While parked on a slight downhill grade, gasoline started leaking and created a significant puddle on the ground. No warning lamps, messages or other symptoms. An independent service center ran numerous tests over two days, including a smoke test. Diagnosis: There is a hole in top section of fuel tank and the fuel tank needs replaced. Recommendation was to not drive vehicle with fuel tank over half full. Due to the potential of leaking fuel in the presence of a hot ignition source increasing the risk of fire, driving the vehicle long distance with defective fuel tank appears to represent an unreasonable safety risk. Unfortunately, the vehicle is currently 300 miles from home. Mazda’s Mexican-made plastic fuel tank specifically required for our vehicle’s VIN is not currently available. (Mazda makes a similar metal fuel tank in [XXX] which will not fit.) Mazda has an estimated three-month backlog in [XXX] for the fuel tank. Still awaiting repair due to lack of availability of the appropriate fuel tank. Major safety recall the federal safety agency 16V684000 for the 2015 Mazda3 addresses a manufacturing defect where a fuel tank weld could fail, leading to fuel leaks and a potential fire. Recall is for vehicles produced between 12/4/13 – 9/18/15. Our vehicle was manufactured 02/2015 in [XXX] . However, recall is limited to three specific series of VINs and our vehicle falls in the gap between subject VIN ranges. A recent the federal safety agency complaint XXX (1/27/26) has the same issue: fuel tank leak, but not within range of recall VINs. It seems that the list of affected VINs included in recall 16V684000 should be expanded to include additional Mexican manufactured vehicles potentially with the same issue. Or create a new recall. Having a hole in the top of a plastic fuel tank securely mounted to the vehicle is unexpected through normal wear and tear. Any fuel leakage increases the risk of fire. the federal safety agency should investigate if this is due to a defect in Mazda’s manufacturing process.

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.

I had purchased a car through Facebook Marketplace after talking to the seller and seeing a CarFax report on the car we decided to purchase it. After coming home the following day I look closer at the documents and realized the CarFax did not match the VIN of the car I purchased. After looking up the CarFax with the VIN on the car I purchased I saw that the person who sold me the car had rolled back the odometer.

The vehicle automator mileage was changed. The original mileage reading is over 200,000 mi. While the dashboard mileage only reads 90,780 mi. I was unaware of this until I went to the DMV to do a title transfer. The private seller is now nowhere to be found from Facebook marketplace and has blocked me but I do have receipts of everything

The Infotainment System will randomly change radio stations while driving, or start scanning through the various system menus, and on at least in one case, started randomly making phone calls from a connected phone. This creates a major distraction while driving. This has been looked at by the dealership and would cost $1500 for the system repair. I understand that this is a known problem.
