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.

Takata recall I had to put in my VIN to make an appointment for recalls & was sent a message back stating there are no recalls on my car. When I looked it up on your website it says my car is in recall for airbags and lower control arm. But according to the Mazda dealer & the Mazda website I don't have any recalls on my car!!! so to date I haven't been able to fix the items that are being recalled. When the recall for the airbags came out I contacted Mazda & there was no recall. Again when the recall was expanded I contacted Mazda. My vehicle was not on the list. I went to your site to see what you had about my car & discovered you have 2 open recalls on my car that as far as far as Mazda is concerned I have none. Yet you have on your website that I do so I am trying to get to the bottom of this. Does my car have any recalls or not" I also want to point out that there was a recall on the transfer case on my car. Now when I bought the car the reason why I bought it with high mileage was because the car was supposed to be certified preowned. I was given the 1 year warranty. Then I was told that the recall on the transfer case would be valid until 100000 mile. So when my transfer case needed to be repaired at 92000 miles. I contacted Mazda & after months of back & forth I was told I didn't qualify for them to take care of the repair even though it looks like a monster took a bite out of the transfer case at 92000 miles because according to their records my car was not certified preowned. Iasked to reconsider becsuse the transfer case wss completely destroyed St 92000. They said they could not make an exception with me becsuse then they'd have to make exceptions for others. I was told to get in touch with the dealer I'm getting in touch about that this week. There is something odd about all of this. How come Mazda doesn't have the recalls for my car that you have"

My vehicle has two unresolved recalls. The first dates back to July 2015 related to the front suspension ball joint fitting. This has been brought to the attention of South bay Mazda on multiple occasions and the issue has not been resolved nor have I ever received a response from them. A second recall was issued for Mazda Cx-9S related to the passenger side airbag in May 2016. Due to the poor customer service at South bay Mazda I've taken my business to culver city Mazda. Culver city Mazda gave me a rental vehicle on Aug 8th 2016 while Mazda na orders and delivers parts. I've had the rental vehicle for nearly three months with no resolution in sight. It's very stressful to drive a rental vehicle which I will be liable for if anything happens to it while in my possession. It's also very disturbing that these recalls are taking so long to remedy. I'm extremely disappointed with Mazda at this point. We're growing more concerned with what the outcome of these recalls will be and for the safety of our family in our car when it's returned.
