Filed Jan 15, 2026 · Brakes · GA · crash

Description On 12-15-2025, in 18°F weather, the vehicle was parked on a residential sloped driveway with the manual parking brake fully engaged. While the driver was outside the vehicle, the parking brake system failed to hold the car’s weight. The vehicle rolled backward, crashed through a wooden railing, teetering on a 4-foot retaining wall, and came to rest over a culvert. Two young children were inside the vehicle at the time of the failure. Component Failure & Availability: The manual parking brake system failed to provide sufficient holding force to secure the vehicle. The rear brake calipers are currently available for inspection. Safety Risk: The safety of the two children inside the vehicle was put at extreme risk due to the unexpected movement of the car. This failure matches the exact conditions and consequences described in Safety Recall 1217F (the federal safety agency Campaign 17V‑393), which states that "unexpected movement of the vehicle if parked on a slope" increases the risk of a collision. Reproducibility & Confirmation: The failure occurred under the specific environmental triggers (cold temperature and slope) identified in the manufacturer's own safety recall documentation. However, the manufacturer has officially refused to authorize the internal teardown of the actuator shafts—the only diagnostic method capable of verifying the rust and sliding resistance that causes this loss of holding force. Inspections: The vehicle has been visually inspected by an authorized dealership and insurance representatives. The manufacturer has declined the necessary internal mechanical diagnostics to verify the internal defect. Warning Symptoms: There were no warning lamps, messages, or symptoms prior to the failure. The parking brake felt fully engaged at the time the vehicle was parked.

My rear brakes always seem to be dragging. They make a loud grinding noise as I exit my neighborhood. After driving a while, the noise is quieter but still noticeable. I am afraid of it locking up while driving and causing me to lose control.

I've had to replace back brakes twice in 4 years. Now calipers have gone out which ruined rotors and pads. It looks like others have had the same issue with calipers not working properly and wearing the brakes prematurely.

I started noticing a squeal from my rear brakes that would occur at the beginning of driving (not while braking) then go away after 1 or 2 stops. About a week and a half later, the day I used my handbrake to park, after my 25 minute commute home I noticed a hot metal smell. I put my hand up to my driver side rear wheel and felt intense heat from the brakes. Saw the rotors were dug in. I bought rear brakes and rotors and changed them out myself. The parking brake actuator shaft was stuck, binding the brakes on both rear calipers. The metal around the boot of both shafts on the caliper look wet. The piston of the caliper was easily rotated back in after unbinding the parking brake actuator shaft. Parking brake now is unhooked due to it being unsafe. This happened on both parking brake actuator shafts on the rear calipers after only 24,900 miles.

Like many other mazda 3 owners, I have had water enter my calipers and bind, leaving brakes activated on the rotors wearing down the brakes faster than normal. Approx 65,000 miles on my car and I am currently getting my third set of brakes and rotors installed on my vehicle, with new calipers that is not covered under the recall. After contacting mazda, my VIN specific does not qualify for this recall. This issue is known from mazda and should be extended to all models.

Passenger side rear brake caliper does not retract properly and wears out brake pads quickly. This should not hapen at less than 50,000 miles. I have seen numerous complaints online and there is a recall for this year, but it does not include my VIN.
