IMPORTANT SAFETY RECALL Miller Motorcars 275 West Putnam Avenue Greenwich, CT 06830 USA This notice applies to your vehicle, Vehicle Identification Number (VIN): VF9SP3V3XKM795123 Model Year/Model: 2019 / Chiron NHTSA: 20V-732 Dear Valued Bugatti owner, RE: RECALL – Electronic Stability Control/FMVSS 126 (BUGCR033) This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. BUGATTI Automobiles SAS has determined that a non-compliance relating to motor vehicle safety standard 126 (FMVSS 126) exists in all BUGATTI Chiron, Chiron Sport and DIVO vehicles delivered from Molsheim France before 18th November 2020. Our records show that you are the owner of such a vehicle. What is the issue? The ESC (Electronic Stability Control) System does not automatically default back to fully functional mode, if the car has been left in handling mode on the steering wheel ESC button, after switching off and then switching back on the vehicle ignition. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, “Electronic Stability Control Systems.” This can mean that the last setting of the ESC prior to the ignition being switched off is then maintained when the vehicle ignition is engaged again. The FMVSS 126 requirement is the ESC should reset to fully functional mode on switching off the ignition. What will we do? To correct this, your authorized BUGATTI Partner will apply a software update to a number of vehicle control units. This software update will also fix minor bugs. This software update can take between 1 hour and approximately 14 hours to complete depending on which version of Software your vehicle is currently operating at and will be performed for you free of charge. If the sole purpose of the vehicle visiting the authorized BUGATTI Partner is for the application of the required software update then all related transport costs will be covered under Warranty by BUGATTI.
