Rusty brake discs or a poor contact pattern because the brakes are seldom used (regenerative braking) (Model 3 and Model Y)

Engine / equipment

Brake discs and pads: Tesla Model 3 and Model Y

Period mentioned

2019–2025

Symptoms

Usually nothing is felt while driving: it shows up at the inspection, with rusty discs or a poor contact pattern. The TÜV warns that braking performance can drop.

Possible cause described

With regenerative braking (“one-pedal driving”) the brakes hardly work and surface rust stays on the discs because the pads do not wipe it off (auto motor und sport). In the 2026 TÜV report published by AUTO BILD, the Model Y discs fail 2.8 % of the time because of a poor contact pattern (average: 1.1 %), and on the Model 3 discs with a poor contact pattern top the defect list.

Check for the garage

The head of the TÜV association advises using the brake pedal deliberately on a regular basis. Before the MOT or periodic inspection, and when buying one second-hand, have the discs and pads checked.
