2023 Audi A4 Driver Assist & ADAS Problems

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 G’s, confirming the severity of the impact. Dash camera footage also documents that the systems failed to intervene before the collision. My primary complaint is not about the airbags but about the malfunction of the lane assist and radar systems and the manufacturer’s refusal to provide the requested reports that would verify the failure. When I requested the radar and lane assist reports from the manufacturer after their inspection, they admitted they would not provide them. Instead, they stated there was no defect. 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, but for all owners of this model. I can provide supporting materials upon request, including dash camera video, the full Bosch crash data report, and correspondence with the manufacturer. My concern is both the malfunction itself and the lack of transparency. Without access to the radar and lane assist data, owners cannot verify that the advanced safety systems they rely on are functioning properly. This failure and refusal to provide proof of system performance must be addressed to protect other dri INFORMATION REDACTED PURSUANT TO THE FREEDOM O

The vehicle erroneously applies sudden emergency braking (Audi Pre Sense) without conditions warranting system activation. This malfunction occurs at the most dangerous of times, mostly while making left turns. Vehicles behind do not expect the vehicle ahead to suddenly stop which is going to cause an rear-end collision, and the timing for turning across lanes of traffic is leading to the potential front-end collision with opposing traffic. The sudden activation is unbelievably jarring and has caused shoulder and neck pain. This matter has been brought to the attention of the dealer on multiple occasions but codes are not produced for activation and I was told there is no "black box" to look at data history. This issue has been brought to the dealer's attention on 6/1/24, 12/21/24, & 1/2/25. The most recent incident occurred on 4/30/25 at approximately 2:00 P.M. during the same condition of making a left turn.
