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
Of the 10 model years of Mazda CX-9 we track for suspension problems, this one carries the most owner complaints on file — 44.
Owners have filed 44 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
The 2008 CX-9 suspension issue centers on lower ball joint separation. Owners describe a sudden loud noise or pop—often while turning at low speed or in parking lots—followed by the vehicle jerking to a stop, with the front wheel turned sideways or completely detached. Several owners were on the highway moments before the failure occurred, narrowly missing what they describe as a likely rollover or fatal accident.
The failure happens across a wide mileage range (14,000 to 160,000 miles) and strikes owners repeatedly: one owner's right side CV arm failed again in 2022, five years and 30,000 miles after a 2017 recall repair of the same side. Repair costs typically run $1,125 to $2,000 per incident.
Many owners received recall notice 15V451000 but could not schedule service due to extended parts shortages. One owner was actually told by a Mazda dealer on May 31, 2016, that his car did not need the recall—four days later, the ball joint and control arm broke on a highway on-ramp with his two children and elderly mother in the car.
Related failures include wheel bearing breakage, control arm corrosion with excessive play, and strut/shock leakage on nearly new vehicles. One owner's subsequent transmission and transfer case failures occurred after the initial ball joint incident, though the dealer and manufacturer rejected any connection once mileage exceeded warranty limits.

Failure modes owners describe
Lower ball joint separation/failure
Lower ball joints separate, fracture, or corrode, causing the wheel to detach or turn at extreme angles. Often occurs during low-speed turns or parking maneuvers but poses catastrophic risk at highway speeds.
When: 60,000–160,000 miles; occurs during turns at speeds under 50 mph in most reported cases, though some owners were on highway just before failure
Symptoms owners cite: Loud noise or pop from front suspension; Front wheel turns sideways or detaches; Vehicle jerks and becomes immobilized; Rattling or grinding noise when turning; Loose steering feel; Clicking noise during turns
Repairs/costs cited: Replacement of lower control arms, ball joints, and sometimes axle, CV joint, and suspension hardware. Repair costs $883–$2,000+ per incident; some owners faced repeat failures within 12–30 months and had to pay again.
Recalls/TSBs owners mention: Recall 15V451000 (suspension) issued; parts distribution delays reported. Some dealers cited parts unavailability for extended periods. Mazda dealer service in one case claimed not aware of problem; another dealer blamed wear and tear. One owner's reimbursement claim rejected because non-dealer shop performed repair.
Lower control arm ball joint corrosion and looseness
Ball joints loosen or corrode, leading to excessive play in the suspension and uneven tire wear. Owners report creaking and clunking over bumps.
When: 14,000–178,000 miles
Symptoms owners cite: Creaking noise over bumps and hard turns; Rattling or clunking from front suspension; Excessive and uneven tire wear; Loose steering feel
Repairs/costs cited: Replacement of front lower control arms, sway bar links, and bushings. Costs typically $1,125 reported.
Recalls/TSBs owners mention: Dealer cited as normal wear and tear. Recall 15V451000 applies but parts unavailability delayed service.
Front wheel bearing failure
Wheel bearing breaks, producing a loud roaring sound and risking wheel detachment before noticed.
When: 20,000+ miles
Symptoms owners cite: Loud roaring sound from front wheel; Uneven tire wear
Repairs/costs cited: Wheel bearing replacement and tire replacement.
Strut and shock leakage
Front struts and shocks leak or seep fluid shortly after purchase, signaling potential failure risk.
When: 14,000 miles (reported on nearly new vehicle)
Symptoms owners cite: Visible fluid film on strut/shock; Continued leakage after wiping
Repairs/costs cited: Not repaired in narratives provided; dealer suggested overfill at factory.
Recalls/TSBs owners mention: Dealer claimed overfill at factory and cited it as seepage, not leakage; field rep acknowledged problem but maintained overfill explanation.
Broken rear differential mount
Rear differential mount breaks, requiring replacement.
When: Not specified
Repairs/costs cited: Replacement of rear differential mount.
Axle and CV joint damage
Axles break or CV joints disconnect, often as secondary damage following ball joint failure or as independent failures.
When: Occurs concurrently with ball joint separation
Symptoms owners cite: Loud noise and vehicle immobilization; Wheel detachment
Repairs/costs cited: Axle and CV joint replacement, often bundled with control arm and ball joint repairs.

Common questions
How serious is the suspension problem on the 2008 Mazda CX-9?
It's a meaningful issue. 44 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $900.
At what mileage does the suspension typically fail?
Across the 31 complaints that reported odometer mileage, most suspension failures cluster between 80,000 and 124,300 miles, with the median around 107,300. A quarter of owners report trouble before 80,000; a quarter make it past 124,300. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $900 for suspension repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
