 Mazda CX-9 Grand Touring AWD with 70,500 original miles. I service the vehicle within or below the recommended service durations listed in the owners manual. Approximately 3 weeks ago I noticed 3 black spots of oil on my garage floor where the front half of my vehicle parks. After close evaluation I suspected that the oil was coming from the PTU (Power Transfer Unit). I crawled under the vehicle and realized that my suspicion was correct.
I began research on the internet and quickly realized that this is a common problem with 2010 - 2014 CX-9's. The internet also lead me to an extended warranty issued by Mazda back in April of 2014. I never received the extended warranty because I am the seconded owner. I purchased the CX-9 in March of 2015. The warranty coverage was for 7 years or 90,000 miles which ever comes first. My vehicles "in service date" was January 1, 2011 so, I missed the warranty cut-off date by approximately 7 months though I am just shy of 20,000 miles under the warranty duration. I had numerous conversations with Mazda North American and a local Mazda Dealer. They "understood" my frustration yet were only willing to provide me with a $1,000 hardship amount on a $6,500(+) repair or 4% below employee discount on a new Mazda product. I payed cash for this vehicle so, I am not interested in a car payment at this time. The repair option appeared to work the best for me. Even with the repair cost I could sell the vehicle after it is fixed and be ahead of the dealer trade-in-value with it broken.
I also own a 2012 Mazda 3 however, my next vehicle purchase will not be a Mazda. I am done with the brand. The PTU cost is just south of a $1,000 dollars. However, when the PTU went out it took down the transmission spline which requires a completely new transmission. It cost $5,500 to replace. My advice is if you are interested in purchasing this vehicle in the model years mentioned confront the dealer and ask them if the PTU and or transmission have failed and/or been replaced before you purchase. The repair might or should appear on the vehicle history report. Make them aware of your knowledge. I researched this vehicle heavily before I purchased it but, somehow I missed the elephant in the room. I just don't want others to make the same mistake I did. If others have had this issue please provide me with the details.
