SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
At least a dozen times, while accelerating from a complete stop, the car has experienced sudden unintended very hard braking without driver input. After very hard brake, car falls out of gear and needs to be restarted and put back in gear. -In clear, dry, temperate weather -Day and night -In drive and reverse -While accelerator engaged -Not touching brake pedal -No obstacles, pedestrians or vehicles present that would require braking -No warnings, alerts or messages on screen -Occurs randomly, nothing to indicate braking is needed -Most recent incident, on flat, familiar road, clear, temperate weather, no obstacles, car unexpectedly braked after accelerating from traffic light, fell out of gear and would not go back into gear for several minutes, resulting in near rear-end collision with multiple vehicles behind that did not expect sudden stop while accelerating. Eventually car would drive a short distance then hard brake, slip out of gear, not be able to drive. This was repeated 4 times before finally being able to drive without failure. -Audi inspected, could not reproduce the issue. It occurs very randomly, so it’s difficult to reproduce on demand. -No fault codes were found or stored -Dealer said without being able to reproduce it there was nothing to be done. I asked for TAC case to be opened for assistance. They strongly refused but eventually agreed. Case was opened but immediately rejected (within minutes). Later they said it was rejected for missing info, including location of incidents, which they never asked me for and I could have provided. Sudden random very hard braking and going into park while accelerating, then not being able to drive, with no warnings or fault codes, is a safety hazard.This has happened many times over a year. Other vehicles can crash into an unexpected stopped car in traffic. The last time I came within a millisecond of a major crash.

AIR BAGS, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
As I began to move the car, the vehicle suddenly accelerated on its own. I attempted to brake before reaching the stop sign, but the car continued to gain speed. I estimate the vehicle reached approximately 60 mph. Within seconds, I collided with two vehicles and then a palm tree, sustaining a frontal impact. The entire incident occurred within approximately two to three seconds, during which the vehicle accelerated rapidly. Despite the collision, the airbags did not deploy, the seat belt did not lock, and neither the brake system warning nor the automatic braking system activated.

VEHICLE SPEED CONTROL, SERVICE BRAKES, ELECTRICAL SYSTEM
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)

Car had electrical malfunction warning please contact costumer support and car died and zero damage to the body or the car. But the side air bags faulty went off. This car had a prior recall on file for same issues of car dying off and clerical problems. I got this car in September 2025 and had issue with it within the second month of having this car. I was not told there was a prior recall at all.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was stopped in line at a drive through. The car started rolling (electric cars should not do that) so I tapped the brakes. The car started accelerating and I started braking hard and the car just sped up. Auto braking and collision warning did not kick in. The car slammed into the car parked in front of me and drove it forward about 10 feet. The driver has soft tissue injuries as do I. In the past, it has also lost acceleration while driving did not respond to the gas pedal. I frequently get warnings that the safety features are temporarily not working.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I purchased the Audi Q4 Etron new. The issue that I'm bring up is 'self-acceleration' I had the intial incident 10/2025 where the car self accelerated (Audi Case open) but can't reproduce which almost pin a kid between my vehicle and another vehicle. I was able to react quickly to prevent a death. Second time 'self-acceleration" was on 3/27/25. My son pulling into garage with my sitting next to him, the car self accelerated after coming to complete stop, jumped a pakring block and crashed into my garage wall. Dealer had the car for 2-3 weeks and still couldn't replicate. Third incident was 10/30/25 while at a complete stop in traffic leaving a parking lot, the car was at complete stop and 'self-acclerated' into the vehicle in front. This incident caused my vehcile to be total-loss by insurance. Audi case was also open and they said no fault and told me it's an insurrance matter. I believe there are many cases like mine and they are aware. There are lots of discussion on the defective 'self-accelreation' on Audi Q4 Etron. take a look at this link "https://www.reddit.com/r/etron/comments/16ta6qe/beware_of_the_q4_etron_sudden_acceleration/"

UNKNOWN OR OTHER
When vehicle is energized and in Neutral "gear" the vehicle makes no sound. I understand that federal safety standards indicate that when in this status, the vehicle should generate a sound so pedestrians can hear it. The vehicle does NOT generate a Vehicle Sound malfunction alert when this occurs (and it should). This condition is reproducible all the time. The service manager at Audi Dallas witnessed this condition and verified that it also occurred on a similar vehicle he had on the lot. I called NHTSA several months ago to report this, but I cannot find a record of it online so am repeating the report. If you do have a record of it, this is a redundant report.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Primary issue is electric shock hazard and limb dismemberment. It was confirmed by an Audi service tech that all Audi Q4s have dangerous gaps in every door. My child 8 years old got her finger caught between the panel and door frame. She could have cut or worse lost her finger should the door rapidly open or close. Wires are exposed leaving the easy situation of access to wires with sharp metal objects that a kid could do. Open door panels have sharp edges leading g to easy cuts. As the wires are colorful and visually appealing a kid would be enticed to try to acquire. The techs will not close the panel to frame since this is Audi’s deliberate design. Tech claims to have fixed but clearly was not touched. Audi should be required to redesign door paneling and reinstall proper paneling. All door paneling to the door frames should be closed and secured with zero gaps. Video claiming this normal is found here [XXX] &section=RECOMMENDATIONS&shouldOpenInspectionsReport=true INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
I purchased a new 2024 Audi Q4 e-tron. The first malfunction occurred in January 2025 when a dashboard warning appeared stating the vehicle was “unable to read traffic or road signs.” The dealer confirmed a front-camera sensor failure and replaced the camera under Repair Order #193312 (1/17/25 – 1/29/25) at approximately 397 miles. In February 2025, the vehicle displayed repeated “drive system malfunction” warnings and would not start reliably. The dealer determined the issue was linked to the 12-volt battery and replaced it under RO #194457 (2/24/25 – 3/14/25, 866 miles). Soon after, persistent drive-system and electrical faults continued (RO #195096 and #195241 from 3/17 – 3/27 at 866–1,081 miles) but no repair was completed. On 4/10/25, an “AWD malfunction” occurred, and the vehicle was towed. Under RO #195846 (4/10/25 – 4/25/25, 1,594 miles), the front electric motor/drive unit was replaced. The vehicle remained out of service for extended periods. I was provided an EV loaner during the initial repair in January and gasoline loaner vehicles thereafter. In June 2025 (RO #198283 at 3,161 miles), a factory recall for the onboard charger was performed. The warning “Pedestrians cannot hear motor sound” appeared both before and after the motor replacement, suggesting a persistent fault in the Acoustic Vehicle Alerting System (AVAS). These repeated electrical, sensor, and propulsion failures — all within 3,000 miles of use — raise concerns about the reliability and safety of the ADAS camera, drive unit, and pedestrian-alert system. Power loss and a nonfunctional pedestrian-warning feature could increase risk to the driver and others. The manufacturer has been notified, and both dealer and manufacturer-updated repair records — showing mileage inconsistencies between versions — are available for review upon request.
