2011 Mazda CX-9 Problems

Brake booster failure. The power assisted braking has stopped working. There are no leaking vacuum hoses and the check valve is working. The brake pedal travels to the floorboard.

The contact owns a 2011 Mazda CX-9. The contact stated while driving 20 MPH, there was an abnormal sound coming from the brakes. The contact stated that the brake pedal was firm and difficult to depress while attempting to stop the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and a case was filed. The failure mileage was 67,000.

The front driver-side lower ball joint suffered a catastrophic structural failure and sheared completely apart while moving. This vehicle was previously serviced under Safety Recall Campaign 15V451000 / Mazda Recall 8515G for this exact defect. The recall remedy part failed a second time, collapsing the front wheel assembly, ripping the CV axle completely out of the transmission casing, causing a hazardous transmission fluid spill, and leaving the vehicle stranded and immobilized in the middle of a live roadway in the dark

I had an issue with the AWD not engaging and the 4x4 light illuminating when driving on snow and ice. No indicators when driving under normal conditions. I had no traction and had difficulty maintaining control of the vehicle while driving at speeds less than 25 mph. I had difficulty gettting momentum from a stop as the tires were spinning and engaging tracion. I took the car into a Mazda dealership for a full circle inspection and found that the 4x4 light was illuminating due to worn-out splines connecting the transfer case. The technician was able to spin the driveshaft, indicating the splines are damaged and need to be replaced. Recommendations were to replace the transmission and transfer case with a repair estimate of $5469.61. Additionally, the technician observed some seeping of oil coming from the tiing cover and reccommends re-sealing it as well as replacing the water pump ( another known failure issue in which Mazda is aware of). Cost estimate of $4319.78. The technician also observed a crack in the right rear differential mount with a repair cost of $442.10. In short, Mazda knew about all these problems. They issued a warrenty extention from my research back in 2014 but never issued any recalls. In short, I didn't own this vehicle in 2014, I purchased in 2016. I was never aware of any warrenty extentions to include these issues and if I was aware, I would have had the services done for repairs. My safety as well as my family's and others are at risk if I lose control of the vehicle due to the AWD not engaging when needed.

The contact owns a 2011 Mazda CX-9. The contact stated that while attempting to park the vehicle at a slow speed in the driveway, the vehicle suddenly experienced unintended acceleration, lurched forward, and crashed into a tree before coming to a stop. The contact was unable to stop the vehicle during the sudden unintended acceleration. During the failure the vehicle sustained front end damages, but no air bags had deployed. No injuries were reported. The cause of the failure was not yet determined. The contact stated that twice in the day before the unintended acceleration, the vehicle jerked forward in traffic however, the contact attributed the issue to the brake pedal not being firmly depressed or the clutch not properly engaged while shifting gear. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 173,000.

While driving the side airbags exploded and I had to stop in the middle of the street, get vehicle towed to mazda dealer in Alpharetta, GA Now, im without a vehicle. What do I do now?

Driving kids to school a few months ago. Car started to smell like burning rubber. I thought it was the garbage truck ahead of us. As we turned the corner 2 blocks later, the car dead stopped and we all went flying forward. It jerked so hard, we are lucky our necks didn't snap. I put the car in park and turned it off. I waited a few minutes as I was too worked up, and started the car again. We got about 50ft before a very loud noise began, almost as if something was dragging underneath. I stopped, and had it towed home. I then had it towed to mechanic. They said bad TRANSFER CASE & DRIVE SHAFT. - TRANS PAN GASKET. I am a single mom with no money to afford to have it fixed in fear of it going bad again. They quoted me 3,500 here in PA.

Defective water pump located inside the engine that when failure occurs can cause coolant to leak into engine causing complete engine failure. This is a major safety hazard due to the fact that these cars with defective water pumps can break down with very little warning in the middle of a freeway! I have contacted Mazda who refuses to do anything due to it being outside warranty but will not acknowledge the safety concern sudden engine failure can cause on a perfectly maintained car. In California there is currently a lawsuit against Mazda for this issue and hundreds of other Ford and Mazda owners who have been caught in very dangerous situations due to this water pump failure issue. The situation we were involved in could have gone very differently and that was my family in the vehicle that Mazda seems to care about a couple thousand dollars more then the value of life... is just ridiculous! Please do the research yourself so no one has to loose their life over this.

OUR VEHICLE HAS WATER DRAINS OR "WEEP" LINES FOR THE SUNROOF. WE RECENTLY HAD THE ELECTRICAL SYSTEM STOP/START, DASH LIGHTS REMAIN ON CONSTANTLY AFTER SITTING IN THE DRIVEWAY DURING THE RAIN. WE LEARNED THAT IF THE DRAINS BECOME BLOCKED THAT WATER LEAKS INTO THE CABIN DIRECTLY ONTO THE BODY CONTROL MODULE (BCM). BECAUSE THE BCM IS NOT IN A SEALED OR WATER-PROOF CASE, YET IS SOAKED IN THESE CONDITIONS, THE VEHICLE IS SUBJECT TO ELECTRICAL FAILURE AS A RESULT. REPLACING THE BCM COSTS ABOUT $1,000. WHEN WE STARTED THE CAR THE DASH LIGHTS THAT WARN OF AN ISSUE WITH MANY OF THE VEHICLES SAFETY SYSTEMS REMAINED ON. OTHERS WENT OFF AND SOFT OF FLASHED. WE COULD NOT DETERMINE IF THERE WAS REALLY AN ISSUE WITH ALL OF THE COMPONENTS FLASHING ON THE DASH SO WE DID NOT WANT TO DRIVE IT FOR FEAR OF AN ACCIDENT. OUR VEHICLE WAS STATIONARY (THANK GOD). WE WAITED FOR A WHILE AND WERE ABLE TO LEAVE FOR HOME, BUT THIS CONDITION IS CLEARLY A HUGE SAFETY RISK.

The front door windows no longer work. Most recently, the drivers side back door will NOT open. The lock is completely jammed - will not open or shut, which is a safety hazard for my child. The plastic parts in this car are failing and putting my family at risk.

WATER PUMP LEAKING IN ENGINE MIXING WITH OIL

AS I WAS DRIVING MY CAR ON A CITY STREET, I LOST ALL STEERING AND BRAKING ABILITY. THE FIRST TIME IT HAPPENED - MAZADA THOUGHT IT WAS A SUCTION FROM THE BRAKE AND A TUBE THAT WAS BROKEN.

I TOOK MY CAR TO HALL IN BROOKFIELD WI TO FIX A RECALL ISSUE. THE DEALER TOLD ME THEY FIXED THE RECALL ISSUE BUT NOTICED ANOTHER PROBLEM THAT REQUIRES THE REPLACEMENT OF THE DIFFERENTIAL BUSHINGS BECAUSE THEY WERE TORN. THEY CHARGED ME OVER $500 FOR THIS ISSUE AND I BELIEVE THE ISSUE WAS EXASPERATED BY THE RECALL ISSUE AND I AM NOT SURE WHY I HAD TO PAY. I HONESTLY BELIEVE IT WAS A WAY FOR THE DEALER TO CHARGE ME FOR THE RECALL WORK BECAUSE IT WAS SUPPOSED TO BE FREE. I AM ATTACHING RECEIPTS FOR THE WORK HALL DID TO THIS COMPLAINT. NOW MY CAR IS HAVING ISSUES WITH PROPERLY ACCELERATING AND IS VERY LOUD.

I HAVE READ IN SEVERAL SITES THAT THIS IS COMMON AND MAZDA KNOW ABOUT IT AND HAS DONE NOTHING TO FIX IT. I HAVE BEEN PULLED OVER SEVERAL TIMES CAUSE OF THIS.
