general problems of the 2008 Mazda CX9

While driving the vehicle the brakes became hard to depress and a hissing came from my steering column, the car would not stop or respond to stop. I had to downshift to neutral to get the speed slow enough to stop - and had passed through an intersection while in failure. I had also had symptoms I did not know at the time may be related which was at a stop at dunkins or a drive through at a stopped position - where the car would run rough the last few weeks. I thought the rough idle was gas related. I can no longer drive the vehicle and am told this is brake booster/pump issue / that other of the same parts in fords and other manufacturers are now extending customer sat programs like 13n02 because of faulty parts in the brake booster. The vehicle can be towed or seen for this problem. The vehicle has no existing coverage of the faulty brake booster. This is a car insured for my son (21) to drive and it is a saftey risk that this went while driving, I'm happy it was myself driving that day. Problem has been confirmed as a brake booster pump/booster failure by a service professional. No warning lights - just not able to stop the car when stepping on the brake. Thanks.

The contact owns a 2008 Mazda cx-9. The contact stated while driving approximately 30 mph, he noticed that the brakes felt loose and the braking distance had become extended while attempting to stop the vehicle. The contact stated that he heard a hissing sound while depressing the brake pedal. The contact stated no warning light was illuminated. The contact stated that the brakes failed completely while attempting to stop for a traffic signal and the vehicle rolled into the intersection. The contact had taken the vehicle to a local dealer, where it was diagnosed that the brake booster was malfunctioning and needed to be replaced. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 115,000.

My control arms bearings and joints are rusted and the dealership says they aren't covered they were fixed 5 years ago and they are definitely separated and hazardous.

Sometimes the blind signal works sometimes it doesn't sometimes it blinks on the screen and when switching lanes, brakes keeps going out ball joint keeps popping hard shift or knock in reverse and when placed in park had repair done several times. Dvd wires keeps going out/shortage m. Sometimes seat belt blinker work and sometimes it doesn�t.

I was driving and all of a sudden I lost the pressure on my brake and my car wont stop. I had to depressed the brake so hard. Then I started hearing a hissing noise while stepping on the brake.

Hard to push the brake pedals and always hear a hissing noise whenever stepping the brakes. It is a commonly known-problem with brake booster diaphragms, and Mazda agreed for "special service program" that extends the warranty coverage for repairing this condition to unlimited time and mileage, but I never received any notice. No incident yet, but almost crashed on freeway and at especially downhill stops several times. Need to be replaced by Mazda ASAP!.

Vehicle suddenly did not brake as expected. Brake pedal was hard to press and unresponsive. Brakes made noise while depressed. Vehicle was being driven at the time, and did not have the issue earlier in the day.

Brake hissing from pedal area and brakes are very hard to press. Difficult to stop vehicle without applying lots of pedal force until a certain point where booster starts working and vehicle stops quickly. Dangerous at first because vehicle doesn't seem to stop without a great deal of pedal force then suddenly stops quickly after more pedal travel. Also, engine runs rough when hissing sound is heard- probably due to loss of vacuum. Problem is at all speeds. It takes a great deal of distance to stop at higher speeds for emergency braking (very dangerous).

I had to replace my tires because of the ball joints and causing my wheel to come off. My breaks sounds horrible even after I had them serviced if it rains really bad I get this cranking noise I have a weird sound to my vehicle right now coming from the front of the vehicle again and not sure what's the problem. I'm afraid to drive the vehicle to fast because I have children what's going on with this vehicle.

The contact owns a 2008 Mazda cx-9. While driving approximately 35 mph, the vehicle decelerated independently and the abs and tcs warning lights illuminated. As a result, the tires failed to function correctly. The vehicle was towed to an independent mechanic where it was diagnosed that the brake booster needed to be replaced. The vehicle was repaired; however, minutes later, the failure persisted. The vehicle was towed to a dealer where it was diagnosed that the pedal switch needed to be replaced. The vehicle was repaired, but the failure persisted. The manufacturer was notified of the failure. The failure mileage was unknown.

While driving and coming to a stop, the brake pedal went real hard and car would not stop appropriately. This happened multiple times, checked the brake fluid is full as well as changed brakes themselves. . Problem still there and progressively worse, un drivable because of compromised braking. There is only 75k miles on this automobile. Having the car towed to local dealer, where I was told that Mazda has extended the warranty for braking system, which would take care of this problem as well as reimbursement for towing and expenses. This defect is very dangerouse, there was no warning, no warning light illuminated on the dash, I am very fortunate that this was caught before an accident occurred.

The brakes are hard to depress and the car is difficult to stop. If I start the car and depress on the brakes at a standstill, the pedal fells hard and goes down really far will I hear a "whistling" sound and also a "hissing" like if air is escaping.

The contact owns a 2008 Mazda cx-9. The contact stated that the brake pedal was difficult to depress. The contact had to shift the vehicle into park upon coming to a stop due to the failure. The contact also had to allow enough distance between other vehicles due to the brake pedal not completely stopping the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 140,000.

I noticed that my brakes made a hissing sound at random times. Brakes would not work as usual. After "stomping" on brake, car continued to move for several feet.

Lately, my cx-9 does not come to a complete stop within the expected distance (stop sign or signal), for the usual brake pedal travel. I had to lift my foot and brake hard to bring it to stop. Otherisie, cx-9 remains a pleasant vehicle to drive and ride.

There have been a multitude of problems on the vehicle (two sets of brakes, tierod, electrical overhaul vacuum hoses. . . ) the major issue has been oil leaking. This past summer (2011) there was an oil leak. The dealer had the car for several days before diagnosing that it was the rear main seal. The seal was replaced (car was at dealer for nearly two weeks. ) this fall (2011) oil was still leaking. After several days the dealer contacted Mazda corporate and they suggested replacing the transmission, claiming it was not uncommon. The dealer replaced the transmission. Winter/spring 2012 oil still leaking, car is currently at the dealer - claiming it is the rear main seal. Again? wouldn't that have been replaced with the new transmission?.
