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 6 model years of Mazda CX-7 we track for suspension problems, this one carries the most owner complaints on file — 55.
Owners have filed 55 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 report front lower control arms and ball joints separating or fracturing without warning, typically during routine driving, turning, or acceleration. Several describe a sudden loud pop followed by complete loss of steering control and the vehicle coming to a stop in traffic—a serious safety hazard. Corrosion from winter salt and water intrusion into the ball joints is cited as the root cause in northern climates. Repair costs run $1,300–$1,490 for control arm replacement plus related suspension work.
Premature tire wear—cupping and feathering on all four tires within 5,000 miles—appears linked to suspension design issues. Repeated dealer rebalancing and realignment do not resolve the problem. Dealers sometimes increase tire pressure above manufacturer spec, worsening center wear.
Strut and strut bearing noise during low-speed turns and backing up has persisted even after parts replacement. A 2009 manufacturer notice about this issue exists but dealers do not routinely disclose it.
The suspension recall (Campaign 16V593000) issued in 2016 has left owners unable to complete repairs for over a year—sometimes longer—due to parts unavailability. Manufacturers refuse to provide estimated delivery dates, frustrating owners who receive recall notices but cannot schedule service.

Failure modes owners describe
Lower Control Arm and Ball Joint Separation/Fracture
Front lower control arm separates, fractures, or becomes loose, often accompanied by ball joint detachment. Owners report loud popping sound during acceleration, turning, or normal driving. Wheel may go sideways or vehicle loses steering control. Multiple complaints cite corrosion of ball joints from winter road salt exposure, leading to looseness in both front ball joints.
When: Typically 60,000–193,000 miles; one case noted 8 years of ownership
Symptoms owners cite: Loud pop or popping noise during acceleration or turning; Loss of steering control; Front wheel positioned sideways or detached; Vehicle cannot move; Vibration and knocking noise while driving; Vehicle veers left or right without warning; Rattling noise from front
Repairs/costs cited: One owner paid $1,300 to repair axle shaft, lower control arm, tie rod, sway bar, and alignment; additional $500 for front passenger lower control arm and ball joint replacement. Another owner cited $1,490 repair cost for control arm detachment.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000 (Suspension) – parts unavailable for extended period. Owners note this defect mirrors CX-9 recall 8515G; CX-7 was not included in that recall.
Abnormal Tire Wear (Cupping, Feathering)
All four tires exhibit premature cupping and feathering wear within first 1,000–5,000 miles. Repeated dealer rebalancing and realignment do not resolve the issue. Dealer incorrectly increased tire pressure above manufacturer specs. At least one case attributed wear to front suspension design flaw.
When: Less than 5,000 miles; another case noted worn tires requiring replacement 20,000 miles after initial replacement
Symptoms owners cite: Cupping and feathering on all four tires; Vibration at highway speeds; Rough ride feel at lower speeds; Tire pressure warning light illuminated
Repairs/costs cited: One owner replaced all four tires at cost of nearly $800; issue persisted. Dealer recommended repeated rebalancing and realignment but did not address underlying suspension design.
Wheel Speed Sensor Failure and Rear Wheel Bearing Rust
Rear wheel speed sensors fail, allowing water intrusion and causing rust damage to rear wheel bearings. Owners initially misdiagnosed the noise as a tire issue.
When: Unspecified mileage in one case; owner had vehicle for 18 months before diagnosis
Symptoms owners cite: Oppressive amount of road noise at all speeds on all road surfaces; Noise persists after tire replacement
Repairs/costs cited: All four wheel bearings were replaced after wheel speed sensor failure discovered.
Strut and Strut Bearing Noise
Rubbing or dry, labored sound from suspension/steering area, most notable during low-speed turns and backing up. Dealer replaced strut bearings without resolving the issue. Later recommendation was to replace both struts and strut bearings, though latter was still under warranty. Owner had encountered a 2009 manufacturer notice regarding this problem, but dealer did not disclose it.
When: Before 67,000 miles; issue first manifested by 2013 inspection
Symptoms owners cite: Rubbing or dry, labored sound during low-speed turning; Sound noted when backing up and turning; Sound not reproducible at dealership
Repairs/costs cited: Strut bearings replaced in 2013; problem persisted. Dealer later recommended strut and strut bearing replacement.
Recalls/TSBs owners mention: 2009 manufacturer notice about this problem exists but was not disclosed to owner.
Coil Spring Failure (Recurring)
Coil spring fails and must be replaced. After repair, failure recurs and springs must be replaced again.
When: Around 100,000 miles
Symptoms owners cite: Check engine warning illuminated
Repairs/costs cited: Coil springs replaced twice at dealer.
Suspension Recall Parts Unavailability
NHTSA Campaign 16V593000 (Suspension) recall issued, but parts for repair unavailable for extended period. Owners unable to schedule recall repairs; manufacturer unable or unwilling to provide estimated delivery date for parts. Multiple complaints cite 'Parts Distribution Disconnect' and manufacturer's failure to supply remedy within reasonable timeframe.
When: Recall notices issued in 2016; parts still unavailable as of 2017–2018 in some cases
Symptoms owners cite: Recall notice received but parts unavailable; Manufacturer cannot provide estimated date for parts availability
Repairs/costs cited: No repairs completed due to parts unavailability. One owner requested reimbursement and right-side control arm repair.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000 (Suspension) recall; parts unavailable for months/years after recall notice. Manufacturer exceeded reasonable repair timeframe.

Common questions
How serious is the suspension problem on the 2007 Mazda CX-7?
It's a documented issue but not catastrophic. 55 complaints have been filed. Repairs average $900 and most owners catch it before it causes a breakdown.
At what mileage does the suspension typically fail?
Across the 24 complaints that reported odometer mileage, most suspension failures cluster between 72,000 and 148,000 miles, with the median around 109,000. A quarter of owners report trouble before 72,000; a quarter make it past 148,000. 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.
