Tesla's brake failure reasons are as follows: 1. Brake acceleration: There is a communication issue between the brake pedal and the brake-by-wire system, causing the vehicle to accelerate instead of decelerating when the brake is pressed, leading to brake system failure. 2. Design defect: The Bosch iBooster has a design flaw. While Tesla vehicles can actively engage the brake-by-wire system when sensors detect danger, there can still be errors, delays, or interruptions in electrical signal transmission, resulting in brake failure or sudden acceleration. 3. Bug: Tesla modified the iBooster to 'perfectly match' its own AutoPilot system, but this introduced a bug that can cause brake failure.

As someone who has long followed electric vehicles, I believe the causes of Tesla's brake failures can be varied. The most noteworthy issue is software-related—Tesla's electronic control systems are highly complex, and sometimes software updates can introduce new bugs, leading to delays in brake signal transmission or incorrect responses. Sensor failures are also common; for instance, when radars or cameras used to monitor vehicle speed and road conditions malfunction, the system cannot accurately determine when emergency braking is needed. Additionally, driving habits such as mistakenly pressing the accelerator pedal or over-reliance on autonomous driving assistance can easily lead to pedal confusion, especially when distracted. Environmental factors like rain or snow affecting sensor readings may cause the regenerative braking system to stop working. It is recommended that owners regularly perform system diagnostics to check software health, install dash cams to capture event data, and ensure safe driving.

Having driven a Tesla for several years, I personally believe that brake failure is primarily related to the control system. Issues may arise with the electronic braking components: when software updates cause code conflicts or hardware incompatibility, the brake pedal input response can become slow or even fail. Sensor malfunctions, such as problems with wheel speed or distance sensors, may transmit incorrect data to the computer, preventing automatic braking from engaging. Physical component factors should not be overlooked either—worn or contaminated brake discs and pads, or hydraulic system leaks can reduce braking efficiency at high speeds. A friend of mine experienced this issue, and they later improved their maintenance routine: inspecting the braking system every six months and promptly cleaning the sensor areas. Driving in rainy conditions requires extra caution, ensuring good tire condition for effective braking.

As an automotive enthusiast with a focus on technical details, I can explain that Tesla's brake failure issues often stem from integrated system problems: when the transition logic between regenerative braking and friction braking malfunctions, the software may fail to promptly activate physical brake components. Faulty sensors like accelerometers or gyroscopes can misjudge vehicle dynamics, causing delayed responses. Physical wear such as thinning brake pads or insufficient fluid levels can also degrade braking performance. Risks increase during extreme driving or after software updates; it's advisable to use the owner's app to monitor system warnings and avoid frequent hard braking to prevent accelerated hardware wear.
