Faults that affect 2026 cars
- Critical severityFrequency: RareTraction batteryTotal failure of the traction battery in the Tesla Model 3 and Model YThere are isolated cases of a traction battery being beyond repair in the Model 3: fiches-auto.fr cites a Long Range with 70,000 km and a little over four years old whose battery, valued at around €14,000, was replaced under warranty. Aviloo's measurements show normal degradation in the vast majority of units.Repair: €14,000
- Medium severityFrequency: OccasionalChargingFailure of the on-board charger or charging port on the Tesla Model 3 and Model Yfiches-auto.fr records owners of the Model 3 and Model Y reporting on-board AC charger faults, mobile charging cable faults or port locking that prevent charging, sometimes from the day the car was delivered. It is a minority problem, not a widespread one.
- High severityFrequency: RareElectric motor and reduction gearFailure of the electric motor or traction unit on the Tesla Model 3 and Model Y that immobilises the carElectric motor faults on the Model 3 and Model Y are rare: fiches-auto.fr records one case of a motor defect that left a dual-motor Model 3 Long Range immobilised, and ADAC places the Model 3 among the electric cars with the fewest faults.
