CRITICAL SAFETY DEFECT: HIGH-SPEED BRAKING SURGE & ELECTRICAL FAILURE Life safety concerning ! 1. Braking Failure at Highway Speeds: The vehicle exhibits a severe safety defect involving unintended acceleration/surging while braking. While driving in 'D' (Drive) mode at approximately 50 MPH, when applying the brakes to stop for traffic/red lights, the vehicle fails to decelerate immediately. Instead of slowing down, the vehicle surges forward against the braking input, feeling like a loss of regenerative braking authority. This results in extended stopping distances and near-miss collision risks at high speeds. 2. Charging & Electrical System Failure (Suspected Recalls): The vehicle suffers from persistent electrical failures that the dealer dismissed as "user error" or a "bad plug," but which match known Audi safety recalls: (A)AC & On-Board Charger Failure: The vehicle threw "AC System" error codes and fails to charge reliably, shutting off after short periods. This mirrors symptoms of Recall 93FR (High-Voltage Battery/On-Board Charger), risking a 12V battery stall. My car model was among those impacted recalled car dearies even now it is not listed as one of the recall Model by VIN#, I strongly suspected my car has same defect. Many websites have address this life threatening issue would [XXX] ." (B):Charging Cable Overheating: The included 220V charging cable is suspected to be defective (matching Recall 93U6), which poses a fire risk at the outlet. (C)Interior Voltage Instability: Wired USB-C ports cut power/disconnect devices less than 5 minutes of use. 3. Dealer Negligence: The dealership (Audi Tysons Corner) failed to diagnose these issues ("Could Not Replicate"), refused to replace the recalled charging cable, and released the vehicle with active "Inspection Due" warning lights. The vehicle is unsafe to drive. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing a safety complaint regarding my leased 2025 Audi Q4 e-tron, leased new with under 500 miles and now at approximately 8,200 miles. The vehicle is available for inspection upon request. The vehicle has ongoing brake-related issues affecting low-speed operation: a rough or grinding brake pedal feel and intermittent brake squeal during rolling stops, turns, and parking maneuvers. The most concerning issue is unexpected parking brake or emergency braking activation during low-speed pull-off and parking maneuvers, causing the vehicle to abruptly jolt to a stop. This has happened approximately four times between March and July 2026, beginning around 6,000 miles, including while pulling to the roadside and while parking with my foot already on the brake. No other vehicle was nearby during these events, and the behavior is not consistent or predictable, creating a risk of unexpected stopping during normal low-speed operation. This does not match normal EV regenerative braking based on my experience with other EVs, including another Q4 e-tron, and appears specific to this vehicle. I reported these concerns to authorized Audi dealers and Audi Customer Experience. In February 2026 I brought the vehicle to an authorized dealer for a brake-related appointment; a technician did not inspect it because the service associate said he did not think anything was wrong, and I later learned the appointment was canceled rather than documented. I also raised these concerns with a second authorized dealer during a one-year service visit and on two additional occasions. The problem has not been reproduced or confirmed by a dealer to my knowledge, and has not been inspected by police, insurance, or an independent service center. I am not aware of warning lamps before the jolting events. I am concerned the vehicle may have a defect involving the service brakes, parking brake, emergency braking system, software, sensors, or control-system behavior.

Received a low pressure warning and got off the freeway at the next exit, less than 1/2 mile. Unable to stop on freeway. Before even changing lanes the tire blew out all pressure, total failure. Within 15 seconds of low pressure warning. Stopped immediately after exiting freeway and observed the tire was shredded (see pictures).
