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.

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
Front struts fail prematurely on these Mazda3s, sometimes as early as 45,000–50,000 miles. Multiple owners report the struts lasted far shorter than expected, even after careful maintenance. One owner hit a pothole, and the impact disclosed a busted front strut; another heard grinding and found a rear strut mount cracked completely across at the bolt holes. Rear shock mounts also crack and bust out of the wheel well.
Motor mounts are a serious problem. Owners report the transmission motor mount breaking catastrophically, causing the engine to lunge forward, shear bolts on other mounts, and damage the front suspension—a failure that rendered the car unable to steer or propel itself. One owner discovered the passenger-side motor mount in multiple pieces, discovered only after months of misdiagnosis; another was told by a Mazda dealership their motor mount was broken but refused to show proof until months later. A recall exists for motor mounts on some Mazda3s, but not all affected cars are included.
Premature tire wear is endemic. Even with regular rotation, balancing, and alignment, tires wear bald on the inside by 17,000–30,000 miles. Owners cite "factory spec" negative camber settings as the culprit. Alignment problems persist despite dealer fixes; one owner went through two tire sets in 50,000 miles and faced a $900 alignment repair Mazda could not explain.
Rear trailing arms dry out and malfunction, causing bushing failure and inside tire deterioration. Rust is severe on underbodies, creating safety concerns when lifting the car.

Failure modes owners describe
Front struts premature failure
Front struts fail well before normal service life. One owner's struts failed at approximately 45,000–50,000 miles after a pothole strike disclosed the defect. Mechanics and dealers confirmed the struts should have lasted far longer.
When: 45,000–50,000 miles and beyond
Symptoms owners cite: Loud noise and terrible vibrations after strut replacement; Clunk noise when hitting uneven road surfaces
Repairs/costs cited: Both front struts replaced; one report of replacement costing several hundred dollars in labor and parts
Motor mount catastrophic failure
Transmission motor mount breaks and causes engine to lunge forward, sheering bolts on other motor mounts and severely damaging front-end suspension components. One owner reported the motor mount in multiple pieces; another experienced complete loss of steering and propulsion at 50 mph on a freeway off-ramp.
When: Unknown mileage in one case; another at approximately 45,000–50,000 miles
Symptoms owners cite: Loud grinding and crashing noises from under hood; Difficult to steer; Car will not propel itself; Vibrations in cabin
Repairs/costs cited: Repair estimate approximately $3,000 for transmission motor mount, other motor mount bolts, and suspension damage. One owner had motor mount replaced in January after months of misdiagnosis.
Recalls/TSBs owners mention: Mazda has recalled some Mazda3s for motor mount problems, but not all affected vehicles are included in recall
Rear shock and strut mount cracking and failure
Rear shock mounts and strut mounts crack and break, especially at bolt holes. One mount cracked completely across from bolt to bolt and could fail at any time. Rust accumulation contributes to breakdown.
When: Unknown specific mileage; one report mentions rust issues at higher mileage
Symptoms owners cite: Banging noise from rear of car; Clunk noise when driving over bumps or uneven road; Shock mount broken and cracked at bolt holes
Repairs/costs cited: Rear shock mount replacement required; one owner concerned identical failure will occur on opposite side
Premature inside tire wear and misalignment
Tires wear prematurely on the inside edge, becoming bald by 17,000–30,000 miles despite regular rotation, balancing, and alignment. Owners attribute this to aggressive negative camber in factory specifications. Multiple owners report going through multiple tire sets in 50,000 miles.
When: 17,000–30,000 miles
Symptoms owners cite: Inside tread completely bald; Uneven tire wear on inside edge; Rubbing sound when turning hard right; Deep gouges cut on inside of front tires
Repairs/costs cited: Four new tires at 21,000 miles; second set of tires needed shortly after. One owner replaced two sets of tires in 50,000 miles. Another faced $900 front alignment repair that dealer could not explain.
Recalls/TSBs owners mention: Mazda dealership and Mazda offices unwilling to address the problem or find solution in one case
Rear trailing arm and bushing failure
Rear trailing arms dry out and malfunction. Bushing failure causes tires to deteriorate on the inside. Reported at 89,000 miles during routine maintenance.
When: 89,000 miles
Symptoms owners cite: Rear trailing arms dry and malfunctioned; Inside tire deterioration
Repairs/costs cited: Rear lower trailing links and all four tires needed replacement; vehicle was not repaired per this report
Severe underbody rust compromising structural integrity
Underbody rusts severely, with chunks falling off rear disks and shock mounting plates. Rust compromises structural integrity to the point the owner fears the car will fall apart when lifting it to change a tire.
When: Unknown specific mileage; appears to be age-related deterioration
Symptoms owners cite: Underbody nothing but rust; Chunks of rust falling from rear disks and shock plate; Shock rear driver side broken out of place due to rust; Muffler rusting and falling
Repairs/costs cited: Owner reports fear of changing a tire due to lack of safe grip points; structural integrity compromised
