My brakes started feeling spongy but hard to push when I would try to come to a stop. It felt at times like my car wasn't going to stop. I stopped driving it and the brake booster was replaced. At that time, I lost brakes completely. The brake peddle goes all the way to the floor when pressed. Hopefully the booster is a bad one.

I have a problem with the brake light switch. It works for awhile and then stops working. When I press the brake pedal the brake light may or my not come on and that is while sitting still or while the car is moving. I have replaced the switch several times.

I was taking my daughter to high school in the morning with my son in the car as well. In the parking lot of the high school, I applied the brakes but the brakes did not work. My foot was all the way to the floor when they finally caught but I was out in the line of traffic and luckily no one hit me and injured my son or myself. After replacing the rotors and brake pads that did not fix the situation, I have since learned that the brake booster has been an ongoing issue with mazda cx-9 that was even investigated by the federal safety agency without having a recall. How does something so critical in the safety of lives does not generate a recall that the federal safety agency has seen repeated complaints of the same issue without advising or caring about the safety of the consumers and other drivers. It is an ongoing issue that mazda has not addressed or corrected.

Hissing sound when brake pedal is pressed. Pedal gets really hard to push then it goes to the floor when attempting to stop the vehicle. In a panic stop it feels that the car will not be able to stop. I am told that the brake booster has failed. The mileage on the vehicle is approximately 138,000 miles.

Mazda cx9 break booster diaphragm leakage. I recently purchased a 2009 mazda cx9 that almost got me killed. I was driving down the highway with my family in the car when all of a sudden I had to slow down because the car ahead of me abruptly slowed down. I pressed my breaks to slow down and it felt as hard as a rock prompting me to make sharp maneuver into the other lane, thankfully no other cars were coming on that lane. Upon making home I went on the computer and research the issue. I found out that the problem is due to a manufacturing defects with the break boosters in the cx9 and mazda is aware of the issue. I took the car to a mazda dealership where I was told to pay $680 to have the issue fixed because I missed the 2015 deadline set by mazda to have the break booster fixed. I was so upset, I called mazda USA where I was told that there is nothing they can do about the issue. To rob salt in the wound the lady I spoke to on the phone advised my to make sure that I schedule an appointment with the local mazda dealership for the open recall on the airbags issue. (which I interpreted as "if your breaks fail and you die, the airbag will protect face should in case your family wants to do an open casket at your funeral"). I believe it is unfair for mazda to avoid fixing a known defects in the most important safety system in a car ( the breaks) by passing it off as a warranty program. I am glad to be alive to file this complaint. Please think about peoples safety and not the interest of the manufacturers and do the right thing.

So I was backing up from a parking space on a shopping center and my brake pedal on my mazda cx-9 did not stop immediately. Due to this problem I bump in to some one else's car. The pedal has turn so hard it was difficult for fractions of seconds to know what was going on. After the incident with having an issue with the brake pedal. I notice beside been hard it started making a squeaky noice and also like and air sound under the dash board. I found out there was a class action agains mazda for their brake booster on this model and sure enough, that's what it was, I'm just so blessed it happens in a parking lot and not on the freeway. So I called mazda and they said they will cover the part but I have to pay for the work done to the vehicle. So I did a research on pricing and I found out mazda is charging $269.00 for the wok done, supposedly them covering the part, and outside that is just around the same price else where. Not only that they did not cover everything most likely my insurance may go up and to add to the problem they will charge me for renting a car while they fix it. There is no help with a part that should not have any problems in the time frame of the year of this vehicles. And it was manufacture defect.
