Owner complaint summary

1. What component/system failed, and is it available for inspection? The HVAC (heating/ventilation/air-conditioning) system — specifically the A/C evaporator and its condensate drainage — in my 2022 BMW X5 (G05). It emits a recurring musty/vinegar-like odor, consistent with microbial contamination on the evaporator. The system remains installed in the vehicle and is available for inspection upon request. 2. How was safety put at risk? The odor indicates mold/microbial growth in the cabin air supply, which is a respiratory air-quality concern for the driver and passengers . A strong odor on start-up is also a distraction that draws my attention away from driving . BMW's own bulletin attributes the odor to microbial contamination on the evaporator. 3. Reproduced/confirmed by a dealer or service center? I recently scheduled a service for next Wednesday. 4. Inspected by manufacturer, police, insurance, or others? Not yet escalated to BMW corporate (no PUMA/TSARA technical case opened). Not inspected by police or insurance. 5. Warning lamps/messages/symptoms, and when they first appeared? No warning lamp or dashboard message is associated with this condition [true — odor triggers no telltale]. The symptom is the odor itself: a musty/vinegar smell fro
