I previously reported the auto breaking system would slam on breaks prematurely. Now it was a factor in an accident where the Mazda CX-50 was rear-ended by a Ram 2500 truck at full speed on the highway. Car is incompaitated and I have suffered injuries.

SERVICE BRAKES
When approaching cars at an intersection, the brake warning does not give any warning, but the cars brake, lock up, and throw me and anything in the seat flying into the floor or side compartment. It was not even necessary to stop that quickly. Totally random and could cause an accident.

TO NTSA - 2025 Mazda CX-50 Premium Turbo Plus - Purchased [XXX] - Less than 2,000 miles Driving north on [XXX] , I took exit [XXX] . When slowing to change to the right-hand lane, it surged then rapidly accelerated. Stepping on the brake did not slow it down, increased acceleration. To avoid hitting cars in my lane, I jumped the curb to the frontage road, continually pumping on the brake. The left front wheel and axle broke off and landed 20 ft away. The vehicle did not slow down; It was stopped by snapping a power pole in half. While trying to grab my purse, two Good Samaritans yelled at me to get out of the car, it was smoking and there were power lines overhead. Miraculously, I walked away. The Mazda salesman we purchased from was notified with photo. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a recall for earlier models regarding "break clunk." The parking break, when sitting overnight in cold or wet environments, makes a loud bang noise when going into motion for the first time. The parking break seems to be sticking to something.

SERVICE BRAKES
Following a professional brake flush at Roger Beasley Mazda Central in Austin, Texas, the left front brake bleeder screw was left loose. This resulted in a significant loss of brake fluid over several days, causing a 'Brake Warning' light to illuminate and a visible reduction in braking performance. A secondary inspection by an independent mechanic confirmed the screw was not tightened, which caused corrosive fluid to leak onto the wheel and compromised the safety of the vehicle.

SERVICE BRAKES
The stock manufacturer brakes on this vehicle have been known for issues. There is a open recall on some models but according to records my vehicle does not fall under the listed VIN numbers associated with the recall. Although my vehicle experiences the same concerns the recall list stats. The brakes seem to intermittently have trouble slowing the car down while ascending slopes and coming to a immediate stop. Often you are forced to use excessive force on the pedal and it still does not come to a complete stop.With the amount of forced iv had to use in the past the brakes should lock up and and create a slide but iv never experienced it. If im am not careful and maintain all attention to what its front of me i fear i will create a accident some day. To often in stop and go traffic or abrupt braking situations i have not been able to assure the vehical will stop . This causes concerns due to always having to travel at slower speeds and politically car repair bills. The life expectancy on the brakes are wearing out quickly. I am not a aggressive driver so i should have no problems with premature brake wear. Iv had the brakes inspected by the same dealership multiple times but they always say there's nothing wrong. The brakes have felt the same since purchasing date. Now we are two years into own the vehicle. The dealership is no help and the manufacture is not as well.

SERVICE BRAKES
I was hearing squealing, as if the brake pads were worn. Called the dealer to ask about parts, was asked to bring it in as it seems too soon for brakes. Upon inspection I was told my rear brakes are worn out at 22k highway miles, and will need rotors too. I asked how this is possible and for a manager whom then stated I could do just the pads. Still no explanation on how, but won't be covered on the warranty. I left without doing the repair because I wanted another mechanic to look at this since you can only get the rear pads from Mazda, so it's expensive. I do need this done and I believe there is a problem with the brake system or the electronic brake you hear engage Everytime you shut the car off. There are also several others complaining about this on Reddit, Google and YouTube, but Mazda seems to be looking the other way in it. I can say this is my 12th Mazda and I have never had one that has needed brakes before 60-70,000 miles and that was with city driving. There is clearly an issue and I'm not the only one.
