2024 Audi Q8 Electrical System Problems

Owner: Jyima Ofori-Atta Vehicle: 2024 Audi Q8 E-Tron (55) VIN: WA15AAGEXRB031696 Current Mileage: Approximately 6,335 miles Dealer: Audi Van Nuys, Sherman Oaks, CA Lease Start Date: February 1, 2025 Car charging issue I recently received my vehicle back from service following an extended stay related to recurring charging system and software issues. While the vehicle has been returned to me, my primary concern is the likelihood that the same charging failure will occur again, as it has multiple times in the past. Due to the history of unresolved charging failures and the absence of a clearly communicated permanent fix, I am extremely concerned about the vehicle’s reliability moving forward. Since taking delivery of the vehicle, I have experienced multiple charging system failures that rendered the vehicle unable to charge and therefore inoperable. Charging failures occurred unpredictably and without warning. The issues were not limited to a single charger and occurred using both home and public charging stations. When the charging system fails, the vehicle cannot be driven once battery charge is depleted. These failures have resulted in repeated loss of use and extended service visits. Because this is an electric vehicle, reliable charging is essential to basic operation. Given the history of failures: I am fearful of relying on the vehicle for daily transportation. There is ongoing concern about being stranded if the charging system fails again. The unpredictability of the issue has created significant stress and hesitation in using the vehicle as intended. This concern is not hypothetical; it is based on repeated past incidents.

CHARGING SYSTEM DEFECT: The manufacturer-supplied portable charger (rated 9.6kW at 240V/40A) delivers only 7.4kW — a 23% shortfall. The authorized dealer confirmed this measurement in March 2026 but refused to repair, stating "no issues." The charging rate also degrades over time without manual reset. The vehicle also intermittently fails to charge at DC fast charging stations — it begins charging, then stops within minutes displaying "Malfunction of charging" error. Other EVs charge normally at the same stations. SAFETY RISK: Charging failures create a stranding hazard. The vehicle can fail to charge at public stations without warning, leaving the driver unable to complete trips. REPAIR HISTORY: 5+ visits to two authorized dealerships over 10 months (May 2025–March 2026), 16+ days out of service. No fix — returned each time as "no fault found" despite video evidence of failures shown to dealer at every visit. Manufacturer corporate support also failed to resolve. Dealer found DTCs for charger communication faults. A demand letter was sent to manufacturer — no response received. Vehicle and charger available for inspection.

1. Failed/Malfunctioned Component: March 2025 - Air Conditioning (A/C) control valve, May 2025 - A/C line and seals. 2. Safety Risk: I heard an explosion underneath the vehicle shortly after parking the vehicle in a shopping center. Upon quick inspection, I did not initially observe any obvious broken parts, components, nor any warning lamps, messages or symptoms. The following day while charging the vehicle in my garage, I noticed a fluid leak emitting from under the vehicle. The fluid was identified as R1234YF refrigerant, which is flammable. The risk of that fluid igniting is even greater while the vehicle is charging. 3. The problem was reproduced by the dealer under both incidents (A/C control valve failure & A/C lines and seals explosion) and confirmed as a manufacturer defect. 4. The vehicle was inspected, serviced, and repaired at an authorized dealership on two occasions. 5. Warning lamps, messages, or other symptoms? Symptom in first instance was failure to blow cold air. Symptoms in second incident - fluid leak was detected, shortly after turning on the vehicle A/C failed to blow old air.

Our Audiu Q8 has had a host of safety issues since purchased in December 2023 and we have been denied or delayed on a buyback twice. The vehicle has been unable to be moved 3 times due to battery (12V and relay) issues that left my wife and [XXX] stranded at home. On one occasion the vehicle could not be moved by the tow service whatsoever. The charging system cable (known to cause fire hazard by Audi with open safety bulletins) created a fire in our 240 outlet box and also melted the plug and connected cable. The vehicle also continues to read road signs on exit ramps and hard brake check almost causing accidents while driving on the highway with cruise control. The feature for traffic sign recognition is tuned off but the vehicle continues to do this hard and sudden brake checking. Audi continues to drag their feet on repairs and still has not reimbursed us for electrical expenses from the fire damage over 6 weeks later.

From the first day I purchase the vehicle, even when the sales person was walking me through the vehicle, the vehicle window was constantly retracting itself lower when i tried to close it. When the window is half way open, and the driver is trying to close the window, the window automatically retracts and lowers the window. causing distraction for the driver and safety hazards from the road and environmental conditions.

I have two Q8 Etron, and this q8 is also having the same issue as my other q8. When the windows are open half way, and the driver is trying to close the window because the car is moving faster speed, the window automatically retracts and opens the window even lower. this is really distracting to the driver especially when there is a safety hazard on the road or the weather. please address this issue to improve safety of the vehicle
