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
Among the 8 model years of Mazda Mazda3 in our records for suspension problems, this one ranks #3 by owner-complaint volume.
No new NHTSA suspension complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
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 2007 Mazda3 vehicles report a cluster of suspension issues, with tire wear and alignment problems at the top of the list. Multiple owners experienced premature inside-edge tire wear, with one noting visible steel cord at 30,000 miles and another replacing six tire sets in a year. Dealers confirm excessive negative camber in the front suspension is responsible. The rear suspension lacks adjustment capability—one dealer quoted $500 for an aftermarket alignment kit, and Mazda claims the non-adjustable design is intentional for stability.
Clunking and knocking noises appear early in vehicle life. Owners report sounds when turning, hitting bumps, or crossing railroad tracks. Dealers have repeatedly tried replacing sway-bar bushings, bolts, engine mounts, strut bearings, and control rods without lasting fixes. One case involved seven separate component replacements that made the problem worse instead of better.
Early component failures are also common. Hub bearings needed replacement at 37,000 miles—unusually soon compared to other vehicles. One owner's control arm bent without external cause, warping the front geometry by 30 degrees and creating safety concerns. Another owner's axle rubbed against engine metal at 98,000 miles, requiring replacement.
Dealers often identify problems but decline to repair them. Worn engine mounts and leaking struts were diagnosed but left unfixed. Out-of-warranty vehicles face refusal to address manufacturer defects. Some complaints remain unresolved after multiple dealer visits and escalation to Mazda.

Failure modes owners describe
Premature tire wear and excessive negative camber
Multiple owners report abnormal tire wear, particularly on the inside edge of tires, appearing well before normal service life. One owner observed steel cord visible at 30,000 miles; another replaced six tire sets within a year due to inside-wall wear. Dealers and owners have identified excessive negative camber in the front suspension as the root cause. One dealership confirmed rear wheels cannot be aligned and offered a $500 aftermarket kit to address it. Mazda stated the rear suspension design is intentional for stability.
When: 30,000–50,000 miles for front wear; accelerating thereafter
Symptoms owners cite: Inside edge of tires wearing faster than outside; Tread separating at premature mileage; Steel cord visible before expected tire life; Shaking while driving over 40 mph; Tire pressure warning light cycling on and off
Repairs/costs cited: Tire replacement (multiple sets per owner); one owner quoted $500 for aftermarket rear alignment kit. No factory alignment correction available per dealer.
Recalls/TSBs owners mention: Mazda stated the rear suspension design is intentional and does not warrant correction; vehicle not covered under NHTSA campaign 07V295000.
Clunking and knocking noises from suspension
Multiple owners report clunking or knocking sounds during turns, bumps, railroad tracks, or normal driving. Root causes identified include loose rear sway-bar bolts with bent pins, worn engine mounts, leaking struts, and strut bearing issues. One owner's vehicle required replacement of motor mount, rear sway-bar bushings, front strut-bar bushings, front sway bar, stabilizer plate, control rod, and upper strut bearing—multiple failed repair attempts made the problem worse.
When: Early ownership (3–4 months) to mid-life; one case at 50,000 miles
Symptoms owners cite: Hard knocking noise when turning; Clunking over bumps, railroad tracks; 'Clap' sound passing over dips in road; Worsening drivability and handling
Repairs/costs cited: Loose sway-bar bolts retightened and bushings replaced; strut replacements attempted multiple times without resolution in one case. Dealers unable to pinpoint cause in some instances.
Bent or defective lower A-arm (control arm)
One owner's vehicle developed a bent lower A-arm with no external cause cited. Dealership identified material failure. The bent A-arm caused front-end geometry to be severely out of phase by 30 degrees, creating undue stress on the lower ball joint and risk of premature breakage. Separation of the A-arm from the spindle poses safety risk. Vehicle was out of warranty; manufacturer refused repair.
When: Timing not stated; noted at unspecified mileage
Symptoms owners cite: Hard knocking noise when turning (result of bent arm); Severely misaligned front-end geometry (30 degrees out); Undue stress on lower ball joint
Repairs/costs cited: New A-arm and possibly related components needed; not repaired due to out-of-warranty status.
Recalls/TSBs owners mention: Manufacturer refused to repair due to vehicle being out of warranty.
Worn engine mount and struts
Diagnostic testing detected worn engine mounts and leaking struts during suspension-related service calls. One owner's vehicle exhibited front-end vibration and engine stall at highway speed. Dealers identified worn engine mounts and leaking struts but did not replace them despite diagnostic findings.
When: 50,000 miles
Symptoms owners cite: Front-end vibration; Engine stall at 65 mph; Strut fluid leakage
Repairs/costs cited: Engine mounts and struts identified as worn/defective but not replaced by dealer.
Loose or unstable struts
One owner reported unstable and noisy struts; another noted front struts that had failed. A third complaint referenced clunking attributed to strut components.
When: Timing varies; one case at 37,000 miles with front-end parts already replaced
Symptoms owners cite: Noisy struts; Unstable ride; Clunking sounds
Repairs/costs cited: Strut replacements performed; one owner noted front hub bearings and intermediate shaft also required replacement at 37,000 miles.
Front hub bearing wear and failure
One owner with 37,000 miles required front hub bearing replacement. Owner noted this is unusually early for such wear compared to other vehicles with over 100,000 miles.
When: 37,000 miles
Symptoms owners cite: Grinding noise in front hubs
Repairs/costs cited: Front hub bearings replaced; intermediate shaft also replaced at same service.
Axle rubbing against engine metal
One owner reported the axle rubbing against a piece of metal in the engine, causing malfunction. Dealer diagnosed the need for axle replacement.
When: 98,000 miles
Symptoms owners cite: Axle malfunction due to rubbing
Repairs/costs cited: Axle replacement required; vehicle was not repaired.
Recalls/TSBs owners mention: Manufacturer not made aware of the failure.

Common questions
How serious is the suspension problem on the 2007 Mazda Mazda3?
It's a documented issue but not catastrophic. 11 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 9 complaints that reported odometer mileage, most suspension failures cluster between 30,000 and 92,317 miles, with the median around 50,000. A quarter of owners report trouble before 30,000; a quarter make it past 92,317. 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.
