2019 Audi E-Tron problems

“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…”

“What 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…”

“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…”

“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.”

“Airbag detection system continues to malfunction. When driving at random times it states the detection system is currently unavailable as well as all the function buttons on the steering wheel.”

“Dear Audi Product Safety Division and NHTSA Office of Defects Investigation, I am writing to formally document a safety defect in my 2019 Audi e-tron Prestige (VIN [XXX] ), which exhibits the same brake-system failure described in Audi’s brake-booster recall – Campaign 46P6 / NHTSA Recall 24V-621, despite Audi’s system not listing my VIN as covered. Vehicle Details Make/Model: 2019 Audi e-tron Prestige VIN: [XXX] Build Date: 05/19 (per manufacturer label) Mileage: [insert current mileage] Primary Location: Lynwood, Illinois Defect Summary My vehicle repeatedly displays: “Parking Brake Malfunction” and “Brake System Fault” warnings. A clicking noise or resistance when pressing/releasing the brake pedal. The brake pedal occasionally fails to return fully to its normal position. On one occasion, the vehicle rolled slightly while parked. These symptoms match those described in Audi’s recall 46P6, which involves improper assembly of the bolt connection between the brake-pedal input rod and brake-booster actuator rod. Interaction with Audi Corporate On [insert date], I contacted Audi of America Customer Experience (1-800-253-2834) to report this as a safety issue.…”
