NHTSA Complaint #11700974 — 2024 AUDI Q8

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.
