Some customers may complain of signs of oil on the struts or shock absorbers. In most cases the oil that is present is normal, and a result of the oil that remains on the shaft during the normal sweeping process of the shaft seal. Follow the inspection guidelines below to determine if the condition is a result of the normal sweeping process or a failure of the shaft seal.

What stands out
Suspension accounts for 36% of every owner complaint on file for this vehicle — the dominant problem area across 7 categories tracked.
Owners have filed 31 suspension complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of the 2007 CX-9 report catastrophic suspension failures centered on lower ball joint separation and fracture, occurring across a wide mileage range (69,000 to 141,000 miles). The dominant complaint: a sudden loud pop or snap, followed by loss of steering control and front wheel detachment or misalignment. In the worst cases, the wheel lodges in the fender or the control arm jams into the frame. One owner experienced this failure twice within five months—first on the passenger side at low speed, then on the driver side at 65 mph on a highway with family aboard. Multiple owners report near-misses where the timing prevented collision with other vehicles.
Mazda issued recall 15V451000 to address lower control arm and ball joint corrosion, but owners describe a pattern: the repair fails again within 20,000 miles. Dealers then deny coverage, claiming warranty has expired or the recurrence falls outside the recall scope. One owner had the repair performed three times and reports the same components keep breaking.
Secondary issues include premature front wheel bearing failure (with rear bearings failing shortly after) and abnormal suspension noise. Owners also cite extended delays in obtaining recall parts—in some cases, dealers report unavailability for over 18 months after recall notification, leaving owners unable to address a known defect. Repair costs range from several hundred to over $1,700 depending on cascade damage from wheel detachment.

Failure modes owners describe
Lower Ball Joint Failure/Separation
Lower ball joint fractured, separated, or completely snapped, causing front wheel to detach or become misaligned with the vehicle. In multiple instances, owners report the wheel lodging in the fender, the control arm jamming into the frame, or the wheel turning perpendicular to the vehicle. This is the dominant failure mode across complaints.
When: Mileage ranges from 69,000 to 141,000 miles. Multiple owners report failures recurring after recall repair 15V451000 was performed. One owner had the same failure occur on both driver and passenger sides within a 5-month period.
Symptoms owners cite: Loud pop or snap sound from front suspension; Sudden loss of steering control or inability to control vehicle direction; Vehicle drift or jerking to one side; Front wheel detached, dislodged, or turned perpendicular to vehicle body; Abnormal noise when turning steering wheel or making turns; Steering wheel lock-up or sudden 360-degree rotation; Grinding sound during failure
Repairs/costs cited: Owners cite replacement of lower ball joint, lower control arm, inner/outer tie rods, CV axle, shock/strut assembly. One owner reported repair costs over $1,775; another quoted $587 plus taxes for ball joint and tie rod end repair.
Recalls/TSBs owners mention: NHTSA Campaign 15V451000 (Suspension) issued to address lower control arm and ball joint corrosion. Multiple owners report that parts for the recall repair were unavailable for extended periods, delaying fixes. Mazda issued Service Bulletin 2/1/2008 for rear wheel bearing ABS sensor shape issue. Owners report that dealers denied warranty coverage after original warranty expired or claimed failures were not covered under the recall after initial repair.
Front Wheel Bearing Failure
Front wheel bearings degraded, with rear wheel bearings failing shortly after front bearing replacement. One owner reports that Mazda issued a service bulletin regarding improper ABS sensor shape causing bearing noise, but the bulletin only covers repairs within warranty period.
When: At 58,000 miles owner reported humming noise and front bearing replacement under warranty. Rear bearing failure occurred one year later at approximately 74,000 miles, outside warranty.
Symptoms owners cite: Humming noise from front wheels; Frozen bearing (potential for severe danger when bearing seizes)
Repairs/costs cited: Front wheel bearings replaced under warranty. Rear bearing replacement needed but owner charged out-of-warranty cost.
Recalls/TSBs owners mention: Mazda Service Bulletin issued 2/1/2008 addressing rear bearing noise from improper ABS sensor shape. Coverage limited to vehicles still under warranty. Mazda refused to cover rear bearing replacement at 74,000 miles, citing expired warranty.
Abnormal Suspension Noise/Steering Issues with Loose Components
Owners report abnormal humming, grinding, popping, or creaking noises from suspension, often accompanied by loose or worn ball joints and tie rod ends. In some cases, inspections revealed components with play or looseness that required replacement.
When: Varies; one owner reports noise starting around 50 mph during low-speed driving. Another reports noise in winter conditions. Another at 132,000 miles. One owner had noise and loose components detected 20,000 miles after recall repair 15V451000.
Symptoms owners cite: Humming or grinding noise from suspension; Abnormal noise when turning steering wheel; Creaking or popping sounds; Vehicle shaking around 50 mph; Loose ball joints or tie rod ends detected during inspection
Repairs/costs cited: Ball joint, tie rod end, and control arm replacement. One estimate $587 plus taxes. Components found to have play in them despite prior recall repair.
Recalls/TSBs owners mention: Recall 15V451000 performed but components became loose again within 20,000 miles of repair. Mazda stated the recurrence was not normal and repairs should last over 10 years.
Recall Parts Unavailability
Multiple owners report that replacement parts for recall 15V451000 (Suspension) and related recalls (16V356000, 17V457000 for airbags) were not available for extended periods after recall notification, preventing timely repairs.
When: Complaints filed regarding parts unavailability spanning several years. One owner notes repeated calls to dealer over 1.5 years with no parts availability.
Symptoms owners cite: Notification of recall received but parts unavailable at dealer; Dealer unable to schedule recall repair appointment; No authorized dealers nearby to perform recall
Repairs/costs cited: No repair completed due to parts unavailability. Owners unable to address known defect.
Recalls/TSBs owners mention: NHTSA Campaigns 15V451000, 16V356000, 17V457000 issued. Multiple complaints document that manufacturer/dealer exceeded reasonable timeframe for parts availability. VIN tool confirms parts not available.

Dealer wants to charge me the diagnostic fee of $170.00 before performing this recall, plus they said they are not taking any recalls
The vehicle started to have problems with the car shaking around 50mph. So we planned to have it looked at since we heard that this particular model has some known issues that may become severe. During the drive to the car shop (literally 1 mile from home) the axle/bearing or front suspension separated from the car!!! The front left wheel and joints separated from the car; the wheel looks like it…
