general problems of the 2013 Mazda CX9

Brakes failed while driving. Mazda dealer did not fix this known defect under recall ssp93.

The brake became very stiff and made a hissing sound when applied while driving. I brought my car to an independent mechanic and back to the dealer where I brought the car and they both confirmed that I needed to replace the brake booster. That the hissing sound was leakage.

Brake booster hissing when applying breaks while traveling and stopped.

Brakes pedal on my wife's car became hard when pressed on (regardless of speed) and noticed a hissing noise when applying brakes. The worst and scariest part is that the brakes didn't stop the car and felt as if I was applying the brakes on a car that was not turned on. Luckily we didn't get into any accident and stop driving the car. Had car towed to mechanic who informed me that the brake booster was bad and needed to be replaced. Checking online and this appears to have been an known issue with earlier Cx9 cars.

A faulty brake booster.

My brake pedal became very hard to press down to stop my vehicle. A hissing sound was coming from the pedal. Even at low speeds 20-30 miles per hour I was not sure if my car would stop. I was pressing down on brake pedal has hard as I could. Took it in for repair 5/22 I was told it was the brake booster assembly this was known to be faulty in this model Mazda but to recall was incorporated. Repair cost was $760. 00 put of my pocket.

My 2013 Mazda cx-9 has 48,841 miles on it. Brakes recently started making a hissing noise then became hard to depress. I had a difficult time stopping the vehicle to avoid a collision on several occasions. Also, I was sitting at an intersection with construction and had to sit through several red lights, brakes were making the hissing noise and the vehicle's rpms started fluctuating and my car died. When I put the car in park, the rpms stopped fluctuating but as soon as I put it in drive with the brakes depressed, the rpms started fluctuating again. I researched the issue and found numerous online complaints regarding this issue mainly with 2012 Mazda cx-9 brake power boost unit failure. I contacted the Mazda dealer to schedule service and they advised there is no known warranty extension or recall for this issue for my VIN.

Tl the contact owns a 2013 Mazda cx-9. While driving 45 mph, the contact heard a hissing sound when the brake pedal was depressed. The vehicle was taken to browning Mazda (18827 studebaker rd, cerritos, CA 90703, (562) 924-1414) where it was diagnosed that the vacuum seals failed on the brake power booster, and the brake power booster needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was notified and the contact was informed that the issue was due to wear and tear. The manufacturer provided case number: 1-1231715620. The approximate failure mileage was 51,000.

A truck swerved into my lane and I tried to brake. The pedal didn't immediately depress so I had to serve. Jumped a curb and hit a sign. More than $11,000 of damage. The brake is very difficult to depress quickly.

Loss of braking power and hissing noise heard in the engine compartment. The first time you brake it felt okay but any subsequent braking it felt like there were no power brakes. Brake pedal had to be pushed really hard to get it to even stop. When stopped at a light facing down hill, brakes started to slowly loose grip and caused the car to roll forward. It felt like brake fluid was slowly being drained. I had to consider putting the car in park while stopped at a light so as to not run into the car in front of me. We took it to the dealer and they found that the brake booster was completely faulty and they replaced it. Brake problems have existed on other Mazda cx-9 vehicles: 2008, 2010 & 2011. Nhtsa already investigated the 2010-2011 cx-9's and Mazda "extended the warranty" on those vehicles. What about the 2013 cx-9's? why was the problem not yet remedied on the 2013? what good is a vehicle if you cannot stop? safety should be first priority and Mazda has failed miserably with the brakes. The brake booster was supposedly "fixed" under warranty, the next day the orange wrench mechanic light illuminated on the dashboard and cruise control broke failed to engage. It turns out the brake booster and braking switch was still faulty even after the dealer fixed it. The vehicle thought the brakes were continously being pushed so the cruise control would not engage, even though no brakes were being pushed and we were driving 55 mph down the interstate. We took it back and they have supposedly "fixed it this time". This is the 3rd major repair (also faulty and replaced or will torque converter, transmission, lower control arms and ball joints) of this vehicle and it is now less than 3 years old! I do not think I would buy another Mazda again.

Lost control of vehicle coming down a ramp in a parking garage, causing me to strike pole in garage, or would have careened over 6th FL railing down 6 stories to street. Vehicle in motion.

Tl- the contact owns a 2013 Mazda cx-9. The contact stated while driving 40 mph, suddenly she heard her vehicles brakes would hiss when in use. The contact had not had her vehicle diagnosed for formal diagnostic testing. However did notify the manufacturer of the potential defect. The vehicle was not repaired. The failure mileage was 32,885. Az.

While driving my 2013 Cx9 I noticed the brakes required extreme force to engage and I heard a hissing sound when I engaged my brakes. Since I had had the same issue with the brakes on my 2010 model, I immediately contacted the dealership where they are currently repairing the brakes under warranty.
