My 2019 Audi e-tron developed a sunroof leak. On [XXX], Audi Exchange in Highland Park, IL repaired it as a known issue partially covered by warranty; I paid $526.53. On [XXX] it leaked heavily again from the same area, soaking the headliner, dashboard, carpet, foot wells and seats. The dealer said a different issue caused it; I paid $388.88 more. I had never had an electrical problem before. While the car was at the dealer, they charged it, and an orange battery warning and “Electrical System Malfunction” message appeared. They confirmed a charging-system fault but refuse to diagnose it and expect me to pay. The service manager told me to pick up the car and that the matter was closed. SAFETY RISK: The e-tron has a high-voltage system. Water exposure this extensive can corrode wiring, connectors and control modules, causing failures that may not appear right away. A charging fault of unknown cause could lead to charging failure or electrical problems while driving. I do not consider the car safe until the cause is found and water damage is ruled out. Only Audi Exchange has inspected the car, and no one has checked whether the water caused the fault. The car is available for inspection; please preserve all parts and records. I REQUEST THAT AUDI OF AMERICA AND AUDI EXCHANGE: Inspect for water damage and corrosion to wiring, connectors, modules and charging components. Determine whether the water caused the fault. Explain why the car leaked again after the first repair. Provide

What owners reported
Newest filingsWhat component or system failed or malfunctioned, and is it available for inspection upon request? The component that failed is high-voltage battery cell 6 (part of the lithium-ion traction battery pack assembly). The physical vehicle and its high-voltage battery system are currently held at Wilsonville Audi in Oregon and are fully available for physical or digital diagnostic inspection upon request. How was your safety or the safety of others put at risk? The terminal failure of the internal battery module triggered an abrupt high-voltage electrical system isolation fault, presenting an immediate risk of sudden propulsion loss while driving at highway speeds. Furthermore, according to the manufacturer’s open federal safety campaign (NHTSA Campaign 23V867 / 93V2), this exact internal module self-discharge condition creates a documented critical thermal runaway and vehicle fire risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The failure has been formally reproduced, diagnosed, and confirmed by an authorized dealership, Wilsonville Audi. Their factory diagnostic equipment pulled a permanent, active safety lockout fault under Trouble Code B1D9EF1, confirming a catastrophic voltage drop and safety isolation breakdown at the cell level. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been physically inspected and scanned by the manufacturer's authorized
The component that failed is battery cell 6 within the internal high-voltage traction battery pack assembly. The vehicle is currently experiencing a severe high-voltage isolation/safety breakdown, flagging diagnostic trouble code B1D9EF1 while running on manufacturer software version 0490. The vehicle and its high-voltage battery pack are currently located at an authorized dealership and remain fully available for inspection upon request. The failure of an internal high-voltage battery cell creates an imminent risk of a sudden, uncommanded high-voltage electrical powertrain shutdown while traveling at highway speeds. This condition causes an immediate loss of motive propulsion, forcing the vehicle into a hazardous limp-mode or staging a complete shutdown on live roadways, drastically increasing the risk of a high-speed rear-end collision. Furthermore, internal cell failures and isolation faults of this nature present severe underlying thermal management risks within the high-voltage pack layout, endangering vehicle occupants and nearby property. Yes. The high-voltage failure and the specific failure of battery cell 6 were officially reproduced, diagnosed, and confirmed by the authorized dealership, Wilsonville Audi, under Repair Order 211793. The vehicle has been physically and electronically inspected by authorized factory technicians at Wilsonville Audi. No inspections have been conducted by police or insurance representatives at this time. Prior to the breakdown, the vehic
The contact owns a 2019 Audi E-Tron Quattro. The contact stated that the messages "Electrical System Malfunction", "Please Stop Vehicle", and a message for the battery were displayed. The vehicle was taken to the dealer, where it was repaired under NHTSA Campaign Number: 23V867000 (Electrical System); however, the failure recurred a year later. The vehicle was taken back to the dealer, where it was diagnosed and determined that the high-voltage battery cells needed to be replaced. The manufacturer was notified of the failure by phone but provided no assistance. The contact received a response by email. The failure mileage was approximately 30,000.
The contact owns a 2019 Audi E-Tron Quattro. The contact stated that while driving at various speeds, the vehicle intermittently failed to stop while depressing the brake pedal. The contact was forced to depress the brake pedal to the floorboard to stop the vehicle. Upon investigation, the contact discovered NHTSA Campaign Number: 24V621000 (Service Brakes, Hydraulic); however, the VIN was not included in the recall. Additionally, the contact stated that there was water leaking into the vehicle from the dome light. The contact stated that water had accumulated around the sunroof and believed that the sunroof was the source of the leak. The failure mileage was approximately 56,000.
Multiple times and at random times the vehicle reports "Central locking: malfunction! See owner's manual". When this happens, the driver's door is completely locked and driver cannot exit the vehicle. Door cannot be opened from outside either. So far this has only caused real delays, but this is a safety issue. I have reported the problem to Audi dealer but they advised that Audi has instructed them to apply software updates and not replace any parts. While the issue continues to re-appear, the dealer has dragged their feet to the point that vehicle is now out of the standard warranty. In researching the issue, this seems to be widely spread on Audi after 2019. Mine vehicle is a 2019 Audi e-tron quattro prestige.
THE REAR COOLANT BOTTLE FOR THE DRIVE MOTOR IS COMPLETELY FULL, HV FAULTS ARE STORED. BATTERY IS IN "WARNING" CONDITION, J840 STORES INTERNAL MALFUNCTION FAULTS. ADDITIONAL DIAGNOSIS IS NECESSARY FOR THE HV SYSTEM, AND THE REAR DRIVE MOTOR WILL NEED TO BE REPLACED. FOUND CELL IMBALANCE FAULTS STORED, FOUND J840 BATTERY MODULE IS FAULTY AND MUST BE REPLACED. FURTHER DIAG IS NECESSARY, MULTIPLE FAULTS ARE PREVENTING THE VEHICLE FROM MOVING, FAULTS SET ON 06/22/26. HV AND DRIVE MOTOR FAULTS ARE NOT LIKELY TO BE RELATED TO ANY IMPACTS OR DAMAGE, MALFUNCTIONS ARE ELECTRICAL AND INTERNAL.

No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
