      German TUV Reliability Report

      Those numbers are very misleading, as it includes rust on the brakes.

      EVs don’t use their brakes as often due to regen, and vehicles with one pedal driving where you can come to a complete stop without using the brakes, use it even less.

      A large portion of these failures are from some rust appearing from lack of using the brakes. Using the brakes more frequently, or intentional aggressive braking would clear the rust, but it’s a fail if it’s there when you take it in.

      That’s not to say there aren’t other problems, but it’s not as bad as the dead last 14.7% makes it look, and it’s not wholly about poor quality as the report implies, as that isn’t a quality problem.

      Tesla has some of the better one pedal driving and more aggressive regen set ups as well, so the brakes are used less.

          Sure, but a little rust because they weren’t used isn’t a problem, comes off when you use them, but is an instant fail. The brakes are not damaged or broken.

          All brakes rust when not used. If you drove around in the rain today, then didn’t drive for a few days, you’ll probably have a little rust on your brakes. You go for a drive and then it’s gone.

          If you take your car in for a pre-inspection report, and they see some rust on the brakes, they will tell you to drive it around a bit using the brakes a lot before taking it in to be inspected.

          it’s not an actual problem, and not indicative of a poor quality vehicle.

          Edit: To be clear - the drivers should be using the brakes more to clear them so it doesn’t build up to excessive amounts which may be a problem at some point, but the test fails them well before it’s an actual problem.

          Edit: Also, where the model 3 failed a lot outside of the brakes was the front suspension. There are legitimate problems with the front suspension on the older Model 3s. Those are legitimate fails and are a quality issue (there’s even a service bulletin for at least one of the problems)
