This is a follow-up to complaint #11714226 regarding an ongoing safety defect. The defect has now resulted in a crash. The vehicle experiences repeated unintended braking at highway speeds (50–79 mph) without driver input and with no obstacles present. During multiple events, the steering becomes temporarily unresponsive or “locked,” preventing driver control. The vehicle has also exhibited unintended lane departures, erratic lane changes, and unexpected acceleration following braking. …
