Driver’s side seat belt would not retract.

I was denied work on a network issue recall 3 separate times at the dealership I bought the car. The first time I was told it was because of a smell. If I clean the car, they will fix it. I noticed after they were in the car my backup camera didn’t work which I also thought might be a recall but found out it wasnt. I went ahead and cleaned it twice. I came back they alleged it smelled like cat litter and urine. I asked to speak to someone else because there was nothing in my car and I know it…

While driving on the highway (50mph), the sunroof had shattered unexpectedly. The sunroof itself was not open, but the visor was open so the glass fell into the car, onto the driver, the passenger and into the backseats. The glass shattering sounded like a gunshot which startled us while on the highway, and the broken glass cut the driver.

Low pressure fuel pump failure with 75,575 miles on odometer. Fuel pump completely seized. Car was parked at a retail location and would not start. Upon troubleshooting, mechanic was able to determine the low pressure pump was not delivering fuel. Pump was replaced. Faulty fuel pumps could lead to hazardous conditions as they are mounted within the fuel tank. I feel this is too early in the vehicles life for this component to have completely failed.

The driver-side sun visor has suffered an internal mechanical failure where the internal plastic tension components have cracked under normal use. As a direct result, the sun visor will not stay up and randomly drops down completely unprompted while the vehicle is in motion. This creates an immediate, sudden, and dangerous visibility hazard by blocking my forward view of the road while driving.Mazda has formally recognized this specific engineering defect across 2019–2025 Mazda 3 vehicles in…

The fuel tank leaks fuel at a full tank and smells of gas in the cabin until about 3/4 tank. Car was dripping a large puddle of gas inside of a parking garage. Problem has been reproduced by my mechanic even after replacing the fuel pump retaining ring. It has not been inspected by the manufacturer or police. CEL did not come on until recently reporting a very small EVAP leak. Inside the car and the surrounding area would smell of gasoline even if there was no leak in the ground.
