Defect
Bugatti (Bugatti) is recalling certain 2017-2020 Chiron, 2018-2020 Chiron Sport and 2020-2021 DIVO vehicles. After an ignition cycle, the Electronic Stability Control (ESC) does not automatically default back to the full-function original mode if the Handling Mode is selected on the Drive Mode switch.

Safety Risk
If the Handling Mode is activated, the ESC System goes into Sport mode. After an ignition cycle, the ESC does not default to the original default mode (ESC Normal Mode). After restarting the car, the Drive Mode remains in Handling mode affecting the ESC performance, increasing the risk of a crash.
