2024 Audi Q4 E-TRON

I am reporting multiple ongoing electrical system malfunctions on my 2024 Audi Q4 55 e-tron SUV that create a safety risk, including sudden loss of functionality and warnings instructing me to stop driving. These issues began approximately two months after I purchased the vehicle and continue to occur. The car has been at Audi Bellevue for the second times since 11/5/2025. The car with error was initially dropped off at the dealership on 09/27/2025. The vehicle repeatedly and sporadically displays the following warnings (even when at Audi dealership. “Electrical system". Malfunction! “Safety system: fault” See owners manual “Vehicle sound: malfunction” Pedestrians cannot hear vehicle. Please contact service (when the car is being driven) During some of these events, vehicle drivability is compromised, systems shut down unexpectedly, and the car instructs me to exit or stop driving. This creates a potential risk of loss of power while driving. The vehicle has been at Audi Bellevue now for approximately four weeks since 11/5/2025 attempting diagnosis and repair. I was informed that the dealership opened a TAC (technical assistance case) with Audi corporate, but they have not been able to resolve the issue. I was also told there is a related issue affecting the Audi e-tron GT and that the fix for that model cannot be applied to my Q4. My vehicle appears to be part of the national recall 25V125000 (Audi recall 93FR) covering the on-board charger/DC-DC converter (OCDC) that can fail and result in 12-volt battery depletion and loss of drive power. I have not been informed whether parts for this recall are available or whether my vehicle has been repaired under this recall. This is a safety-critical issue, and the repeated failures and warnings make the vehicle unreliable and potentially hazardous to drive. I am requesting that NHTSA document this defect and investigate whether other 2024 Audi Q4 e-tron SUVs are experiencing similar electrical failures.
