The model that was distinguished from the four different electrics of the survey, was the Smart EQ fortwo with a fault rate of 3.5%. In fact, in the list of 128 cars with a thermal engine that TÜV had for this year’s survey, the two-seater electric smart is quite high in reliability, occupying a place in the first third of the list.

Also, it is worth noting that the average failure rate in models with a thermal motor is 4.7%, so the performance of the small electric smart is more than satisfactory.

It is followed by the BMW i3 with a failure rate of 4.7%, which ranks it in the second third of the list. In addition to faulty position lights (small ladder), the i3 often has problems with brake discs. As stated by the CEO of the TÜV Association, Dr. Joachim Bühler, the problem of the i3’s brakes is widespread among electric cars. Energy recovery while driving, taught drivers to use less brakes than those who drive conventional technology cars, thus corroding. That’s why it’s a good idea for electric car drivers to use the braking system frequently.

The fault rate is 10.7%, with one in ten Model S failing in the first general control of the TÜV. In addition to the damage it faces to fog lights and dipped-beam headlights , the Tesla Model S has problems with suspension.
