While driving southbound on [XXX] near [XXX] in Mississippi, the advanced driver-assistance systems (lane assist and radar) did not operate as designed. At highway speed, the vehicle gave no warnings, no steering correction, and no radar-based intervention prior to a severe crash. This failure of the safety systems placed my life at extreme risk. The vehicle had been properly serviced at an authorized dealer, and there were no warning lights or fault messages prior to the incident. After the crash, nearly all airbags deployed, but the crash data recorder shows abnormal timing information. The Bosch Event Data Recorder (EDR) captured a force of 292 Gâs, confirming the severity of the impact. Dash camera footage also documents that the systems failed to intervene before the collision.

This is unacceptable because the data clearly exists, and withholding it prevents owners from knowing whether these safety systems can be trusted. The fact that these systems failed in a critical moment and the manufacturer is unwilling to disclose the information raises a serious safety concern not just for me, bu
