There is very little public fault data for these units; recent European recalls do not affect the drivetrain (airbag, seatbelt and brake fluid).[3][4]
Faults that affect 2026 cars
- Critical severityFrequency: RareTraction batteryHigh-voltage battery or battery management (BMS) faultNormal degradation is low: Tesla publishes an average loss of 12% at 320,000 km. Real battery faults are rare, with a few BMS cases and replacements before 250,000 km cited by fiches-auto.fr.
- Medium severityFrequency: OccasionalElectric motor and reduction gearVibrations from worn front driveshaftsOn dual-motor versions, the front driveshafts can wear and cause vibrations under hard acceleration. Auto Bild cites it on the Model X and fiches-auto.fr records several cases; the motor and reduction gear assembly does not usually fail.
- High severityFrequency: RareElectric motor and reduction gearElectric motor or drive unit faultThe motor and reduction gear units of the Model S and X are considered robust: Auto Bild hardly records any faults. fiches-auto.fr says some owners have replaced the motor or battery before 250,000 km, though without frequency figures.
