Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Summary of Safety Event: While traveling at highway speeds with active traffic behind me, the vehicle’s Advanced Driver Assistance Systems (ADAS) suffered an un-commanded, severe "phantom braking" event. The vehicle aggressively engaged the emergency service brakes and decelerated rapidly with absolutely no obstacles, pedestrians, or vehicles ahead. This sudden, violent deceleration created an immediate and high-risk rear-end collision hazard.Cascading Component Failures:In tandem with the dangerous autonomous braking behavior, the vehicle's electronic architecture (E³ 1.2 platform) is exhibiting chronic software instability. The High-Performance Computing infotainment stack continuously enters an internal network routing loop, displaying "Hotspot Reconfiguring" error messages. This completely crashes the cloud connectivity, signs out the primary driver profile, and force-reboots the central MMI display screen and wireless Android Auto interfaces mid-drive.Manufacturer Actions & Hazard Status:I have contacted the manufacturer (Audi of America) and local dealership service networks regarding these systemic software and safety issues, which Audi documents under master overview Technical Service Bulletin (TSB) 2081477. The vehicle currently poses an active safety risk to myself and surrounding motorists due to unpredictable braking behavior. The manufacturer has not yet provided a date to flash the corrected firmware containers (KD2* software update) to resolve the sensor fusion logic flaws.
