2025 Audi Q4 E-TRON

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.
