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.

The failure pattern owners describe
The front suspension on 2008 CX-7s shows a clear pattern of control arm and ball joint failures. Two owners experienced sudden fractures of the front lower control arm while driving: one at low speed on a neighborhood street heard a loud bang, the corner dropped, and steering was lost completely; another heard a popping noise at 20 mph and found the arm broken. Both events created secondary damage to tie rods and wheel alignment. A third owner's ball joint failed before the recall could be performed, requiring additional repairs.
The manufacturer issued recall 16V593000 to replace the lower control arms and ball joints, but parts became unavailable almost immediately after notices were sent in August 2016. By late 2017, owners were still waiting with no parts in stock at dealers and no estimated delivery date from Mazda. Owners repeatedly called both dealers and Mazda with no resolution. One owner waited six months unable to drive front passengers due to the related airbag recall also awaiting parts. One owner had privately repaired the control arm before the recall was issued but Mazda refused reimbursement and demanded bank proof despite an invoice marked "Paid Visa." After the recall was finally completed on another vehicle, the replaced ball joint was loose again within 13 months, yet Mazda provided no warranty on the recall-replaced parts.
Additional reported suspension symptoms included popping and clicking noises from the front, steering wheel vibration at 60 mph on vehicles with unrepaired recalls, and unusual tire wear (needing replacement at 24,000 miles with wheel shake on braking). No owner data bridges these symptoms to the control arm issue, but the timeline overlap is notable.

Failure modes owners describe
Front Lower Control Arm Fracture
Front lower control arm cracks or fractures, causing sudden loss of steering control and suspension collapse. One owner experienced complete loss of steering when the left front control arm broke at low speed on a residential street; another reported a loud popping noise from the front at 20 mph followed by fracture discovery. Cascading damage to tie rods, drive shaft, and wheel alignment results when the arm fails.
When: 130,000–unknown mileage; failures reported between 2016–2017 calendar years
Symptoms owners cite: Loud popping or banging noise from front suspension; Sudden loss of steering control; Front corner of vehicle drops; Wheel rotates to 90-degree angle relative to fender; Vehicle pulls to one side
Repairs/costs cited: Owners cite replacement of lower control arms; one owner paid privately before recall and was later denied reimbursement. Repair costs not stated for fracture replacement itself, but secondary damage (tie rods, drive shaft) significantly increased total repair expense.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000 issued for lower control arm replacement. Multiple owners reported recall parts remained unavailable for extended periods (months to over a year after recall notice). One owner repaired before recall was issued and Mazda denied reimbursement despite having paid invoice. No warranty coverage provided on recall-replaced ball joints after one year.
Loose/Premature Ball Joint Failure After Recall Repair
Ball joints replaced under recall (16V593000) become loose again within 12 months. Owner reported left ball joint already loose approximately 1.3 years after recall repair on 01/25/2017. Indicates either defective replacement parts or the underlying design issue was not fully resolved.
When: Approximately 1 year post-recall repair (January 2017 repair); no stated mileage
Symptoms owners cite: Ball joint loose after recall replacement
Repairs/costs cited: Ball joints were replaced under recall at Morrie's Chippewa Valley Mazda, Lake Hallie, WI. No warranty provided on the replacement parts by Mazda despite this being a factory defect recall.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000. Mazda stated no warranty on recall-replaced parts.
Recall Parts Unavailability (16V593000)
Widespread parts shortage for suspension recall 16V593000 (lower control arm/ball joint replacement). Owners waited months to over a year after receiving recall notice with no parts available and no estimated arrival date. Dealers consistently reported to customers that parts were not in stock and manufacturer could not provide timeline. Multiple owners stated manufacturer exceeded reasonable time frame for recall remedy.
When: Recall notices issued August 2016–January 2017; parts remained unavailable through at least August–December 2017
Symptoms owners cite: Unable to schedule recall repair due to parts shortage; No estimated parts delivery date provided; Repeated calls to dealer and manufacturer with no resolution
Codes mentioned: NHTSA Campaign 16V593000
Repairs/costs cited: No repair possible until parts available. One owner reported 6+ months without front passenger seat available due to related airbag recall also awaiting parts.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000. Manufacturer unable to confirm parts availability timeline. Multiple owners stated Mazda stated they 'could not do anything about it.' One dealership indicated Mazda placed a hold on all suspension repairs pending permanent parts solution (vs. temporary fix).
Steering Vibration at Highway Speed
Steering wheel vibrates without warning while driving at approximately 60 mph. Symptom occurred in at least one vehicle with known suspension recall pending but unrepaired due to parts unavailability. Likely related to control arm or ball joint wear but not independently diagnosed.
When: Unknown mileage; approximately 150,000 miles on one vehicle
Symptoms owners cite: Steering wheel vibration at approximately 60 mph
Codes mentioned: NHTSA Campaign 16V593000
Repairs/costs cited: Vehicle not diagnosed or repaired due to recall parts unavailability.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000 parts unavailable.
Abnormal Popping Noise from Front Suspension
Popping or clicking and humming sounds emanate from the front passenger side or general front suspension area. Two owners reported these noises while unrepaired suspension recalls (16V593000) were pending due to parts shortage.
When: Mileage unknown; one vehicle at 80,000 miles
Symptoms owners cite: Loud popping sound from front driver side wheel area; Clicking and humming noise from front passenger side
Codes mentioned: NHTSA Campaign 16V593000
Repairs/costs cited: Noises not diagnosed or repaired because recall parts unavailable.
Recalls/TSBs owners mention: NHTSA Campaign 16V593000 parts unavailable.
Tire Wear Acceleration
Front tires wear excessively fast. One owner reported Goodyear 235/60/18 tires worn to replacement at 24,000 miles, whereas same owner's Dodge Ram 2500 achieved 70,000 miles on tires. Owner also reported wheel shake when braking and vibration at 65 mph.
When: 24,000 miles on CX-7 vs. typical 70,000 miles on larger truck
Symptoms owners cite: Rapid tire tread loss; Wheel shake when applying brakes; Vibration at highway speed (65 mph)
Repairs/costs cited: New tires required at 24,000 miles. Owner described tire cost as excessive relative to competitor vehicle.

Common questions
How serious is the suspension problem on the 2008 Mazda CX-7?
It's a documented issue but not catastrophic. 38 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 11 complaints that reported odometer mileage, most suspension failures cluster between 91,000 and 150,000 miles, with the median around 122,984. A quarter of owners report trouble before 91,000; a quarter make it past 150,000. 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.
