The lawsuit claims the chatbot stopped recommending medical care and told him to take it easy while he had episodes of dizziness and weakness. Winters says the symptoms went on for six weeks and were wrongly attributed by the chatbot to something else. When pain forced him to hospital, massive pulmonary embolisms were discovered. He filed a negligence suit in California against OpenAI and Sam Altman. OpenAI says ChatGPT is not supposed to work this way. The claims are allegations and have not been tested in court.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null,"primary_risk":"RK19"},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"severe","severity_because":"Safety-of-life test met: the sentence states a life-threatening pulmonary embolism and an ordeal that could have resulted in his death, affecting one person.","harm_class":["bodily"],"affected_description":null,"protected_class_involved":null,"data_categories_exposed":[],"loss_range_usd":null,"reversibility":null,"downstream_exposure_count":null},"evidence":{"sources":[{"url":"https://www.jezebel.com/chatgpt-openai-lawsuit-health-bad-medical-advice-embolism-scott-winters-responsibility","publisher":"Jezebel","date":"2026-07-22","type":"press","title":"OpenAI Faces Its First Lawsuit Over ChatGPT Offering Near-Deadly Medical Advice -

The incident dates are not stated beyond the 2024 start of conversations and the six-week symptom period, so date_occurred is omitted. The lawsuit date is taken from the article's embedded post stating Today on 2026-07-22. The trigger, root cause, responsible party and adversarial actor are not established by the sources and are omitted; the root_cause_detail reflects only the claimant's account. The D1 failed outcome is my inference from OpenAI's statement that ChatGPT is not supposed to work this way; the source does not name a control. Detection method victim is my judgement from the hospital discovery sentence. Severity severe rests on the safety-of-life test as I read it for a single person. Model version, lifecycle stage, intended use, country, industry and remediations are not stated and are omitted. Agent involvement is not stated as autonomous, so agent_involved and failure classes are omitted.
