The 2020 Bugatti Chiron has 3 recalls, the most serious involving a rear left-hand driveshaft that can break and shed parts onto the road, creating a hazard for following traffic and raising the risk of a crash.
On the electronics side, a software issue with the electronic stability control means the system does not automatically return to its full normal mode after the car is restarted. If the driver had selected Handling Mode during a previous drive, stability control stays in Sport mode the next time the car is started without the driver necessarily knowing, which reduces the system's ability to help correct a skid. There is also an instrument cluster issue where the audible chime that warns a driver their seatbelt is not buckled may not sound at startup, leaving the driver without any alert that the belt is unfastened before getting underway.
