NHTSA Complaint #11420090 — 2020 CADILLAC XT6

Cadillac Case number is 9-6766521074. The Cadillac CT6 has a flaw in the intelligent braking assist(IBA) software. When no collision is imminent, pushing the brake even slightly results in extremely hard overbraking causing all items to fly forward. There is no way to turn off IBA without disabling the entire Automatic Emergency Braking System. To be clear, it is OK that the car senses inaccurately a collision and it is OK to apply the Automatic Emergency Braking Logic, the problem is that the Intelligent Braking Assist is too hard when a crash is not imminent and this will cause following cars to rearend the XT6 when no hazard is expected/present. As an interim, please direct Cadillac that they update there system preference software to allow customers to turn off Intelligent Brake Assist (IBA) independently while still keeping Automatic Emergency Braking (AEB).
