CX-9 6-cyl

  • 73,000 miles


I had to replace both front wheel bearings by 73,000 miles. I would consider this a wheel bearing defect, as I never had to replace this on any of my cars during my 27 years of driving. Mazda Cx-9 is based on Ford edge and Ford is known for bad wheel hub/bearings and this may be related. Shouldn't this be recalled" I'm unhappy with this car as I feel this repair is too soon and not cheap, $650-700 per wheel. If the car was over 100-150K miles, then I would understand one wheel bearing replacement, but two within 73K miles" read some blogs that it's not unusual to replace all four wheel bearings on this car under 100K miles. Please advise, as this isn't safe for moms driving with young children like my wife, let alone others. This car should be investigated, recalled asap and repaired free of charge or refunded. Thank you.

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.

When driving under 20 mph entering into our neighborhood, heard a loud "pop" - then the front left tire suspension 'popped off' the tire, causing the car to lose control and hit the curb with the right tire. It appears that the suspension just "popped off" the joint causing the tire to become 'dislodged' from the vehicle - and sent the car into the curb - see pictures. No police report was taken as it did not involve personal injury nor another vehicle. Upon investigation on the web, it appears that NHTSA has an open investigation into similar problems with 2007/2008 Mazda Cx-9S (see action number: PE15022) - which is why I am writing to you now.

I was making a left turn on a parking lot when I heard a loud crunch coming from the front of the vehicle and fully lost control of the car. When I came outside to see what happened I saw that ball joint on my front left (driver side) broke, the wheel with part of the axel fully out, and that break fluid was spoiled all over. Imagine this happening on the fighter when I was driving with two of my young kids!!

While taking a right hand turn in the parking lot of logan airport, and travelling about 5-10 mph, my car made a loud noise and came to a sudden and abrupt halt. I stepped out of the car and discovered that the driver's side front tire had disconnected from the steering arm. The car was immobilized, and I was not able to move it out of the way of other traffic in the airport parking lot, causing chaos in the parking lot and causing them to temporarily shut down an entire floor of the parking lot while they struggled to tow the car out of the way. The car was subsequently towed to a Mazda dealership and the tire arms and ball joints were repaired pursuant to a recall (8515G). The front tires were also unevenly worn and replaced, very likely from the ball joint / steering arm issue, and cost $481.55. Mazda would not reimburse for the tires because I could not locate receipts to prove I had rotated the tires at the appropriate intervals, specifically stating "our dealer was unable to confirm if the wearing of the tires were due to the recall item as there was no supporting documentation indicating the proper maintenance on the tires". I do not believe most people keep records of every oil change / tire rotation they have done, but the wear was very consistent with what would be expected for ball joint issues. Furthermore the car had been inspected by the state of Massachusetts in the month of September, and no uneven wear was found at that time, giving further indication that the uneven wear was linked to the ball joint / tire rod issue. Fortunately this did not occur one day earlier while towing a boat on the highway with my disabled son, this could have easily been a multi fatality accident. I have literally had nightmares over this possibility. This is an extremely dangerous situation.

Was driving on neighborhood road, heading toward a state highway when all of the sudden a large boom occurred and I lost total control of the car and went up the curb and onto the sidewalk. I thought I'd blown a tire but got out and saw the entire wheel was disconnected - the suspension ruined. Would be happy to share pictures mechanic says ball joint, cv joint came completely off as well as brake fluid all over. I read online about similar issues and that NHTSA has an open investigation under NHTSA action number: PE15022. Consider this another case! I'm thankful there were no people that I swerved into when losing control! this is clearly a safety hazard- ay least in states where salt is used on roads, like here in mn I expect Mazda to take responsibility and pay for these repairs please contact me with additional info or next steps. Thank you! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was pull out of my office parking lot and turned right on to a 1 lane road. As I turned right the lower ball joint dislodged from the control arm. It pull the drivers side transaxle with it and it tie rod ends. Slamming my car to a halt and almost causing an accident with the car behind me. The wheel faced left even though my car was still slighty turning right. This is a danger and a hazard, I've also heard this is serious problem amongst other Cx-9 drivers....

On 06 June 2015 at approximately 1400 my wife was making a left hand turn through an intersection at approximately 15 mph. Near the end of the turn the front passenger wheel broke loose turning nearly 90 degrees to the right and jammed itself into the rear of the fender well. The car was immediately immobilized and came to an abrupt halt in the middle of the intersection. Looking at the damage it was obvious that the lower ball joint had failed and broke completely free. This caused the wheel to turn nearly 90 degrees to the right which subsequently ripped out the cv axle from the transmission. Had this occurred at highway speeds the results could have been deadly. The vehicle had to be towed to a repair facility where the control arm/ball joint assembly, the cv shaft, and sway bar link was replaced. There is also fender well and body damage that will have to be repaired. On 10 July 2015, I noticed an unusual instability while negotiating wide turns on the highway. It felt as if the vehicle had a wheel loose. While turning to the right, the vehicle would abruptly turn even sharper to right almost causing an unintentional lane change. After coming out of the turn I could feel the vehicle suddenly correct itself. Once I arrived at my residence I jacked up the front end of the vehicle to inspect the front wheels. The front passenger wheel seemed normal (was repaired in June 2015 as mentioned above). Much to my dismay when inspecting the front driver side wheel, I discovered that the ball joint on this side is now broke. It is not separated, but is clearly broken as evidenced by the excessive movement and clunking noise when moving the wheel from side to side as it is suspended above the ground from the car being on a jack. I will be having this repaired this week once parts arrive from the local Mazda dealer. Bottom line: I no longer feel safe in this vehicle.

While making a right turn into a parking place, the right front ball joint broke and cv joint became disconnected, causing the wheel to become disconnected from the car and pushing the wheel well back under the passenger door, making it inoperable. The tow driver said I must have hit something really hard, but in the two and a half years I've had this car, I've never hit anything! I drive a lot for my job and am grateful this didn't happen while I was traveling 70 mph on the highway. It was very scary and has shaken my confidence in this car. I had the car repaired on an emergency basis, but the mechanic told me while the other ball joint was safe enough for me to make the trip home (350 miles), I should definitely get it checked out as well, as it looked suspect for the long term. The car is at the mechanic now, and I was a nervous wreck driving it home earlier today.

CX-9 6-cyl

  • 112,080 miles
I had been hearing a knocking noise in my car when I went to make left or right hand turns for approximately a week. After having my mechanic investigate he took a look at the ball joints, they are 'non-serviceable, ' which means they are a sealed unit. He said from what he could tell they were fine. Later that day I attempted to pull out of a parking space. My wheels were spinning in the snow, I got out and took a look and my front left tire was off! the ball joint was no longer attached the car. The only thing securing the wheel to the car was the tie rod. After having it towed to my garage both lower control arms were replaced on the vehicle (one per side) along with the cv joint. They were replaced with Mazda parts. Inspection on the passenger right side revealed there was barely any grease in that ball joint. I had luck on my side that day otherwise I am certain someone would have died.

I was driving slowly and approaching a stop sign. As soon as I stopped I heard a loud noise and my car jerked forward. The front driver side wheel disengaged from the vehicle and was jutting out at an angle. I could not move the car whatsoever. The tow truck driver informed me that my ball joint and axle had broken. This could have caused a very serious accident, especially if we had been driving faster or on the freeway--I'm very lucky my passenger and I were not hurt.
