2019 Audi E-Tron electrical system 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…”

“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 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.”

“My 2019 Audi e-tron will not charge. The charging indicator turns red after a few seconds and charging stops. The issue happens with both my home charger and Electrify America public chargers. The vehicle does not make the normal charging connection/clicking sound. This appears to be a charging system or high-voltage electrical issue. I am concerned about a potential safety defect because the vehicle cannot reliably charge and may leave the vehicle unusable. We have had a lot of heavy rain recently, and I am concerned that moisture or water intrusion may be related to the charging failure. The vehicle will not charge and the charging light turns red after a few seconds. The issue occurs with both my home charger and Electrify America chargers.”

“am writing to file a formal complaint regarding my recent experience with the service department at Audi of Cherry Hill concerning my Audi e-tron. My vehicle remained at your dealership for approximately four weeks, during which time no repairs or meaningful progress were made. Instead, I was informed that I would need to approve approximately $13,000 in diagnostic fees before the vehicle would even be inspected or touched. I find this completely unreasonable and unacceptable, particularly given that my vehicle sat idle at your facility for an extended period without any justification. In addition, I am extremely dissatisfied with the customer service and conduct of an employee named Khern. He explicitly identified himself to me as a manager; however, after speaking with other staff members, I discovered he is not a member of management and works at the service intake desk. Furthermore, when I requested to speak with the actual service manager or another member of leadership to discuss my concerns, Khern actively refused to contact them or allow me to escalate the matter. As a customer, I expect honesty, transparency, and the ability to speak with management…”
