Saturday, January 29, 2022  Yesterday, the German automotive testing agency TÜV published a special analysis on electric cars. For the first time, enough electric cars had come to the German vehicle inspection agency, commonly known as main inspection, to allow an evaluation for defects and roadworthiness. All in all, contemporary electric cars gave a mediocre impression. The best car in class was the Daimler AG Smart Fortwo with a defect rate of 3.5 percent. Other cars in the special analysis were the BMW i3 with a defect rate of 4.7 percent, the Renault Zoé with a defect rate of 5.7 percent and the Tesla Model S with a defect rate of 10.7 percent. Besides issues with badly adjusted or defective headlights, the Renault Zoé had frequent issues with the car suspension. "A common problem of electric cars are the brakes, which may fall into disuse due to energy recuperation and thus can get corroded more easily", said Dr. Joachim Bühler, executive director of the TÜV association. He explained: "If possible, owners of electric cars should aim to use the brakes each time the car is used and also have the brakes taken care of regularly." Corrosion of the brakes was also mentioned as a problem of the BMW i3 in the TÜV results. Tesla already had known suspension problems and had to make recalls in the United States and in China earlier. Another chronic problem of Tesla cars was reported to be water entering the spotlights. The TÜV results reviewed 9.6 million cars and 128 different car models in the three years old group, but only about 1000 to 2000 electric cars of each type. In the TÜV results both the Renault Zoé and the Tesla Model S would be in the lowest third, if compared to conventional cars with combustion engines. Gustavo Henrique Ruffo.
