Concern: Customer states: speed of charging at Superchargers is topping out at lower

speeds then previously observed. This has happened at multiple superchargers recently.

Pay Type: Goodwill

Corrections: Supercharger General Diagnosis Conclusion: No Trouble Found

Review vehicle logs and verify charging is topping out a lower rate than observed on

earlier DC charging sessions. According Tesla engineers once vehicle has been DC fast

charged over a specified amount, the battery management system restricts DC charging to

prevent degradation of the battery pack. According Tesla engineers, this vehicle has seen

significant DC fast charging and is now has permanently restricted DC charging speeds.

Important to note, supercharging will always still be available to the vehicle and the battery

pack has not yet experienced significant degradation due to the amount of DC fast

charging performed on the pack up until this point in time. Vehicle is operating as

designed.
