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 NHTSA 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 NHTSA 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. NHTSA should investigate if this is due to a defect in Mazda’s manufacturing process. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR

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 (NHTSA 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 contact owns a 2015 Mazda Mazda3. The contact received notification of NHTSA Campaign Number: 23V487000 (BACK OVER PREVENTION). However, the dealer refused to complete the recall repairs due to the vehicle having a Salvage Title. The contact stated that the rearview camera displayed a black screen while the vehicle was in reverse(R). The contact stated that the failure obstructed the driver's visibility, which prevented the driver from safely operating the vehicle. The manufacturer was made aware of the issue and referred the contact back to the dealer. The vehicle remained unrepaired. The failure mileage was approximately 86,000.

The G-level part cannot be used to repair a vehicle built with the H-level. The H-level part can be used to repair a vehicle built with the G-level, but the ball joint retainer (d- Code 34-552) has been eliminated.

This SA supersedes the previously issued SA(s) listed below. The changes are noted in Red. SA-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 01-008/23 06/05/23 Some vehicles may exhibit rattling noises from the engine compartment and oil leakage from the drive belt auto tensioner.
