THE TeslaElon Musk’s car maker, is experiencing a problem with its vehicles Model Y and Model 3. Some of these models are braking abruptly at high speeds on highways. 354 complaints of the problem were reported, with no fatal accidents, in the last nine months.

Hold the p*t* m*rd*!

The steering assistance system Tesla will be investigated by the US government. Surprise braking happens when drivers activate Cruise Control (which maintains the desired speed) or Autopilot, Tesla’s own power steering technology. Autopilot accelerates, brakes and changes direction while traveling on highways. But owners of Model Y and Model 3 reported cases in which vehicles braked abruptly without any obstacle or problem ahead. There were no accidents because of the glitch, but just barely. One of the drivers who were victims of the problem said that his Model 3 braked abruptly on the highway, reducing from 128 km/h to 64 km/h (half the speed. He quickly took control of the car and entered the opposite direction to prevent a Toyota Tundra truck (the company’s largest and which should reach the Brasil), which was close to the Tesla, hit its backside.

You don’t want one Tundra of more than 2.5 t hitting more than 100 km/h in its 1.5 t “cart”.

Tesla recalls

THE Tesla already performed eight recalls since November 2020, totaling over 1,000,000 cars to be repaired or “fixed”. In November 2020, Tesla issued a ticket for 9,136 Model X (years 2015 and 2016). In 2021 alone, the manufacturer carried out five recalls

In February, it recalled 135,000 Model S sedans (years 2012-2018) and Model X SUVs (years 2016-2018). The reason was not serious, but problems with the on-board computer processor caused the touchscreen to fail. Also in February, 12,300 Model Xs were recalled in Germany due to scratches from the car’s finishes coming off. The cause was a problem with the glue of the pieces.

In June, there was already a more dangerous case: 6,000 Model 3 (years 2019-2021) and Model Y (2020-2021) had problems with the brake caliper screws. In October, more problems with the screws of the Model 3 and Model Y, this time in the parts located in the front suspension of the vehicles. Here, more than 3,000 cars were called.

To end 2021, Tesla recalled an additional 475,000 vehicles. The front trunk lid of 119,009 Model S could open while the car was moving. While 356,309 Model 3 were part of the same recall because of the hood of the rear trunk: the opening and closing of the hood wore a cable from the rear camera, which leads to the uselessness of functionality and loss of vision of the reverse maneuver on the screen.

In early February, Tesla summoned the owners of the Model X, Model S and Model Y. 53,822 cars will have to be upgraded to change the “Assertive” mode of self-driving. This mode allows the vehicle to drive faster, not just by speed, but by some actions. The action that will be corrected is what is called a rolling stop in English: starting the car without it having come to a complete stop. The American “DNIT” considers this practice unsafe.

The latest, earlier this month, called on 578,607 cars to upgrade the manufacturer’s custom audio horn system.
